Lightweight portable lifting frame for mobile medical applications

摘要

A lightweight portable lifting frame for use in the mobile medical services has a collapsible construction comprising an H=shaped trolley base (1) with roller castors (2) at each corner supporting a robust central column (6,7). The column (6,7) is formed from two lengths of square section hollow tube which slot together axially to form a continuous run securely anchored (4,5) to the base (1) at its lower end. An angled hoisting jib (10,15) carrying a crossbeam (not shown) at its extremity (16) for patient chair support travels the length of the column (6,7) on upper (12) and lower (12.1) roller assemblies under the control of a hand or electric non-overhauling winch (19.1) to p pulley (9) and tractive cable.
