A conveyor assembly for raising and feeding debris such as fallen branches from an orchard floor to a processor such as a wood-chipper is provided. The conveyor assembly comprises a body including a floor having a leading end for location adjacent ground level and a trailing end for location above the leading end in use. A ground contact arrangement is located toward the leading end extends beneath the leading end to thereby raise the leading end above ground level. A powered leading feed roller is disposed adjacent the leading end of the floor to direct members from ground on to the floor. A powered, primary infeed roller is located rearward the leading infeed roller and is arranged to move toward and away from the floor to accommodate members between said roller and the floor and urge the members, such as fallen branches rearward for entry into an inlet of the wood-chipper.

A conveyance system includes a conveyance device including a first conveyance mechanism configured to convey freight supplied from a loader, and a second conveyance mechanism configured to convey the freight supplied from the first conveyance mechanism, a weight detection device configured to detect weight of the freight loaded on the second conveyance mechanism, and a control apparatus. The control apparatus includes a first conveyance control unit configured to control the first conveyance mechanism. The first conveyance control unit controls the first conveyance mechanism based on a detection value of the weight detection device.

A stacker-reclaimer apparatus for handling bulk material at a storage site comprising a central tower having a vertical axis; an infeed conveyer; a stacker boom rotatably mounted to the central tower about the vertical axis, the stacker boom receiving the bulk material from the infeed conveyer; a reclaimer boom rotatably mounted to the central tower about the vertical axis; first and second conveyer screws mounted on the reclaimer boom, the first and second conveyer screws extending along first and second longitudinal sides of the reclaimer boom, respectively; a first harrow extending upwardly and angularly away from the first longitudinal side of the reclaimer boom; a second harrow extending upwardly and angularly away from the second longitudinal side of the reclaimer boom; a reclaim hopper, the reclaim hopper receiving bulk material from the reclaimer boom; and an outfeed conveyer, the outfeed conveyer receiving bulk material from the reclaim hopper.

The present disclosure relates to equipment for handling bulk materials. In a particular form, the present disclosure relates to equipment for use in stockpiling grains in a bulk storage system of the type commonly referred to as a bunker, although its application is not so limited. In one aspect, there is provided a mobile stacker and reclaimer combination comprising a mobile stacker, and a mobile reclaimer which is movable independently to the mobile stacker, wherein in use, the mobile reclaimer simultaneously collects a bulk material and feeds this to the mobile stacker.

A lifting apparatus comprises: a base part, a lifting rope, a sheave assembly, a first rotatably mounted sheave, around which the rope passes and from which the rope extends downwardly to a load, a second rotatably mounted sheave and a drive for moving the sheave assembly. The sheave assembly is mounted for pivotal movement relative to the base part about an axis of pivoting spaced from the axis of rotation of the first sheave and coincident with the axis of rotation of the second sheave. During movement of the load relative to the base part, the first sheave is moved by the drive to compensate for that relative movement, the movement of the first sheave being such that the vertical component of the movement of the first sheave relative to the load is less than the vertical component of the movement of the base part relative to the load.

A stockyard joint reclaiming system includes an outer output conveyor, a scraper reclaimer provided with a scraper mechanism, an inner feeder, and an inner output conveyor arranged below a stockpile. The scraper mechanism includes a chain and a scraper installed on a chain. The chain moves forwards or backwards under the action of a driving device to drive the scraper to push materials to a corresponding discharging port. The scraper mechanism drives the scraper through forward or reverse operation of the chain for pushing the materials to the output conveyor and a reclaiming line can be selected. A reclaiming mode is flexible and more output lines are available. When the material level is lower than a horizontal position, the scraper is driven to move through a reverse operation of the chain to push the materials to an upper part of the inner feeder for realizing reclaiming, thereby reducing unnecessary energy consumption and effectively guaranteeing the reclaiming capability of the scraper reclaimer.

An object processing system is disclosed for unloading objects from a trailer of a tractor trailer. The object processing system includes an engagement system including a truck entry portion for entering the trailer and for indiscriminately engaging unidentified objects within the trailer, and a conveyance system for conveying objects engaged by the engagement system toward an unloading portion of the trailer.
