Overview of Winch Trolley Rotating crane with carrier-beam:
The crane is mainly used in steel plant such as cold rolling workshop, hot rolling workshop or coil, billets, rebar, flat steel storage and handling.
The winch trolley rotating overhead crane is designed with open winch type lifting mechanism, which has a higher working class up to M8 and more durable and strong. One special design is that its lifting trolley can rotate on the main bridge girders. The rotation design gives crane a more stable and easy convenient material such as long size rebar bundle, billet, pipes' handling operation. The upper position rotation design can reduce the load swing because of the double hoisting point.
We know that for steel mill working condition, it is continuous operation, which must need crane to be extremely durable, free maintenance and best quality. The main and most essential parts are the transmission mechanism which are consisting for motor, gear box and brakes.
We select crane motors and reducers from ABB, Siemens and SEW. The purchaser can anyway describe a special duty which is not standardized, according to the real duty of the motor. Where the purchaser does not declare a duty, we shall assume that duty type S1 (continuous running duty) applies. It is Continuous running duty. Once started, the motor works at a constant load at least until thermal equilibrium is reached. Then that motor may be operated for an unlimited period.link:http://www.chinacranemanufacturer.com/steel-mill-crane/steel-mill-overhead-crane/winch-trolley-rotating-overhead-crane-with.html
