mining jack hammers

The weight of the hand-held rock drill is relatively light, generally below 25kg, and it is operated by hand when working. A variety of small diameter and shallow holes can be drilled, generally only down holes and near-horizontal holes. Because it relies on manual operation, high labor intensity, small impact energy and torque, and slow rock drilling speed, it is rarely used in underground mines now. Rock drills belonging to this category include models such as Y3 and Y26.

The air-leg rock drill is installed on the air leg for operation, and the air leg can play the role of support and propulsion, which reduces the labor intensity of the operator, and the rock drilling efficiency is higher than the former. The drilling depth is 2-5m and the diameter is 34- 42mm horizontal or with a certain inclination of the blasthole, which is widely used in mines. Such as YT23, YT24, YT28, YTP28 and other models are such rock drills.
