Duren's Conventional Overhead Cranes (COCs) are designed and manufactured in accordance with the recommendations of NBR8400/FEM standards:
NBR 8400 for the structural bridge (main girders, end carriages, general structures);
FEM 9901 for the mechanisms.
The main girders of the bridge (COC) are made of laminated or welded "I" profiles.
The connection between the girders (end carriage/bridge) is made with bolted connections using a connecting plate, offering practicality and ease for both assembly and eventual maintenance, all within manufacturing tolerances and ensuring correct equipment operation.
Bridge translation is driven by geared motors coupled to the wheel blocks, featuring dual-speed drives. The crane wheels are mounted in the wheel blocks, allowing for their replacement without removing the bridge from the rail. The entire assembly is demountable, maximizing ease of maintenance. They can be supplied for applications in Supported Overhead Cranes (SOCs) or Suspended Overhead Cranes (SOHCs).
