The invention discloses a load-sensitive hydraulic generator system, a movable lifting working platform and a control system. The load-sensitive hydraulic generator system comprises a variable displacement piston pump for providing an oil source for a hydraulic generator and a hydraulic generator control valve bank, and the hydraulic generator control valve bank can adjust the rotating speed of a motor of the hydraulic generator and can feed back system load pressure to the variable displacement piston pump; the movable lifting working platform integrates the load-sensitive hydraulic generator system and the action control valve group, and the variable displacement piston pump can supply oil to the hydraulic generator or each linkage action module by controlling the on-off of the hydraulic generator control valve group or the action control valve group; the control system enables the movable lifting working platform to have an electric appliance anti-impact safety protection function, a hydraulic generator starting and whole vehicle action interlocking function and a hydraulic generator voltage stabilization control function. The problem that in the prior art, a vehicle-mounted hydraulic generator lacks starting protection and cannot provide stable voltage and frequency is solved.
