When the equipment needs to be repaired, some end users only focus on the initial cost of this part. But they forget to consider the real cost of repair and service life. Undue downtime due to poor quality components or related components will increase the total cost of the equipment life cycle.

The following describes some of the daily maintenance of the crane. Seemingly trivial, time consuming, but very important. Remember the old saying: maintenance is not an expense, but profit!

7. All the wire rope has a series of similar broken performance, broken wire, deformation, corrosion, kink, fold, broken, etc., in this case the wire rope should be scrapped.

8. Worn or damaged wire ropes must be replaced only by products recommended by the equipment manufacturer.

9. When replacing the wire rope,Crane Sprares and Accessory the coil must be stopped to prevent the coil from unwinding or dragging too fast.
