The present invention relates, in general, to a material delivery and waste removal trailer and, in particular, to a material delivery and waste removal trailer having a rear extending storage bin.
Workers often find that providing materials for replacement of a building roof is very time consuming, considering the task involves using different mechanical units or manual labor to lift building materials from a truck and position them on a roof. Furthermore, stripping old material from the building roof in order to put on a new roof is also time consuming and a dirty job. Generally, old material is thrown from the roof to the ground around the around the building and then workers manually pick up debris to deposit it into a disposal container. Even if the material can be thrown directly into a container, there remain the problems of getting the disposal container in proximity to the roof and removal from the roof site.
The most common solution to the disposal problem is to move the dump truck adjacent to the building and to attempt to throw the material directly from the roof into the truck bin. Furthermore, the problem is not limited to roofing material. Many building remodeling generate significant construction trash and the most convenient method of removing it from the building is to throw it out a window. It is not always possible to move a large truck into a location adjacent to a building. Fences, lawns, and shrubs can be damaged by the truck, especially a large transport truck.
A material delivery and waste removal trailer, constructed in accordance with the present invention, includes a main frame, a scissors lift mechanism mounted on the main frame, and a storage bin. The storage bin has a frame mounted on the scissors lift and a container mounted to the frame of the storage bin. The container of the storage bin is movable pivotally vertically away the frame of the storage bin and linearly horizontally through the frame of the storage bin. A material delivery and waste removal trailer, constructed in accordance with the present invention, also includes a first hydraulic cylinder that extends between the main frame and the scissors lift mechanism and controls movement of the scissors lift mechanism away from the main frame and toward the main frame. A material delivery and waste removal trailer, constructed in accordance with the present invention, further includes a second hydraulic cylinder that extends between the frame of the storage bin and the container of the storage bin and controls movement of the container of the storage bin away from the frame of the storage bin and toward and the frame of the storage bin. A material delivery and waste removal trailer, constructed in accordance with the present invention, also includes a control system selectively activating and deactivating the first hydraulic cylinder and the second hydraulic cylinder.
A more complete understanding of the present invention may be derived by referring to the detailed description when considered in connection with the accompanying illustrative figures. In the figures, like reference numbers refer to like elements or acts throughout the figure
Referring to the drawings, a material delivery and waste removal trailer, constructed in accordance with the present invention, includes a main frame 20 which has, for the embodiment of the present invention illustrated and being described, support beams 22 and connecting beams 24 extending substantially perpendicular to and connecting the support beams 22. Main frame 20 can have a construction generally similar to frame 10 in U.S. Pat. No. 10,017,091.
A material delivery and waste removal trailer, constructed in accordance with the present invention, also includes a scissors lift mechanism 26, of conventional construction and operation, mounted on main frame 20. Scissors link mechanism 26 has a plurality rigid line segments 26a, 26b, 26c with a number of the rigid line segments pivotally linked together by hinged intersections 26d, 26e.
A material delivery and waste removal trailer, constructed in accordance with the present invention, further includes a storage bin 28 which has a frame 30 mounted on scissors lift 26 and a container 32 mounted to frame 30 of storage bin 28. Container 32 of storage bin 28 is pivotally mounted to frame 30 of storage bin 28 at a first end 30a of frame 30 of storage bin. 28. Container 32 is movable pivotally vertically away frame 30 of storage 28 bin and back to frame 30 of the storage bin as indicated by arrow 34 and linearly horizontally through frame 30 of storage bin 28 as indicated by arrows 36 as shown in
As shown most clearly in
A material delivery and waste removal trailer, constructed in accordance with the present invention, further includes a first hydraulic cylinder 42 extending between main frame 20 and the scissors lift mechanism 26. First hydraulic cylinder 42 controls movement of the scissors lift mechanism away from main frame 20 and toward main frame 20.
A material delivery and waste removal trailer, constructed in accordance with the present invention, further includes a second hydraulic cylinder 44 extending between end 30d of frame 30 of storage bin 30 and container 32 of storage bin 28. Second hydraulic cylinder 44 controls movement of storage bin 28 away from frame 30 of storage bin 28 and toward and frame 30 of storage bin 28.
Control system 46 can be connected physically to first hydraulic cylinder 42 and second hydraulic cylinder 44 to control activation and deactivation of the two hydraulic cylinders or control system 46 can be arranged to activate or deactivate the two hydraulic cylinders wirelessly.
The following describes the various positions a material delivery and waste removal trailer, constructed in accordance with the present invention, can take and the particular functions that can be fulfilled at the various positions.
The foregoing illustrates some of the possibilities for practicing the present invention. Many other embodiments are possible within the scope and spirit of the invention. It is, therefore, intended that the foregoing description be regarded as illustrative rather than limiting, and that the scope of the invention is given by the appended claims together with their full range of equivalents.
