Abstract
A load lifting device of the hoist type, comprises a flat strip 5 arranged to form two hoist runs on opposite sides of a connection member 6 for a load. The two runs of the strip 5 are simultaneously wound up on, or unrolled from, a single reel. A spacing roller 20 forms in the strip 5 a substantially horizontal upper run. This improves the stability of the load by spacing apart the upright runs 21, 22 of the hoist.
