The lifting bridge is used to install and remove motor vehicle parts and is provided with a support frame (1), which has support straps (7) with support feet (5, 6), by which the support frame can be supported at the edges of an engine space opening (43) of the car body, at both ends of a telescopically extendable support rail (8, 18). The support frame is provided with two lifting devices (10), which are guided individually displaceably on the support frame (8, 18) and each has a lifting member (12), which can be raised and lowered by a rotating actuation and can be stopped in its position by automatic interlocking. The support frame (1) consists of two telescopically extendable support rails (8, 8', 18, 18'), which extend in parallel to and at laterally spaced locations from one another, and on which the lifting devices (10) are guided by means of guide tubes (11) in a positive-locking manner. The lifting devices (10) have a flexible pulling member (12) each, which is led through between the support rails (8, 8', 18, 18'), and which can be actuated by means of a worm gear mechanism (19) of the lifting device (10), which is self-locking in the direction of pull.
