12-2-1 Inspection of steel structure bearing weight

Steel structures bearing weight such as boom, turntable, frame, outrigger, rim, etc must be checked at
least once every year. The welding line even not bearing heavy weight also should be paid special attention
during inspection.
If the crane bears overload external force, such as abnormal vibration and impact in operation process,
the dynamic load at parts bearing shock or impact should immediately be inspected. If any crack is fount
on the steel structure, the crack damage degree must be determined by professional and technical personnel
through the material analysis, such as magnetic particle testing, ultrasonic testing or X ray detection,
then repair welding or other methods to repair to damaged parts are implemented by the professional and
technical personnel.
Crane inspection personnel have an unshirkable responsibility for crane internal and external
inspection.
