The working principle of aerial ladder truck is mainly based on hydraulic system. The hydraulic system realizes the ascending, descending and inclination adjustment of the lifting platform by utilizing the flow and pressure of the liquid. The hydraulic system is composed of hydraulic pump and hydraulic cylinder and control valve, etc. When the operator sends a command through the control system, the hydraulic pump draws fluid from the tank and transmits its pressure to the hydraulic cylinder. The hydraulic cylinder pushes or pulls the lifting platform to ascend or descend under the action of hydraulic pressure, and meanwhile, the flow and pressure of the liquid can be adjusted by adjusting the control valve, so that the stable movement of the lifting platform and the adjustment of the inclination angle are realized.
In addition to the hydraulic system, the aerial ladder truck is equipped with a support structure that provides additional support and stability to prevent the equipment from tipping or shaking while working at height, thus ensuring the safety of the operator. The stand is usually composed of multiple telescopic arms and support legs, which can be adjusted in length and angle as required to adapt to different working scenarios and terrain conditions.
Generally speaking, the working principle of aerial ladder truck is to provide stable working platform through the cooperation of hydraulic system and support structure, and realize accurate height and angle adjustment through control system, so that the operator can safely and efficiently carry out various tasks in the high altitude environment.
