Background As a special vehicle for manned aerial work, aerial work vehicles are increasingly replacing climbing work modes with extremely high risks in the past. With the development of urban construction, the overhead working truck is not only used for large-scale infrastructures such as wharfs, airports, water conservancy, power stations, gardens and the like, but also widely applied to urban facility installation and management such as street lamps, communication, traffic, advertising, photography and the like. Because of the limitation of the structure and the whole layout, the whole vehicle rollover stability of most overhead working vehicles at the maximum working amplitude is that the rear side of the vehicle body is square, and the maximum working amplitude required by different customers for vehicles of the same class is different in different working scenes and working conditions. The most common sectional amplitude devices in the market use rotary encoder devices, see fig. 5. The rotary encoder with the memory function has the following problems that 1. The rotary encoder with the memory function has high cost, and the rotary encoder needs to be matched with a turntable for rotation, so that the requirement on the processing precision of the turntable is high. 2. The rotary encoder records and converts the original angle and the current angle by relative rotation with the slewing bearing. The initial angle needs to be calibrated, after long-time rotation, the zero point needs to be recalibrated after long-time accumulation of errors due to errors of relative rotation ratios of the rotary encoder and the rotary support. With respect to the fixed type counterweight, the magnitude of the increase can be designed according to the weight of the counterweight only at the initial stage of design. The requirement of adding different counterweights and realizing different increases cannot be met.
