Development of Atlas Copco Hydraulic Rock Drill
Atlas Copco company since 1973 launched the first generation of hydraulic rock drill, continuous improvement, and constantly introduce new models. For example, the date of introduction of the main models of hydraulic rock drills for level roadway tunneling is shown in Table 1.
Table1The age of introduction of the main models of hydraulic rock drills for flat roadway excavation
| Launch year | Model | Impact powerkW | Impact frequencyHz |
| 1973 | COP1038HD | 12 | 42-60 |
| 1983 | COP1238ME | 12 | 42-60 |
| 1986 | COP1440 | 21 | 70 |
| 1992 | COP1838ME | 18 | 60 |
| 2000 | COP1838HF | 22 | 73 |
| 2004 | COP3038 | 30 | 102 |
| 2005 | COP1132 | 11 | 100 |
The introduction of new models does not all mean the elimination of existing models. For example, COP1238 was introduced in 1983 and has been in production for 20 years, during which many new models were introduced; of course, for more than 20 years, COP1238 technological improvements have been ongoing. The new model is launched for two reasons, both of which work at the same time:

(1)One reason for the introduction of new models is to meet the needs of different rock drilling conditions and different rock drilling processes, such,Model for flat roadway tunneling,Model for underground deep hole mining,Model for drilling open bench,Wait.
(2)Another reason for the introduction of new models is because of technological advances, suchCOP1238replacedCOP1038,COP1038No longer in production.,2005launched inCOP1132replaced.COP1032.
