Group hanging rope hoist before using the test method

Group hanging   Rope hoist t generally used in large tanks, welding, building construction work climbing frame, is a low-speed electric chain hoist itself some characteristics improve the safety of use before using for the use of the environment and its group hanging  rope hoist Installation should be tested before use, following test method:
(1) isolated power supply, check all  hoist equipment  and electrical connections and connections are locked and is solid.
(2) Turn on the power using a lightweight load operating range of all group hanging  rope hoist and check operation is always smooth.
(3) Press the button switch does the "down" button, the operation of  rope hoist crane group decreased until the limit switches, at which point the motor will stop automatically.
(4) does the press switch is "on" button until the chain is completely retracted into the chain bag, and the motor stops.
(5) Check the group hanging hoist  load chain  lubrication (lifting chain lubricated at the factory had been oiled, but in the transport process may kill) any ready-made lubricant can be used to lubricate the lifting chain, We also recommend that you maintain a small amount of oil the chain bag, so that the chain can be immersed in the lubricating oil.
(6) When the host of the number of pairs of chain hanging chain or chain, is strictly prohibited under the hook from the chain will flip to avoid hazard.
(7) Check the destination group hanging  rope hoist chain direction, all welding points should be in the same direction, only the chain welded at all points on the same line when being determined to be fully operational.
