Single Speed Electric Chain Block 220V 440V

♣1. PDH Electric Chain Block Introduction http://www.electric-block.com/products-a/7.html

1. Electric motor partial outer cover

They are made of high strength aluminum system through compression casting formation.
Features: Solid and light, Fast release heat, Continuous use, Enclosed structure. Can be used in the chemical plants, electroplating factories, and other places.

2. Side kind braking
This masterly structure ensure the hoist absolutly safty when the power off. And ensures it is safe when has excess load. Also it combine to the motor braking as the double brake system to strengthen security and durability.

3. Gear
The gear made of alloy steel and through the heat treatment

4. Antiphase protector
Advatages: When power-supply wiring mistake, the control circuit is unable to move.

5. Hooks
They are made by hot forging and heat treatment.

6. Chain
It is made of FEC80 ultra strong heat treatment alloy steel.
Advatages: It is safely approximately when used in the rain water, the sea water, under the chemical and other bad conditions.
