Movable bearing device for piping roof in construction building during scaffolding work, has lift protecting unit protecting device against lifting from rail profile and designed so that lift protection is ensured during shifting process

摘要

The device (10) has first and second set of rollers (12) rotatably supported between bearing plates (16, 18). A third set of rollers (14.1, 14.2) is spatially arranged in a transverse direction (Q) and perpendicular to a moving direction, and a roof beam profile (24) is movably supported in the transverse direction. A lift protecting unit protects the device against lifting from a rail profile (22) and protects the beam profile against lifting from the device, and is formed such that the lift protection of the construction is ensured during shifting process.
