1.This machine suitable to work in the dock, warehouse, workshop etc Fixed working conditions, it can work within the 360 degrees to lift, move and materials handling.

2. This type machine is composed by the vertical shaft, revolivingarm, rotating shaft, hoist etc. The bottom of the vertical shaft is fixed on the concrete base. Horizontally Rotation of the revolivingarm: Manual, depend on the operator use the human force to push the impending working or self prepared rope etc device. The hoist travel with the right and left straight line on the H beam, use the hoist to lift the heavy materials. This type machine with advantages of the Simple structure, Operate convenience, Turning agile, wide working conditions.

3.Under the cantilever, it equipped with rack, hoist running dolly output gear and rack driven of occlusion, this could ensure the stability of the electric hoist. The hoist make shuttle running along the way of I-shaped beam, slewing of cantilever is finished by the motor to drive the reducer 

device. The cantilever is made of hollow steel structure, it is has a light weight, wide span, large lifting capacity, it is also more economic and 

durable. The jib crane which adopt special engineer plastic wheels with rotary bear could reduce the abrasion, running more smooth . It could 

install in any position with ranges of rotation 180°, 270°, 345°, 360°.
