Crane Load Testing Projects

Crane load testing is the an important test for crane safe operation. Crane test water bags for proof load testing is one simple, safety, and the cost-effective load test solution. The test weights can be slowly applied when filling water bags. So, the engineers can identify the structural issues. Then, correct these issues before the full test weight is reached. Prior to initial use, all new, extensively repaired and altered [...]
