The main difference between an ordinary explosion-proof chain hoists and chain hoists chain hoists and general distinction proof chain hoists chain hoists proof that the material is aluminum bronze and beryllium as a blank, Inner Mongolia chain hoists, chain hoists shell is also used H62 copper alloy material. Hoists constitute force friction parts include wheel lifting hoists, wall, bracelets wheel, hooks, gear, gear shaft is made of aluminum and beryllium bronze alloy material, high-quality chain hoists, why use This material is used as raw material proof chain hoists, chain hoists wholesale, mainly beryllium alloys, aluminum bronze alloy spark does not occur on impact or friction, therefore very suitable for the manufacture of flammable, explosive, magnetic and corrosion Under the safe use of the occasion. Mainly alloy to withstand impact 561LJ 6.5-10% methane in oxygen or air containing 30% of oxygen can impact 20 magnetic, chain hoists manufacturers, neither of sparks and burning. This is why the explosion-proof chain hoists and chain hoists general what distinguishes it. HSC chain hoists incorporates simple, efficient, economical design. The compact design, low headroom, high quality steel enclosure makes HSC chain hoist, even in a small space can easily install, operate. HSC chain hoists Features: 1, double pawl braking system and greater flexibility of the pawl spring to make products of high braking stability 2, double guide wheel structure makes lifting wheel more stable, effectively prevent card chain 3 , chain sprocket cover using folding design, even if the oblique sprocket can maintain smooth running smoothly 4, lighter weight, easy to carry 5, high mechanical efficiency, small hand zipper pull Qingyuan Xinyu Hoisting Machinery Manufacturing Co. for your dedicated service, welcomed the order.
