A self-funneling flexible container may be used with a storage and transportation system to provide an efficient, effective and cost-efficient transfer of material to, from or about a site, for example, a hydrocarbon exploration, recovery, production or operation site. The self-funneling flexible container may comprise one or more bands about the bottom or the bottom and one or more sides of the self-funneling flexible container. The bands have an elasticity such that the weight of material disposed in the self-funneling flexible container transitions the bands to an expanded position. When the material is discharged, the bands transition to a contracted position to form a funnel or chute so that all material may be efficiently discharged. As the funnel or chute is only formed at discharge, the self-funneling flexible container may store more material than traditional rigid containers.

A strap protector that includes a first member having a first castellated edge, a ramp sloping down and away from the first castellated edge, and a first securing member extending from one inner wall towards an opposite inner wall, forming a strap opening between the ramp and the first securing member configured to receive a strap. The strap protector also includes a second member having a second castellated edge, a ramp sloping down and away from the second castellated edge, and a second securing member extending from one inner wall towards an opposite inner wall, forming a strap opening between the ramp and the second securing member configured to receive the strap. The strap protector also includes a pin disposed through the first and second members to pivotally connect the first member to the second member.

A freight vehicle has a cargo space that is convertible for handling piece goods and is also suitable for hauling liquid bulk material. A conventional cargo space is equipped with a drop-down frame and flexible liquid enclosure that is stowed in the ceiling of the trailer while hauling a full load of palletized or piece goods materials that can be lowered to the floor for transporting liquid bulk loads. Generally, the long tubular (round and or oval in shape from an end view) can be fitted with a polyethylene film disposable liner. The disposable poly liner will ensure the liquid freight is free from contamination. This concept not only eliminates the need for a liquid tanker to be washed out between each load but also allows for the hauling of piece goods freight when the frame system is raised back to the ceiling.
