Principle

The pressure of compressed air can be transformed into mechanical energy through pneumatic motor, thus the output torque will drive the planetary reducer. Then the pneumatic controller will control the rotation of slewing gear to lift the load.

Technical highlights of our products

• Cable Roller: reliable, durable, maintenance-free

• Bearings: thrust bearings adopt dual dust-proof ball bearing

• Cylinder and piston: the lubrication inside the cylinder and piston adopts imported Germany grease, when compressed air entered the cylinder, the repeat movement of pistons will become more light and smooth.

• Distributing Valve: accurately control the volume of air income and outcome to reach the function of floating and balancing.

• Control Handle: button-style handle can effectively and accurately control the speed and pace of ascending and descending.

• Air cut-off Protection: when the air source being suddenly cut off, the centrifugal brake will automatically lock the brake, to prevent the free fall of loads.

• Brake: the centrifugal brake system can effectively control the sudden fall, which will prevent the sudden ascend or descend of steel rope or hooks.

• Ball Screw: the piston pushes the ball screw rotating and take the cable roller working synchronously, which will take the steel rope and lift the loads.
