Truck-type handling truck with a chassis and a back (40), and a low section, a nose plate attachment (41) and two wheels (71). The truck has a motor unit (60) mounted to the chassis (10) and an electric motor (61) connected to a differential transmission (62) with two lateral output shafts (621) and two track modules (50) each connected to a shaft (531) of the motor unit and mounted to swivel about this shaft independently between a position aligned with the chassis and a deployed position.

A self-propelled goods stair climber includes: first and second motorized tracks and an elongated configuration parallel to a straight forward travel direction; a loading surface implemented to tilt with respect to the tracks around a first transverse axis perpendicular to the tracks; an actuated stabilization member movable between an extracted position so that the weight of the stair climber is carried at least in part by the stabilization member and a retracted position in which the stabilization member is not loaded; a proximity or support sensor carried by the stabilization member to send a signal of approach or contact with a floor; an electronic control unit programmed to activate the first and second tracks on the basis of said signal when the stabilization member is extracted; and check an inclination of the loading surface to be maintained in a predefined angular range with respect to a horizontal direction.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A tool support includes a frame that is configured to support a tool and a powered track supported on the frame. The powered track includes a drive roller, an idler roller, and an endless belt that extends around the drive roller and the idler roller. The tool support also includes a first motor supported on the frame. The first motor is operable to drive the drive roller and rotate the endless belt. The tool support further includes a second motor supported by the frame. The second motor is configured to be coupled to the tool to drive the tool supported on the frame.

An electronic cart with an electronic cart body including one or more internal compartments. The cart includes one or more wheels and/or a track assembly supporting the electronic cart body. One or more batteries are carried by the electronic cart body. The cart has a drive system to drive the one or more wheels and/or the track assembly, which is powered, at least in part, by the one or more batteries. One or more hand-operated cart controls are provided on the cart to adjust at least a speed with which the drive system drives the one or more wheels and/or the track assembly.

A portable beach cooler is capable of reducing the temperature of stored items. A main cooling body opens to reveal an ice tray. The ice tray may be connected to a lifting mechanism that allows the ice tray to rise for convenient user access to ice. The lid of the cooling body may have several cupholders traversing through the lid, providing direct access to ice for contained beverages. A cupholder adapter may support beverages atop the lid or may be inverted atop a beverage contained within the cupholder to provide direct beverage access to ice while simultaneously preventing cold air from escaping. A set of tracked wheels is connected to a motorized frame capable of supporting the cooling body. The apparatus may further be equipped with cameras to allow for automatic maneuvering of the motorized frame behind a user, as well as a variety of other electronic ports and devices.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A cart with lifting assistance is provided. The cart includes a forward frame having a top end and a bottom end. The forward frame makes up a front end of the cart. The cart further includes a rearward frame having a top end and a bottom end. The rearward frame makes up a rear end of the cart. Wheels are secured to the bottom ends of the forward frame and the rearward frame. A handle frame extends from at least one of the top ends of the forward frame and the rearward frame, and disposed towards the rear end around a waist height of a user. A pivoting frame is pivotally connected to the front end of the cart and pivots from the front end to beyond the front end. A latch is secured to the pivoting frame and is operable to releasably connect to a bin or container.

Provided is a lightweight crawler unit which is capable of swiveling, suitable for a trolley for bad roads, and used for transportation in muddy places such as snowy roads, sandy ground, and fields, and disaster sites. A crawler includes a plurality of inner attachments provided inside thereof toward a frame to have a band-shape, overhang edges 70 protruding in a left and right direction of a rail provided on a circumference of the frame, and overhang edges 34 protruding in a left and right direction of each of the inner attachments, in a space K enclosed between the overhang edges 34 facing each other, the overhang edges 70 are inserted, the overhang edges 34, 70 are set in a positional relation in which they overlap with each other in an up and down direction, and the crawler circulates around pulleys, while the inner attachments are restricted along the rail.

The tracked stroller frame device may allow a user to take a stroller with them when camping, hiking, or otherwise travelling over rough terrain. The device implements a continuous track system for providing additional tractive area and reducing or eliminating getting stuck on uneven surfaces, and may include a motorized mechanism for providing driving force. The tracked stroller device allows a user to take a baby or young child with them without carrying the baby or young child. The device may be collapsible for ease of storage and transporting and may incorporate a storage area to allow for transporting of other items. A braking system may also be implemented to slow down the device or keep it parked.
