Abstract of the Disclosure - A pantograph lifting ramp for motor vehicles includes a pair of wheel guides supported by at least two pairs of columns, which are pivoted at their lower ends to two base frames. The columns of at least one pair have their lower ends connected through a torsion bar consisting of connectable sections. The lifting ramp includes a safety valve to prevent uncontrolled descent in case of failure of the hydraulic fluid system, and another safety device to arrest lowering of the lifting ramp if a worker's foot is accidentally placed between the base frame and a column or wheel guide during lowering of the ramp.
