double girder trolley electric hoist
1. Advantage of double girder trolley electric hoist
The advantage of the double girder trolley electric hoist is that the length is small and the electric motor is mounted on the electric hoist inside the drum.
The double girder trolley electric hoist has a compact structure. The electric hoist with the axis of the motor perpendicular to the axis of the drum adopts a worm gear. The disadvantages are: large length dimensions, large dimensions in width, coarse structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual controlled. The overflow regulating valve and the magnetic contact pressure gauge can accurately control the pressure. The electrical control department adopted low-voltage control and increased the security of the control system. There was no manufacturer to produce this type of structure.
