An apparatus for loading and unloading containers of various sizes onto and off of a roll-off vehicle comprises a top frame and at least one lift actuator operable to pivot the top frame away from a horizontal home position to rearwardly incline the top frame. The top frame includes a main portion, a head portion longitudinally displaceable relative to the main portion, a plurality of sheaves, a cable extending through the sheaves, and a hoist actuator operable to displace the head portion between a retracted position and an extended position. The cable has a fixed end coupled to the head portion and a free end for coupling to a container. The hoist actuator is operated while the top frame is away from the home position to displace the head portion toward the extended position to load a container onto the vehicle, and toward the retracted position to unload the container.

A vehicle tailgate assembly comprises a frame with a transverse base and support arms extending perpendicularly therefrom adjacent distal ends of the base, a central section also extending perpendicularly from the base but to a lesser extent than the support arms, a door rotationally mounted to the frame between the support arms, the door being profiled with a central opening matching the central section and aligned therewith in a co-planar manner when the door is in a fully closed position, a mating portion comprising an indentation in the door adapted to mate with the central section when the door is rotated 180 degrees from the fully closed position to a working position to expose the central opening with the door co-planar with the frame.

The present invention relates to a monopile fastening system for retaining one or more elongated monopile during sea transport and/or quay transport, which can be used to accommodate monopiles with section having different diameters by the combination of complementary supporting elements that can be singularly activated.

The present invention also relates to a monopile fastening structure comprising a plurality of monopile fastening systems, and to a vessel, a barge or a sea transport unit comprising a monopile fastening structure or a monopile fastening system and to a method for fastening a monopile using a monopile fastening system.

A vehicle bed extender adapted for simultaneous adjustment of both length and width. The extender includes a first side wall, a second side wall, and a connecting wall. The first and second side walls can attach to the vehicle storage bed, while the connecting wall attaches to the side walls in a sliding configuration along a direction nonparallel to the length and width of the bed extender. The connecting wall can also be composed of multiple cross members with middle portions of varying length such that the middle portions of the cross members are not vertically oriented. The vehicle bed extender can also be supported by a mount at the front end of the vehicle bed that supports the connecting wall.

A pickup truck rack includes a fastening base, a support frame, a fastening rod, and a fastening frame. There are two fastening bases. One support frame is fastened on each of upper ends of the two fastening bases. Rail grooves are provided at both an upper end and a lower end of the fastening rod. The fastening frame and two support frames are respectively disposed at the upper end and lower end of the fastening rod and are reciprocable or fixable along the corresponding rail grooves. The support frame is a retractable support frame formed by an inner tube and an outer tube that are sleeved. A vertical sliding groove is opened on the inner tube. A clip is provided inside the sliding groove. A bolt through hole is provided at an upper end of the outer tube.

Provided herein is a split variable extension width self-propelled motorized transporter (SPMT) vehicle including a widening adaptor that allows for variable spacing of split SPMT trailers thus increasing the width of the loading platform without the need to add more SPMTs and Power Pack Units (PPUs).
