Manufacturing

A 80,000 m² crane factory under one roof

From raw steel plate to a tested, ready-to-ship crane — every stage of production happens in-house. That control is how we hold quality and deliver on time, order after order.

Capabilities

End-to-end in-house production

Controlling the whole process — not outsourcing it — is what keeps quality high and lead times short.

CNC cutting & profiling

Automated plasma and flame cutting for precise girder plates and structural members.

Crane box girders under fabrication with welders working along the line

Automated welding

Submerged-arc and robotic welding for consistent, high-strength box girders.

Machined rope drums with grooved barrels waiting on the shop floor

Girder machining

Large-bore boring mills for accurate rail seats and end-carriage machining.
