NIOSH Testimony on Automatic Emergency-Parking Brakes for Rubber- Tired, Self-Propelled Electric Face Equipment by L. D. Reed, July 12, 1988.
NIOSH 1988 Jul:3 pages
Testimony was offered in support of the Mine Safety and Health Administration (MSHA) proposal which will force technological developments of automatically activated emergency parking brakes for rubber tired, self propelled electric face equipment. Three areas of concern to NIOSH were emphasized. First, there was no requirement to limit the rate of deceleration when the brakes engage or, alternatively, no full body safety restraints for operators or passengers riding the equipment. Secondly, there was an exemption provided for equipment traveling less than 2.5 miles per hour. The author recommends that MSHA present documentation to support this exemption and that, if warranted, extend the exemption to safety restraints for slow moving vehicles. Thirdly, the proposed rule did not apply to nonelectric powered or nonface equipment and NIOSH would like to have the rule extended to include all self propelled mine equipment. This would include track operated vehicles as well as mantrip and haulage vehicles used by the working face. NIOSH further suggested that the proposed breaking systems be designed to operate mechanically rather than through hydraulic mechanisms.
