Chain hoists is to get straight to match the load lever principle of traction by means of human lever handle, a clamp body rotation acts on the movement of the load, drive the load line. It has a compact, light weight, small size, portable, safe, reliable, long life, small lever force of wire rope wear small advantages. It can be enhanced traction, down, calibration and other operations. If the configuration of a special device, not only can be used for non-linear traction hoists round job, and you can easily select the appropriate operating position, or with a smaller tonnage machines exponentially expand its load capacity, for large tonnage loads can using several machines operating in parallel. The main difference between an ordinary explosion-proof chain hoists and chain hoists chain hoists and general distinction proof hoists hoists proof that the material is aluminum bronze and beryllium as a rough chain hoists manufacturer, chain hoists shell is also used H62 copper alloy materials. The force of friction hoists sites include lifting hoists constitute wheels, siding, bracelets round, hook, gears, gear shafts are made of aluminum and beryllium bronze alloy material, the use of this material as a proof why hand Pull chain hoists hoist materials, mainly beryllium alloys, aluminum bronze alloy spark does not occur when the impact or friction, it is very suitable for the manufacture of flammable, explosive, under magnetic and erosive safe to use. Mainly alloy to withstand the impact of 561LJ 6.5-10% methane in oxygen or air containing 30% oxygen in the energy, magnetic shock 20, neither of sparks and burning. This is why the general proof hoists and chain hoists difference lies now. Shanghai Yan chain hoists, chain hoists, Shaanxi, Xinyu Xinyu lifting provided by Crane Co. Qingyuan.
