Concrete Barrier Wall Drill from Minnich
At last week's World of Concrete event, Minnich Manufacturing introduced a concrete barrier wall drill, designed to help maximize the efficiency and safety of drilling vertical holes for the pins used to secure temporary concrete traffic barriers. The air-driven, self-propelled drill straddles and rides along the top of the barrier.
Operators use a tethered controller enables the operator to simultaneously drill three accurate, consistent pin holes — through pre-molded holes in the wall, through the road, into the sub-base — while positioned on the non-traffic side of the barrier. The drill can be customized to fit F-shape barriers, Jersey barriers or any other barrier wall profile. The drill spacing and hole depth of the Minnich concrete barrier wall drill are adjustable. The unit can be easily moved with a forklift and loaded onto the wall with a backhoe or service crane.
“We’re excited to introduce the Minnich concrete barrier wall drill — especially with U.S. states moving toward requiring temporary barriers to be pinned,” said Todd Jurjevic, director of sales at Minnich Manufacturing. “The new drill saves contractors significant time and cost and promotes safety by eliminating the need to hand-drill pin holes on the traffic side of the barrier.”
Now a standard Minnich product offering, the concrete barrier wall drill had been a special-application drill. The company says the drill, used on an Illinois project, provided a 35 percent time savings, with nearly a 20 percent labor and equipment cost savings,and approximately 30 percent bit cost savings with a custom Minnich concrete barrier wall drill compared to a three-person crew using high-powered rotary hand drills. Accuracy and consistency of the holes it drills make pin removal easier.
The concrete barrier wall drill also improves operator safety, avoiding the rigors of manual drilling and working on the non-traffic side of the barrier wall. The tethered controller also helps remove the operator from excess dust and debris.
