Abstract: The present invention is a personal watercraft lift and transporting cart. In particular, the present invention is directed to a lift that can lift and rotate a personal watercraft (“PWC”) so that repairs can be conducted more ergonomically. The lift preferably has two lifting arms attached to upright frame members. In turn, the upright frame members extend vertically from a mounting base. The lift also preferably has two actuators pivotally attached to the lifting arms at one end and attached to the mounting base at the other end. When the actuators extend, the lifting arms lift and rotate. The transporting cart preferably has a cart chassis, a hull bunk and two receivers, where the first and second receiver are spaced to allow insertion of the first and second lifting arms so that the cart can be lifted and rotated by the lift with PWC mounted on the cart.

Abstract: An agricultural combine with draper header includes left and right conveyors, and a microprocessor-based controller coupled to the conveyors to determine whether one of the conveyors is overloaded or slipping.

Abstract: A pallet jack having first and second turn radii includes a support frame having a first end and a second end. The support frame is positionable between a raised position and a lowered position. A main wheel connects to the support frame proximate the first end while a first extensible wheel connects to the support frame proximate the second end. The distance between the main wheel and the extensible wheel define the first turn radius when the support frame is in the raised position. A ground engaging device attaches to the support frame between the main wheel and the first extensible wheel. Positioning the support frame towards the lowered position, the ground engageable device engages the ground and the extensible wheel disengages the ground. The second turn radius is thereby defined by the distance between the main wheel and the ground engaging device, which is less than the first turn radius.

Abstract: A load control system for a roll off trailer for effectively controlling the velocity of a load during unloading. The load control system for a roll off trailer includes a shaft, an actuator connected to the shaft, a plurality of levers pivotally attached to a roll off trailer, and a plurality of brake shoes attached to the plurality of levers. The plurality of brake shoes are aligned with corresponding rollers on the roll off trailer to selectively frictionally engage the rollers.

Abstract: A steering device for decreasing a turning radius of a pallet jack includes a ground engaging member connected to a support member of the pallet jack between a main wheel and an extensible wheel. The load supporting member of the pallet jack is positionable between a raised position and a lowered position. A first turning radius of the pallet jack is defined by the distance between the main wheel and the extensible wheel. While the extensible wheel engages the ground when the support frame is positioned towards the raised position, positioning the support member towards the lowered position engages the ground engageable member with the ground causing the extensible wheel to disengage the ground. The main wheel and the ground engageable member then define a second turning radius which is less than the first turning radius.

Abstract: An automated guided vehicle has plural conveyors for transferring materials to be transferred mounted on a self-propelling dolly and juxtaposed in a transverse direction. Each of the conveyors includes plural part conveyors whose operation can be controlled individually and arranged in tandem in a transferred direction. One or three or more part conveyors may be disposed or arranged in tandem in the direction of the vehicular width. One or three or more part conveyors may be disposed or juxtaposed in the transverse direction.

Abstract: A floor panel for a vehicle compartment includes a first surface and a second surface opposite the first surface. The first surface and the second surface have different material properties. One of the surfaces is provided with a plurality of rollers disposed to project above the surface when the surface is uppermost. Both of the first and said second surfaces are capable of being uppermost while the floor panel is located in the vehicle compartment.

Abstract: A roll-off trailer or truck bed for hauling cargo includes a cargo controlling mechanism that allows for the controllable removal of the cargo. The roll-off trailer characteristically includes a plurality of rotatable rollers disposed transverse to the longitudinal length of the trailer. The cargo controlling mechanism includes a brake mechanism preferably associated with at least several of the plurality of rollers. When actuated, the brake mechanism retards, stops, or nonrotatably restrains rotational movement of the rollers in order to slow down or stop the off-loading of the cargo. Actuation of the brake mechanisms may be accomplished through hydraulic, electric, pneumatic, mechanical, or other means. Each brake mechanism may be separately controlled by the operator in order to selectively retard the rotation of the desired roller. Alternatively, a number of brake mechanisms may be linked together to constitute a group. A control assembly regulates the brake mechanisms of the group.

Abstract: A trailer wheel pivoting system having provision for pivoting of a wheel assembly with respect to an attached trailer frame, accomplished by providing a wheel frame, an axle attached to the wheel frame, road tires attached to the axle, and an apertured cross-bar attached centrally to an upper part of the wheel frame. Various forms of trailer devices are then combined with the aforesaid trailer wheel assembly. In a first embodiment of the present invention, an automobile tow trailer is provided by placing a trailer frame for supporting an automobile onto the wheel assembly, the trailer support frame being provided with a pair of automobile wheel cradles. A pivot pin bolt is inserted through a central aperture in the trailer frame and the aperture in the cross-bar in order to pivotably secure the trailer support frame to the wheel assembly. In a second embodiment, the wheel assembly may serve as an aid for towing trailers.

Abstract: A boat is supported on a wheeled trailer frame by idler rollers and by powered rollers, of a self-adjusting type, located adjacent the rear end of the trailer frame from which the boat is loaded or unloaded. The powered rollers are driven by drive motors through self-locking gears to effect loading or unloading. The boat is held in a transport position on the trailer frame by the powered rollers through the self-locking gearing when the drive motors are de-energized.

Abstract: An apparatus for safely transporting a roll of paper or the like and including the capability of lifting it to a stand or removing it therefrom. The apparatus includes roll supporting ramps and a pair of powered, articulated arms and is supported by air bearings. The device includes safety controls whereby the roll cannot be lifted to or from the pair of roll supporting ramps unless the roll is located at approximately the center of gravity and then the roll is moved along a line substantially vertically above the center of gravity.
