Abstract: Disclosed are a follow-up steering control system for a multi-axle automobile crane and the multi-axle automobile crane. In a steering state of the multi-axle automobile crane, an output oil pressure of a first oil pressure output port is greater or less than that of a second oil pressure output port; a piston rod of a left-turning hydraulic cylinder is lengthened and a piston rod of a right-turning hydraulic cylinder is shortened, or the piston rod of the left-turning hydraulic cylinder is shortened and the piston rod of the right-turning hydraulic cylinder is lengthened; and a first knuckle arm and a second knuckle arm are driven to make a rear left steering wheel and a rear right steering wheel turn left or right.
