A brief development history of hydraulic drilling machinery and equipment

1. A brief development history of hydraulic drilling machinery and equipment

1)In the middle of 1950s, manufacturers of drilling machinery began to apply hydraulic technology to the control system of drill rigs.

2)By the early 1960s in industrially developed countries, , drill rigs have gradually become main equipment in mechanized drilling projects.

3)In the early 1970s, the invention of hydraulic rock drills led to the emergence of fully hydraulic drill rigs, which elevated drilling technology to a new stage of development.

4)In the middle of 1980s, there were about 30 manufacturers of drilling machinery in the world that introduced to the market nearly 100 models of hydraulic drill rigs and dozens of hydraulic rock drills.

At present, fully hydraulic drill rigs have been widely used for tunneling, mining, rock bolting, and quarrying in infrastructure construction, tunnels of highway and railway, slope support, large and medium surface and underground mines, quarries, hydropower projects, water conservancy, national defense, etc. With the development of drilling and blasting technology, drill rigs are increasingly showing their superiority in construction.
