The pole lift system comprises pole base, turning cylinder and pole, turning cylinder is installed on the pole base, be provided with rolling bearing outward, pole bottom hollow, be sleeved on the turning cylinder outside, be implemented in 360 ° of rotations on the turning cylinder by rolling bearing, pole is a く shape, and two ends and flex point place are equipped with fixed pulley.
Pole two arm subtended angles are 100 °～150 °.
Utilize the described bont of claim 1 to change the replacing method that tower crane promotes motor, it is characterized in that:
A, break down and to repair at the scene when needing to change motor, pole base, turning cylinder and pole are installed on the tower crane equilibrium arm when tower crane promotes motor;
B, the quadruplet fixed pulley is installed on tower cap root and pole;
C, at winch of floor mounted as its Power Drive Unit;
D, on pole, pulley and winch, put on steel rope;
E, with pole end wire rope rope on the hoisting ring of fault motor, hoisting cable gently;
F, rotation pole slowly put down the fault motor;
G, motor in working order is promoted on the equilibrium arm of tower crane with bont again, motor is installed.
Compared with prior art, the beneficial effect that tower crane replacing motor bont of the present invention and replacing method are had is: bont is simple in structure, tower crane promotes motor and changes easy construction, job safety is reliable, convenient disassembly, not limited by the place, be applicable to the camp site of various conditions.Compare with using car hosit, reduced to have reduced the use of oil plant, save cost, reduce resource because of using the car hosit engine exhaust emission to the pollution that air causes, energy-conserving and environment-protective, tower crane high benefit more is obvious more.
