A tow truck carrier with sub frame rails above the carrier chassis frame rails that also reduces platform height thereby presenting a lower center of gravity. Sub frame rails of rectangular steel tubing with the wider dimension of the tubing are used in a horizontal, low profile orientation, with the direct attachment of the lift cylinder ends to the sub frame rails or to a cross beam to lower the platform. The sub frame rails form a descending ladder frame with cross members attached via brackets so that they are lowered into the recess between the chassis side frame. A lifting bracket is welded to the underside of each sub frame rail underneath the overhang and adjacent to the chassis frame to accept the end of a lifting cylinder rod while leaving some space for sliding engagement of a platform beam which engages three edges of the sub frame rail.

A vehicle mounted loading and unloading apparatus is provided which has a stationary mounting rack removably attachable to a roof of a vehicle and a top rack that includes a container for storing cargo, such as bales of hay. An adjustment mechanism is provided to move the top rack relative to the mounting rack from a transporting position to a loading/unloading position in which the top rack is lowered behind the vehicle to facilitate loading cargo. A movable shelf may be provided on the top rack for assisting with loading and unloading cargo. The shelf is slidable between a rear end of the top rack and a front end of the top rack for placing the cargo.

Embodiments of the present disclosure provide a transport vehicle and an installation method for a case of a mobile power generation system. The transport vehicle includes: a chassis and a lifting mechanism assembly located on the chassis. The lifting mechanism assembly includes: a turning frame hinged to the chassis at a hinged position of the chassis, at least one turning hydraulic cylinder connected to the turning frame and the chassis, and a connecting frame configured to be detachably connected to the case. In the main beam, the first body portion is located between the hinged position and the second body portion, and a third plane in which a surface of the second body portion facing towards the turning frame is located is farther away from the connecting frame than the first plane.

A dump trailer comprising an open bed having first and second side walls for partially forming a cargo area to receive construction material and a rear opening for emptying the construction material from the cargo area. A tailgate is provided for covering the rear opening during transport. First and second arms are pivotably coupled to the respective first and second side walls and joined to the tailgate for moving the tailgate between a first position for covering the rear opening and a second position free of the rear opening. Each of the first and second arms are in a position below a top surface of the respective side wall or flush with the top surface when the tailgate is in the first position for facilitating loading of the construction material into the cargo area of the open bed.
