ABSTRACT:
A restraining device for controlling the movement of a loaded strop 3 comprises a power-driven reel for the strop and an associated pair of toggle-controlled clamping jaws 14, 15 pivoted at 16 and 17 respectively. The jaws are cross-connected by a link 18 and are loaded into the operative position to grip the strop 3 by a spring 25. The controlling toggle comprises links 28 and 30 pivoted together at 31, the link 28 being pivoted to the jaw 15 at 29 and the link 30 being pivoted to a fixed point 32. The link 30 carries a pivoted hand-lever 35 for releasing the toggle and formed with a hook portion 42 which engages with a corresponding hook portion 44 on the link 28 to lock the toggle in the released position to free the strop. The lever 35 can be released either manually or automatically by the piston 37 of a pneumatic cylinder 38. When the lever is released, the toggle moves to the braced position where it assists the action of the spring 25 in holding the jaws together to grip the strop.
