A collector assembly. More particularly, a collector assembly for attachment to a construction machine for collecting broken debris from opposite sides of a member.
Collector assemblies are known in the art for connecting to construction machines, such as cranes or bulldozers, for moving and collecting debris. One such collector assembly is disclosed in U.S. Pat. No. 7,429,158, published on Sep. 30, 2008 to David L. McFarland. The collector assembly includes a center bucket and a pair of extensions that are slideably connected to opposing sides of the center bucket for expanding an operational width of the center bucket. Although such conventional collector assemblies are useful for moving debris after it has fallen to a ground, an issue is that they are not suitable for collecting debris during construction and demolition operations that take place on elevated work surfaces, such as during refinishing or demolition of a bridge. Accordingly, there are often safety and public access concerns during such operations because a large region beneath and around the elevated work surface has to be kept clear from the public. Accordingly, there remains a need for improvements to collector assemblies.
It is an aspect of the present disclosure to provide a debris collecting assembly that is configured to efficiently collect debris during a construction or demolition operation on an elevated work surface.
It is another aspect of the present disclosure to provide a debris collecting assembly that is configured to collect debris during the removal of the debris from an elevated member such as a beam.
It is another aspect of the present disclosure to provide a debris collecting assembly that is simple in design and inexpensive to manufacture.
In accordance with the above and other aspects of the disclosure, a collector assembly is provided for collecting debris from opposite sides of a member. The collector assembly includes a platform extending laterally between a first side edge and a second side edge. A first trough is provided for disposition along one side of the member for receiving debris. A second trough is provided for disposition along the opposite side of the member and is adjacent to and parallel with the first trough.
According to the above and other aspects of the disclosure, the troughs of the collector assembly may be positioned on opposite sides of, and below a member for collecting debris that has fallen from the member or surrounding objects. The troughs eliminate the risk of debris falling from either side of the member while the debris is being removed from the member. Once the debris is collected, the collector assembly can be lifted and rotated using a crane so as to remove the debris from the troughs into waste containers for removal from a work site.
Other aspects of the present disclosure will become better understood by reference to the following description when considered in connection with the accompanying drawings wherein:
Detailed aspects of the present disclosure are provided herein; however, it is to be understood that the disclosed aspects are merely exemplary and may be embodied in various and alternative forms. It is not intended that these aspects illustrate and describe all possible forms of the disclosure. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. As those of ordinary skill in the art will understand, various features of the present disclosure as illustrated and described with reference to any of the Figures may be combined with features illustrated in one or more other Figures to produce examples of the present disclosure that are not explicitly illustrated or described. The combinations of features illustrated provide representative examples for typical applications. However, various combinations and modifications of the features consistent with the teachings of the present disclosure may be desired for particular applications or implementations. Additionally, the features and various implementing embodiments may be combined to form further examples of the disclosure.
Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a collector assembly 20 is generally shown for attaching to a construction machine, such as crane. The collector assembly 20 is used to collect broken debris from opposite sides of, and below an elevated member 21 during a construction or demolition operation in which materials are removed from the member 21. In the example embodiment, the member 21 is presented as a beam 21 of a bridge which is being refinished, however it should be appreciated that the subject collector assembly 20 could be used during other types of operations and with other types of members.
The assembly 20 includes a platform 22, which may have a generally rectangular shape that extends laterally between a first side edge 24 and a second side edge 26. The platform 22 includes an upper surface 28 and a lower surface 30 facing opposite directions. The platform 22 may also include a front wall 23 and a rear wall 25 that extend between the first and second side edges 24, 26 in generally parallel relationship with one another. The front and rear faces 23, 25 may define a cut out 32, spaced equidistantly between the side edges 24, 26, for disposition over the member 21.
A connector 34 is attached to the upper surface 28 of the platform 22 for connecting the collector assembly 20 to the crane. The connector may be attached to the platform 22 in various ways including, but not limited to, welding, molding and fastening. The connector 34 extends transversely and upwardly from the upper surface 28 of the platform 22 and may be attached equidistantly between the side edges 24, 26.

Angular and linear movement of the second deflector 64 may be provided by various actuating mechanisms including, but not limited to, a hydraulic cylinder or electric motor.
A second slide mechanism 66 is disposed on the second rear end 58 and attaches the second trough 52, in a cantilevered fashion, to the lower surface 30. The second slide mechanism 66 facilitates lateral movement of the second trough 52 across the lower surface 30 of the platform 22 between the cut out 32 and the second side edge 26. The second slide mechanism 66 includes a second actuator 67 for providing the lateral movement of the second tough 52 toward and away from the first trough 36. The second actuator 67 may include various types of actuators including, but not limited to a hydraulic piston or electric motor. The second actuator 67 is electrically connected to the controller 53 for selectively activating the second actuator 67. The second slide mechanism 66 further includes a pair of second tracks 69 defined by the front and rear walls 23, 25 adjacent to the second side edge 26. The second slide mechanism 66 also includes a pair of second sliding members 71 that each extend from the second trough 52 are received by one of the second tracks 69 for facilitating the lateral movement of the second trough 52. It should be appreciated that other mechanisms may be utilized to facilitate lateral movement of the second trough 52.
During operation, the collector assembly 20 is attached to the end of the machine using the connector 34. The machine lowers the collector assembly 20 downwardly until the troughs 36, 52 are positioned on opposite sides of, and below the member 21 with the cut out 32 being aligned centrally with the member 21. The machine may lower the collector assembly 20 until the platform 22 comes into contact with or is positioned adjacent to the member 21. After the troughs 36, 52 are positioned on opposite sides of, and below the member 21, they may be moved toward one another until the deflectors 48, 64 come into contact with, or are positioned adjacent to the member 21, as best illustrated in
It should be appreciated that the simple construction of the collector assembly 20 makes it easy and inexpensive to manufacture. Furthermore, it should be appreciated that the simple arrangement of the collector assembly 20 allows it to be connected to various machines of different sizes.
