HS-VT series chain blocks 8 characteristics to make them have high ability and security,high agility, and this greatly reduced work intension.
     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.
