A wheels assembly, including at least a first subsidiary wheels assembly, each including a) a first profile, for carrying a board, and b) a first cart being tiltably slidable along the first profile, and including wheels, and a second subsidiary wheels assembly including a) a second profile, for carrying the board, b) a second cart being tiltably slidable in relation to the second profile, and including wheels, and c) a user-adjustable bolt, for adjusting the tilted sliding of second cart in relation to the second profile, for adjusting a vertical distance therebetween, where the second profile of the second subsidiary wheels assembly is fixed to the second profile of one of the at least first subsidiary wheels assembly.

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.

An Urban Intermodal Freight System is capable of transporting large volumes and tonnage of freight by containerized or other means on a mass transit rail system. It captures excess capacity in the existing mass transit rail infrastructure to move packages, parcels, and freight by using miniaturized intermodal cargo containers that are designed to integrate seamlessly with the existing transit infrastructure, while displacing delivery trucks from increasingly crowded city streets. By enabling inbound trucks to transfer their cargo to the Urban Intermodal Freight System at a city's outskirts, freight is delivered without trucks entering congested downtown areas, greatly alleviating traffic congestion, delays, greenhouse gas emissions and other negative environmental impacts. The Linear Loading Dock and Conveyor System may have other useful applications, for example to access a facility, building or vehicle, or in other circumstances where off street truck parking or loading docks are not available.

An industrial truck includes a vehicle frame and a drive unit. The drive unit includes a drive wheel movably mounted to the vehicle frame and a spring unit. The spring unit includes a hydraulic cylinder positioned between the vehicle frame and the drive unit and a switchable valve configured to define a blocked state. The spring unit is configured to pretension the drive wheel against a ground surface. When the switchable valve is in the blocked state, a one-sided movement of the hydraulic cylinder is blocked.

A mobile transport system for transporting objects in a technical system, includes a vehicle frame, a first wheel pair, a second wheel pair, and a third wheel pair, each having two wheels rotatable relative to the vehicle frame, and a swing frame pivotable about a swing axis extending in a transverse direction relative to the vehicle frame. The first wheels of the first wheel pair are attached to the vehicle frame, and the second wheels of the second wheel pair are attached to the swing frame. The third wheels of the third wheel pair are attached to a tilt frame pivotable relative to the swing frame about a tilt axis extending approximately in the longitudinal direction.

A multi-terrain cart, comprising a cart body, two front and two rear non-pivoting wheels, a swivel wheel positioned forwardly or rearwardly to the front and rear non-pivoting wheels, respectively, an actuator for applying a downward force to the swivel wheel which causes the swivel wheel to be set at an operative position and two of the non-pivoting wheels to be raised relative to an underlying ground surface, and means for setting an angle of the swivel wheel relative to a lengthwise extending centerline of the cart body to cause the cart to rotate about a center of rotation that is determined by the set angle of the swivel wheel.

A foldable golf trolley comprising a chassis; at least one electrically powered rear drive wheel; a wheel support arm mounted to the front of the chassis supporting a front wheel; a stabilizer arm mounted to the rear of the chassis supporting a stabilizer wheel; a main support mounted to the chassis and a handle mounted to the main support; wherein the main support, the wheel support arm and the stabilizer arm are rotatably mounted to the chassis and movable between an operative configuration and a folded configuration; and gears connecting the stabilizer arm and main support, wherein rotation of the main support between the operative configuration and the folded configuration cause rotation of the stabilizer arm between the operative configuration and the folded configuration.

A pull-behind carriage has an auxiliary wheel mounted on a reconfigurable drawbar. When the pull-behind carriage is converted to a push carriage, the drawbar is folded so that the auxiliary wheel is positioned on the ground to act as an extra, supporting wheel. Joints in the drawbar are palm operated and can be rotated without continuing to hold the joint. The drawbar may also serve to move the axle of the main wheels backwards when the carriage is converted from the pull-behind mode to the push mode.

Embodiments of the disclosure enable a cart to be stabilized. A stabilizing mechanism includes a body having a first surface and a second surface that define an elongated nook configured to receive a first rod member. A coupling device is coupled to the body at a third surface such that the coupling device is substantially parallel to the first and/or second surfaces. The coupling device defines an elongated channel configured to receive a second rod member. A wheel assembly is coupled to the body at a fourth surface and includes a first end portion, a second end portion, and a plurality of wheels rotatable about an axis of rotation. A first wheel is coupled to the first end portion, and a second wheel is coupled to the second end portion. Aspects of the disclosure provide for utilizing the cart to move a load across various terrains efficiently and effectively.
