Advantages: 1. Fast speed: hydraulic rock drill is used to fully improve drilling efficiency. 2. Flexibility: The excavator-modified drilling rig fully combines the advantages of the excavator's walking convenience and the drilling speed of the drilling rig, and is suitable for drilling operations at different angles under complex working conditions. 3. Simple operation: The operation panel is placed in the excavator's cab, and the excavator can be operated after simple training. 4. Fast rock drilling speed and low energy consumption: the energy consumption of hydraulic rock drills for excavation and modification is only one third of that of the same type of pneumatic equipment.
