Sweden Atlas rock drilling rig and drilling machinery (I)
In the late 1940 s, with the rapid development of pneumatic rock drilling machinery, the efficiency of rock drilling production has been continuously improved. However, in order to improve the output power of rock drilling machinery, it is necessary to increase the diameter of the piston, and the weight of the rock drilling machinery is also increasing. Some rock drilling machinery has been completely manipulated manually.
In the late 1940 s, with the rapid development of pneumatic rock drilling machinery, the efficiency of rock drilling production has been continuously improved. However, in order to improve the output power of rock drilling machinery, it is necessary to increase the diameter of the piston, and the weight of the rock drilling machinery is also increasing. Some rock drilling machinery has been completely manipulated manually. In this case, the design concept of the rock drilling rig began to take shape. One or several high-power rock drills, together with the automatic propulsion mechanism, were installed on a special drilling arm, and then the whole device was equipped with a walking mechanism to realize continuous mechanized rock drilling.
