The invention relates to a lifting device for raising, lowering and pulling loads. The lifting device includes a hand chain wheel which can be turned in both directions by a hand chain. The hand chain wheel is coupled to a load wheel, which moves a load chain and a load suspended thereon. The hand chain wheel is covered by a rotatably supported cover with chain guide openings. The cover is rotatably secured by a supporting metal sheet which is located on a side plate of the housing that accommodates the load chain wheel. A radially outwardly oriented guide disposed on the cover engages with a slide ring of the supporting metal sheet. The slide ring has a central recess for the cover. |
