A control system for a personnel carrier attached to a boom which is displaceable by pressure fluid. The control system comprises at least one hand operable controlled handle axially rotatable in a limited clockwise or counter-clockwise direction to cause the boom to be elevated or lowered, respectively. A control valve is associated with the control handle and has at least one adjustable pressure fluid control component therein to control the displacement of the boom. A movable linkage is secured at one end to the control handle and at an opposed end to the fluid control component whereby rotation of the control handle causes displacement of the control component to regulate the pressure fluid which in turn controls the displacement of the boom.

Control system for cage supported by articulated boom

A hospital bed of the type having a base frame and a displaceable frame supported above the base frame by adjustable leg supports whereby the adjustable frame may be displaced vertically above the base frame in parallel relation or at an angular position such as a trendelenburg position. The leg supports are connected in pair and spaced apart adjacent a respective end of the frames. An articulated panelized frame is supported above the displaceable frame and the panels are articulated by an actuating mechanism. A first drive is connected to the adjustable leg supports to cause the displaceable frame to be displaced above the base frame. A follower mechanism is connected to a lower end of the leg supports to maintain the displaceable frame in lateral relationship with the base frame when displaced relative thereto. A second drive is connected to the actuating mechanism of the panelized frame to selectively displace the angular position of the panels.
