1.Power source is three-phase alternating current,rated frequency is 50HZ,rated voltage is 380V,

2.The altitude height of site is ought to be less than 2000m,

3.Flammable explosive and corrosive gas are forbidden in the work environment,

4.The crane is forbid to lift molten metal,explosives,poison and corrosive,

1.Jib crane consists of arm made from rolled sections and are supported on anti friction bearing to ensure long troble free service.

2.The arm can swing 360C degrees, the arm is provided with end stoppers to limit the travel of trolley for lifting equipement,and supports the travelling cable system which supplies power to lifting equipment,.

1.It has two type jib crane,BZ model(light duty) and BZD modelo(heavy duty medium).

2.It can be used to match with single or double speed electric hoist and chain hoist.

3.It is suitable to wor in the dock,warehouse,workshop,etc,fixing working condition to lift move and material handling.

4.It is superior in the case of shout distance concentrated lifting,

5.It has characteristics of unique structure,safe and reliable operation,high efficiency,energy-saving and flexibility.

Construction is done in the following manner to reduce deflection

1.LUJC-I-heavy section I beam

2.LUJC-2 and LUJC-3-triangular turss constructions

This is done by chain located at the jib arm's end or manually by cranking with hands,In SMJC-3jib crane swiveling can be done by electical operation mechanism(on request).

If a full and positive 360C degree rotation is needed,then current collectors of pantograph type are provided theat are constructed using brass swing springs with insulation.
