1, the Zhanqiao and the crane pipe connections should be equipped with the standard flange corresponding with the crane pipe, flange from rail surface height of 3.7 ~ 4 meters.

2, the assembly, reference shall be made to the working drawing, from basic rotary device to the vertical tubes, bottom-up sequentially arranged, finally installing balancer.

3, install the balancer, the oil arm up to about 60 °, the balance on both sides of the pin into the hook, and then the binaural balancer end of the draw rod alignment lifting rotary actuator enclosure of single ear, mount pin shaft, and then loaded onto a cotter pin.

4, adjust the balance of force, the oil is arranged in a horizontal state, unscrew the rear end cover of the balancer, visible adjusting screw. Such as crane tube have the freedom to decline, then using the socket wrench, tighten the screw, such as crane tube free rising trend, loosen the screw, until the crane loading arm at -5 ° ~ 60 ° range stops.

5, the installation should take necessary safety measures in the process

6) Use and maintain:

1, traction crane tube alignment, applied force uniform, avoid impact.

2, when the operation is completed, the crane tube back to Zhanqiao is fixed, in order to avoid accidents, and the loading arm to about 60 ° position, using balancer in the relaxed state.

7) Technical parameters:

1、Nominal diameter：DN100－150mm

2、Working range：Maximum turning radius：4600mm   Minimum turning radius：3000mm

3、Angular of long arm：upper 60℃，lower -15℃

4、Working pressure：0.4MPa

5、Material：carbon steel, stainless steel, Lining anti acid and so on.
