Abstract
At present, the hoisting mechanism of existing large-tonnage auto crane has mostly adopted open loop hydraulic system, for security reasons, the load loop tends to input larger load, causing unnecessary energy loss of engine. In order to solve this problem, adopt the closed type hydraulic system forth load loop, that is, carry on constant power control for load input power to ensure the constant control of optimal load rate of engine, achieve the safety and energy saving of the auto crane. According to the principle that the power of hydraulic system is equal to the product of pressure and flow in the system, as long as carrying on constant control for the pressure and flow in hydraulic system, the closed loop control of hydraulic system can be realized.
