A container or pod is specially constructed for hauling proppant in support of oilfield hydraulic fracturing operations. Dimensions are provided that comport with common dimensions in use for transportation of intermodal containers, with the containers being sized so as not to require special permitting from a regulatory standpoint when two such containers are loaded on a single trailer. A method of filling the containers is also provided, which include inverting the container to fill from a bottom gate that also serves as the discharge opening when the filled container is rotated back into an upright position.

A tool for removing a runner from an agricultural bin having a lever arm and a plurality of crossbars. The lever arm may be directly, or indirectly, engaged with a rotatable crossbar which may have a plurality of protrusions for engaging corresponding tabs of a runner. To use the tool, a user may align the protrusions of the rotatable crossbar with the corresponding tabs of a runner engaged within a leg of an agricultural bin, then the user may press down on the lever arm, causing the crossbar to rotate and engage the tabs. As the user continues to press down on the lever arm, the tabs eventually disengage from corresponding openings in the leg of the agricultural bin, allowing the user to remove the runner from the bin.

Embodiments of the present invention include systems for storing large quantities of chemicals at a remote site. A controlled blending system balances the inflow of dry material and liquids into the blender based on a predetermined solid/fluid ratio. The blending system further balances the inflow and outflow of material from the blender.

An improved shock isolating mounting comprising at least three substantially U-shaped leaf spring members, each leaf spring member comprising at least two leafs arranged to define a space therebetween. In one arrangement, the respective at least three substantially U-shaped leaf spring members are arranged in an array having a substantially equal angular spacing between adjacent spring members.

A transportable container includes: a container, wherein the container comprises: two sidewalls; a front wall; and a floor; and a mating assembly, wherein the mating assembly is attached to the container and comprises: two or more rails secured to an underneath plane of the floor, wherein the two or more rails matingly engage with two or more hoist rails of a roll-off truck; two or more rear rollers; and a loading assembly. The mating assembly and the loading assembly can be attached to the container after the container has been transported from a first location to a second location. The container can thus, be re-purposed for loading, transporting, and unloading via a roll-off truck. The container can be loaded, transported, and unloaded via a cable/winch system or a hook/lift system of the roll-off truck.
