A motorized pallet jack comprises one or more motors that can propel the pallet jack and lift each of the tines. The pallet jack has three tines, and the center tine can be about 2 times the width of each of the left and right tines, though other widths of the center tine can also be implemented. Because the center tine is about twice the width of the left and right tines, two pallets, side-by-side, can be carried simultaneously with only three tines. A portion of the center tine (a right-most portion) and the right tine can have raised areas that enable an operator of the pallet jack to lift a right pallet that sits on the raised areas higher than the left pallet. The left pallet sits on the left tine and center tine without the raised areas (at a lower height). The operator of the pallet jack can place the left pallet in a first location without disengaging the tines from the right pallet, or without lowering the right pallet all the way to the ground (or a first location surface). Alternatively, the raised areas can be located on the left tine and the left-most portion of the center tine, in which case, the operator of the pallet jack can place the right pallet in a first location without disengaging the tines from the left pallet, or without lowering the left pallet all the way to the ground (or a first location surface).

A foldable and portable pallet jack for transporting pallets comprises width-adjustable and folding forks. The skid forks adjust to different sized pallets or materials.

A pallet jack is disclosed that comprises a left tine, center tine, and a right tine. The center tine is about 2 times the width of each of the left and right tines, though other widths of the center tine can also be implemented. Because the center tine is about twice the width of the left and right tines, two pallets, side-by-side, can be carried simultaneously with only three tines. According to another embodiment of the pallet jack, a portion of the center tine (a right-most portion) and the right tine can have raised areas that enable an operator of the pallet jack to lift a right pallet that sits on the raised areas higher than the left pallet. The left pallet sits on the left tine and center tine without the raised areas (at a lower height). Thus, the operator of the pallet jack can place the left pallet in a first location without disengaging the tines from the right pallet, or without lowering the right pallet all the way to the ground (or a first location surface). Alternatively, the raised areas can be located on the left tine and the left-most portion of the center tine, in which case, the operator of the pallet jack can place the right pallet in a first location without disengaging the tines from the left pallet, or without lowering the left pallet all the way to the ground (or a first location surface).

The modular dolly is a manually operated device facilitating the transport of large, heavy, and/or bulky objects. The dolly includes four smaller wheels and two larger diameter wheel and brake assemblies for temporary installation to the sides of the dolly platform for movement over soft, rough, and/or uneven surfaces. A ramp is removably attachable to the loading end of the platform coplanar therewith to facilitate loading the dolly. The ramp also attaches removably to the opposite anchor end of the platform and normal thereto, to serve as a backstop or anchor for a load placed on the platform. A smaller secondary panel may be installed in the anchor end when the ramp is in use during loading, or may be assembled coplanar to the ramp or platform to lengthen the ramp or platform. The dolly may also be used with a stair-climbing hand truck, forklift, pallet jack, or the like.

Material handling vehicles also known as lift trucks, e.g., forklifts, pallet jacks, reach trucks etc., are an essential component of any supply chain and logistics operation. These vehicles are typically driven by human operators and are used to move goods inside factories, warehouses etc. We develop a system and method to retrofit manual lift trucks with a supplemental control system (retrofit kit) that includes sensors, communication devices, computers, electrical circuits and mechanical actuators such that a lift truck can carry out material handling tasks autonomously without the presence of a human operator. The retrofit also allows the lift truck to be controlled remotely by a human tele-operator and can transmit and receive data from a remote computer.

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.
