END-CARRIAGES FOR BRIDGE CRANES DONAH end-carriages are designed for handling operations on bridge crane rails: ► at single running speed from 3.2 to 25 m/min; ► at two running speeds, from 12.5/3.2 to 80/20 m/min; Operating on: ► single girder, with a capacity of up to 20,000 kg and gauge of up to 25 m; ► double girder, with a capacity of up to 40,000 kg and gauge of up to 27 m. Designed and built on the principle of modular components assembled together in relation to their specific use, they are equipped with drive units comprising "DGT" series wheel groups, which are combined with "DGP"...

COMPONENTS ON END-CARRIAGES FOR BRIDGE CRANES THE MAIN COMPONENTS ON END-CARRIAGES FOR BRIDGE CRANES ARE THE: END-CARRIAGE FRAMEWORK: The load-bearing structure is made from a rectangular tubular section. The bridge crane girders are fixed to the end-carriage structure using a system of high-resistance bolts and a pin centring system.
