Workplatform

A workplatform (10) for providing access beneath deck level (30) has a support structure comprising a first arm (16) capable of rotation by motor (18) about a vertical axis and is suspended at an adjustable height (60) beneath the deck level (30) with a second arm (14) pivotably mounted on the end of the first arm (16) and supporting the workplatform (10). As shown the first arm (16) is formed of several telescopic sections and is secured to the lower end of a telescopic support column (19) which is rotatable by allowing ring and motor (24) about a vertical axis. The first arm (16) can be pivotably secured to the support column (19) and if the workplatform (10) is to be stored above deck level (30), then a retraction mechanism (40) is provided. The workplatform (10) has the degrees of freedom illustrated by the phantom lines and by the arrows designated 20, 52, 60, 62 and 64.
