An electrically powered truck and system for charging or easily changing the internal rechargeable battery. The truck has an internal rechargeable electric battery which is exposed when a hatch on the truck is opened. The replacement rechargeable battery is inserted into the holding frame once the original rechargeable battery has been removed. The new rechargeable battery is then secured within the truck.

A connector device for connecting a first vehicle to a second vehicle, the connector device comprising an upper frame and a lower frame, where the rear side of the upper frame is configured to pivotally connect to the front upper side of the second vehicle, about a first rotation axis, and the rear side of the lower frame is configured to pivotally connect to the front lower side of the second vehicle, about a second rotation axis that is angular in respect to the first rotation axis. The non-zero angle formed between the rotation axes restricts the rotation movements at least about one of these axes. The connector device can be used for forming a removable chain of main and towed vehicle(s) in a manner that enables folding of a towed vehicle over the first vehicle and removably connecting as many vehicles to be towed as required.

A load-bearing trailer dolly which connects a tongue-type boat, utility or other trailer to a towing tandem trailer and bears weight from the trailer during towing. In a preferred embodiment, the trailer dolly is characterized by an axle mounted on a pair of wheels. A dolly frame height-adjustable trailer hitch centered coaxial above the axle axis and midway point framed dolly plate mount by operation of an adjustable sleeve reducer fastened by pinning and lock. Includes dual connecting adjustable height tongues for attachment to rear end trailer hitches on the tandem towing trailer at which a pair of hitch fasteners for engaging the trailer dolly tongues are attached to the rear of the tandem trailer. The adjustable tongue hitches on trailer dolly will give ability to horizontal level tandem dolly. A shock-absorbing spring is fitted between the axle mount and the dolly frame for cushioning the dolly frame on the axle mount as the trailer is towed behind the towing tandem trailer. In the industry of dollies, the car dolly has no shock-absorbing function, just square axle with hubs for wheels, axle is attached to car dolly frame. There is an option with shock-absorbing mechanism or s non shock-absorbing option.

The present invention comprises a weight distribution tag trailer, having at least some of the following features: (a) a frame assembly, including beams and cross beams and side axle beams, (b) an axle coupled to the frame assembly, (c) shims for optional position between an axle assembly and the side axle beams to allow adjustment of load and balance (d) at least two wheels rotatably mounted to the axle, wherein at least one beam includes an end complementarily sized to be received by a vehicle receiver hitch assembly, and at least one other beam includes a clamp for coupling the beam to a cross frame of the vehicle receiver hitch.

An electric vehicle which operates from a rechargeable battery. The rechargeable battery is contained within an enclosure such that an airspace exists between the rechargeable battery and an interior wall of the enclosure. An aerosol container containing an aerosol electrical insulator communicates with the interior of the enclosure so that when said aerosol container is discharged, the aerosol electrical insulator is released within the airspace to dampen any fire occurring with the rechargeable battery.

A front push collapsible pivoting container and frame with wheels is provided. One aspect provides a front mount trailer assembly, including, but not limited to, a frame having a pivot at a top surface in a first end of the frame; a pair of vertical supports perpendicularly coupled at a second end of the frame; a pair of casting wheels attached to a bottom surface at the first end of the frame; and a container disposed over the frame, wherein a center bottom of the container is connected to the pivot of the frame. Other aspects are described and claimed.

A forward facing vehicle transport apparatus (FFVTA) is provided. The FFVTA includes at least a main support member supported by an axle, and the axle in turn is supported by a wheel. The FFVTA further provides a toe tongue that is secured to the main support member and extends in a first direction from the main support. The toe tongue provides a telescopic extension member communicating with an extension mechanism, the telescopic extension member is configured to interact with a steer axle of a first vehicle, the steer axle supported by a tire of the first vehicle. The FFVTA further includes a pull tongue secured to the main support member and extending in a second direction from then main support. The pull tongue provides a sliding extension member that communicates with an expansion mechanism. The sliding extension member is configured to interact with a fifth wheel of a second vehicle.

A transport system can employ a transport assembly with a main support member attached to a mounting connection, a tow connection, a suspension, and a horizontal articulation mechanism. The horizontal articulation mechanism may be configured to raise the suspension of a ground surface along a first direction and move the main support member in a second direction with the first direction being orthogonal to the second direction.

A dolly for attachment to a vehicle hitch is disclosed. The dolly includes a connection assembly for connecting and disconnecting the dolly to the vehicle hitch. The connection assembly also allows to position the dolly from a ramp position in which the support surface is inclined, to a loading position in which the support surface is raised and parallel to the ground, for loading the object from the dolly to the vehicle. The connection assembly also allows to position the dolly from the loading position to a transport position. In the transport position, the support surface is upright and extends along the rear of the vehicle, for transporting the dolly with the vehicle, once the object has been loaded in the vehicle. A method of operating the dolly is also provided.

The present invention comprises a weight distribution tag trailer, having at least some of the following features: (a) a frame assembly, including beams and cross beams and side axle beams, (b) an axle coupled to the frame assembly, (c) shims for optional position between an axle assembly and the side axle beams to allow adjustment of load and balance (d) at least two wheels rotatably mounted to the axle, wherein at least one beam includes an end complementarily sized to be received by a vehicle receiver hitch assembly, and at least one other beam includes a clamp for coupling the beam to a cross frame of the vehicle receiver hitch.
