A system for adjusting the position of a load supported on a conveyor cart includes a driven lift mechanism for controlling height and a turntable for controlling rotational orientation. The cart may, alternately or in addition to the above mechanisms, include a gimbal mechanism for rotational adjustment about multiple axes. A processor on the cart provides actuation and control of the mechanisms. An ID card reader on the cart senses ID tags for determining when the cart is adjacent particular locations. Data representing desired load position at the locations is stored either in a memory device or by the ID tag for relay to the processor on the cart via the ID tag reader. A system level controller provides a centralized storage location for desired load position data for communication to a plurality of conveyor carts through a communication link that includes radio frequency modems.

This invention concerns a new grain unloading system using an integrated ramp, horizontal transfer conveyor and elevating system. The unit is towed, positioned and powered by an agricultural tractor.

A pallet jack with a pallet engaging fork having separate and independently movable first and second fork arms connected to independently controlled and operable first and second fork arm elevating means, for lifting a pallet loaded with a stack of items so that when the stack of items leans and is out of balance one fork arm can be elevated higher than the other to compensate and restore balance to the stack of items.

A preferred embodiment of a folding trailer with kneeling device is disclosed. The trailer includes a kneeling mechanism that is moveable between a traveling position and a kneeling position. The kneeling mechanism includes a pair of control arms that are cantilevered from the ends of a tubular control shaft. The control shaft is hingeably connected to a frame of the trailer. At least one hydraulically actuated cylinder is used to control the positioning of the kneeling mechanism with respect to the frame of the trailer. Placing the kneeling mechanism place in the kneeling position causes the trailer edge of the trailer to be positioned proximate to the ground to facilitate loading and unloading of the trailer.

The present invention is a unitary piece block formed of polymers (such as polystyrene or other high strength polymer) by a single injection molding step which are assembled into a recreational vehicle leveler. The invention ramp provides four sets of four connectors at a top of a floor plate, which are adapted to interlock in cavity structures formed within a cavity on the underside of the block. Two adjacent blocks are secured together by applying to their top surfaces the securing cavity structure of an underside of a third such block. Such blocks can be stacked in an interlocking manner to reduce storage space.

A system for loading cargo containers into a storage hold, and offloading cargo containers from the storage hold, especially of a vehicle, such as an aircraft. The system includes at least one guide rail and a motorized platform, onto which cargo containers are loaded, cooperating mechanically with the guide rail. The guide rail guides the cargo laden motorized platform into the storage hold, and the motorized platform deposits the cargo upon remote command. The motorized platform has a chassis; a power source; a control module controlling drive motors of the wheels of the platform; and means for reciprocating at least a portion of an upper surface of the platform sufficient to elevate a load placed thereon above the guide rail height.

A lift dolly apparatus is described for use in lifting and transporting objects. A latching mechanism is described which securely latches the dolly in the lifted position and can be easily released by using a foot pedal.

A system and method for delivery of packaged goods on a pallet with a pallet jack is described. The pallet jack enables substantially easy navigation over rough terrain through the configuration and placement of the left and right rear wheels and the configuration and placement of the left and right front wheels, as well as the design and implementation of handle bars. Other useful features include a basket for holding personal items, and jacks for retaining hand held devices that can be used to track and update deliveries and orders for goods. Accordingly, the pallet jack is preferably used to deliver consumer soft drink beverages but can be used to deliver any type of packaged product, goods and/or raw materials.

A trailer having a front and a rear. The trailer includes a frame constructed to receive a bed and a hitch attached to the frame at the front of the trailer. A tube is pivotally connected to the frame between the front and the rear of the trailer. First and second support arms are connected to the tube. Each wheel support arm has an axle and a wheel located at its distal end. The trailer further includes means for rotating the tube. In one embodiment, the trailer has an inclining feature and a shoe for ground engagement. The shoe is located vertically below a central axis of the tube and longitudinally between the wheels and the front of the trailer. In a second embodiment, the trailer has an inclining and elevating feature. In this second embodiment, the hitch is pivotally connected to the front of the trailer and there is provided means for rotating the tube and rotating the hitch relative to one another to elevate, incline, or decline the bed.

An adjustable lift dolly apparatus is described for use in repeatedly lifting and transporting objects of different shapes and sizes. A latching mechanism is described which securely latches the dolly in the lifted position and can be easily released by using a foot pedal. A counterbalance is included which prevents the lift dolly from inadvertently moving an object when the lift dolly is in the unlatched position.

A pallet jack includes a hydraulic system that allows for adjustment of the pallet-engaging portion of the jack using a mechanical adjusting system whereby a large variety of pallet sizes can be accommodated. Once the desired width is achieved, the hydraulic system is used to raise the pallet engaging portion of the pallet jack once the pallet is engaged.

As will be discussed in greater detail herein, a transport system is used to move wheeled structures, such as beds. A wheeled bed will be used as the depicted implementation, but other wheeled structures can also be moved by the transport system. The compact design of the transport system allows the transport system when coupled with a bed to be maneuvered through space restricted areas such as elevators.

The present invention relates to a pallet transportation assembly comprising a first tine, a second tine, and a body coupled to the first and second tines comprising a tine adjustment system, a wheel, and a vertical backing portion, wherein the first or second tine further comprises a riser hinged to the first or second tine.

An automotive vehicle having a power-actuated ramp including a vehicle body having a roof, front portion and a rear portion. The vehicle body further includes opposed side portions and a floor that cooperate with the roof, front portion and rear portion to define a passenger area. The vehicle body further includes at least one door to provide boarding and alighting relative to the passenger area. The automotive vehicle further includes a ramp cartridge operatively supported relative to the vehicle's floor. The ramp cartridge includes a frame assembly having a main deck and a ramp assembly having a ramp that is adapted to be retained in a stored position below the main deck. The ramp cartridge further includes a drive assembly adapted to actuate the ramp between a stored position and a first ramp position and between the stored position and a second ramp position.
