A handcart is provided that includes a frame, wheels, and a motor that drives the rotation of the wheels. The number of wheels is two. The handcart includes a platform coupled to the frame, including a base and a vertical structure. It allows providing a self-propelled handcart with the two wheels and a variable length chassis that is as simple, safe to use, and inexpensive.

A multipurpose mobile utility lifting ergonomic cart consists of a structural frame, a platform, at least one insert, a plurality of wheels, and a height-adjustable arm. The height-adjustable arm extends from the structural frame and is connected to the platform so that the platform can be positioned at varying heights. The platform provides workspace for the user by being attached to the at least one insert that can be, but is not limited to, a dish drying rack, a podium insert, or a house cleaner rack. The structural frame can be used for holding items such as boxes or cleaning supplies. The plurality of wheels allows the user to move the apparatus from one location to another.

An anti-tilt device for a caster that includes a wheel, rotatably mounted in a frame, for rotation about a rotation axis. The anti-tilt device, comprising first and second face plates; first and second flanges extending from opposing edges of said first plate, each of the first and second flanges wrapping beside the first face plate; first and second flanges extending from opposing edges of said second face plate, each of the first and second flange extending beside the first face plate, to prevent rotation of the first and second face plates when mounted to the caster frame; first and second legs extending from the first second face plates, respectively; and a bar, extending between the first and second legs across a tread face of said caster wheel when mounted to said frame, at a defined angle of the tread face, as measured from a vertical axis extending through said rotation axis, when said caster is level. Each of said first and second legs includes a defined bend to place said bar at said defined angle.

Various embodiments of a system for tracking and/or controlling wheeled vehicles (such as shopping carts), are described. In some embodiments, the system includes an RFID tag on the cart and an RFID reader device external to the cart. The tag can receive an interrogation signal from the reader and reply with a response signal. In various embodiments, the reader or a central control unit can perform various calculations based on the response signal, such as generating a received signal strength indication (RSSI) value. In some embodiments, based on the RSSI value or otherwise, the reader can send a command signal to the tag to take an action, such as to engage a brake mechanism.

A motorized cart with a frame, the frame having a floor, a first elongated side wall, a second elongated side wall, a rear wall, and a front wall that is hingedly connected to the floor. The cart includes a winch that is situated on the rear wall of the cart. A winch belt with a hook on the end of it extends forward from the rear wall. The cart has two wheels that are longitudinally aligned with one another so that one wheel is directly in front of the other wheel, and the wheels are centered longitudinally within the floor of the cart. The cart also has an electric motor that is powered by a battery and is operable in both forward and reverse gear.

An improved cargo dolly for transporting cargo is described having a mobile dolly frame, a main shaft on the frame, a lever proximate to a first part of the frame (where the lever is movable relative to the frame and in responsive communication with the main shaft), a first set of transfer sprockets mounted to the main shaft, a secondary shaft rotatably disposed at a second part of the frame (where the first part is remote from the second part), a second set of transfer sprockets mounted to the secondary shaft, a chain disposed about the first set of transfer sprockets and the second set of transfer sprockets, and a locking pin having a first end fixed to the secondary shaft and a second end configured as an angled latch. Rotation of the lever responsively causes the locking pin to remotely rotate at the second part of the frame.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers to large sealable container bins on wheels, to provide large quantities of water to remote areas not served by public water supplies, or where water supplies are unavailable because of weather disasters. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.

A cart for transporting items comprises a base portion, comprising: a frame; at least one shelf coupled to the frame; and a set of wheels at the bottom of the frame permitting a movement of the cart; and a collapsible ladder directly attached to the frame.

A pallet sled includes a base and a plurality of tines extending forward from the base. At least one of the plurality of tines includes a wheel supporting the tine away from the base. A brake assembly is positioned adjacent the wheel to selectively brake the wheel. The brake assembly may include a drum adjacent the wheel. Alternatively, the brake assembly may include a brake shoe selectively directly contacting the wheel to brake the sled.
