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.
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° ).
Hook: Made of high-class alloy steel, it has high strength and high security; By using newy desing, weight will never escape.
Limit Switch: Using limit switch component in designation to protect chain and ensure security.
Components: Main components are all made of high-class alloy steel, with high precision and security.
Framework: Slight design and more beautiful; With less weight and smaller work area.
Plastic Plating: By adopting advanced plastic plating technology inside and outside, it lookslike a new one after years of operation.
Encloser: Made of high-classed steel, more firmly and dexterous.
