Descripción
The self-propelled Minnich concrete barrier wall drill, driven by two pneumatic motors, travels to each section straddling and riding along the top of the temporary wall. While on the non-traffic side of the barrier, the operator uses a tethered controller to simultaneously drill three pin holes through pre-molded holes in the wall, through the road, and into the sub-base to allow steel pins to anchor the barrier wall in place. An optional dust collection system is also available for this drilling unit.
