Abstract
In modern engineering construction, automobile crane is widely used in lifting machinery.The hydraulic system determines the performance of the crane. A good hydraulic system can make the crane safer and more efficient.
In this paper, the operating conditions of the crane are described in detail, and the hydraulic system scheme is designed according to the operating conditions.According to the working requirements of the mechanism, the design parameters are determined, and the hydraulic system is calculated and the components are selected.The design of hydraulic pump station and oil tank was completed.
The control mode of the hydraulic system is improved based on the multi-way reversing valve.
Parallel control is adopted to ensure that the actuator can work simultaneously when necessary.
