Drilling Long Tom - MacLean Engineering - #2

Features

• A cost effective solution that eliminates or reduces the following negative aspects of handheld drilling in trackless areas:

- Hard physical labour on uneven terrain

- High injury frequency, especially strains

- Low productivity with inexperienced crews

- Reduced pull due to hole misalignment

• The LongTom drilling system mounted on a rubber-tired mine carrier solves all the above problems and offers low maintenance costs, safe operation and increased drilling achievement per manshift

• Rail mounted systems on application
