This type of crane has features of small weight and bigger lift capacity and better structure. 

Model CD1 Electric Hoist has only one normal speed, which can satisfy normal application. Model MD1 Electric Hoist provides two speeds: normal speed and low speed. At a low speed, it can do precise loading and unloading, mounding of sand box,maintenance of machine tools, etc. Thus, model MD1 Electric Hoist is more widely than Model CD1.

To meet the needs of lifting heavier cargo,our factory also manufactures HC type large tonnage electric hoist.

CD, MD series Electric hoist is a kind of light-small lifting equipment with advantages of tight structure light, small volume, wide common use and convenient operation etc. If reducer with hard gear surface are applied, it will have long lift and high mechanical efficiency, conic rotor brake motors are equipped which has safety limiter in both up and down directions.

MD type electric hoists have fast and slow lifting speed which makes it lift steadily and accurately.

Electric wire rope hoist is assembled from different independent units via hoisting gear box, hoisting motor with brake, rope 

drum, electric control panel and traveling trolley. All these units are separately accessible and promptly disassembled cost and 

downtime.

Motor: 

Hoist motor is a taper type rotor motor with braking, it is made by Nanjing Special Motor Factory, it is the best quality motors, 

it has bigger torque, so it can be adapted to moving frequently, the Maximum torque is 2.4-3times than the rated torque.

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.

Wire rope: 

Hoisting rope complies with the exporting standards. The leading rope taken by the Drum does not lip sideways when slack. 

The factor of safety, on the nominal breaking strength of the rope is six.

Rope Drum: 

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 Bearing for ensuring smooth running.

Electric apparatus controlling system: 

CD and MD model is composed of the contactor box, controlling switch, cut-off limiter. The working voltage of controlling 

switch is 380V, 36V or 24V (safety voltage).

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 our company is thickened and dilated, so that it is not easy to be 

damaged.

Hook: 

The hook block is tested to 150% of full load before assembly. The rope sheaves are fully guarded with protective steel casting. 

All sheaves rotate on ball bearing. The pulley is thickened and dilated than domestic common pulley.

In the meanwhile, our company could produce other kinds of electric wire rope hoists, such as the capacity is 16tons, 20tons, 

the lifting height is available from 30meters to 100meters more, single drum and hook pulley modify double drum and double 

hook pulley. Even the motor voltage may be modified according the client's requirement.

During the use of explosion-proof electric hoist in industrial hoist, when the surrounding environment produces explosive mixture mixed with combustible gas, dust and air, explosion-proof is a very important preventive measure to ensure personal safety and the safety of various production, storage and transportation systems.

Explosion-proof wire rope: aluminum bronze and beryllium bronze are used as blanks, and the shell of chain block is made of H62 copper alloy. Explosion-proof wire rope is applicable to flammable and explosive occasions, such as chemical, marine and other operations.

The rotating gear of the explosion-proof electric hoist is subject to high temperature heat treatment to achieve high wear resistance of the gear. Explosion-proof electric hoist has small pulling force, light weight, easy to carry, beautiful appearance, small size and durability.
