Crawler Mounted Drill Rig Core Essentials for Safe Operation and Efficient Performance
Crawler Mounted Drill Rig Proper operation is directly related to equipment service life and construction safety. Operators must strictly adhere to the following key points.
Pre-Startup Checklist：
Comprehensive Inspection Check hydraulic oil levels, filter conditions, and structural component tightness.
Drilling Assembly Verification Ensure drill rod threads are undamaged and the impactor lubrication system has adequate oil.
Dust Control System Check Inspect the seal integrity of the dust collection filter to maintain optimal dust removal efficiency.
Drilling Phase Control：
1. Initial feed pressure should be low with slow speed. Gradually increase pressure only after the drill bit has made stable contact with the rock face.
2. Monitor pressures of all systems in real-time. Immediately stop and investigate if abnormal fluctuations occur.
3. Record the penetration rate in different rock strata to build a geological database for optimizing drilling parameters.
Key Operational Considerations：
1. Strictly prohibit forcibly raising the drill rod during a stuck drill condition.
2. Pre-emptively adjust impact frequency and rotation speed when encountering complex geology.
3. Clean accumulated dust from the power head guide frame each shift. Check the impactor piston clearance weekly.
Critical Warnings：
1. Borehole deviation exceeding 2% requires immediate correction for Crawler Mounted Drill Rigs.
2. Operation must be stopped for inspection if hydraulic oil temperature consistently exceeds 80°C.
3. Only use specified lubricants for the impactor; non-standard oils are prohibited.
Standardized operation can improve overall equipment effectiveness by over 35%. It is recommended to establish a standardized "Pre-shift Inspection – In-process Monitoring – Post-shift Maintenance" procedure. Utilizing smart terminals to log operational data in real-time enables the implementation of predictive maintenance.
