The eight features of the VITAL chain block:1.Gear: they are innovated symmetrical arrayed highspeed synchronous gears, and are made from international standard gear steel. Comapared with common gears, they are more wearable and steadier, and more labor-saving.2.Chain: adopts high strong chain and high precision welding technology,meet ISO3077-1984 international standard for gusty over load work conditions, takes your hands a better feeling, multi-angle operation3.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 swith component in designation to protect chain and ensure security5.Components: main components are all made of high-class alloy steel, with high precision and security 6.Framework: slinght design and more beautiful, with less weight and smaller work area7.Plastic plating: by adopting advanced plastic plating technology inside and outside, it lookslike a new one after years of operaion8.Encloser: made of high-classed steel,more firmly and dexterous.
