Description
- This application claims priority to co-pending U.S. Provisional Patent Application No. 62/295,266, filed on Feb. 15, 2016, the entire contents of which are incorporated herein by reference.
- The present invention relates to a mining shovel, and more specifically, a handle for supporting a dipper on a mining shovel.
- In the mining field, and in other fields in which large volumes of material must be collected and removed from a work site, it is typical to employ industrial machines including a large dipper for shoveling the materials from the work site. Industrial machines, such as rope shovels, draglines, etc., are used to execute digging operations to remove material from, for example, a bank of a mine. Rope shovels typically including a boom, a handle movably coupled to the boom and supporting a digging attachment (e.g., a dipper), and a pulley or boom sheave supported on the boom. The handle supports the dipper while the dipper is removing material from the bank. A hoist rope extends over a portion of the boom sheave and is connected to the dipper to raise and lower the dipper, thereby producing an efficient digging motion to excavate the bank of material.
- In one aspect, the invention provides a handle configured to attach an implement to an industrial machine. The handle includes a first member, a second member, and a third member extending between the first member and the second member. The third member includes a first transition extending toward the first member and a second transition extending toward the second member.
- In another aspect, the invention provides a connecting member of a handle configured to attach a work implement to an industrial machine. The handle includes a first member having a first interior face, and a second member having a second interior face opposite the first interior face. The connecting member includes a third member extending between the first member and the second member. The intersection of the third member with the first interior face is non-orthogonal and the intersection of the third member with the second interior face is non-orthogonal.
- Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
