Abstract (en)
[origin: EP2902860A1] The invention provides a leg control system, comprising a command transmitting unit, a leg controller and electromagnetic valves for controlling actions of legs, wherein the command transmitting unit is used for transmitting a leg control command; the leg controller simultaneously transmits an action instruction to the electromagnetic valves corresponding to a plurality of legs according to the received leg control command from the command transmitting unit; and the electromagnetic valves are reversed according to the control instruction so as to control the actions of the plurality of legs. Correspondingly, the invention further provides an engineering machine. According to the technical solutions of the invention, the plurality of legs can be controlled simultaneously, and problems of uneven stress and the like when a single leg is controlled are solved.
