+ For fixed objects in surrounding space (such as walls, column): 70 cm;

+ For transmission lines: As regulated in QCVN 01:2020/BCT.

- To examine, calculate KNCL and stabilize of the lift equipment with wind load at the equipment installation area.

- Do not change the structure or repair any part of the lifting equipment without approval and supervision by the competent person; The changes must be tested or inspected for safety as prescribed (for machine, equipment and materials with strict requirements on occupational safety and health).
