    Abstract: A lifting device for manipulating a track element at a manipulating location at least partially above a track transported to a manipulating location on a transport platform of a transport vehicle and includes a lifting device frame provided with power and drive system. Lifting elements are supported by the lifting device frame, for lifting the track element and transfer elements for moving the lifting device frame. At least one pair of support members supports and manipulates the transfer elements. The support members are mounted on a common subframe and at least one brace element is provided for movably mounting the common subframe to the lifting device frame, to allow the subframe to tilt and rotate with respect to the lifting device frame. Each of the support members has telescopic arms, movable between a retracted position in which the transfer elements are retractable upon the transport platform and an extended position in which the transfer elements are extended beyond the transport platform.
