1. Gear: They are innovated symmetrical arrayed highspeed synchronous gears, and are made from international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving.
2. Chain: Adopts high strong chain and high precision welding technology, meet ISO3077-1984 international standard; Fits for gusty overload work conditions; Takes your hands a better feeling; Multi-angle operation(with 45° ).
3. Hook: Made of high-class alloy steel, it has high strength and high security; By using newy desing, weight will never escape.
4. Limit Switch: Using limit switch component in designation to protect chain and ensure security.
5. Components: Main components are all made of high-class alloy steel, with high precision and security.
6. Framework: Slight design and more beautiful; With less weight and smaller work area.
7. Plastic Plating: By adopting advanced plastic plating technology inside and outside, it lookslike a new one after years of operation.
8. Encloser: Made of high-classed steel, more firmly and dexterous.
