The invention discloses an engineering machine. The engineering machine comprises a body and a plurality of vertical support legs used for supporting the body on the ground; each vertical support legcomprises an extension sleeve and an oil cylinder, wherein each extension sleeve is arranged in the vertical direction, and comprises a first tube and a second tube; each second tube is arranged in the corresponding first tube in a sleeved manner, and can slide relative to the corresponding first tube; one of each first tube and the corresponding second tube is used for being connected with the body, and the other of each first tube and the corresponding second tube is used for being supported on the ground; each oil cylinder is arranged in the corresponding extension sleeve, and comprises a cylinder tube and a piston rod; and the two ends of each oil cylinder are correspondingly connected with the two ends of the corresponding extension sleeve so as to drive the second tube to stretch outand draw back relative to
