Brief Introduction:
The YT29A is an advanced heavy-duty Air-leg rock drill. With an enlarged cylinder diameter and corresponding optimized redesign, it works with more output energy, high impact power and fast drilling speed, while at lower air consumption. It can achieve an optimum matching of the impact energy and the percussion frequency, which reduces the vibration to make the operation more stable and comfortable. An improved superior lubrication system ensures a prolonged, endurable and trouble-free drilling work. It is an upgrade and update Airleg rock drill, obtaining enhanced productivity, a mostly ideal mining tool for fast drilling blasthole.
Rock drills can be attached to drilling rigs for jobs when it's necessary to drill very deeply. They can also be manually
controlled by an operator, in the form of a pneumatic rock drill with a throttle. In both cases, people must wear appropriate eye,
ear, and facial protection when working around the drill. These drills are noisy, and inhaling rock dust or getting it in the eyes
can be very uncomfortable. Drilling teams and personnel in the area usually wear facial screens and ear plugs to limit injuries
associated with their work.
