The sectional hydraulic valve comprises an inlet cover, a plurality of hydraulic sections and an end cap. The hydraulic sections each having a pump gallery, a tank gallery, an A port, a B port, a spool and a remote pilot gallery. The end cap comprises a pump port coupled to the pump gallery, a tank port coupled to the tank gallery and a connecting conduit between the pump port and the tank port. The end cap further comprises a remote pilot gallery port coupled to the remote pilot gallery, a fluid passageway between the remote pilot gallery port and the connecting conduit, and a valve assembly operable to selectively permit or restrict flow of hydraulic fluid between the connecting conduit in the end cap and the remote pilot gallery in the hydraulic section.
A sectional hydraulic valve of the type comprising an inlet cover, a plurality of hydraulic sections and an end cap;
A truck mounted forklift for mounting on the rear of a vehicle, the truck mounted forklift comprising a u-shaped chassis having a pair of forwardly projecting side bars bridged by a rear crossbar, a wheel adjacent the forwardmost end of each of the side bars and a rear wheel mounted on the rear cross bar, a driver's station mounted to one side of the chassis, a motive power unit mounted on the other side of the chassis and a lifting assembly mounted on the chassis, the lifting assembly being operated by a plurality of hydraulic cylinders, a primary control panel for the hydraulics located internal the driver's station and a secondary control panel for control of the hydraulics located remotely from the primary control panel of the forklift truck, the secondary hydraulics control panel being positioned in a location accessible by a forklift operator in a position dismounted from the forklift, and in which the hydraulic fluid to and from the plurality of hydraulic cylinders is routed through the sectional hydraulic valve as claimed in any preceding claim.
