Check the bolts of the reversing support: 1. Before each operation of the crane or at least once a week, visually check the bolts on the reversing support; 2. After the first 100 operating hours of the reversing support, check whether the bolts are loose. Check again after 300 working hours; check every 500 working hours in the future; shorten the checking distance under severe working conditions.
If the bolts are found to be loose during inspection, please stop the construction and contact the local after-sales service department immediately.
