A vehicle, in particular an industrial truck, comprising at least one support roller and a method for stabilizing a vehicle.

A hand truck (10) comprises a frame (12), a platform (14) for carrying a load, an axle (26), two wheels (16) mounted on the axle (26), axle guide members (42), and biasing means (30). The axle (26) is moveable along the axle guide members (42) to move the axle (26) relative to the platform (14). The biasing means (30) compresses to resist tilting of the hand truck (10).

A pallet lift includes a base and a deck extending forward of the base. Load wheels support the deck. A platform above the deck is pivotable relative to the base. The platform has an upper support surface for supporting objects thereon. The platform may be pivoted as the pallet lift travels on an inclined surface, such as a truck ramp, in order to keep the platform relatively level relative to gravity to increase stability.

A cart for transporting an aquatic vessel is provided which includes an axle, at least two wheels arranged on the axle, a frame having support posts extending from the frame to support the aquatic vessel, at least two elongated ties secured to the frame or the support posts, each having a wheel chock arranged thereon configured to be removably placed adjacent to one of the at least two wheels to stabilize the cart at rest, and a kickstand. The cart and its components can be disassembled in a variety of different configurations to allow the cart to be stored in a number of different configurations, including inside of the aquatic vessel, when the cart is not in use.

A locomotion platform comprising: a base frame having front and rear lowermost sections, both defining an imaginary horizontal landing plane; front and rear wheel assemblies, each configured with a distal end comprising riding wheel(s) and at least one proximal end articulated to said base frame, each of said front and rear wheel assemblies independently manipulable between a collapsed position, at which the riding wheels of the respective wheel assembly are disposed on or above the plane, and an extended position, at which the riding wheels of the respective wheel assembly are disposed below the plane; a position fixing mechanism(s) configured to selectively arrest at least one of said front or rear wheel assemblies at one or more intermediate positions between the collapsed and extended positions; and an activating module(s) configured to induce manipulation of at least one of said front or rear wheel assemblies towards the collapsed position.

A transport truck for transport of components, pellets, gitterboxes and similar is in the bottom part of a main frame equipped with at least one couple of vertical fixed pins for pivoting connection in the range of 360 into laterally deflected forks in which are pivoted wheels where the essence of the invention consist in that between the front and the rear wheels is transversally pivoted a shaft whose end parts are placed in bearing housings and are firmly fixed to pivoted scooter forks which are a fastener of foldable revolving wheels and the pivoted shaft is firmly fixed to at least one one-arm lever whose second end part is fixed, by the help of a pin, to control mechanical or mechanical-hydraulic means which are connected through a pin connection with a lever arm of a control lever which is together with a scooter fork with holes of a multifunctional shaft pivoted on a pin placed in a holder which is firmly fixed to the main frame of the transport truck.

A load wheel assembly for a pallet truck includes a first load arm that rotates about an axis of rotation, and a load wheel rotationally coupled to an end of the first load arm opposite from the axis of rotation. The load wheel supports a fork at an elevation above the load wheel. Additionally, the load wheel assembly includes a second load arm pivotally coupled to the first load arm at the axis of rotation and forming a load arm angle, and an adjustment mechanism further coupling the second load arm to the first load arm. The adjustment mechanism varies the load arm angle formed between the first load arm and the second load arm to adjust the elevation of the fork above the load wheel.

The present invention provides a transformable bicycle. The transformable bicycle including: a pair of front fork members which are connected to a front wheel, and which are arranged with the front wheel interposed therebetween; a head tube which is connected a fork support bar; a frame which is coupled to the head tube, and which is connected such that the head tube is rotatable around a bolt pin; a fastening device which is connected to the head tube; another fastening device which is installed with the fastening device and a spring interposed therebetween; a fastening device handle which allows the front fork members to be folded toward the frame in such a manner that the fastening device handle rotates the head tube connected to the fastening devices around the bolt pin by pulling the fastening devices during rotation around pins; a seat; and a rear wheel.

In an aspect a vehicle is provided, and includes a frame a front wheel and a rear assembly. The front wheel is rotatably mounted to the frame. The rear assembly includes a first rear wheel support and a second rear wheel support. Each of the wheel supports is movably mounted to the frame. The rear assembly further includes a first rear wheel and a second rear wheel. The first and second rear wheels are rotatably mounted to the first rear wheel supports respectively. The rear assembly is positionable in a first position in which the first and second rear wheels are substantially immediately adjacent one another to operate as a single rear wheel, and a second position in which the first and second rear wheels are spaced apart from one another.

A large cargo dolly has a first central tube and a cross bar integral with and perpendicular to the first central tube. The cross bar has a hollow first end and a hollow second end. Further, the large cargo dolly has a first moveable tube having a circumference that is smaller than a circumference of the cross bar, and the first moveable tube moveably is coupled within the hollow first end of the cross bar and fixedly coupled to a first wheel. The first moveable tube is adjustable to fit a size of cargo placed on the first central tube and the cross bar, and the first wheel is configured to automatically adjust when the first moveable tube is adjusted. The large cargo dolly also has a second moveable tube having a circumference that is smaller than the circumference of the cross bar, and the second moveable tube is moveably coupled within the hollow second end of the cross bar and fixedly coupled to a second wheel. Furthermore, the second moveable tube is adjustable to fit the size of the cargo placed on the first central tube and the cross bar, and the first wheel is configured to automatically adjust when the second moveable tube is adjusted.
