DIN and FEM dimensioned wear parts for cranes you did not buy from us
A crane out of service is a bay out of service. Sinomac supplies wheel blocks, end carriages, hooks, brakes, festoon and conductor systems to standard dimensions.
How It Works
Wear Parts Held to Standard Dimensions
Wheel blocks in types A, B, D, E and F with diameters from 80 mm to 500 mm, end carriages to DIN and FEM, forged hook blocks in 35CrMo and DIN 34CrMo4, buffers, brakes and rope drums. Because the dimensions are standard, they fit cranes Sinomac did not build.
Power Supply and Control Components
Conductor rail systems in copper to 5000 A and aluminium to 3000 A, mobile conductive busbar, C-track festoon systems, cable trolleys, energy chain, control panels and radio remote controls.
Why This Matters
A crane out of service is a bay out of service. Waiting for the original crane maker to quote a wheel block can keep a line down for weeks. Standard dimensioned parts shorten that to shipping time.
What to Send
A photo of the nameplate and the failed part, plus the wheel diameter or the rail profile. That is usually enough to identify a replacement without a site visit.

Frequently Asked Questions
Are your cranes built to FEM and DIN standards?
Yes. Sinomac designs to FEM, DIN and ISO. Duty group is set from your real lifting cycle, so the classification on the nameplate matches how the crane is actually used.
Can you supply a crane kit instead of a complete crane?
Yes. Sinomac supplies hoist, end carriages, drives, control system and anti-sway as a kit, and provides free production drawings of the girder for regional partners and clients buying kits, which lowers shipping cost.
How fast do you quote?
Sinomac provides a crane quotation within 24 hours and a CAD drawing within 48 hours.
What documentation ships with the crane?
Equipment qualification certificate, main parts qualification certificates, electrical drawing diagram, installation operation and maintenance manual, and installation and commissioning instructions.
Can we inspect before shipment?
Yes. Every hoist is pre-commissioned before packing and the crane is pre-assembled for a factory acceptance test. Clients are also welcome to appoint a third party inspection.
