Abstract: The invention provides a fluid control valve for controlling the flow of hydraulic fluid from a hydraulic pump to and from a plurality of hydraulic motors. The valve conveniently includes selector valve for selectively energizing a flow divider/combiner spool that controls the flow of hydraulic fluid to and from the motors. The flow divider/combiner spool has on its periphery lubrication grooves which also act as metering grooves. An advantage of the fluid control valve of the invention is that it regulates and equalises the flow and pressure of the hydraulic fluid delivered between a hydraulic pump and a plurality of hydraulic motors, thereby enabling each hydraulic motor to rotate in a synchronized fashion when traction control is required and without the operator having to deactivate the valve, the valve will disengage once traction to all wheels has been regained.

Abstract: A hoisting apparatus has a vertical supporting frame, a rearwardly extending base pivotally connected at the lower end of the frame and capable of closing on the frame, a foldable brace is attached at one end to the frame and at the other end to the base so as to lock the base into a supporting position and unlock the base to be pivoted to a closed position against the frame. A forwardly extending boom is pivotally mounted at the upper end portion of the frame. A first pulley is mounted on the upper end of the frame, and a first winding mechanism is attached to the rearward portion of the frame. A first cable passes from the first winding mechanism over the first pulley to the boom for raising and lowering the boom. A second pulley is mounted at the end of the boom. A second winding mechanism attached to the rearward portion of the frame, and a second cable passes from the second winding mechanism over the second pulley for attachment to a load.
