Abstract:

After the 1800t/h bridgetype grab ship unloader of a project had been assembled; an out of tolerance problem of the trolley track was found.

The problem was introduced; and the reasons of the problem were analyzed. The defect was repaired; and some preventive measures were proposed, which provides

reference for manufacturing and installing of the subsequent products.

Key words: bridge-type grab ship unloader, trolley track, out of tolerance, install, repair
