Information Circular 9047: Lightweight Fiberglass Feed Leg for Hand-Held Pneumatic Percussion Rock Drills

Details

• Personal Author:
  Spencer, Ellsworth R.
• Description:
  A lightweight fiberglass feed leg for hand-held pneumatic percussion rock drills has been fabricated and tested by the Bureau of Mines. Its lighter weight facilitates easier handling of the rock drill apparatus, thereby reducing the potential for back injury to the driller and increasing drilling productivity. Current hand-held feed leg drills of the same class are 50 pct heavier than the Bureau- devised feed leg drill, which is comprised of a reduced-noise drill and the fiberglass feed leg. In-mine tests of the fiberglass leg showed that its performance and cost are comparable to those of standard aluminum feed legs. [Description provided by NIOSH]
