7. During operation, blind pressurization is prohibited, the lifting pressure should be controlled at about 300 Pa, and the rotational pressure should be controlled at about 100 Pa.
8. Always pay attention to whether the wire ropes are arranged in an orderly manner on the main winch.
9. Always pay attention to the working condition of the joint. If the wire rope is found to be twisted, the joint should be checked and replaced if necessary.
