The daily maintenance of the chain electric gourd
Please do not lift any items that exceed the rated load. The rated load is on the hook plate. No man is allowed on the lifting, and the electric gourd should not be used as the lifting mechanism for lifting people. No one is under the lifting object. Lifting objects and hooks can not be hoisted while rocking. Please move the gourd to the top of the object. The limiter is not allowed to be used repeatedly as a travel switch. Do not lift objects that are connected to the ground. Please don't overdo it. Do not pull other objects in front of the flashlight. Be sure to switch off the power supply before maintenance check. The maintenance inspection must be carried out in an empty space. Make sure the wedge is securely installed before using.

Not allowed to press two buttons that cause the electric gourd to move in the opposite direction. When you have finished work, you must turn off the power supply. The electric gourd should be operated by the special person, the operator should have full control of the safety operation discipline, strictly forbid the slanting. In use, special personnel must be inspected regularly by special personnel to detect the failure in time to take measures and carefully record them. When adjusting the sliding scale of the electric hoist, it is guaranteed that under the rated load, the brake slip will be less than or equal to V / 100 (V is the distance that the load will rise in the next minute). Safety precautions On the basis of understanding the instructions, note the following: Please remember the instructions and the nameplates before you do it. Please adjust the stop block of the upper and lower limit. Make sure your brakes are reliable before you use them. Do not operate if the wire rope is used before using the following abnormal condition. (1) bending, deformation, corrosion etc. The extent of the chain fracture exceeds the requirement and the amount of wear is large.
Loop chain electric gourd maintenance: First of all, the chain electric hoist gear box oil from began to operate up to 500 hours, please check the amount of lubricating oil is enough, regularly check the oil, the third month after the deficiencies need to refuel. Second, when using the chain electric gourd outside, it should be equipped with waterproof equipment. Third, always keep the parts of the ring chain electric gourd parts dry. When the operation is finished, please leave the gourd out of the moist area, the high temperature area or the chemical area to maintain its performance. Fourth, chain electric hoist chain maintenance, chain please on oil lubrication, high dust factory please on oil, and regularly remove the chain and ultimate guide of foreign body in the group, to ensure that the chain running smoothly.
