Specific configuration of aerial work vehicle: Hydraulic 360 ° full rotation, three folding arms, single hydraulic lifting cylinder, with bidirectional balance valve. Electrically operated boom. With 1 ton retractable hook, four hydraulic cylinders, adjustable legs, with two-way hydraulic lock (outrigger operation is manual operation, can be controlled separately.) With 1 ton retractable hook and warning lights on the left and right. "Stop at any time" sign on the tail. Paint: Engineering yellow, with reflective strip.

Structural advantages:

1. The subframe subframe is the foundation part of aerial work vehicle, which is fixed on the vehicle girder. There is a horizontal telescopic stabilizer at the rear of the auxiliary underframe, a vertical telescopic outrigger at the front, rear, left and right respectively, the middle turning head is installed in the middle, and the outrigger control valve is installed in the slewing bearing and left front part. When working at high altitude, the auxiliary underframe plays the role of balancing, stabilizing and connecting the upper and lower vehicles.

2. Working arm working arm is composed of upper folding arm, main arm and balance mechanism. When working, the angle between main boom and horizontal large angle is 70 ° and that between upper folding arm and main boom is 140 °. The balance mechanism plays a balance role in driving the arm and the working platform.

3. The middle rotary joint is a kind of hydraulic component, that is, the pressure oil discharged from the oil pump is delivered from the fixed part of the vehicle to the moving part of the upper carriage. The rotary core of the joint is fixed on the underframe, and the outer cylinder of the joint body is connected with the rotary table. There are three pipes in the middle of the rotary joint, three oil inlets and three oil outlets. The oil passages are separated by sealing rings.

4. Outrigger bi-directional hydraulic lock outrigger lock is the protection device of outrigger oil cylinder. Its function is to ensure that the outrigger will not contract automatically after it is lowered; to prevent "soft leg" caused by leakage fault of hydraulic or pneumatic pipeline during outrigger operation, which will cause serious accident.
