1. Damaged water filled proof load testing bags

Recently, we got three 35ton WATER WEIGHTS water-filled proof load bags from our customer. Two of the proof load water bags were badly damaged. The damaged length is about 2~3m. The position is very special too. For this kind of damage, it is impossible to repair using glue or a hot-air gun. When most users encounter this level of damage, they simply abandon the fix. Direct disposal as scrapped.

2. Proof load testing bags were repaired

We carefully analyze the damage condition. A feasible repair plan was developed. It is safe and does not cost too much. First, pull out all the straps. Then clean up all the dirt on the water weights bags and some impurities that affect the high-frequency heating. Use hot air to dry the residual moisture in the water bag’s material. According to the size of the damage, cut out a repair piece of a suitable size. Finally, put the water bag on the machine and heat the repair sheet and the water bag. Compared with the production of new proof load bags, the repair work is more troublesome and more complicated.

The customer is very satisfied with the repaired water bag. After the load testing, these WATER WEIGHTS water-filled water bags were reused in a new crane load test project together with our water weight bags.
