A vehicle conveyor includes a slide member that is provided on each of opposite side faces of a carriage portion, and slides along a longitudinal direction of the carriage portion, independently of the carriage portion. A first arm set and first arm actuators are joined to the slide members, and are configured to slide along the longitudinal direction of the carriage portion, integrally with the slide members, independently of the carriage portion.

Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes a frame having an upper ledge; an extendible leg coupled to the frame, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer parked on a driveway based on movement of the extendible leg relative to the frame; a wheel connected to the frame, the wheel to remain at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved.

A walking trailer stand including a mobile trailer assembly, a trailer stand assembly, and a reversible feet assembly is disclosed. These assemblies allow for the manually powered movement of a mobile trailer. The trailer stand assembly including a leg holder to receive a bottom end of a trailer A-frame. The leg holder being mounted to either side of a base via a bracket. The base including a jack guide extending from a base top end and an internally mounted jack holder. Wherein the jack guide and jack holder receive a jack member therein to form a fulcrum to allow a user to lift and drop the trailer A-frame. The reversible feet assembly including reversible feet that include a rubberized portion and an oppositely arranged cleated portion. The reversible feet are mounted to an underside of the base so the trailer may be walked with the actuation of the jack member.

Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: a frame having an upper ledge, a post, and a lower subframe, the lower subframe connected to the upper ledge via the post; an extendible leg coupled to the post independent of the lower subframe, the upper ledge being vertically movable based on movement of the extendible leg relative to the upper ledge, the post, and the lower subframe of the frame; and a wheel connected to the frame via the lower subframe such that the wheel is to move with the upper ledge as the upper ledge is vertically moved.

A number of dolly assemblies are connected in series with chain linkage sections to form an endless conveyor chain for the dolly assemblies to move objects along a track. Each dolly assembly includes a link attachment and a wheel assembly supported by the link attachment. The link attachment includes a base and a body portion. The body portion presents an open-loop partially surrounding an interior and extending between a pair of ends. The ends are spaced from one another to define an opening to the interior therebetween. The pair of ends are also formed in toward the interior to partially surround a respective pocket. Each pocket is configured to receive a portion of an endlink of a respective chain linkage section therein, and each one of the formed ends functions to prevent the endlink of the respective chain linkage section from becoming unhooked from the body portion.

Described herein is a sliding device (1) designed to receive a vehicle (7). The sliding device includes a frame (5) on which the vehicle is intended to be received, at least three sliding wheels (3a-d) vertically adjustable relative to the frame and each wheel operatively connected to the frame via at least one vertically disposed rotatable shaft (9a-d), a plurality of vertical folding shafts (19a-d) connected to the frame, a plurality of cross bars (14a-b, 15a-b) elevated relative to the frame, the cross bars are operatively connected to the wheels via the rotatable shafts (9a-d), and pivotally connected to the frame via the vertical folding shafts (19a-d) so that each of the cross bars is movable between a folded and an unfolded position (3), and a folding lock (21) adapted to lock the vertical folding shaft (19a-d) relative the frame in the unfolded position to prevent it from being turned.

In some embodiments, a mobile robot unit for engaging a wheel of parked target vehicle is provided, the mobile robot unit comprising: a frame adjustable from a first configuration to a second configuration and vice versa, wherein in the second configuration the frame engages the vehicle wheel to apply a sufficient counterforce onto the vehicle wheel to lift the vehicle wheel and the vehicle weight supported by the vehicle wheel from the ground; and at least two wheel assemblies supporting the frame above the ground, each wheel assembly comprising at least one steerable wheel, the steerable wheel contacting the ground.

A first arm set and first arm actuators are joined to the slide members, and are configured to slide along the longitudinal direction of the carriage portion, integrally with the slide members, independently of the carriage portion.

A trailer dolly can include various features to be adjustable between a manual configuration and a vehicular towing configuration. In the manual configuration, a user can manually maneuver the trailer dolly to position the trailer, such as by using one or more retractable handles. Where the user desires to maneuver the trailer with a vehicle, the trailer dolly can be adjusted to the vehicle towing configuration. In an example, the trailer dolly can be coupled to the vehicle with a second hitch attached to the trailer dolly, the second hitch located distally along the tow bar with respect to the trailer hitch supporting the trailer load. Accordingly, the trailer dolly can be used for both manual and vehicular applications and the user can transition between the manual and vehicular configurations while the trailer is hitched to the trailer dolly.
