Patent ID: 7472502

Claim:
A subassembly system for connecting an excavation mining dump bucket, having a bucket arch, a first drag chain and a second drag chain, a first dump rope and a second dump rope, and a spreader bar subassembly, to a first drag rope, a second drag rope and a hoist rope comprising: a first drag socket, having a first drag socket body, a first frustoconical receiving surface in the first drag socket body and a first support sled member, pivotally connected to the first drag chain; a second drag socket, having a second drag socket body, a second frustoconical receiving surface in the second drag socket body and a second support sled member, pivotally connected to the second drag chain; a first metallic wedge nugget, welded to the first drag rope, adjacent the first frustoconical receiving surface and adapted to removeably connect the first drag socket to the first drag rope; a second metallic nugget, welded to the second drag rope, adjacent the second frustoconical receiving surface and adapted to removeably connect the second drag socket to the second drag rope; a first dump socket pivotally connected to the first drag socket and the first dump rope; a second dump socket pivotally connected to the second drag socket and the second dump rope; a first anchor socket pivotally connected to the bucket arch and to the first dump rope; a second anchor socket pivotally connected to the bucket arch and to the second dump rope; the first dump rope connected to the spreader bar subassembly by a first pulley subassembly; the second dump rope connected to the spreader bar subassembly by a second pulley subassembly; and the hoist rope operably connected to the spreader bar subassembly.
