Dongqi 7.5 ton electric chain hoist is a small light lifting equipment. Electric chain hoist can be classified suspend hook type chain hoist, chain hoist with manual trolley, chain hoist with electric trolley, low headroom chain hoist.
7.5 Ton Electric Chain Hoist
Dongqi hoist convinces through the compact, elegant design, light weight, robust construction and technical innovation. Thus Dongqi electric chain hoist is highly efficient and engineered for a long working life.
1. Shell
It is made of light aluminum shell, light but hard. The cooling fin is specially designed to ensure quick heat dissipation with the rate up to 40% and continuous service.
The integral enclosed structure is applicable to place like chemical plant and electroplate factory.
2. Side magnetic braking device
The magnetic force generator is the latest design which is featured for generating magnetic force.
It allows instant brake as soon as the electric power is cut off. Thus the braking safety while loading is guaranteed.
3. Limit switch
The limit switch device is installed where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety.
4. Chain
The chain shall adopt the imported FEC80 ultra heat-treatable aluminum alloy chain.
It can be safely used in poor environments such as rain sea water and chemicals.
5. Hook
It is hot forging with perfect strength that is hard to break. The operation safety of the lower hook is ensured by its 360 degrees rotation and safety tongue piece.
6. Support frame
The loading support frame consists of two steel plates, which is extremely sturdy.
7. Transformer
24V/36V transformer device. The device is used to prohibit unexpected accidents caused by electric leakage and guarantees the safe uses while raining.
8. Electromagnetic contractor
Electromagnetic contractor can be used safely under high frequency.
9. Inverse phase sequence protecting device
It is the special electrical installation which controls the circuit not to work in case of wiring error in the power supply.
10. Push button
Waterproof push button is applied. It is light and durable.
Widely used to Lift, loading and unloading, repair equipment, hoisting goods, install on a suspended I-steel, curve track, jib crane rail and fixed lifting hoisting heavy weights.
