An abrasive cutting apparatus including a cutting chain formed of pivotally connected links is described for cutting rock, concrete and the like. The abrasive cutting chain is inverted so that its cutter links having abrasive cutting elements fixed thereto face inwardly of the endless loop of chain. A motor driven drive pulley having a groove which may be provided with an elastomer liner, engages the cutter links to drive the chain. A pair of idler pulleys with grooves that engage an outward projection on each of the center links of the chain guide the movement of the chain to provide lateral stability and proper tension to such chain. A releasable connection formed by a pair of connector side links and a connector pin with intermediate portions of reduced diameter, is employed to connect chain sections of standard length to form an endless chain of adjustable length and to enable replacement of broken sections in the field manually without the use of special tools.
Abrasive cutting apparatus, comprising:
Abrasive cutting apparatus for cutting hard material, comprising:
Cutting apparatus in accordance with claim 15 in which the chain includes side links and center links between pairs of side links, which also includes pulley means engaging projections on the center links, which projections extend outwardly of the loop beyond the side links, for tensioning the chain and for guiding the movement of the chain to provide lateral stability to said chain.
