Abstract

A lifting apparatus includes two parallel longitudinal members interconnected by at least one connecting element. A lifting beam is movable by a drive mechanism along the longitudinal members and supports, directly or indirectly, a handling device. Extending parallel to and supporting the lifting beam is a guide rail, which is received in spaced-apart carriages, for displacement in longitudinal direction in a freely running manner, as the lifting beam is moved by the drive mechanism. The carriages are arranged in a space between the longitudinal members and secured to the connecting element, wherein the longitudinal members and the lifting beam are formed with longitudinal grooves for engagement of sliding blocks so that the connecting element, the drive mechanism and the carrying unit are securable to the longitudinal members in any desired longitudinal position, and the guide rail is securable to the lifting beam in any desired longitudinal position.
