Tower Crane Knowledge sharing:

rief analysis of the repair, maintenance and testing of metal structural parts of tower crane

The repair and maintenance of metal structural parts of tower crane strictly follows the scrap standard of steel structural parts of crane. The metal fatigue strength, weld crack, structural deformation, damage and other conditions should be checked for the structure parts under the main stress.

The key welding seam of the structure parts under the main stress and the base material in the welding heat affected area should be checked. If any abnormality is found, it should be dealt with.
