Components

End Carriage — L-Block

Q: What capacity range do you manufacture in end carriages?

We build L-Block end carriages for crane duties up to 50 Ton, machined to your wheel base, rail gauge and rail section. Every unit is designed to IS:3177 / IS:4137 and FEM 1.001 duty classifications, and custom capacities are engineered on request.

Q: What's the benefit of the L-Block design?

The machined block wheel housing allows a wheel change in under an hour without disturbing the axle alignment — minimising crane downtime.

Q: Will the end carriage match my existing bridge girder?

Yes, we manufacture to your girder end dimensions, wheel base and rail gauge — share your drawing and we'll confirm fitment before dispatch.

Q: Why choose an L-Block end carriage over an open type?

The L-block design carries the wheel in a bolted block that can be removed sideways, so a worn wheel is changed without dismantling the whole carriage or lifting the bridge — valuable on cranes that cannot afford long downtime.

Q: What wheel material and hardness do you supply?

Wheels are forged EN-8 or EN-9 steel with machined treads and induction-hardened running surfaces, mounted on sealed bearings in plummer blocks for long life under continuous duty.

Q: How do you ensure the carriage stays square on the rails?

Mating faces are machined and joints are jig-drilled so the wheel axes stay parallel within tolerance. Correct squareness is what stops crabbing, uneven flange wear and rail damage over the crane's life.

Q: Can you match an end carriage to a crane built by someone else?

Yes — we regularly supply replacements for other makes. Provide the wheel diameter, wheel base, rail size and capacity, and we build a carriage that bolts straight onto your existing girder.

Q: What buffers and travel drives are fitted?

Rubber, spring or hydraulic buffers are selected by travel speed and capacity, with geared travel motors sized to your duty cycle and VFD-ready for soft start and stop.

L-Block end carriages with machined block-type wheel housings — the modern, maintenance-friendly standard where wheel assemblies swap out in under an hour. Supplied in pairs with LT drives, buffers and rail sweeps.

About This Product

Engineered For Indian Industry

End carriages carry the whole crane — and its load — on four wheels, so wheel quality and alignment decide how long your rails last. L-Block housings hold each wheel-bearing assembly in a machined block bolted to the carriage: when a wheel wears, you unbolt the block, slide in a spare and run again within the hour — no girder jacking, no hot works.

ETC machines mating faces and jig-drills bolt patterns so girder-to-carriage joints assemble square every time. Wheels are forged EN-8/EN-9 with hardened treads gauged to your rail size, and every carriage ships with rail sweeps, antidrop plates and buffers fitted.
