How to maintain multifunctional cranes in peacetime

What maintenance details should be paid attention to when using a multi-function crane? Next, let's talk about this problem!

The first is the wire rope part. Every week, check the winding situation of the wire rope on the reel. There should be no loosening, random winding, etc.; check whether the wire rope is broken, and if it is found, record the broken wire The number of wires. When there are or more than 11 broken wire ropes in a strand of wire rope, you need to replace them immediately; check the damage and corrosion degree of the outer layer of the wire rope, and the amount of damage and corrosion on the outer layer of the wire rope When it is greater than 309, it needs to be replaced with a new wire rope; check whether the wire rope is bent or deformed, and if it is, it needs to be replaced with a new one; then, it is necessary to check whether the insert device is secure.

The second is the hook of the multifunctional crane. Check every week for cracks; damage to dangerous sections (damage ≥ 10% of the original specification); opening layer degree (opening degree specification enhancement ≥ original specification 15%); the torsion deformation is ≥10; the dangerous section or the neck of the hook should not be plastically deformed; if the above conditions are achieved, a new hook needs to be replaced.

Then comes the electrical aspect. Every week, you need to check that the power cord and the control cable should not be damaged; check whether the grounding is good; whether the connection area of the electrical contact is loose or dropped, etc.; check the control Button, each function button can be used normally.
