1. Advanced overhead crane metal structure
Main beam is side rail box girder or shaped steel beam, end beam is welded by shaped steel or steel plate. Main girder and end girder connected with high strength bolts.
2. Crane trolley equipped with Demag electric hoist.
3. Crane traveling mechanism
Traveling mechanism adopts driven by respectively, include two solutions:
a. Motor with soft start feature, do not need to take the startup resistor and take other technical measures, direct transmission can get "soft start" effect, the motor itself with flat friction brakes, brake speed is adjustable. For the impact when the crane starts and stop has very significant improvement. Gear reducer system use closed hardened gear tooth, gear grinding with precision machining, smooth transmission, low noise, high load capacity, low temperature and long service life.
b. Using SEW or Flender "three-in-one" running drive, with superior performance and better effect.
