The hydraulic system of the self-propelled aerial work platform usually consists of a travelling system, a swing system and a boom system.
The travelling system of aerial work platform can be divided into open loop system and closed loop system, for both systems Hengli has the corresponding mature solutions. Based on different customer requirements, Hengli is able to provide the most suitable solution. The open loop system adopts the HP5V series open loop pump, HVSP15 series electric proportional multi-way control vlave and HM3V series cartridge travelling motor while the closed loop system adopts the HP3G series closed loop pump and HM3V series cartridge travelling motor, which has a comparable lower power consumption, higher efficiency and contributes to the compacter structure of the hydraulic system.
The swing and boom systems of aerial work platform usually share the same pump and various actions are controlled by the HVSP15 series electric proportional load sensing multi-way valve, which has a high control precision, stable small flow output and good micro motion performance, making the boom control more stable and accurate.
