A breakthrough in mine safety technology, the Duraguard™ is a mechanically operated face support system designed to counter rockfall problems at the working face. Consisting of two similar steep support units connected to each other via two crank mechanisms, the Duraguard™ can handle stoping widths of 600mm to 1600mm, has a preload force of 50kN per leg, is steerable and can advance in 300mm steps. It is simple to install and maintain and can be integrated with blasting barricades, netting and rock drills.
