Wire Rope Hoist Arm 360 Rotation Jib Crane 1ton 2ton
Jib crane is a kind of crane with light working intensity, which is mainly composed of column, slewing arm slewing drive device and electric hoist. Among them, the lower end of the column is fixed on the concrete foundation through the foot bolt, and the slewing arm is a hollow steel structure, which is driven by the cycloid reducer to drive its slewing. The electric hoist runs in a straight line left and right on the cantilevered I-beam and lifts heavy objects. The cantilever crane has the characteristics of light weight, large span, large lifting capacity, economy and durability.
In order to ensure the safe use of the jib crane, the operator must comply with the following safety regulations and precautions:
- In the pre-work period, check the brake, wire rope, hook and other safety devices to ensure that the equipment is in good condition.
- Confirm that no one is on the walkway or track before closing the power supply.
- When lifting heavy objects, re-lower them after lifting them 0.5 metres off the ground height to check whether the brake performance is reliable.
- The operator shall be licensed to work only after proper examination and field study.
- It is strictly prohibited to overload lifting and slanting and crooked lifting to avoid equipment damage or safety accidents.
- When using the mobile jib crane, the operator should stand in a safe position to ensure that the lifting is directed after the commanding officer has confirmed that the employee has hung up the hook and that the person is standing in a safe area.
1. Overload protection in the event of overload, the hoist unit switches off and only the lowering motion is possible
