Abstract: According to an example aspect of the present invention, there is provided a hauling beam, which can be placed in connection with, a load to be moved, so that by moving the hauling beam the load can be moved. The hauling beam can be moved, for example, by dragging. The hauling beam described herein makes it possible to lift the load to be transferred on the rollers, wheels or rolls and to transfer the load by means of them. The hauling bean further comprises a spring retainer having a body with at least one mounting block attached to at least one of the parallel slats, a slide mounted on the body and a spring retained between the slide and a detent on the body, wherein the slide is attached to the support beam, a chain running as a loop around chain sprockets at each end of the hauling beam, one end of the chain being connected to the slide and one end connected to the body of the spring retainer, and an actuator configured to move one of the sprockets in the longitudinal direction of the chain.

Abstract: According to an example aspect of the present invention, there is provided a hauling beam comprising at least two hauling beam modules, the modules comprising two nested beams, an outer beam and an inner beam, said nested beams configured to be movable longitudinally with respect to each other, wherein an inner beam of the first hauling beam module is connected to an inner beam of the second hauling beam module by a connector configured to transfer both forwards and backwards longitudinal movement of said inner beam of said first hauling module to the inner beam of said second hauling module.
