Introduction
Daily operational inspections are critical for rotary drill rig safety, performance, and reliability. This comprehensive checklist helps operators identify potential issues before they lead to equipment failure, accidents, or costly downtime. By performing these checks at the beginning of each shift, you can ensure your drilling operations proceed safely and efficiently.
Rotary drill rigs are complex pieces of equipment used in construction, mining, water well drilling, and geotechnical applications. Due to the high forces involved and often challenging operating environments, systematic daily inspections are essential to maintain productivity, prevent unexpected failures, and above all, ensure the safety of operators and ground personnel. This checklist aligns with OSHA requirements, manufacturer specifications, and industry best practices for drill rig safety.
Equipment Information
Pro Tips for Effective Drill Rig Inspection
- Perform in Proper Sequence: Complete all visual inspections with the engine off, then operational checks with the engine running, and finally drilling function checks. This structured approach ensures safety and thoroughness.
- Document Discrepancies Immediately: When an issue is found, document it right away with photos if possible. This creates a clear record for maintenance personnel and helps track recurring problems.
- Check Weather Conditions: Consider how current weather might affect drilling operations and adjust inspection focus accordingly (e.g., hydraulic system in cold weather, cooling system in hot weather).
- Validate Safety Systems: Never bypass safety system testing. Emergency stops, guards, and warnings are critical for preventing serious incidents.

Critical Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of your rotary drill rig. These steps are essential for safe and efficient rig operation.
Emergency Stop Testing
- Ensure area is clear of personnel
- Start engine and bring to normal idle
- Activate each E-stop button individually
- Verify engine shuts down immediately for each test
- Reset E-stop after each test
- Document any E-stops that fail to function properly
- Test remote E-stops if equipped
Hydraulic System Check
- Start engine and allow hydraulic oil to warm up
- Set engine to normal operating RPM
- Cycle each hydraulic function through full range
- Check for smooth operation with no jerking
- Listen for unusual noises in pumps or valves
- Verify no cylinder drift when controls in neutral
- Check hydraulic pressure gauges in each function
Mast Raising Procedure
- Check overhead for power lines or obstructions
- Ensure outriggers are properly deployed
- Verify all personnel are clear of mast path
- Slowly raise mast while monitoring alignment
- Watch for any binding or unusual movement
- Check mast lock engagement when fully raised
- Verify mast is plumb using inclinometer
Drill Head Function Test
- With mast raised and secured, test rotation
- Verify smooth rotation at various speeds
- Test head feed up and down full mast length
- Check head traverse mechanism if equipped
- Test head tilt function if equipped
- Verify torque indicator function
- Test all drill head controls for response

Pre-Drilling Safety Guidelines
Before commencing drilling operations, follow these critical safety procedures to ensure a safe working environment for all personnel on site.
Site Assessment
- Verify underground utility clearance
- Check for overhead power lines (maintain min. 20ft distance)
- Assess ground conditions for stability
- Identify and mark potential hazards
- Establish exclusion zones around drill rig
- Verify adequate workspace for rod handling
- Check for environmental concerns (dust, noise)
Personnel Briefing
- Conduct pre-shift safety meeting
- Review emergency procedures and signals
- Confirm all personnel have proper PPE
- Establish clear communication protocols
- Define individual roles and responsibilities
- Review safe approach zones for rig
- Discuss specific hazards for current operation
Rig Positioning
- Position rig on level, stable ground
- Deploy outriggers/stabilizers fully
- Use adequate cribbing under outriggers if needed
- Check rig levelness with inclinometer
- Ensure adequate clearance for mast raising
- Verify safe distance from excavations/trenches
- Establish clear access paths to/from rig
Drilling Tool Inspection
- Inspect all drill rods for damage/wear
- Check bit condition and secure attachment
- Verify all tool joint threads are clean and undamaged
- Ensure tools are properly rated for the job
- Verify handling tools are in good condition
- Inspect all connection points and adapters
- Arrange tools in proper sequence for operation
