Detailed Description
1. Lifting motor
Brand: China top brand motor from Nanjing, It is of the best quality motors, it has bigger torque, so it can be adapted to moving frequently, the Maximum torque is 2.4-3 times than the rated torque.
Lifting motor uses tapered rotor motor with strong staring torque to adapt frequent direct staring in the intermittent work.CD1 type hoist uses single speed motor and MD1 type hoist uses dual speed motor. The ratio of motor's constant speed and slow speed is 10:1
2. Speed reducer
The electric wire rope hoist use helical gear three stage reducer. Gear and shaft are made by alloy steel and high carbon steel and through proper heat treatment to ensure its reliability and service life. the reducer is independent, so its easy to load and unload it.
Box body and cover is made of cast iron to ensure hoist's good damping performance and reliable sealing.
3. Rope drum
Rope Drum is made of cast iron or seamless steel tube, using/with the help of spline transferring power. The sell of rope drum is welded with steel plate.
Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide 
proper support for the rope to minimize abrasive wear is provided. 
Drum Shaft resolves on Ball Bearings for ensuring smooth running.
Rope drum is the central heart of a hoist. The upper side is linked with traveling mechanism through equalizing beam. Both ends are connected with lifting brake and motor respectively.
The lower side works together with hook through wire rope. Up front of the cover, limiting stopper guide-rod and heavy punch stop block are installed.
4. 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. 
The rope guides of ours is thickened and dilated, so that it is not easy to be damaged.
5. Limit switch
Limit switch devices are fitted at both top & bottom ends, switch off power automatically to prevent load chain from running out.
6. Safety brake
The dual-disk electromagnetic brake features automatic brake in the event of a power failure. As best of free brake linings designed for approx.1million braking operations make for long maintenance intervals.
7. Traveling mechanism
Traveling mechanism is made of electric crab, traveling motor, traveling reducer, driven crab and so on. Main engine hangs under the traveling mechanism moving reciprocally. The normal traveling speed is 20 or 30m/min. If the lift capacity is 1~5t and the lift height is or more than 12m, another driven crab is installed.
8. Electric device
The electric device of CD1 MD1 model hoist consists of electric control box (No electric control box, if the lift capacity is 0.25t), button switch, Limiting stopper, connecting wires and so on.
For Control Box, It has device with up an down stroke protection of break off limiter and can cut off main circuit in an emergency, which ensures safe operation of electric block. Electric elements are of long service life and operational safety.
The normal operating voltage of button switch is 36V and 24V. Pressing the correct button can control the hoist through controlling on and off of the relay in the control box, according to the direction symbols on the button switch.
9. Steel wire rope
It uses GB1102-74(6*37+1) hoist steel wire rope which is durable in use.
Hoisting ropes comply with the exporting standards. The leading rope taken by the Drum does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six.
10. Lifting hook
Lifting hook is forged with specialized steel. In the use of trust ball bearing, lifting hook is linked with sheel through hook beam making lifting hook go slick. If lift capacity is five ton or less than five ton, slide wheel is single. If lift capacity is ten ton or more than ten ton, slide wheels are double.
The Hook Block is tested to 150 % of full load before assembly
11.Gear 
by adopting Japanese technology,they are innovated symmetrical arrayed high -speed synchronous gears, and are made from international standard gear steel.Compared with common gears, they are more wearable and steadier, and more labor saving.
Each Geared Shaft assembly is supported on ball or roller bearings, to ensure smooth, low-friction operation.
12. Gear box
It adopts casing of automotive technology
13. Trolley wheel
45 carbon steel, with frequency treatment, stronger and thicker.
14. Surface
Through special treatment and the surface is more bright and smooth.
