Abstract
The invention has a deck that is supported by a first lever and a second lever. The first and second levers can be connected with a drag link. An actuator can be pivotally connected relative to but not directly to the deck. The location of the actuator relative an arm of the first lever is controlled with a control arm. A caster carriage and four idlers can also be provided. The idlers pivotally interconnect the first and second levers with the caster carriage. A radius arm can be connected to the caster carriage and to an arm of one of the levers. In this regard, the radius arm can be relatively long and can act in tandem with the respective lever and the idlers to minimize the horizontal shifting of the deck as the apparatus is raised and lowered.
