A bulk tank trailer including an interior storage compartment, at least one straight rear wheel axle supporting a plurality of ground-engaging wheels and a longitudinally aligned discharge pipe in operative communication with the interior storage compartment is disclosed. The entire discharge pipe may be positioned above a transverse plane of the at least one straight rear wheel axle. A method of discharging particulate materials is also disclosed. The method includes filling an interior storage compartment on a bulk tank trailer with the particulate materials, positioning a straight discharge pipe above a straight rear wheel axle on the bulk tank trailer, moving the particulate materials from the interior storage compartment along the straight discharge pipe and discharging the particulate materials from the discharge pipe.

A tank and a method of holding a load and discharging a load therefrom. The tank includes a body having a first wall that bounds and defines a first compartment for holding a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.

A transport trailer and method specifically adapted for safely transporting liquid containing unstabilized drilling waste from more than one waste generator or, multiple waste streams from one or more waste generators. Typically drilling waste is stabilized using binding agents like fly-ash, liquids absorbing pellets or sawdust. In many jurisdictions binding agents are required to stabilize the drill cuttings prior to transport. A sealed transport trailer comprising greater than one container on the transport trailer is described herein which is specifically designed, sized and positioned over a set of axles so as to provide for safe, non-spilling transport, and particular ease of emptying for unstabilized drilling waste.

The present invention relates to a power-driven land, water or air vehicle for providing dialysis solution receptacles, in particular bags, filled with dialysis solution, with the vehicle having a tank for receiving dialysis solution or for receiving a component of a dialysis solution, a storage region for the dialysis solution receptacles to be filled, and a filling station that is in fluid communication with the tank and that is configured to fill the dialysis solution receptacles with dialysis solution or with a component of the dialysis solution.

The invention relates to a device (07) for receiving and transporting components, in particular pipes or tubes (15), on a vehicle (01). The vehicle (01) carries a container (03) having a container cover (05) that is tiltable about a cover axis (19). A carrier (12) of the device is mountable on the container cover (05). An adjustment drive (22) that can pivot the carrier (12) about a pivot axis (21) between a transport position and a working position is preferably also present. Also provided are a retaining device (13) for accommodating at least one component (15), and a drive unit for moving the retaining device (13) relative to the carrier (12) between an upper holding position and a lower removal position. The invention further relates to a suction excavator (01) having a material collection container (03) that includes such a device for receiving and transporting pipes.
