It plays an important role in fire protection, dealing with an emergency, construction, installation, maintenance and so on. Aiming at the GKZ14 high-altitude working machine of XhZhou HaiLun machinery Group, It does a lot of theoretical research and experiment test.This design is carries on the design and the research to this vehicleimportant constituent - hydraulic system and the electricitycontrol system, its hydraulic system by boards the hydraulic systemand alights the hydraulic system to be composed. Two between (verticalfluctuation type upper air vehicle is an exception) by the centerswivel joint connection, boards the hydraulic system by the amplitudesystem, the expansion and contraction system and the rotary systemthree basic systems is composed. In the entire hydraulic systemdesign, used the brake control to overcome in the oil motor existenceto release but the by-pass valve not to be able to lock in stops inthe airborne heavy item, caused the heavy item reliably to stop inairborne. The brake uses outside the constant pressure to control, mayfurther reduce the by-pass valve to open the pressure, enhances thereturn route efficiency.From the security, the reliable angle looked that, the upper airvehicle is different with the general project machinery, it scharacte ristic is the work frequency is not high, load smaller, butthe request security, the reliability is higher. Therefore, the upperair vehicle should have the urgent stop device. The upper air vehiclesupposes the spacing installment in each implementing agency movementend position, regarding folds the arm type and the mix arm -like upperair vehicle in particular should suppose the arm spacing installment,guarantees the entire vehicle the stability. The upper air vehicleamplitude system and the expansion and contraction system speed mustperform to control, prevents the production overspeed thephenomenon.Therefore, for guaranteed work high above the ground vehicle workstable, reliable, safe, work nimble, the efficiency is high, designs the fine hydraulic system and the electricity control system appears especially importantly.Keywords: The high-altitude working machine; braker, iternal leakage;external control with constant voltage;The installment limits the position.
