A roller platform apparatus includes a rigid plate, a set of bearings mounted on the rigid plate, and a set of one or more bars attached to the rigid plate. The set of bars is configured to restrict movement of a load into a space between the set of bearings and lower than the height of the one of more bars, and the height of the one or more bars is lower than the height of the first set of bearings and higher than the rigid plate. At least one advantage in this approach is that an equipment rack can be transported without the use of casters that are permanently attached to the equipment rack.

A bulk material shipping container including a pallet, a compartment mounted on the pallet, a material unloading assembly, and a material loading assembly.

A container transport system and method of operation can include: providing a vehicle having a subframe assembly coupled thereto, the subframe assembly including a lifting arm and a clamping arm; clamping the clamping arm onto a corner fitting of a cargo container; raising the lifting arm for raising a portion of the cargo container; inserting a jack stand below the cargo container; lowering the lifting arm for tilting the cargo container on the jack stand, the jack stand configured as a fulcrum; positioning a container trailer below the cargo container; and raising the lifting arm for pivoting the cargo container on the jack stand and lowering the cargo container onto the container trailer.

An Adjustable Lift Bar System for roll off containers and other applications used to enable a roll off to be compatible with a lift bar hoist system set at various heights; the system consists of a lift bar having a crown; a pair of lift bar flanges and mounting flanges with a set of holes to receive removable fasteners and mounting flanges; a long spreader tube between the mounting flanges; a pair of short spreader tubes, bolt plates with a series of holes, the pair of vertical supports, and fasteners to adjustably secure the pair of the mounting flanges of the lift bar assembly to the pair of the bolt plates.

A logistics apparatus for transporting frac sand, frac liquid, and/or drill cuttings between a terminal and a well pad. The apparatus includes a container having a top and bottom. The top having one or more inlet port for receiving frac sand and a liquid outlet. The inlet orts can be secured by watertight covers. The bottom of the container is configured as a hopper having an opening secured by a railcar gate. The apparatus, in position having the railcar gate at bottom, can be used to store and transport frac sand. The apparatus can be inverted for transporting the frac liquid.

An auxiliary convey mechanism for goods in a vehicle compartment, comprising a plurality of splice plates, a plurality of surface boards, a plurality of support frames, a plurality of conveying assemblies and a plurality of avoidance gaps. Each of the conveying assemblies comprises a lifting frame and rollers. Avoidance gaps are formed between two adjacent support frames of the support frames along a length direction of a surface board of the surface boards. Each of the conveying assemblies is disposed in each of the support frames, and each of the surface boards is bent along a width direction of the surface board to have a corrugated shape. The auxiliary convey mechanism for goods in the vehicle compartment has higher structural stability while without occupying the transport space of a truck.

A bulk fluid storage container includes a frame assembly having a lower rectangular frame, first and second wheel assemblies extending from opposite ends of the lower rectangular frame, and an upper rectangular frame member arranged in spaced relation to the lower rectangular frame member by a plurality of vertically extending posts. The bulk fluid storage container also includes a fluid storage vessel having first and second end walls held in spaced relation by first and second side walls, a top wall and a bottom wall, which defines a fluid storage volume. A baffle assembly having a plurality of baffle plates is disposed in a space relationship in the fluid storage volume. The frame assembly provides an exoskeletal structure which surrounds the fluid storage vessel and is configured to support a second bulk fluid storage container in a vertically stacked relationship.

A self-loading container with specific improvements upon prior art. The aim is to expand self-loading from industrial multi mode shipping units to less costly end uses with a range of container sizes, shapes and customizations that perform common tasks and that can be self-loaded into any size vehicle. Gravitational stability is improved by relocating the main rolling means of container from the bottom of vertically extendable jacks or legs to horizontally extendable support rails directly under container. As such, extendable legs are used only to vertically level container with a receiving surface onto which it can then be horizontally transferred by means of its horizontally extendable support rails. Cost and operating improvements include a simplified coupling mechanism torqued for heavy loads with which front and rear leg extension and retraction can be either in pairs, combined or locked.

An industrial sized receptacle or bedding box for industrial fill material which is formed by a distal plate, a proximal plate, two side plates, and a bottom plate. The bedding box is equipped with a means for engagement by a secondary device, such as the bucket of an excavator or similar heavy machinery. The bedding box can then be manipulated by the secondary device to lift and tilt the bedding box to empty the contents of the bedding box through an opening in the proximal plate.

A system for transporting a proppant for fracking may include a transport vehicle, a proppant container, a container clutch part, and a floating clutch part. The transport vehicle may include a carriage having forks for engaging fork pockets of the proppant container. The proppant container may house proppant releasable using a release gate and actuator. The container clutch part may be connected to the proppant container and configured to transfer rotational movement to the actuator. The floating clutch part may be connected to the carriage of the transport vehicle and configured to engage and selectively rotate the container clutch part when the forks engage the fork pockets. The forks and fork pockets vary in size which leads to a potential for misalignment between the container and floating clutch parts. The floating clutch part is vertically and laterally positionable to compensate for misalignments between the container and floating clutch parts.
