Features of underhung overhead crane
Main beam: The main beam adopts box-type structure and connects with end beams by high-strength bolt ensuring easy transportation. The professional processing equipment ensure the connection accuracy of main beam and end beam, making crane run steadily.
End beam: End beams are the rectangular steel pipe and welding molding in a CNC machine tool positioning processing; each end beam is equipped with a double wheel rim wheel group, buffer and anti-derailment protection device.
Hoist:
- Maximum space using
- Precise operation
- Low maintenance cost
- Less fault downtime
- Minimum hook limit space & distance
- Standard world-renowned brands: SEW, ABM three in one type motor, Schneider electric parts
Drum, Steel wire rope, Rope guide:
- The drum is made from high-quality seamless pipes and processed by numeral control CNC machine, after finish machining, the rope groove on drum works coordinately with rope guide to efficiently prevent rope loose and tangling.
- Steel wire rope adopts high strength 2160N/mm2 imported wire rope, which has super safety performance and longer service life
- Standard rope guide is processed from engineering plastics, with strong abrasion resistance and good self-lubricating performance.
