Product Description

Double Girder Crane Trolley Lifting Device



This type electric trolley hoist is part of double girder overhead crane, it is main lifting mechanism of the overhead crane.
It can running on the main girder, there is a winch or fixed electric hoist on it. 
This trolley hoist is used for crane maintenance or Crane DIY Production.

CD or MD model electric hoist can be widely used to hoist heavy objects, or installed on the straight or curve I-section steel beam of monorail overhead cranes. They can also be used together with Electric Hoist gantry cranes and jib cranes.
All the above has made the electric hoists common used in industrial and ore enterprises, railway, wharf and warehouses.
CD or MD model monorail wire rope electric hoist is a kind of light-duty lifting equipment with advantages of tight structure,light weight, small volume, wide common use and convenient operation etc.If reducers with hard gear surface are applied,it will have long life and high mechanical efficiency. 

CD model electric hoist has one lifting speed. MD model electric hoist has normal lifting speed and slow lifting speed which make it lift steadily and accurately.
 

Application places:
1.Extensively used in factories, workshops, warehouses and many other occasions to hoist materials directly,
2.Installed on the straight or curve I-steel beam of Single-girder Cranes to lift goods.
3.It can also be used together with Electric Hoist Double-beam, gantry crane and slewing cranes to hoist different items and so on.
 
High configuration:
Motor: Motors are equipped which has safety limiter in both up and down directions. And the motor is Conic rotor brake motor,
in order to adapt to the frequent direct start in the intermittent work.
Reducers: Its reducers with hard gear surface and adopt 3 level helical gears to slow down the speed, so it will have long life
and high mechanical efficiency.

Main electric parts: adopts top quality and famous brand: Siemens brand.
Gear Box: Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on
ball or roller bearings, to ensure smooth, low-friction operation.
Rope Guide: Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may
not uncoil even when the Hoist is in unloaded condition.
Hook: The hook is closed type with high safety; it wrought with special high quality steel.
Rope drum: It made of cast iron and seamless steel tube, its shell is welded with steel plate. The drum device is the central part of hoist.
