Electric crane trolley includes electric hoist trolley and electric winch trolley. And electric hoist trolley is divided into traditional electric hoist trolley and European type electric hoist trolley.
The electric crane trolley is composed of hoisting mechanism, trolley running mechanism and trolley frame, in addition to some safety protection devices.The lifting mechanism includes motors, brakes, reducers, drums and pulley blocks.
The motor drives the drum through a reducer, which causes the wire rope to wound up or down from the drum to lift heavy objects.
The crane trolley running mechanism includes electric motor, brake, reducer, wheel group, etc.The trolley frame is a frame for supporting and installing parts such as lifting mechanism and trolley running mechanism, usually welded structure.
European hoist trolley crane is one kind new developed crane which is accorded with the FEM/DIN standard.It includes the advantage such as the light dead weight, small wheel pressure, compact structure, low energy consumption and VFFD speed etc.
Compared with the traditional electric hoist trolley crane, the limit distance between well and hook is much smaller and lifting height is much higher so as to increase the working place of the existing warehouse.
Electric winch trolley working lever is higher than electric hoist trolley. Therefore, if the crane operates frequently and wants to have a long service life, you should choose the electric winch trolley crane. Without doubt, electric winch trolley crane is more expensive.
Traditional bridge cranes are usually composed of lifting trolley, bridge operating mechanism and bridge metal structure. The crane trolley is composed of hoisting mechanism, trolley running mechanism and trolley frame.
The crane cart is generally referred to as the crane of the bridge operating mechanism while the trolley is the running part of the lifting mechanism.The crane cart runs with the entire running on the track of the workshop, while the crane trolley runs on the main beam track.
