2.Check the oil quantity of each reducer. If it is lower than the specified oil level, it should be refueled in time. The oil quality must be clean. No corrosive agent or unclean oil should be mixed in. When filtering, apply filter to filter.

Oil for each reducer: hoisting mechanism reducer: 70# industrial gear oil rotary structure reducer: 90# gear oil traction mechanism reducer: 70# industrial gear oil

3.For the slewing mechanism, the large and small gear pairs and the rotary rolling bearing are coated with grease.

4.Check the power cable for damage, and loose or wear the joint to remove dust from the electrical equipment.

5.Check each safety device. If the work is out of order, it should be adjusted or repaired in time. In particular, the lifting torque should be limited to the weight limit and the reliability should be guaranteed.

6.Check the braking performance of the hoisting mechanism and the slewing mechanism. If it is not sensitive and reliable, it should be adjusted in time.

7.Check the contact and corrosion of the contacts of the controller and the contacts of the controller.

8.Check each joint bolt for any fall-off and tighten and add in time.

9.Check the lifting wire rope and the traction wire rope. If the number of broken strands exceeds 5% or the nominal diameter wear exceeds 5%, the wire rope should be updated. Check if the fixed end of the wire rope is firm, if the rope bolt is loose, and handle it in time.
