Abstract: A convertible interlocking cable track system for receiving and handling a flexible member for use in a longwall mining operation. The cable track system includes a series of links adapted to retain the flexible member, each of the links including a single pull link adapted to interconnect with adjacent links, wherein the single pull link is configured to cooperate with a cable control member to form an opening for receiving and handling the flexible member. The cable control member comprises either a shaped rod to form a single pull cable track system, or an outer link to convert the single pull link to a twin pull link in order to satisfy certain loading requirements. The cable track system also includes a securing arrangement for securing the cable control member to the single pull link and an interlocking system for joining the series of links to one another.

Abstract: A replaceable tip cable handler having links in a chain with removable and replaceable interlocking tips, wherein flexible members, such as cable and hose, are received between respective sets of interlocking tips. The interlocking tips engage each other at their respective ends via U-shaped extensions to retain the flexible members therebetween. The replaceable tip cable handler allows operators of the mining machines to repair or upgrade the cable handler in minutes by changing the interlocking tips without the expense of replacing links or the complete chain of links.

Abstract: A handrail connector for a pair of longitudinally spaced apart handrails having ends defining openings, the connector including a flexible bar having ends sized to be fitted within opposing openings of the handrails and being adapted to be retained with the openings upon movement of either of the handrails. The flexible bar includes a stop secured at its center and two biasing members placed on opposite sides of the stop. The biasing members provide a pushing force between the stop and each of the handrail ends to center the handrail connector between the handrail ends.

Abstract: A replaceable tip cable handler having links in a chain with removable and replaceable tips, where flexible members, such as cable and hose, are received between respective sets of tips. The replaceable tip cable handler is a center pull towing design that avoids twisting of the cable handler while providing generous strength to protect the flexible members required by longwall mining machines. The replaceable tip cable handler allows operators of the mining machines to repair or upgrade the cable handler in minutes by changing the tips without the expense of replacing links or the complete chain of links. When a tip is broken off of a link, it can be replaced quickly and easily without removing the link or flexible members retained by the link and in turn reduces downtime of the cable handler. The tips on each link are used to retain the flexible members through the use of friction and provide for retention of each of the flexible members to each link.
