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. The form and dimension of the tip can be manufactured to retain various sizes and numbers of flexible members allowing current tips attached to a link to be replaced by an upgraded version to accommodate any flexible member configuration changes.
