According to one or more embodiments, a hand-held, portable opener for a hopper trailer and method of opening is described. The hopper trailer opener comprises a base tool assembly coupled with an extension shaft assembly and can be adapted for use with a variety of different trailer opening mechanisms.

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 a 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 control assembly provides autonomous control of various functions of a grain cart and/or provides guidance to an operator of the grain cart during the unloading of a grain cart. The control assembly collects input from one or more sensors including a speed sensor to monitor speed of a PTO that drives the unloading auger of the grain cart, a height sensor that measures the height of material discharged from the grain cart into a receptacle such as a grain truck, and/or a boundary sensors that measure lateral position of the grain cart relative to the receptacle or grain truck. Based on the input, the control assembly may vary the position of the discharge gate of the grain cart, or provide guidance to the operator to steer and position the grain cart relative to an adjacent grain truck.

An assembly for a fracking sand trailer wherein a door can be positioned to allow a measured flow of sand to exit the assembly. The assembly can be attached to a hopper of a trailer and can stand the weight of heavy loads associated with sand. A trailer with the assembly is also described and utilizes specific construction techniques to lighten the weight of the trailer.

A swing auger towable by a tractor features a main auger, and a feed auger pivotally coupled to the main auger and reaching transversely outward therefrom. One or more additional conveyors each are positioned alongside the tractor with the discharge of the conveyor(s) feeding into the feed auger, and with the conveyor hopper positioned longitudinally forward of the tractor under the bottom discharge of the trailer or other source receptacle. A stabilizing device for the main auger doubles as a lift arm for elevating the conveyor in a transport position, and may be installed with a tandem axle that compensates for angular frame variation in the working position of the main auger. Alternatively, a novel auger frame is pivotally coupled to the inlet end of the main auger, remains at a consistent angle regardless of the main auger's position, and is equipped with a hitch connector and rear stabilizer arms.

A dry bulk tank and a method of carrying a load and discharging a load therefrom. The dry bulk tank includes a tank assembly having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. The tank assembly includes an air piping system that is selectively actuated to place the first compartment and the second compartment under a substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.
