1. installation position turning axle on elevation mast, orientation rotation axle can carry out 360 ° of rotations around elevation mast; Cantilever one end, side is arranged on orientation rotation axle, and side cantilever is vertical with elevation mast; Pitching turning axle is arranged on the cantilever other end of side, pitching turning axle and orientation rotation axle orthogonal vertical; Upright arm is installed on pitching turning axle and carries out pitch rotation, upright arm and pitching rotational axis vertical; Upright arm top installation load platform, load platform is vertical with upright arm;
2., when elevation mast carrier changes, elevation mast run-off the straight, makes load platform run-off the straight thereupon; By luffing angle sensor measurement load platform inclination luffing angle;
3. orientation rotation axle drives side cantilever-rotating, rotates to the luffing angle maximum value position of measurement, i.e. pitching turning axle extreme lower position; The angle of inclination of load platform is the luffing angle of pitch reference measurement;
4. pitching turning axle drives upright arm to rotate according to angle of pitch angle value, and make upright arm and ground keep vertical, namely load platform keeps level with ground;
Complete elevation mast load levelling.
The luffing angle sensor of the method for the present invention 2. described in step is arranged in pitching turning axle, or is arranged on the cantilever of side, or is arranged on upright arm, or is arranged on load platform.
The method side of the present invention jib-length is 50mm to 2000mm.
The present invention's tool compared with background technology has the following advantages:
1, the present invention is by the side cantilever between orientation rotation axle and pitching turning axle, and the moment of being amplified load platform and the generation of load gravity by side cantilever carries out load platform leveling, and therefore leveling is accurately high, good stability.
2, it is simple that the levelling gear that the present invention makes has structure, is easy to realize, the advantages such as volume is little, lightweight.
3, the levelling gear stability of the present invention's making is strong, is easy to realize locking, when equal angle precision, can greatly reduces the advantages such as mast requirement of strength.
