Abstract
A patient transfer trolley has a pivoted top mounted at the upper end of an hydraulic support column of adjustable height. Two hydraulic cylinders connected to one end of the table top are connected to respective hydraulic pumps mounted at opposite ends of the trolley base so that angle of the top can be altered and either end can be put into a Trendelenburg position. A third pump is connected to both the support column and the cylinders for adjusting the angle of the top. An overpressure valve diverts pressure from the third pump initially to the cylinders for adjusting the angle so that the top is returned to a horizontal position. The valve then opens to allow pressure to flow to the support column and raise the trolley top.
