(57) A mobile lifting device for handling incapacitated, injured or infirm comprises a
column (15) mounted on a chassis supported by ground engaging wheels (w)incorporating
a chassis comprising: a box section member (14);a panel or panels (33,34) forming
a substantial part of at least one wall of the member, the or each panel being removable
to provide access to the interior of the member the, or each, panel when secured in
place serving as a stressable part of the member and contributing to the torsional
rigidity of the member; and a pair of legs (12,13) on which are mounted the ground
engaging wheels linked by the box section; the column being secured at its lower end
to, for load bearing support by,the box section member; and a crane arm (23)supported
by the column at or near the one end of the arm by the column and being adapted at
or near the other end to the one end to receive a carrier whereby the device supports
a load to be lifted. The use of a box section chassis enables heavy components of
the device to be housed at the lowest position in the device so providing for a low
centre of gravity while enabling the components to be readily accessed.
