Abstract: 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.

Abstract: A cooping apparatus by which a large number of chickens, such as may be found growing within a chicken house, are mechanically transferred into a multi-tiered coop. A conveyor is supported along the length of a boom, and a chicken gathering apparatus is supported from the depending end of the boom for gathering the chickens onto the boom conveyor, which moves then onto an elevated intermediate conveyor system. Overlying the conveyor system is a pivotally mounted set of distribution vanes that uniformly distributes the chickens as they continue to move along the conveyor system towards the receiving end of a transfer divider. The transfer divider divides the chickens into a plurality of horizontal parallel paths, each path leading into the compartments of one tier of a multi-tiered coop that is supported on the rear of the machine.

Abstract: An improved gantry crane that has a control cab mounted for vertical up and down movement substantially parallel with respect to the upstanding columns of the crane between a lowermost position adjacent the ground and infinite positions within a fixed range. One or both of the sill beams of the crane include a downwardly offset mid-portion extending adjacent to the ground but spaced therefrom with the mid-portion of one of the sill beams being positioned to receive the control cab when in the lowermost position thereof. A supporting beam supports the control cab therebeneath so that the operator in the cab has a 360 degree substantially unobstructed view in all directions.

Abstract: A container handling apparatus for lifting a container by first and second apertures in opposite sides thereof, comprising: a frame having first and second sides; first and second reciprocating beams mounted to the frame for inward and outward movement with respect thereto, respectively from the first and second sides thereof; first and second inwardly directed pins, respectively attached to clamp heads at the ends of the reciprocating beams, for registered insertion into the container's side apertures; hydraulic cylinders or motor driven screws for reciprocating the beams with respect to the frame between a released condition and a gripping condition; and either a lock wedge operating against a striker plate and aperture or compression washers for causing the reciprocating beams to move inwardly while in the gripping condition so as to track decreases in the width of the container due to bowing as the container is lifted.
