Abstract
A connection link for coupling together the first and second chain links of a tram chain normally used to propel mobile articulating mining conveyors. The first and second tram chain links are hooked through a "U"-shaped member and are captively held in a relatively static position by a retaining member. The ends of the "U"-shaped member are threaded and extend through the retaining member to engage corresponding fastening nuts to thereby enable the retaining member to be separated from the "U"-shaped member. A tram chain crawler pad, similarly adapted to engage the "U"-shaped member, may also serve as a retaining member.
