A stackable cargo container apparatus has a frame assembly formed by interconnected structural members, a substantially planar base, interconnecting side walls and at least one personnel access door. At least one lifting harness member of unitary or singular construction is operationally attached to the frame assembly, and permits lifting of the cargo container apparatus from its bottom and away from welds or other possible weak points. An integrated cargo weight measurement assembly permits quick and efficient determination of cargo weight placed on the planar base, and includes a digital display or other output device.

A container for the transport and storage of goods includes an internal fillable tank and an external support structure surrounding the tank. The external support structure has a base structure arranged below the tank, such that a base of the tank is supported on the base structure. The external support structure also has an upper support structure arranged above the tank for absorbing loads exerted on the tank from above. The base structure includes a plurality of lower column portions, and the upper support structure includes a plurality of corresponding upper column portions, which each project from opposing faces of the base structure and the upper support structure respectively and which meet somewhere along the height of the tank, thereby forming a number of columns for laterally supporting the tank.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

A functional training rig kit includes a box and a plurality of components adapted to fit within the box. At least some of the components and the box include elements by which the components are adapted to be attached to the outside of the box to provide at least one functional training rig attached to the outside of the box.
