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.

A multi-shelf storage apparatus for storage of articles, comprising a wheeled base; a frame disposed on the wheeled base; a plurality of vertically-spaced shelves on the frame for providing a storage area for articles, each shelf configured to move vertically. The apparatus includes a lift mechanism disposed on the frame, coupled to the shelves, and configured to cause collapse and extension of the shelves in a vertical direction. The apparatus has an actuator on the frame operable to drive the lift mechanism, and a power interface on the frame and electrically connected to the actuator. The apparatus has a mechanical connection for connecting to a towing device and a first power interface integral to the mechanical connection such that the actuator can receive electrical power from the towing device. Systems comprising one or more of the apparatuses and methods for loading/unloading articles utilizing the apparatuses are also disclosed.

An apparatus and method for converting a two-wheeled wheelbarrow into a towable cart utilize a detachable towing tongue having a first end adapted for pivotable attachment to an axle of the wheelbarrow between the two wheels, a second end adapted for attachment to a towing vehicle, and a tongue body extending between the first and second ends. The tongue body defines an upper surface that includes a wheelbarrow intermediate support surface configured for engaging a lower surface of the wheelbarrow. In some forms, without detaching the hitch end of the tongue from the towing vehicle, the wheelbarrow may be selectively pivoted between a transport position of the wheelbarrow in which the lower surface of the wheelbarrow is supported by the intermediate support surface of the tongue, and a dump position whereat the lower surface of the wheelbarrow is pivoted away from the intermediate support surface of the tongue.

A mobile extraction assembly includes a sled with a tow line secured to a front end of the sled. The mobile extraction assembly also includes a cart including a frame, a winch, and a pulley. The frame defines a track for receiving and supporting the sled. The winch is mounted to the frame underneath the track. The pulley is vertically disposed in line with or above the track, where the tow line is secured to the winch and routed around the pulley between the winch and the sled. This allows retraction of the tow line by the winch to draw the sled to the cart and onto the track of the cart in a direction towards the pulley.

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.

Implementations of bicycle trailers may include a first end and a second end, the second end opposite the first end, a first plurality of latches coupled to the first end, and a second plurality of latches coupled to the second end. The first plurality of latches may be configured to secure a rear-facing child's car seat facing the first end. The second plurality of latches may be configured to secure the rear-facing child's car seat facing the second end. The second plurality of latches may be configured to secure a front-facing child's car seat facing the first end.

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.

A service cart and associated apparatus that is suitable for servicing electric vehicles and vehicle batteries. The service cart may comprise a frame having a number of members that may be arranged in a compact configuration. The service cart may comprise a number of support pads that may be adjustably arranged with respect to the frame. The support pads may comprise an overload protection mechanism having a break pin. The service cart may comprise a detachable handle operable to selectively disengage a number of brakes on the cart. The service cart may comprise a tow hitch suitable for detachably coupling an external tow device.
