1. Introduction:
8 characteristics make HS-VT chain blocks high ability, security and agility, which greatly reduce your labor intensity.
1). Gear: they are innovated symmetrical arrayed high speed synchronous gears, and are made from international standard gear steel. Compared with common gears, they are more practical and steadier, and more laborsaving.
2). 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 degree).
3). Hook: made of high-class alloy steel, it has high strength and high security; by using new design, 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: sophisticated design and more beautiful; with less weight and smaller work area.
7). Plastic Plating: by adopting advanced plastic plating technology inside and outside, it looks like a new one after years of operation.
8). Encloser: made of high-classed steel, more firmly and dexterous
