Abstract

A wedge type lifting device particularly suitable for insertion into a narrow gap to force two components apart, has a housing (2) containing a circular section bar (1) with a sharply pointed end which fits between two blocks (3) which can act as slides in the open end of the housing. When a screw through the outer end of the housing is turned, it pushes the pointed end between the blocks forcing them apart. The ends of the blocks are shaped to fit into a small gap between the components so that in turn it forces them apart. An alternative design using a single sliding jaw can be piston operated.
