摘要:
A pallet-truck-compatible load elevator includes a vertical mast and a carriage coupled to the mast for vertical motion of the carriage along the mast. The retractable forks are housed in assemblies connected to the carriage and are beyond the front face of the carriage when in retracted position, such that access to the front face of the carriage is unobstructed to a pallet truck carrying a pallet. Each fork assembly includes an outer fork coupled to a support attached to the carriage and an inner fork coupled to the outer fork, the outer fork being horizontally movable with respect to the carriage and the inner fork being similarly movable with respect to the outer fork to provide telescopic extension and retraction of the fork assemblies.

A suspension stacker crane includes an upper truck frame, a pair of mast units, a transferring device, and an upper base. The upper truck frame includes driving trucks arranged side by side in a travelling direction, and a bogie structure that couples the driving trucks. Each of the pair of mast units is suspended from the bogie structure, and includes a lifting drive motor and a lifting drive transmission. The pair of mast units is arranged side by side in the travelling direction. The transferring device is driven to be lifted or lowered by the lifting drive motor and the lifting drive transmission. The upper base links the pair of mast units.

A loading apparatus, in particular for conveying freight over a road surface and loading it into a transporting vehicle and unloading it therefrom, comprises a basic structure, a loading structure, with a freight holder, and a double-action lifting device between the basic structure and the loading structure. The loading structure here comprises a lifting frame, on which the lifting device acts, and a freight carrier, which is mounted on the lifting frame, via a pull-out guide with a pull-out direction oriented transversely to the lifting direction, and has the freight holder. An undercarriage serving for advancing the loading apparatus over the road surface is part of the freight carrier.

An apparatus for transporting a load onto a raised surface includes: a frame; and rear, middle, and front wheel assemblies coupled to the frame. Each wheel assembly includes: at least one leg, at least one wheel rotatingly coupled to the leg for rollingly supporting the frame, and at least one actuator operatively coupled to the at least one leg. The front wheel assembly is configured to extend forwardly from, and retract rearwardly toward, the frame. The actuators are configured to independently raise and lower the at least one rear, middle, and front wheel. A load support member is located below the frame and moveable between a first position where the centre of gravity of the load is located rearward of an axis defined by the at least one middle wheel, and a second position where the centre of gravity of the load is located forward of the axis.
摘要:
A method is provided for identifying one or more scored candidate objects that may correspond to one or more actual pallets in a gray scale image. The method may comprise: identifying, by a computer, a first plurality of scored candidate objects in the gray scale image; storing, by the computer, a starting list of the first plurality of scored candidate objects, wherein the starting list includes a respective record for each of the first plurality of scored candidate objects that includes a respective location of the scored candidate object within the gray scale image, and a respective composite object score that represents a likelihood that the scored candidate object corresponds to an actual pallet structure in the gray scale image; and removing from the starting list each of the first plurality of scored candidate objects which: a) is located within a predetermined vertical distance of a particular one of the first plurality of scored candidate objects; and b) has a respective composite score less than that of the particular one scored candidate object.

A materials handling vehicle is provided including a vehicle power unit, a monomast coupled to the vehicle power unit, and a fork carriage apparatus supported on the monomast. The fork carriage apparatus includes a mast carriage assembly directly coupled to the monomast for vertical movement, a fork carriage mechanism to which forks are mounted, and a reach mechanism coupled to the mast carriage assembly and to the fork carriage mechanism for actuating the fork carriage mechanism to move between an extended position and a retracted position.

A materials handling vehicle includes a power unit, a mast assembly coupled to the power unit, and a reach assembly coupled for vertical movement on the mast assembly. The mast assembly includes first, second, and third weldments, wherein the first weldment is fixed to the power unit, the second weldment is movable with respect to the first weldment, and the third weldment is movable with respect to the first and second weldments. The reach assembly includes an extension/retraction mechanism for effecting horizontal movement of the reach assembly relative to the mast assembly. Components of the vehicle have been redesigned and/or rearranged to improve operator visibility.
