ABSTRACT:
A curve-negotiating conveyor particularly for use in underground mining operations wherein the conveyor can be designed to any desired length since it compensates for the extension of the conveyor track occurring over the extended length of the conveyor without the positively operating driving devices becoming disengaged. The conveyor has a track forcibly guided on an undercarriage, the links of the track being flexibly joined to one another and the track resists tension and compression. The undercarriage is comprised of undercarriage segments being flexibly joined to each other and having limited lengthwise displacement. Some of the individual segments of the undercarriage are connected with driver devices having sprocket wheels that positively engage the conveyor track.
