摘要： A control system for directing hydraulic fluid to selected cylinders on a lift truck to perform selective ones of a plurality of power truck functions, such as raising and lowering the lift forks on the truck mast, tilting the lift forks with respect to the truck mast, and extending the lift forks away from the truck mast, includes a control lever mounted on the truck control panel, having upper and lower control positions and a neutral position therebetween. A function control switch includes a manually actuatable switch button on the controlled lever. A counter means is responsive to the function control switch to cycle sequentially through a plurality of count states from an initial count state in response to actuation of the function control switch means. Means are provided responsive to the control lever and the counter means for supplying hydraulic fluid to selective ones of the cylinders under control of the control lever with selection of cylinders being determined by the count state of the counter means. The direction of flow of hydraulic fluid is determined by the position of the control lever.

摘要： In a material handling vehicle having an operator platform, a sideshift carriage mounted for lateral movement relative to the platform, a traverse carriage mounted for lateral movement relative to the sideshift carriage and forks mounted to the traverse carriage, an improved sideshift control system monitors the position of the sideshift carriage to define home positions for the sideshift carriage relative to the platform. Two home positions are defined, one for the forks facing to each side of the vehicle. The home positions offset the sideshift carriage to one or the other side of the platform to substantially center the load on the vehicle such that a portion of the base of the forks extends a set distance beyond one side of the platform, and the load supported on the forks extends approximately an equal distance beyond the opposite side of the platform. Two electrical switches are mounted approximately at the center of the platform opposite to the sideshift carriage and an activating plate includes two projections which operate alternate ones of the two switches dependent upon the direction the sideshift carriage is extended. A variety of actuating plates conveniently change the home positions and, hence, the preferred load carrying position of the forks for selected applications.

摘要： The lifting mast (20), frame (12), and outriggers (16) of a slip sheet lift truck (10) are fixed and immovable with respect to one another. The platen (30), push-pull mechanism (45), and back plate (31) are an integral unit mounted to permit side shifting on a tilt carriage (29), which is mounted on lower pivots (28) and tiltable thereabout with upper tilt cylinders (35). These are carried on a lifting carriage (25) which is vertically moveable and supported by a lifting cylinder (26) on the lifting mast (20). The lift truck outriggers (16) extend and slope forwardly and downwardly from the mast (20) to provide better truck stability, clearance for the platen (30), and good underclearance for ramps and dockboards.
