Double speed electric hoist is a small-sized lifting equipment, which is installed on the single girder, bridge cranes, gantry cranes, jib cranes for material handling. As one of the commonly used material handling equipment, the double speed electric hoist is usually used in factory, mining, railway, port, and storage, etc.

Electric wire rope hoist is a type of material handling equipment, installed on a single beam crane, linear curve strander beams or it can be used at the hoisting mechanism of double beam crane, gantry crane, linear crane for material handling by industrial and mining enterprises, railways, and warehouses, etc.
The lifting capacity of double speed electric wire rope hoist is 0,5 to 32 ton and the working class is M3 and M4.
Lifting capacity: 0.5-32t
Lifting height: 6-50m
Working class: M3 M4
The roller is made of high-quality seamless pipes and transmits power through splin. Roller The roller is made of high-quality seamless pipes and transmits power through spline. Its case is made of welded steel plate. This is the core part of the hoist.
The hook is forged and connected to the pulley assembly through thrust ball bearing, so the hook can rotate freely. Hooks no more than 5ton lifting capacity are of single-pulley style and above 10ton is double-pulley style.
Adopts high strength wire rope with tensile strength of 1770 Mpa,, good safety performance and long service life.
4. Rope guide
Standard rope guide is made of Q235b steel.
5. Hoisting motor
The hoisting motor with large tractive force is employed to comply with the frequent direct traveling during course of working discontinuously. CD1 model wire rope electric hoist is equipped with ZD style single speed motor.
The gear and axes are made of alloy steel or qualified carbon-steel. All reducers adopt 3-level bevel gear. Proper heat treatment is conducted to ensure their reliability and service life. Finally, the box-body and box-cover are made of cast-iron. Both are well shake-reducing and sealed tightly.
7. Electrical equipment
The electrical mechanism consists of electric control box, limiter, button switch, connecting wire etc. According to the marked direction on the button switch, press the button correctly and control the hoist through the on-and-off of the relay in the control box. The operating voltage is usually 36V.
8. Safety protection
8.1. The accurate gear drive limiter is used as upper and lower limit, which can reliably cut off power circuit if hook moves to the upper or lower limit so as to stop the motor.
8.2. Overload protector: the electric wire rope hoist is using electronic overload protector, so that the total lifting weight will not exceed the rated lifting weight; if the pulling force of steel rope is more than 105% of the rated capacity, the overload protector device would automatic cut off lifting loop.
8.3 Emergency stop protection，Over-heat protection of hoisting motor ，Over-current protection ，Phase protection ，Voltage lower protection
9. Control way
Pendent line control
1. 36V control voltage safety for human being.
2. Easy to control, no additional driver necessary, operate following the travelling of hoist
3. Connected with the electric trolley suspended under trolley
4. Protection class IP54 IP55
1. 24V control voltage safety for human being.
2. Remote distance: not less than 100 meters,
3. Easy to control, no additional driver necessary, to operate more freely on the ground
4. Tens of thousands of connection frequency points, non-interference with each other
5. Protection class IP54 IP55. Its case is made of welded steel plate. This is the core part of the hoist
