A system for using a heated portable vacuum slurry box to efficiently store and transport material including drill cuttings from gas and oil well sites. 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 features allow for the slurry box to meet space restriction requirements at a well site while functioning within the environmental conditions of winter and summer seasons. The system includes a preferred method to unload the slurry box.

A heated portable vacuum slurry box for efficiently storing and transporting material including drill cuttings from gas and oil well sites. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The features allow for the slurry box to be meet space restriction requirements at a well site while as well as function within the environmental conditions of winter and summer seasons. Jacketed openings, stack mount systems, and a removable power unit allow for efficient use of the slurry box.

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.

The invention relates to a transport vehicle designed preferably for producing a mixture of waste lubricating oils/fuel oil (ALR/FO), mounted preferably on a chassis and comprising at least one metal tank. The metal tank is divided internally into at least two compartments having respective wave-breaks, wherein each compartment comprises a pump system, a plurality of lines for recharging products, at least one quick-filling system for respective FO and ALR compartments, at least one manual traditional filling system, and the vehicle comprises at least one logical control system having at least one actuating panel, at least one actuating reel for the actuation of at least one hose, and at least one static mixer for the ALR/FO mixture having an overpressure safety system, wherein said safety system includes a recirculation system to the ALR compartment, a plurality of double-acting vent valves, at least one man access, at least one battery, a plurality of filters for the suction of recycled oils and at least two filters for direct supply to manufacturing equipment. The invention also relates to an associated process.

A tank trailer may include a plurality of hoppers and a tension bar assembly extending between the hoppers.

An emergency response barrier is shown and described, the barrier having a cab and engine for propelling the barrier; a frame with reinforcing bracing; two axles coupled to the frame with wheels attached thereto; wherein the frame is covered with a substantially planar skin that extends along the right and left sides of the frame, from a top of the frame down to a lower edge and covers a majority of the wheels on each side of the barrier; an impact attenuator coupling on the frame, having a vertical pin received in a bore disposed on an impact attenuator, and configured for rotation about the vertical axis of the pin; and a hydraulic cylinder connected between the frame and the impact attenuator, wherein retraction and extension of the hydraulic cylinder moves the impact attenuator through an arc of rotation about the vertical pin.

A fluid-driven hatch for a bulk material container includes a cover is opened by a fluid-driven cover actuator and secured by a fluid-driven lock actuator. A fluid conduit connects both the fluid-driven cover actuator and the fluid-driven lock actuator to a pressurized fluid source. Pressurized fluid is selectively supplied to the fluid conduit such that the fluid-driven lock actuator is actuated at a first pressure to unlock the cover, and the fluid-driven cover actuator is actuated moments later at a second, higher pressure to open the cover.

A cylindrical cargo container is formed of longitudinal, extruded arcuate panels joined pairwise at abutting edges to form a cylindrical tube. The container is mountable on a separate wheeled chassis to form a semi-trailer or railcar, or a chassis integral with a truck. The container may be substantially smooth on inner and outer surfaces, to provide optimal aerodynamics and freedom of motion of cargo within the container. The panels may have inner and outer skins bridged by multiple webs. Such structure may provide protection from punctures to the outer or inner skins. The container is useful to transport waste including municipal or industrial waste, and may be part of a tipper trailer. The container, trailer, truck, or railcar may be used with a compactor for compacting the waste within the 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.

A ground-level access operating system for a tank trailer. The ground-level system includes a cleaning/washing device, a venting device, an inspection access port, and device for loading/unloading the compartments. All devices in this system are located on the side of the semi-trailer, within an operator's reach on the ground. The devices locations are meant to be reachable to ensure operator safety. The operator of the trailer can execute all work without having to reach the top of the tank. Both of venting and cleaning/washing devices have their access port on top of the tank but are hooked up at a position proximate ground level, for an easy-to-reach operation and inspection by on operator on the ground.
