A rotatable trailer bed includes a frame, a trailer bed, a turntable swivel assembly, and a plurality of swivel casters. The frame includes a bed section, a hitch section, and two wheel sets. The hitch section is adjacently connected a front end of the bed section. The two wheel sets is rotatably mounted to the bed section. The plurality of swivel casters is mounted to the bed section is perimetrically positioned around the bed section. The trailer bed is rotatably mounted to the bed section through the turntable swivel assembly as the plurality of swivel casters maintain the balance and level of the trailer bed.

A platform having adjustable working areas that can be repositioned from a stored position to an operational position on the platform wherein each of the work areas are horizontally adjustable to allow each of the work areas to be independently adjustable.

An invention relates to picking, storing, and transporting of products. One objective is to reduce or eliminate manual work, or unnecessary process stages. The invention concerns a trailer (100) for a delivery of the products, wherein the trailer comprises an attachment point (101) for attaching the trailer to a road vehicle, a body with wheels, and a wall (104) attached to the body. The wall includes openings (105, 106) to a trunk that is limited by at least the body and the wall. The trailer comprises closures (109, 110) to cover and disclose the openings, and the trailer is configured to open a first closure (109) in response to a correct identifier. The trailer is further configured to receive a cart to a storing place so that, at the storing place (111), the cart holds a first repository (107) beside the first opening and a second repository (108) beside the second opening.

A waste removal system with a trailer for the storage of materials such as waste or rubble, wherein said trailer has a front wall a rear wall and plurality of side walls with an extended slope on at least one of said walls to increase the volume capacity therein. The trailer may additionally contain a slanted access door or ramp which alternatively raises and lowers, allowing for ease of ingress and egress of the trailer volume. The waste removal system may additionally include a transport vehicle with a grappler mounted at a distal end of a boom, wherein said grappler grasps waste and deposits said waste into the previously-mentioned trailer for transport to and from a desired location.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.
