A pallet jack includes a base and a pair of tines extending from the base. The pair of tines including a first tine and a second tine. A load wheel supports an outer end of each of the pair of tines. Each load wheel is configured to move toward and away from the respective tine to raise the tine off a floor on which the load wheel is supported. The first tine including a support surface configured to selectively be a lowermost surface of the tine to facilitate lateral displacement of the first tine.

A mobile body that is human-powered includes three all-directional wheels with axles thereof displaced from each other by 120 degrees, a connection portion that connects two front wheels, a brake attached to a rear wheel, and a disconnection portion that disconnects the two front wheels from each other. The connection portion connects the two front wheels such that the two front wheels rotate in directions opposite to each other. The connection portion connects the front wheels with the rear wheel such that the two front wheels rotate in the same direction, while the front wheels rotate in a direction opposite to a rotational direction of the rear wheel.

A pallet sled includes a pair of tines extending forward from a base. A load wheel supports each of the pair of tines. The load wheels are each configured to move away from the respective tine to lift the respective tine upward relative to a support surface on which the load wheel is supported. A processor on the pallet sled records usage of the sled, such as lift cycles, location over time, battery condition, lift height, weight lifted, distance traveled, and the like. A communication circuit may be configured to send data from the pallet sled to a remote server. An identification reader may be configured to read an identification tag of an object supported on the pair of tines, such as an rfid tag on a pallet.

Examples includes systems and methods for lifting and moving gondolas using a modular gondola moving system. Components of a modular gondola moving system include interchangeable skates. The interchangeable skates are further removably attached to a longitudinal member which, when connected to the longitudinal member, form a skate system. Multiple skate systems are positioned to the underside of a gondola and may additionally be connected together by connector bars for stabilization and to form the modular gondola moving system. One or more lifting devices are provided independent of and are used in combination with each skate system for positioning the gondola on each skate system. The one or more lifting devices may be repeatedly used in order to place the gondola on a single modular gondola support system.

A pallet truck according to the present application includes a front frame, a rear frame, a lifting component, two fork bodies, a guide bar, a transmission device, and a load-bearing wheel assembly. The distance between the fork bodies can be adjusted by using the side-shifting driving component, thereby providing different fork distances and significantly improving the adaptability. During the adjusting process, the transmission device can switch the load-bearing wheel assembly from the longitudinal rolling state to the lateral rolling state, thereby avoiding wear of the wheels, which is beneficial to improving the overall life of the device and reducing the maintenance cost. In addition, the transmission device is pushed out as the rear frame is lifted, and thus the operation process is simple and reliable.

A bidirectional trolley (1) comprising a drawbar (Abstract2), two pivoting front wheels (6, 6′) a push handle (3), a loading and unloading plan (4) for a box (5) for moving items. The bidirectional trolley comprises a rotary system (10), placed in the rear portion of the trolley (1), and comprising two non-pivoting wheels (8′, 8″) placed on the same horizontal axis, a pivoting wheel (8) placed at 45° with respect to the other two non-pivoting wheels (8′, 8″) and a hook (12), configured for assuming a resting position in which it is completely retracted under the plan (4) between the two non-pivoting wheels (8′ and 8″), in order to permit to an operator to approach the most to the box (5) for moving items, for an easy unloading and loading of the box (5) itself.

Certain exemplary embodiments can provide a dolly comprising a frame, a set of guide rollers, a planetary disc, a set of rollers, and a caster. The frame comprises a plurality of cells. The set of guide rollers is coupled to the frame. The planetary disc constrained within a cell of the plurality of cells via the guide rollers. The set of rollers is coupled to the cell of the plurality of cells. Each of the plurality of rollers contacts a surface of the planetary disc. The set of rollers is constructed to distribute a load placed on the dolly over a surface of the planetary disc, thereby reducing a probability of failure of the dolly. The caster is coupled to the planetary disc.

A pallet sled includes a pair of tines extending forward from a base. A camera is mounted on the pallet sled and is configured to record images, such as video, as the pallet sled brings pallets of items from a truck into a store. At least one processor is used to analyze the images from the pallet sled. The images are used to determine inventory levels in the store, conditions of the store, conditions of the pathways of the pallet sled. An accelerometer on the pallet sled detects hard braking and accidents.

Bidirectional trolley (1) comprising a movable drawbar (2), a push handle (3), a loading and unloading plan (5), two front wheels (4, 4′) and two rear wheels (40, 40′) connected to the loading and unloading plan (5). A handling system (10) comprising in turn a first toothed means (8) connected by meshing to the front wheel (4), and a second toothed means (80) connected, again by meshing, to the rear wheel (40), in which the first toothed means (8) and the second toothed means (80) are connected to each other by a connecting bar (9) which allows the joint movement of the two toothed means (8, 80) as a result of the movement of the drawbar (2) by means of the push handle (3) by the user.
