A lifting device, in particular a lifting device for a roof box, for installation to e.g. a garage ceiling, comprising aframe (1) consisting of a central beam (4) and two side beams (5, 6) fixed across this, and a winding mechanism (3) with a drum (17) for winding up two continuous straps (18, 19). The straps (18, 19) are wound onto the same drum, thus ensuring synchronous winding. Each strap forms a loop (24) that may be passed underneath a roof box. |
