Crane Load Testing Project

Recently, our team finished another 200t crane load testing projecting on a foggy day. This is the second time crane load testing for the small crane of TIE JIAN ZHUANG 01. We already tested the main crane several weeks ago. In this crane load testing projects, we used two 75ton and one 50ton water filled weights bags. This project is finished smoothly. Didn’t meet the problem like last 320ton load testing.
