NRK gourd gourd usage rules I. Preparations 1, select the appropriate tonnage crane hoists to be based on the weight of the device or the workpiece, or the workpiece to be hanging device shall not exceed the weight lifting hoists tonnage. 2, whether single, double lifting chain hoists HSZ type chain hoist, do not remove the lifting hooks to use. 3. Check the chain hoists from hook, lifting chain, brake and rotating parts are intact and reliable. 4. Check the sprocket chain hoists guard is intact, hand chain is intact. 5, based on the weight lifting objects reasonable choice lifting points, want to lifting points for reinforcement if necessary. 6. Select the appropriate helper other lifting equipment. Second, a lifting operation, the use must be intact chain from the hook, and the proper use, to be checked before lifting lifting weights is securely tied. 2, check before lifting hoists lifting chain twisting and knotting not appear the phenomenon began hook assemblies can not flip double chain, may not be used from lifting heavy hook hook tip. 3, when the first trial crane lifting operations HSZ type chain hoist prices, when the weight off the ground or floor to check if normal operation, reliable braking can continue lifting operations. 4, lifting lifting operations shall not stand on lifting objects were lifting operation, not in the heavy lifting left vacant job site. 5, the lifting process forbids any person to any part of the body extends into the bottom of lifting objects. 6, using oblique hanging chain hoists, to have more staff on-site command squad captain when hauling operations, and not for the heavy lifting off the ground or floor. 7 Never operate with a power other than human when lifting. 8. Do not overload use. 9. The process of lifting heavy objects found too much resistance should immediately stop using the following tests: (1) to be lifting the weights and other objects have no connection. (2) hoists the parts have not damaged. (3) to be lifting weights exceeds the rated load chain hoists. 10, chain hoists heavy lifting or decentralized distance shall not exceed the rated travel hoists. 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 the blank, chain hoists shell is made of a copper alloy material is H62. The force of friction hoists sites include lifting hoists constitute wheels, siding, bracelets round, hook, gears, gear shaft and are based on parameters HSZ type chain hoist aluminum bronze and beryllium copper alloy material, why using this material as a raw material proof chain hoists, mainly beryllium alloys, aluminum bronze alloy does not happen spark HSZ type chain hoist models at impact or friction, it is very suitable for the manufacture of flammable, explosive, magnetic as well as the safe use of corrosive applications. 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. HSZ type chain hoist models, HSZ type chain hoist, lifting from Qingyuan Xinyu Xinyu Hoisting Machinery Limited.
