The invention discloses a
parking brake valve group, a hydraulic
system, a control method and an electric skid
loader. An inlet P1 of the
parking brake valve group is communicated with an outlet of a working pump, and a working port Y is communicated with a working port of a
parking brake of a walking
motor speed reducer; a pressure reducing valve, a one-way valve, an energy accumulator, an electromagnetic
reversing valve and a
pressure sensor are arranged between the inlet P1 and the working port Y; the
pressure sensor collects the outlet pressure of the energy accumulator and transmits the outlet pressure to the controller; when the whole vehicle does not walk, the electromagnetic
reversing valve is kept at a
brake keeping position, and when the whole vehicle walks, the electromagnetic
reversing valve is kept at a
brake releasing position. According to the invention, the intermittent starting of the working motor is realized under the transition working condition of walking but not working, so that the
energy consumption of the
system is reduced; meanwhile, the working conditions of the whole
machine working motor and the walking motor are combined, automatic parking is achieved, the problems that a parking
braking system is high in
energy consumption and single in
control logic are solved, and safe, energy-saving and convenient parking braking control is achieved.
