A bulk material tender is described. The bulk material tender includes a hopper. The hopper includes one or more side walls defining a top opening and a bottom opening. The bulk material may also include a frame connected to and supporting the hopper. The bulk material tender may also include a rotary airlock for receiving material from the hopper. The bulk material tender may also include a pneumatic conveyor coupled to the rotary airlock for conveying the material to a desired location. The bulk material tender may also include a slide gate valve between the rotary airlock and the hopper. The bulk material tender may also include support legs and jacks for self-loading and self-unloading from a vehicle.

A jack stand having a rack-and-pinion gearing mechanism to extend a support member. The jack stand further comprises a latching mechanism suitable to provide a static force operable to sustain elevation of a vehicle. The jack stand further comprises a number of sleeves configured to receive a detachable handle operable to utilize the functions of the jack stand from a distance away from the underside of the vehicle.

A transport vehicle includes a pair of left and right vehicle body frames extending in a front and back direction; driving wheels disposed at a middle portion in the front and back direction of the pair of left and right vehicle body frames; auxiliary wheels disposed at a lower portion of an end portion in the front and back direction of each of the right and left vehicle body frames; lifter mechanisms disposed at an upper portion of an end portion in the front and back direction of each of the right and left vehicle body frames; a connection frame connecting upper portions of the right and left vehicle body frames to each other; and a lower frame disposable between the right and left vehicle body frames, the lower frame being removably fixed at lower portions of the right and left vehicle body frames.

A measurement system that comprises at least one horizontal load measuring unit, that is preferably arranged on the leg guide is provided. The horizontal load measuring device measures or determines horizontal load on the position of the leg where the device is placed, which gives a more accurate indication of the leg bending moment than the rack phase differential measurement. Advantageously, multiple load measuring units can be provided along the leg guide.

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.
