A bulk material shipping container trailer includes a base structure, a container support assembly, and a gate moving assembly positioned between the base structure and a container loaded onto the trailer, to enable material in the container to be unloaded from the container through the gate moving assembly and the base structure.

A hopper door opening and closing apparatus operates a door on a hopper discharge opening. A pair of motorized linear actuators, each having an extendable rod, are mounted to support rails on opposite sides of the door. A bracket connects the rods to the door. A controller selectively activates the linear actuators to extend the rods and thereby move the door to an open position that permits material to flow through the lower opening and selectively activates the linear actuators to retract rods and thereby move the door to a closed position covering the lower opening.

A dry-bulk tanker for the provision of binding agent for soil stabilization for a spreading device, comprising a storage container (10) for binding agent. An intermediate chamber (20) is connected to the storage container and is also connected to a compression chamber (40). A conveying device (22) for conveying of binding agent into the compression chamber (40) is arranged in the intermediate chamber (20). A conveying channel (44) is connected to the compression chamber (40). The conveying channel (44) can be connected to a spreading device (58). Furthermore, a pneumatic line (46) for feeding of conveying compressed air is connected to the compression chamber (40) and/or the conveying channel (44).

A dry bulk tank and a method of carrying a load and discharging a load therefrom. The dry bulk tank includes a tank assembly having a first wall that bounds and defines a first compartment for carrying 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 a 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.
