electric explosion-proof chain hoist – HHB

We offer various turn-key models with specifications designed to meet the user’s particular applications such as Hook suspension, Electric Trolley model, Low Headroom type and so on. ZR CRANE main products: Electric Chain Hoist range from 300kg to 50ton.


Details of Electric hoist:

  1. Electric motor partial outer cover

They are made of high strength aluminum system through compression casting formation.

Advantages: Solid structure and light weight/Fast release heat/Long service life/ Enclosed structure

Can be used in the chemical plants, electroplating factories, and various places.


  1. Side braking design

The masterly structure ensure the hoist absolutely safety when power is off in sudden. And ensures it is safe when overload. Also it combined  the motor braking  and the double brake system to strengthen security and durability.


  1. Gear

The gear made of alloy steel heat treated


  1. Anti-phase protector

Advantages: When power-supply wiring mistake, the control circuit is unable to move.


  1. Hooks

They are made by hot forging and heat treatment.


  1. Chain

It is made of FEC80 ultra strong heat treatment alloy steel.

Advantages: It is safely approximately when used in the rain water, the sea water, under the chemical and other bad conditions.

  1. ISO: M5 /FEM: 2AM

Insulation grade: F

  1. Protection class (hoist and push button): IP55
  2. Powder supply: 3 phase, 200-600v, 50 or 60 Hz
  3. Noise (single/ double speed): 81dB.




Explosion-proof chain electric hoist is a small capacity and low lifting height of the wire rope electric hoist the most ideal alternative products. Generally installed on the overhead beams orbit, or hanging on the fixed frame and special sling lifting goods and equipment necessary to wait, widely used in factories, mines, warehouse, wharf, construction sites, shopping malls, hotels and other industries, especially suitable for low places and such as dust, damp rot gas environment. BHH type explosion-proof chain electric hoist is a reference and absorb the designed structure of the advantages of similar products at home and abroad, it not only has many advantages of foreign products, but also has the maintenance convenient, practical and reliable, the price is low wait for an advantage, which is more suitable for the actual national conditions of our country.


Explosion-proof chain electric hoist advanced its three main component, the transmission, suspension, and the motor shaft to assemble the integration of advanced structure, this structure is not only easy maintenance, and good sealing effect, especially more suitable for outdoor and dusty places. The explosion-proof hoist adopts the new type of disc brake is the power of motor, the motor has the advantages of small volume and reliable braking, sensitive, intensity of wear resistant steel chain stability security improvements, its ideal for light lifting requirement.
