Precautions for daily maintenance of steel plate fixture and ingot sling
(1) if the swivel lock rotates inflexibly or is not in place during the use of the sling, check and adjust the adjusting nut, and then check the following parts:
① whether the tension spring of the pawl is damaged, if damaged, it should be replaced
② check whether the transmission mechanism is stuck. If it is stuck and belongs to poor lubrication, fill lubricating oil (or grease) at the movable connection of the transmission mechanism. If the guide pin is too tight, loosen the nut appropriately. If the connection is loose or the transmission pipe or other rod is deformed, it should be corrected
③ whether the tension of the buffer spring is too small. If it is too small, the length of the steel wire rope connected with the buffer spring should be shortened
(2) we need to measure the unknown signal. In use, we should prevent the indicator paint on the spreader indicator board from falling off. Once found, it is necessary to timely supplement the coating of the original instruction mark
(3) for the steel wire rope on the sling, it should be timely cleaned and coated with lubricating oil or the action grease passing through the relay, clutch and contactor, especially the bending part of the steel wire rope
(4) under the normal use and cleaning condition, the main stressed members, lifting rings, spinlocks, ear plates and rigging shackles should be inspected at least once every 3 months, and there should be no cracks and serious deformation
(5) all oil cups, including the oil cup of ratchet mechanism, the oil cup on sliding bearing seat and the oil cup of spin lock box, should be filled with lubricating oil at the main movable joints according to the use situation
(6) regularly check whether the rope clamp is loose and whether the buffer spring is excessively stretched, and deal with problems in time if found
(7) each sling shall not exceed the rated lifting capacity, and the buffer spring shall not be overstretched
color matching
(8) during the lifting process, the lifting should be stable recently to avoid deformation due to the collision between the lifting appliance and the crane or other equipment
