Safety measures must be taken at the construction site of the jib crane

When the jib crane is driving on a barrier-free line, the bottom of the hook or hanger and hanger must be more than 2 m above the ground. If it exceeds the obstacle, it must exceed the obstacle by 0.5 meters. For objects that are less than 50% of the rated weight, two objects are allowed to act simultaneously; objects that are suspended above 50% of the rated weight can only be operated by the tissue. A jib crane with a main hook and a secondary hook should not rise or fall at the same time. Do not apply welding or hammering on lifting objects and work under objects. If a power failure occurs on the door after a power failure, it must be inspected or repaired. If you need to work on site, you must have safety measures and special care.

Limit switches and interlock protectors should be checked regularly. Limit switches are not allowed as a parking method. Lifting and braking are not allowed when there is a problem with the lift brake. The suspended object must not exceed the personnel or equipment. No one can use the hook to transport people on the jib crane bridge. Each jib crane must have a nominal weight label in its place. It is not allowed to drive a jib crane after the certificate of operation and drinking. Inadequate attention, speech, smoking or irrelevant things are not allowed during the operation. Vehicles must be clean; equipment, tools, flammable, explosive, dangerous goods are not allowed.
