The aerial ladder fire rescue fire truck is equipped with two sets of boarding control system ,one for turntable and one for working platform; the internationally advanced electro-hydraulic proportional control valve is used as the driving element; the computer display screen is set at the control position of turntable and working platform, which can directly display the luffing angle and arm length of boom; the proximity switch and signal light are also attached to display alarm, so as to realize the automatic reduction of limit position of each motion mechanism Speed and stop to ensure safe operation.
The working platform of the truck is equipped with a swing mechanism, so that the working platform can swing left and right, and it is easier to approach the building, which is convenient for saving people and materials. For the purpose of safety and reliability, the vehicle is also equipped with an emergency hydraulic pump. If the chassis engine fails, the gasoline engine emergency hydraulic pump can be started to retract the boom of the climbing vehicle back to the driving state, so that the fighters in the working platform can return to the ground safely.
