The drill rig adopts full hydraulic driving, travelling with crawlers itself, with 1500m drilling capacity.
DRILLING DEPTH GUIDELINES
The figures in these tables have been calculated, based on field experiences, and may be reasonably expected.
Actual drilling capacity will depend on in-hold tools and conditions, drilling techniques and equipment used.
