Description
YT29A rock drill as equipemnt rack is the most rugged, powerful and highly efficient rock drill in the range. It provides improved productivity and drill steel economy and can be used on all rock formations and in various applications.
Equipment
YT29A pusher legs and stoper rock drills cover all construction, tunnelling and mining applications in different rock formations. They are robust designed, with high impact energy and low air consumption. All of the rock drills have water flushing, rifle bar rotation and the pusher leg control is placed at the back head of the rock drill. An in-line lubricator is included in the delivery of each rock drill. Together with the appropriate pusher leg, the rock drill forms an attractive and cost effective drilling unit.
