The invention discloses a hydraulic supporting cat ladder, and belongs to the technical field of engineering vehicles. A main cat ladder assembly and a hydraulic cylinder are mounted eccentrically; one end of the main cat ladder assembly is fixedly arranged on a cat ladder mounting supporting base; the hydraulic cylinder is arranged on the hydraulic cylinder mounting base; the main cat ladder assembly is provided with a numerical-control detecting device; the numerical-control detecting device is provided with a detecting head; the ejection distance of a piston rod head of the hydraulic cylinder is maximum when a spreading cat ladder assembly is folded completely and is minimum when the spreading cat ladder assembly is unfolded completely; the piston rod head of the hydraulic cylinder is in contact with the detecting head no matter when the ejection distance of the piston rod head of the hydraulic cylinder is maximum or minimum; and starting and stopping of the hydraulic cylinder are controlled precisely by the numerical-control detecting device through the detecting head. The hydraulic supporting cat ladder has the advantages that the main cat ladder assembly and the spreading cat ladder assembly are driven to be folded and unfolded through the hydraulic cylinder, whether a hydraulic supporting cat ladder is folded or unfolded in place or not can be detected precisely through the numerical-control detecting device, starting and stopping of the hydraulic cylinder can be controlled accurately, operation efficiency is improved, and labor intensity of workers is reduced.
