Abstract: A tilt control valve controls the flow of hydraulic oil to actuate the tilt cylinders of a forklift mast. The tilt control valve is switched between two positions by the forklift operator by means of a tilt lever. When at one position, the tilt control valve stops flow of oil to the tilt cylinders, thereby prohibiting tilting of the mast. When at the other position, the tilt control valve permits oil flow to the tilt cylinders, thereby allowing tilting of the mast. A control valve is located between the tilt cylinders and the tilt control valve. A seat switch detects whether or not the operator is sitting on the seat. A CPU permits the operator to continue to operate the tilt cylinders to tilt the mast when out of the seat for a brief period. However, after the brief period, the CPU closes the control valve to prevent movement of the mast unless the operator has returned to the seat.

Abstract: A lift truck pivot frame paper roll handling clamp assembly for engaging and moving paper rolls of varying diameter. The clamp has a mounting frame that is rotatably mounted on a lifting apparatus of the lift truck. A pair of sub-frames are pivotally attached to the mounting frame by four pivot arms which permit eccentrical pivoting of the sub-frame in relation to the mounting frame. This eccentric pivotal motion is essentially a guided linear side shift movement of one end of the sub-frame and guided a circular segment path at the other end thereof. This results in a turning generally about a "floating point" approximately halfway between the center of gravity of the roll and the body of the clamp. The clamp assembly also includes a pair of hydraulically actuated opposing clamp arms pivotally connected to the sub-frame for gripping paper rolls of varying diameter.
