A self-contained heated portable vacuum slurry box which is constructed to hold both a positive pressure and a vacuum pressure. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The slurry box meets space restriction requirements while functioning within the environmental conditions of winter and summer seasons.

A pallet and a transport device for the pallet. The pallet, includes a frame having a-side parts and a rod that extends between the side parts. A span of the rod is at least half of the length of the rod. The pallet includes foot arrangements having parts configured to guide the pallet onto a bed of the transport device. The transport device includes the bed, a chassis and articulations enabling rotation of the bed relative to the chassis. The bed includes side beams that are configured to engage with the parts of the foot arrangements thereby guiding the pallet onto the bed. A system includes the pallet and the transport device.

The present invention is a method and a device for tracking the unloading and loading of containers from and onto carrying platforms of tracks, using unloading and loading motion activity time course patterns characteristic of a specific container in combination with a specific carrying platform of a truck. In the invention the device is connected to a specific container and records the tilting angle of the container in the time course of unloading and/or loading from and onto a specific platform of the truck. A digital data processor produces from the data a motion activity time course pattern curve which is compared and matched for fitness to a predetermined standard motion activity time course pattern curve for the specific container and specific carrying platform of a truck and sends the degree of fitness to a data receiving terminal system. If the fitness of the two curves is found to be in close fitness, together with GPS data from the device, it is possible to determine if, where and when unloading and loading of the specific container took place.

Provided in this disclosure is a hoist for raising and mounting an interchangeable vehicle body onto a vehicle chassis. The hoist includes a hoist frame having a pivot end and an elevated end for slidably supporting the interchangeable body. A subframe with a bolt-on assembly is provided for fixedly connecting to the vehicle chassis. A linkage connects the hoist frame to the subframe. The linkage also includes a hinge joint member for raising the elevated end of the hoist frame. A hinge assembly pivotally connects to the pivot end of the hoist frame. The hinge assembly has a bolt-on mounting bracket for fixedly connecting to the vehicle chassis. A winch assembly is retained in the elevated end of the hoist frame and extending beyond the pivot end for raising the interchangeable body onto the hoist frame.

A plastic roll-off container is disclosed, including a roll-off container comprising a front side and a rear side. The roll-off container is configured, via a first rail and a second rai positioned on a bottom side of the roll-off container, to be onloaded, offloaded, and transported by a roll-off truck or a hook lift roll-off truck. An integrally molded sidewall is connected to a bottom having a concave shape to facilitate the removal of a material from an interior of the roll-off container.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

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 locking mechanism has a guide and a vertically movable plate. The plate is movable in the guide under gravitational influence between a locked position and an unlocked position. A slot is formed in the plate to receive a guide pin. The guide pin maintains the movable plate in the guide. The slot enables axial vertical movement of the plate in the guide. The plate moves into the locked position upon contact with a surface. In this position, the plate projects from the guide to lock a roll off container onto the hoist. The movable plate reverts to the unlocked position upon removal of the surface so that the plate moves into the guide.

A method and an arrangement for optimizing load position in relation to a transportation vehicle, comprising a platform arranged to the transportation vehicle for receiving a load; an actuating device for moving the platform in relation to the transportation vehicle; a sensing device configured to generate a vehicle sensing signal and/or a non-vehicle sensing signal; a controlling device configured to receive at least one of the vehicle sensing signal and the non-vehicle sensing signal; generate controlling commands based on the received at least one of the vehicle sensing signal and the non-vehicle sensing signal; and transmit the controlling commands to the actuating device; wherein the actuating device is configured to receive the controlling commands and to move the platform in relation to the transportation vehicle based on the controlling commands.

Methods and systems are provided for loading and unloading an item onto a vehicle. In one embodiment, a system includes: a loading system configured to receive a locker configured to store the item; a shuttle transfer system configured to transfer the locker to a storage position within the vehicle; and a swing arm system that couples to the loading system and the shuttle transfer system, the swing arm system configured to adjust a position of the loading system relative to the vehicle.
