Product Description

The Air-Legged Rock Drills represent the pinnacle of heavy-duty, air-legged rock drilling technology. Engineered for low energy consumption, these drills excel in creating horizontal or inclined boreholes in medium-hard to hard rocks (f=8-18). They are versatile enough to drill anchor holes either upwards or downwards.

Adaptable to various roadway section sizes and operating conditions, the YT29A can be paired with FT160A (or FT160B, FT160C) or used on drill trucks and frames for both dry and wet rock drilling.

Operating Guidelines
  • Ensure all parts are intact and well-lubricated before use. Check wind and water pathways.
  • Inspect the roof for loose rocks before starting operations.
  • Ensure the working surface is flat to avoid slippage or displacement.
  • Always drill with water (wet drilling). Start with water first, then air.
  • Operate at low speed initially, then switch to full speed at depth.
  • Do not wear gloves while operating the drill.
  • Maintain correct standing posture; do not pressurize the machine with your body.
