Electric chain hoist components
Shell	Made of light aluminum alloy, the cooling fin is specially designed to ensure quick heat dissipation with a rate of up to 40% and continuous service. The integral enclosed structure applies to chemical plants and electroplated factories.
Side magnetic braking device	The latest design of magnetic force generators allows instant brake as soon as the power is off.
Support frame	Consists of two sturdy steel plates.
Transformer	24V\/36V/48V used to prohibit unexpected accidents, for example, Electric leakage while raining.
Limit switch	To make the motor stop automatically, to protect the safety of the chain.
Chain	Chinese Chain Or Imported FEC80 ultra heat-treatable alloy aluminum, It can be used in poor environments such as rain, seawater, and chemicals.
Reverse protecting device	Special cable solution protects control wire system.
Hook	Hot forging with the perfect strength, hard to break. The lower hook is ensured by 360-degree rotation with a safety tongue piece.
Push-button	Waterproof, light, and durable.

The Electric Chain Hoist features a simple, efficient, and economical design. Its compact design, low headroom, and lightweight steel construction make this hoist easy to install and operate, even in confined spaces.

1. Chain: adopts high strength chain and high precision welding technology, meets ISO3077-1984 international standard; fits for gusty overload work conditions; takes your hands a better feeling;multi-angle operation(with 45°).
2. Hook: made of high-class alloy steel, it has high strength and high security; by using a new design, the weight will never escape.
3. Limit Switch: using limit switch component in designation to protect the chain and ensure security.
4. Components: main components are all made of high-class alloy steel, with high precision and security.
5. Framework: slight design and more beautiful; with less weight and smaller work area.
6. Plastic Plating: by adopting advanced plastic plating technology inside and outside, it looks like a new one after years of operation.
7. Encloser: made of high-classed steel, more firmly and dexterous.

Details of the product:
1. Electric motor partial outer cover
High strength aluminum shell through compression casting formation.
Features: Solid and light, Fast release heat, Continuous use, Enclosed structure. Can be used in chemical plants, electroplating factories, and other places.
2. Side magnetic braking device
This masterly structure ensures the hoist is safe when the power is off. And ensures it is safe when his excess load. Also, it combines the motor braking as the double brake system to strengthen security and durability.
3. Gear
The gear is made of alloy steel and through the heat treatment
4. Antiphase protector
Advantages: When power-supply wiring mistakes, 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.
Advantages: It is safe approximately when used in the rainwater, the seawater, under chemical and other bad conditions.
