PURPOSE: A balancing air hoist is provided to make it possible to accurately lift the load, operate with small power, and easily assemble. CONSTITUTION: A housing is formed of an outer housing(2) and an inner housing. A shaft(10) is installed at the inner center of the outer housing to penetrate the inner housing. A vane(35) generates power by a compressed air supplied from a manifold and an epicycloidal gear train(11) transfers the power of the vane to a reel drum. A drum device is rotated clockwise by the power transferred from the epicycloidal gear train to wind on/off a lifting(40) and a disc brake system controls the torque of the shaft. The vane, the epicycloidal gear train, the drum device, and the disc brake system are installed to the shaft. |
