Maintenance

(1) spreader during use, such as the emergence spin lock rotation is not flexible or not in place, you should check and adjust the adjusting nut, and then check the following parts: ① pawl tension spring is damaged, such damage should be replaced; ② whether there catching transmission mechanism, such as catching, is poor lubrication, you should drive the activities of the junction filling oil (or grease). In the case of the guide pin too tight, should be appropriately adjusting nut. In the case of loose connections, transmission pipes or other rod deformation should be corrected; ③ whether the amount of buffer spring tension is too small, if too small, you should shorten the length of rope connected to the buffer spring. (2) should be used to prevent the spreader instruction marks the dashboard paint off. Once found, the need for timely identification of paint complement the original instructions. (3) for lifting the rope, to be timely cleaned and coated with oil or grease, electrics tacker wire bend. (4) For the main force component, rings, spin locks, lug plate and rigging shackle clearance in normal use conditions, at least once every three months checks, without cracks and serious distortion. (5) All oil cup, oil cup including a ratchet mechanism, sliding seat bearing oil cup and spin lock box oil cup, the main activity should be based on the use of junction timely filling oil. (6) Always check Shengka is loose, the buffer spring is overstretched, identify problems and timely treatment. (7) Each spreader shall not exceed the rated capacity, buffer spring nor overstretched. (8) lifting the lifting process should be smooth to avoid lifting equipment and cranes or other occurrence mutual impact and deformation.
