A container moving assembly includes a frame with a drive wheel pivotably attached to the frame about a steering axis. A pair of guide wheels are rotatably attached relative to the frame opposite the drive wheel. A platform lifting assembly is pivotable relative to the frame and includes an engagement platform for supporting a container.

The present invention relates to an electric propulsion system (1) for a rolling object, comprising a chassis (2) with at least one motorized wheel (3) and at least one non-motorized wheel (4), a handlebar (6), coupling means (5) and drive assist means. The coupling means are intended for gripping, orienting, immobilizing and lifting of at least one wheel (14) of rolling object 13). The drive assist means comprise at least one arm (36) of variable length for varying the distance between the at least one driven wheel (3) and the at least one non-driven wheel (4). The present application also concerns a coupled assembly comprising the electric propulsion system and a method of using the electric propulsion system.

A cart has a rectangular forward and rear frame structures both pivoted on a common axle carrying two wheels, lengthwise pieces joining side pieces of the frame structures on both sides, implementing triangular sides for the cart and forming an upper plane, other lengthwise pieces joining a cross pieces of the frame structures to form a support plane parallel to and lesser in width than the upper plane, a central two-inch square metal tubing joined below the forward frame structure from the axle structure to beyond an upper extent of the forward frame structure, a yoke assembly with a single front wheel; and a handle structure joined to the rear frame structure at an upper cross piece. The first and second lengthwise pieces serve as sides to restrain cargo loaded in the cart on the support plane formed by the third and fourth lengthwise pieces.

In this moving body, a walking assist device (1) is provided with: a plurality of drive wheels (50) capable of rotating about a plurality of rotational axes (51) disposed on a circumference centered on the same axis line (C); and a huh case (60) for supporting the plurality of rotational axes (51) so as to be able to revolve around the axis line (C). A first motor (10) is connected to the plurality of drive wheels (50) in a power transmissible manner so as to allow the plurality of drive wheels (50) to rotate, and a second motor (20) is connected to the huh case (60) in a power transmissible manner so as to allow the plurality of drive wheels (50) to revolve.

The improved mobile robot utilizes a cooperative wheeled support arrangement having a unique axle design that preferably cooperates with a base support module. A tri-axle is preferably used to support at least one omni-wheel on each axle section. Multiple omni-wheels on each section can be used for higher load applications. The tri-axle is of a fixed design and each wheel pivots on the individual axle section. Preferably, the axle sections are welded to each other.

A battery-powered dolly in one aspect of the present disclosure includes a handle, a connector, a motor, a wheel, a detector, a rotation information acquirer and a controller. The controller stops supplying an electric power from a battery to the motor based on (i) a battery current value and/or a battery voltage value detected by the detector and (ii) a rotation information acquired by the rotation information acquirer.
