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 trolley case handle and a trolley case are disclosed. The trolley case handle includes a handle body and at least one bracket. The handle body has at least one groove for accommodating the at least one bracket. Each of the at least one bracket is connected to the handle body through a connecting shaft. The connecting shaft functions as a rotation shaft about which the bracket is capable of rotating relative to the handle body. Each of the at least one bracket is provided with a U-shaped notch. In addition, a handle top cover is disposed on a top portion of the handle body. When the handle top cover is in an open state, the connecting shaft is accessible and can be detached from the handle body.

A transportation dolly can have a frame, two axles pivotally coupled with the frame, each axle having two distal ends and a wheel assembly coupled at each distal end and a synchronous steering system. The synchronous steering system can include an intermediate link pivotally coupled with the frame, the intermediate link having a two distal ends, and a first push-pull rod coupling one of the two axles with the intermediate link, and a second push-pull rod coupling the other of the two axles with the intermediate link. The first push-pull rod is coupled to one distal end of the intermediate link and the second push-pull rod is coupled to the opposing distal end of the intermediate link. The first push-pull rod, the second push-pull rod, and the intermediate link provide counter phase synchronous pivoting of the two axles relative to the transportation dolly.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a frame member, a pair of wheels, and a steering mechanism. The chassis defines a longitudinal axis that extends a length of the cart. The frame member is coupled to the chassis of the cart. The pair of wheels are pivotably coupled to the frame member. The steering mechanism is coupled to the pair of wheels. The steering mechanism is configured to facilitate selectively pivoting the pair of wheels to steer the cart in a plurality of steering modes. The plurality of steering modes include at least one of a fore-and-aft steering mode, a turn-on-axis steering mode, and a lateral steering mode.

A pallet sled includes an upper frame including spaced-apart arms adapted to receive feet of a pallet therebetween. A lower frame supports the upper frame. A plurality of pivotable arms connect the lower frame to the upper frame. A handle is pivotably connected to the lower frame and the upper frame, such that pivoting the handle selectively raises and lowers the upper frame relative to the lower frame.

A utility cart includes a flooring apparatus and a pair of wheels. The flooring apparatus includes first and second bracket assemblies and first and second panel members. The first and second panel members are movable relative to the first and second bracket assemblies between an unfolded position in which the first and second panel members extend horizontally and a folded position in which the first and second panel members extend vertically. One wheel of the pair of wheels is attached to the first bracket assembly and another wheel of the pair of wheels is attached to the second bracket assembly. The flooring apparatus is disposed between the pair of wheels when the first and second panel members are in the unfolded position and the folded position.

A smart self-driving system includes a body, such as a piece of luggage, supported by a plurality of wheel assemblies. At least one wheel assemblies includes a wheel rotating motor configured to rotate a wheel of the wheel assembly to move the luggage in a given direction. At least one wheel assemblies includes a wheel orientation sensor configured to measure the orientation of the wheel. At least one wheel assembly includes a wheel orientation motor configured to orient the wheel in the given direction. The smart self-driving system is configured to move in forward direction that is different than a head direction of the body.

A beach wagon for transporting water sport boards and smaller objects. The wagon includes a front wall and the rear wall extending vertically from a floor and engaged to side walls; the wagon is carried on a plurality of wheels. The front wall and the rear wall each include a retaining slot. The retaining slots are in substantial alignment to hold a water sport board in the retaining slots spanning between the front wall and the rear wall. The walls of the wagon retain the smaller objects in the wagon. The slotted front and rear walls can be configured to retrofit existing wagons.

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 steering with shifting system for a camera dolly, including a steering column that can be connected to steering wheels of a camera dolly by first motion transmission means, the steering column being configured to rotate around its central axis in a plurality of positions from a central position to rotate the steering wheels by the first motion transmission means; a handlebar integrally connected to the steering column and configured to be moved to rotate the steering column in a respective position of the plurality of positions; a support body configured to contain the first motion transmission means, the support body including a bell-shaped sleeve coaxial to the steering column, the steering column being at least partly inserted in the bell-shaped sleeve and pivotable with respect to the bell-shaped sleeve; and a central position indication element configured to engage when the steering column is in the central position.
