Flender Gear Units for Lifting and Luffing Gears: Precision Engineering for Crane Applications

Cranes don't get a second chance when a gear unit fails mid-lift. Whether it's a container crane moving cargo at a busy port or a tower slewing crane on a construction site, the gear unit driving the lifting or luffing motion has to handle enormous torque, reliably, cycle after cycle, for years. This is exactly the demand Flender's gear units for lifting and luffing gears are engineered to meet.

This guide walks through what makes these gear units different, the two main series available, and where they typically get deployed.

Why Lifting and Luffing Gear Applications Need Purpose-Built Gear Units

Lifting gears (raising and lowering a load) and luffing gears (changing the angle of a crane's jib or boom) both demand something standard industrial gear units aren't always built to handle: very high torque combined with the need for parallel motor-and-drum arrangements, especially where large drum and motor diameters are involved.

Flender addresses this with a broad, application-specific range built specifically for crane duty — offering torques ranging from 10,000 Nm up to a substantial 1,400,000 Nm, covering everything from mid-sized cranes to some of the heaviest lifting equipment in the industry.

Flender CHG — Purpose-Built for Lifting and Luffing Gears

The Flender CHG gear unit is designed specifically for the demanding requirements of crane lifting and luffing applications, developed in close collaboration with crane manufacturers and built on decades of Flender's engineering experience in this exact field.

What sets the CHG series apart is its large overall center distance, which allows the motor and winding drum to be fitted in parallel — even where large drum and motor diameters are involved. This parallel arrangement is exactly what's needed for container cranes and bridge cranes, where space and mounting geometry constraints rule out a simpler in-line gear unit configuration.

Key benefits of the Flender CHG series:

• High torque capacity — built for the heaviest lifting duty cycles
• Great center distance without a special solution — achieving the parallel motor-drum arrangement as a standard offering, not a costly custom build
• Easy selection via Flender configurators — simplifying gear-unit dimensioning during the specification stage
• Drive and output shafts designed for high additional forces — built to handle the real mechanical stresses of crane operation, not just nominal torque
• Optimised gear-unit elements for peak loads — engineered specifically for the load spikes typical in lifting operations
• Reduced mass moments of inertia — supporting more responsive, controlled motion
• Torsionally rigid welded steel housing — built for long-term structural reliability under heavy, repeated loading
• Large transmission area — supporting a wide range of application requirements within one series

Flender Cylindrical Gear Units — The Universal Standard Range

Alongside the specialized CHG series, Flender also offers a comprehensive cylindrical gear unit range that covers a broad set of crane and industrial applications. This is Flender's most extensive gear-unit lineup, spanning 24 sizes across a torque range of up to 1,400,000 Nm, suitable for both horizontal and vertical mounting positions.

For crane applications specifically requiring a greater center distance, Flender also offers cylindrical gear units with 10 sizes up to 109,000 Nm built with that larger center distance in mind — giving project engineers flexibility without needing to jump straight to a fully specialized CHG solution.

Key benefits of the cylindrical gear unit range:

• Variable center distances — adaptable to specific crane-area requirements
• High flexibility for project-related special solutions — a standardized range that still accommodates project-specific needs
• Optimised sealing systems — delivering high service life on shaft-sealing rings, reducing maintenance frequency
• Above-average service life, low weight, and low noise — a combination that matters both for operational cost and for site working conditions

CHG vs. Cylindrical Gear Units — Which Do You Need?

• Need a large center distance for parallel motor-and-drum mounting, especially with large diameters, as a standard offering? The CHG series is purpose-built for exactly this.
• Need a broad, standardized range with short delivery times and strong price-performance across a wide torque spectrum? The cylindrical gear unit range covers most general crane and industrial gear-unit requirements.
• Need a greater center distance but don't require a fully specialized CHG solution? Flender's cylindrical gear units are also available in 10 sizes up to 109,000 Nm with extended center distance.

Both ranges share Flender's core engineering strengths — high torque capacity, reliability under demanding cyclic loads, and the extensive application experience built into every gear-unit series.

Where These Gear Units Get Used

Flender's lifting and luffing gear units are deployed across some of the most demanding crane and hoisting applications in the world:

• Container cranes — high-cycle, high-precision lifting at ports and terminals
• Bridge cranes — industrial and infrastructure lifting applications
• Casting cranes — heavy, high-temperature lifting duty in steel and foundry operations
• Tower slewing cranes — construction-site lifting with luffing jib control
• Offshore cranes — demanding marine environments requiring high reliability
• Drawworks — heavy lifting equipment used in drilling operations

Why Gear Unit Selection Matters So Much in Crane Applications

A gear unit failure in a crane isn't a minor maintenance event — it can mean a stalled lift, unplanned downtime at a port or job site, and in the worst cases, a genuine safety incident. Getting the torque rating, center distance, and mounting configuration right at the specification stage is what keeps a crane operating reliably through years of heavy, repetitive lifting cycles — which is exactly why Flender has built two distinct series to cover both specialized and standard crane gear-unit requirements.

Schneider TransferPacT Active ATS: 100A vs 320A — Smart Automatic Transfer Switching Explained

Backup power systems live or die by one thing: how fast and how reliably the switchover actually happens. A generator that starts perfectly is useless if the transfer switch controlling it is slow, unreliable, or gives the facility team zero visibility into what's actually happening during a power event. That's exactly the gap Schneider Electric's TransferPacT Active series is built to close.

This guide explains what the TransferPacT Active ATS actually does, what its LCD-HMI interface brings to the table, and how to choose between the 100A and 320A models based on your facility's load.

What Is the Schneider TransferPacT Active ATS?

The TransferPacT Active is an intelligent Automatic Transfer Switch designed for reliable switching between mains supply and a generator or alternate power source in low-voltage power distribution systems. It's built specifically for facilities where uninterrupted power isn't optional — industrial plants, commercial buildings, hospitals, and data centers.

The device continuously monitors voltage and frequency on both power sources. The moment it detects a mains failure, it automatically transfers the connected load to the backup source — and once stable mains supply returns, it switches back automatically, without anyone needing to intervene manually.

Both models in this comparison are 4-pole, supporting three-phase systems with neutral switching, rated at 400V AC / 50-60 Hz, and built to comply with IEC 60947-6-1, the international standard specifically covering automatic transfer switching equipment.

What Makes the "Active" Series Different — The LCD-HMI Interface

The defining feature of this series is its integrated LCD-HMI display, which gives facility teams real-time status monitoring, alarm visibility, configuration control, and both manual and automatic operation modes — all from a single interface built directly into the switch.

This matters more than it might initially seem. A basic transfer switch just does its job silently; the TransferPacT Active tells you what it's doing while it does it — which source is active, whether an alarm condition exists, and lets you switch into manual override for testing or maintenance without needing separate tools or a technician crawling through wiring diagrams. For facilities that need documented, auditable power event history, that visibility is a genuine operational advantage, not just a display for its own sake.

TA10D4L10H4TPE — 100A TransferPacT Active ATS

The Schneider TA10D4L10H4TPE is rated for 100A on a 100A frame size, with a utilization category of AC-33B — a category specifically covering motor loads and other mixed loads typically seen in transfer switch applications. This rating suits smaller-to-mid-sized facilities or sectional loads within a larger site.

Best suited for: smaller commercial buildings, departmental panels, or sectional backup power loads where the total connected demand stays within the 100A range.

TA63D4L3204TPE — 320A TransferPacT Active ATS

The Schneider TA63D4L3204TPE steps up significantly to a 320A rated current, built on a larger 630A frame size — meaning there's headroom within the same physical frame for future capacity needs. Like the 100A model, it shares the same 4-pole configuration, AC-33B utilization category, and LCD-HMI interface, but is engineered for substantially higher-capacity backup power applications.

Best suited for: data centers, hospitals, industrial plants, and infrastructure projects where the total connected backup load is significantly higher and power continuity is mission-critical.

Quick Comparison

Feature	TA10D4L10H4TPE	TA63D4L3204TPE
Rated Current	100A	320A
Frame Size	100A frame	630A frame
Poles	4 Pole (3 Phase + Neutral)	4 Pole (3 Phase + Neutral)
Utilization Category	AC-33B	AC-33B
Display	LCD-HMI	LCD-HMI
Control Type	Automatic + Manual	Automatic + Manual
Rated Voltage	400V AC	400V AC
Standard	IEC 60947-6-1	IEC 60947-6-1
Typical Application	Smaller commercial/sectional loads	Data centers, hospitals, large industrial plants

How to Choose Between the 100A and 320A Models

This comes down to one core calculation: your total connected backup load at this specific transfer point.

• Calculate the total kVA/kW of everything that needs to run on backup power through this ATS
• Convert that to equivalent current draw at 400V AC
• Select the model that comfortably covers that load, with reasonable headroom for future expansion — the 630A frame on the TA63D4L3204TPE, for instance, offers room to grow even within its current 320A rating
• For larger facilities, it's common to combine both — a 320A unit at the main incomer, with smaller-rated units like the 100A model for sectional or departmental loads

Where the TransferPacT Active Series Gets Deployed

• Data centers — where continuous power and real-time status visibility both matter
• Hospitals — life-safety critical loads requiring dependable, documented transfer events
• Industrial plants — protecting continuous processes from unplanned mains outages
• Commercial buildings — maintaining operations and life-safety systems during grid interruptions
• Infrastructure projects — large-scale installations where power continuity is a core design requirement

LAPP ÖLFLEX® Control Cables Explained: HEAT 180, CLASSIC 110 & CONTROL 110 Compared

Walk into any control panel or machine wiring setup, and the cable you pick determines a lot more than whether the signal gets from A to B. Temperature exposure, core count, flexing requirements, and voltage rating all shape which cable actually belongs in that specific application — and picking the wrong one shows up later as a failure nobody expected.

This guide compares three LAPP ÖLFLEX® control cables — the high-temperature HEAT 180, the standard CLASSIC 110, and the higher-core-count CONTROL 110 — so you can match the right cable to the right job.

Why Control Cable Selection Isn't One-Size-Fits-All

Control cables look broadly similar on the surface — multiple insulated cores, a protective outer sheath, flexible construction. But underneath that similarity, they're engineered for very different operating conditions: how hot the environment gets, how many separate signals or circuits need to run through a single cable, and how much flexing or movement the cable will see in service. Getting this match right is what keeps a cable performing reliably for its full service life instead of degrading or failing early.

ÖLFLEX® HEAT 180 GLS 3G1 — Built for Extreme Temperature Environments

The ÖLFLEX® HEAT 180 GLS 3G1 is a high-temperature resistant silicone insulated cable, purpose-built for harsh industrial environments where heat — not flexing or core count — is the primary challenge. It features fine-stranded tinned copper conductors, silicone insulation, and a braided glass fibre sheath with an additional galvanized steel wire braid for serious mechanical protection.

What sets this cable apart is its temperature range: -50°C to +180°C, remaining flexible even at low temperatures while withstanding sustained high heat that would degrade a standard PVC-insulated cable quickly. It's rated for 300/500V, comes in a 3G1 configuration (3 cores + green/yellow earth), and is both flame retardant and halogen free.

Best suited for: steel plants, glass factories, furnace construction, heating systems, and any industrial machinery operating in sustained high-temperature conditions where a standard control cable simply wouldn't survive.

ÖLFLEX® CLASSIC 110 7G0.5 — The Reliable General-Purpose Control Cable

The ÖLFLEX® CLASSIC 110 7G0.5 is a premium-grade flexible control cable built for everyday industrial control wiring — machinery, automation systems, and control panels where multiple signals need to be carried reliably without the extreme conditions the HEAT 180 is designed for.

This variant features a 7-core configuration at 0.5 sq.mm conductor size, using fine-stranded Class 5 copper conductors for good conductivity and flexibility. The PVC insulation and outer sheath are oil-resistant and flame-retardant, and the cable is rated 300/500V, with a temperature range of -40°C to +80°C fixed and -5°C to +70°C flexing. It complies with IEC and VDE standards, and includes color-coded cores with a green-yellow earth wire for straightforward identification during installation.

Best suited for: control panels, industrial machinery, conveyor systems, automation setups, HVAC systems, and machine tools — essentially the default choice for standard indoor industrial control wiring where extreme heat isn't a factor.

ÖLFLEX® CONTROL 110 16 x 0.75 1100V GY — Higher Core Count for Complex Wiring

The ÖLFLEX® CONTROL 110 16 x 0.75 1100V GY steps up significantly in core count, offering 16 finely stranded copper conductors at 0.75 mm² each — designed for applications where a single cable needs to carry many separate control signals or circuits at once, reducing wiring complexity in dense automation setups.

It carries a grey PVC outer sheath (GY) with strong resistance to oil, abrasion, and mechanical stress, is flame retardant, and notably supports a higher rated voltage of up to 1100V, compared to the 300/500V rating on the CLASSIC 110. Its temperature range matches the CLASSIC 110 at -40°C to +80°C, and it's built for both fixed installation and occasional flexible use.

Best suited for: industrial automation systems, control panels, machine tools, and conveyor systems where you need to run many control or power circuits through a single cable — particularly where the higher 1100V rating matters for your specific circuit design.

Quick Comparison: HEAT 180 vs CLASSIC 110 vs CONTROL 110

Feature	ÖLFLEX® HEAT 180 GLS 3G1	ÖLFLEX® CLASSIC 110 7G0.5	ÖLFLEX® CONTROL 110 16x0.75
Core Configuration	3G1 (3 cores + earth)	7G0.5 (7 cores)	16 cores x 0.75 mm²
Insulation	Silicone rubber	PVC	PVC
Outer Sheath	Braided glass fibre + steel wire braid	PVC (oil resistant)	PVC (grey, oil resistant)
Temperature Range	-50°C to +180°C	-40°C to +80°C (fixed)	-40°C to +80°C
Rated Voltage	300/500 V	300/500 V	Up to 1100 V
Primary Strength	Extreme heat resistance	General-purpose flexibility	High core count + higher voltage
Typical Use	Furnaces, steel/glass plants, heating systems	Control panels, machinery, HVAC	Dense automation wiring, multi-circuit control

How to Choose the Right Cable for Your Application

• Is your cable routed near or through a high-temperature zone — a furnace, kiln, or heating system? Choose the HEAT 180, since standard PVC cables will degrade quickly in that environment.
• Is this standard indoor control panel or machinery wiring without extreme heat exposure? The CLASSIC 110 is a reliable, cost-effective default for this job.
• Do you need to run many control signals or circuits through one cable, or need a higher voltage rating? The CONTROL 110 with its 16-core configuration and 1100V rating is built for exactly that.

Where to Go Next

If you're also specifying single-core power cables for busbar or feeder connections inside the same panel, our ÖLFLEX® UNIPLUS single core cable guide covers that side of panel wiring.

Frequently Asked Questions (FAQ)

1. What is the main difference between ÖLFLEX® HEAT 180 and ÖLFLEX® CLASSIC 110?

ÖLFLEX® HEAT 180 uses silicone insulation and a glass fibre/steel braid sheath to withstand temperatures from -50°C to +180°C, while ÖLFLEX® CLASSIC 110 uses standard PVC insulation suited to general industrial environments up to +80°C.

2. When should I use ÖLFLEX® CONTROL 110 instead of CLASSIC 110?Choose CONTROL 110 when you need a higher core count for complex, multi-circuit wiring or require a higher voltage rating (up to 1100V) compared to CLASSIC 110's 300/500V rating.

3. Is ÖLFLEX® HEAT 180 suitable for control panel wiring?

ÖLFLEX® HEAT 180 is specifically designed for high-temperature environments like furnaces and heating systems rather than standard control panels, where CLASSIC 110 or CONTROL 110 would be more appropriate.

4. What does the core configuration (like 7G0.5 or 3G1) mean?

The number indicates the total core count, "G" denotes the inclusion of a green/yellow earth core, and the following number indicates the conductor cross-sectional area in sq.mm.

5. Are these cables flame retardant? Yes, all three cables — HEAT 180, CLASSIC 110, and CONTROL 110 — are flame retardant, an important safety feature for industrial and control panel wiring.

6. Can ÖLFLEX® CLASSIC 110 be used in outdoor applications?

ÖLFLEX® CLASSIC 110 has limited UV resistance and is preferred for indoor use; for outdoor exposure, a cable specifically rated for UV resistance should be considered.

7. What voltage rating does ÖLFLEX® CONTROL 110 support?

ÖLFLEX® CONTROL 110 16x0.75 is rated for up to 1100V, higher than the 300/500V rating of both HEAT 180 and CLASSIC 110.

8. Where can I buy genuine LAPP ÖLFLEX® control cables in India?

Why Cast Iron Motors Are Built for Tough Industrial Applications

Walk through any heavy industrial plant — a cement unit, a steel mill, a large pump house — and you'll notice the motors driving the critical equipment almost always share one thing: a solid, rugged cast iron body. That's not a coincidence or an aesthetic choice. It's a deliberate engineering decision, made because plastic or aluminum-bodied motors simply can't survive what these environments throw at them day after day.

This guide explains what actually makes cast iron motors different, why that construction matters so much in demanding applications, and walks through three real Innomotics cast iron motor models to show how the range scales across power ratings.

What Makes a Cast Iron Motor Different?

A cast iron motor uses a cast iron housing instead of the lighter aluminum or composite housings found on smaller general-purpose motors. This single design choice cascades into several real-world advantages:

• Superior mechanical strength — cast iron withstands heavy mechanical stress, vibration, and shock loading far better than lighter materials, which matters enormously in applications with constant vibration or heavy start/stop cycling.
• Better heat dissipation under sustained load — cast iron's thermal mass and conductivity help the motor manage heat more effectively during continuous, high-load operation, reducing the risk of thermal stress over long duty cycles.
• Long-term durability in harsh environments — the housing resists the wear, corrosion, and physical damage that dusty, humid, or chemically aggressive industrial environments inflict over years of continuous operation.
• Higher protection ratings — cast iron construction supports robust sealing, typically achieving IP55 protection as standard, keeping dust and moisture out of the internals even in demanding plant conditions.

Combine that housing with Class F insulation and IC411 self-cooling — standard across this motor family — and you get a motor built to run reliably at full load, in a hot, dusty plant, for years without the internals degrading.

Why This Construction Matters So Much for Tough Applications

It's tempting to think of housing material as a minor spec on a datasheet. In practice, it's often the deciding factor in whether a motor survives its application or fails early. Consider what these motors are actually asked to do:

• Continuous heavy-load operation — pumps, compressors, and conveyors that run for extended periods without rest, generating sustained heat that a lighter housing wouldn't dissipate as effectively
• Vibration and mechanical shock — crushers, mills, and reciprocating equipment where a fragile housing would crack or loosen internal components over time
• Dusty, humid, or chemically harsh environments — cement plants, steel mills, chemical processing units, and outdoor installations where IP55 protection genuinely earns its rating rather than just appearing on a spec sheet
• Long operational lifespans — industrial capital equipment is expected to run for a decade or more; a cast iron housing supports that expectation in a way lighter alternatives simply don't

This is exactly why cast iron motors remain the default choice across cement, steel, mining, chemical processing, and heavy manufacturing industries, even when lighter alternatives exist for less demanding applications.

Innomotics Cast Iron Motors — Three Ratings Across the Range

To see how this construction scales across power requirements, here's a look at three specific models from the Innomotics 1LE7 cast iron series:

1. Innomotics Cast Iron Motor — 15 kW / 20 HP, Frame 160L (1LE7501-1DC73-5AA4)

At the smaller end of this range, the 15 kW (20 HP) motor in a frame size 160L is suited to moderate industrial loads — smaller pumps, fans, and conveyor drives where reliable cast iron construction is still needed, but at a more compact frame footprint and power rating than the plant's larger machinery.

Best suited for: smaller pumps, fans, blowers, and general-purpose industrial drives where dependable, rugged construction matters but full plant-scale power isn't required.

2. Innomotics Cast Iron Motor — 200 kW / 270 HP, Frame 315L (1LE7501-3AC83-5AA4)

Stepping up significantly, this 200 kW (270 HP) motor in the larger frame size 315L is built for substantial industrial loads — large pumps, compressors, crushers, and heavy conveyor systems that demand serious continuous power alongside the durability the cast iron housing provides.

Best suited for: large pumps, compressors, and heavy-duty conveyor or crusher drives in plants where both high power output and long-term mechanical reliability are non-negotiable.

3. Innomotics Cast Iron Motor — 225 kW / 300 HP, Frame 315L (1LE7501-3AB73-5AA4)

At the top of this comparison, the 225 kW (300 HP) motor, also in frame size 315L, pushes further into heavy-industrial power territory. Sharing the same frame size as the 200 kW model but delivering more output, it's suited to the most demanding continuous-duty applications where maximum power density within that frame size is the priority.

Best suited for: the heaviest continuous-duty industrial applications — major pump stations, large compressors, and critical process drives where downtime simply isn't an option.

How to Choose the Right Power Rating for Your Application

• Calculate your actual load requirement — don't size a motor based on a rough estimate; use the driven equipment's actual power demand.
• Match frame size to your existing mounting and coupling arrangement, especially if you're replacing an existing motor.
• Leave a reasonable service factor margin rather than sizing right at the calculated minimum, particularly for applications with variable or peak loading.
• Confirm pole count and speed requirements match your driven equipment — cast iron motors in this series are available across multiple pole configurations for different speed needs.

Where Cast Iron Motors Typically Get Used

• Cement and steel plants — continuous heavy-load operation in dusty, high-temperature environments
• Chemical and process industries — reliable operation across demanding, sometimes corrosive conditions
• Water and wastewater treatment — large pumps requiring sustained, dependable power
• Mining and material handling — crushers, conveyors, and mills facing constant vibration and mechanical stress
• General heavy manufacturing — any application where long-term reliability under continuous load matters more than minimizing weight or cost
