Provided herein is a wheeled cart useful for the transport of children and/or other cargo. The wheeled cart comprises a steerable member that permits user-controlled movement of the front wheel and hence steering while retaining contact of all three wheels with the walking or running surface. Inventive wheeled carts are suitable for use by the user while walking or running and simultaneous transport of a child and/or other cargo, provide a roll-cage for protection of the child and/or cargo in the event or a roll-over accident, and are advantageously adapted for folding and ease of transport when not in use.

A roll cage for a model car or truck is made of first and second elongated members and first and second inverted U-shaped cross members fabricated from flat metal stock. The roll cage is assembled by slip-fitting it together at mating slots formed into the elongated roll cage members and the inverted U-shaped roll cage members. A rigid roll cage is formed, which then is attached to the chassis of the model car or truck to overlie the components mounted on that chassis.

A three wheel electric vehicle platform with two wheels in front and one wheel at the rear, a full safety roll cage, a propulsion and steering system operating through the two front wheels, and operator's and passenger's seats mounted in-line along the vehicle centerline. The propulsion system is an electric motor powered by an energy storage device driving a speed reduction and differential with dual outputs suitable for two wheel front drive. The operator's seat is narrower in parts than a conventional automotive seat such that the rear seat passenger's knees can comfortably straddle the operator seat to allow the distance between the two occupants to be less than a typical automobile. The driver's and passenger's heels comfortably fit into recessed wells within the energy storage device, thus allowing the driver's and passenger's center of gravity to be lower, while still maintaining a comfortable sitting position.

A wheelbarrow may include a receiving or load carrying portion, such as a tub or container, and wheels. The wheels are preferably disposed proximate a central portion of the tub. The wheelbarrow may also include a frame with a base or platform, which may connect the wheels and load carrying portion. In addition, the wheelbarrow may include a handle that is connected to the base or platform. A substantial portion of the capacity of the tub may be disposed below the handle and/or a substantial portion of the capacity of the tub may be disposed above the handle, which may help increase the stability and/or load capacity of the wheelbarrow. The frame may also include a front dump roll cage, which may be connected to the base or platform. The front dump roll cage may help support the tub, may help provide more stable dumping and/or may help protect the tub from damage

A continuous autoclave comprises a tank body and a material transport unit arranged in the tank body, wherein the tank body is internally provided with a high temperature hot water sterilization cabin, a low temperature cold water cooling cabin, a hot water circulating device, a heat (hot water) recovery device and a roll cage which is used for accommodating materials and is driven by the material transport unit; the material transport unit is a chain transport unit in multilayer continuous transmission, and chains operate in a layer-by-layer rising mode in the high temperature hot water sterilization cabin area and operates in a layer-by-layer declining mode in the low temperature cold water cooling cabin area. The autoclave in the invention is especially suitable for sterilizing products packed by thermophilic digestion bags and foods packed in other structural forms.

A roll cage assembly, for use on a vehicle, includes one or more structural components. At least one roll cage displacement assembly is coupled to the one or more structural components and the vehicle. The at least one roll cage displacement assembly is configured to allow for displacement of the one or more structural components with respect to the vehicle.

The invention discloses a vehicle body of an all-terrain vehicle, and the vehicle body is a unitary-construction welding combined body. The vehicle body comprises a unitary-construction baseplate welding combination (1), a left body welding combination (2), a right body welding combination (25), a left vice box welding combination (3), a right vice box welding combination (31), a front panel welding combination (4) and a rear panel welding combination (5); and the middle parts and rear parts of horizontal planes of left and right vice boxes are respectively provided with a front antiroll rack (7) and a rear antiroll rack (6). Because a shoal-water baffle technique that the upper edges of front and rear peripheries of the vehicle body are protruded and an inclined angle is formed between each upper edge and the horizontal plane is adopted, and a technique that an upper peripheral opening of the vehicle body is cavity-shaped is adopted, the cross-country power of the vehicle body when the vehicle body is running ashore, offshore and on rugged road surfaces is effectively improved, and the problem of underwater floatability and stability is solved. A shell of the vehicle body is prepared by welding and splicing high-strength plates, therefore, the vehicle body is high in strength, strong in striking-resistant capacity, small in mass and low in center of gravity.
