Watertec 40 Water Well Drilling Rig
The Watertec 40 water well drilling rig has been designed for drilling large diameter boreholes to great depths in some of the world’s most challenging environments.
A hugely successful deep water well drilling rig, the Watertec 40 has a lifting capacity of 40,000kgf, and the rig is favoured by large aid agencies, government departments and private contractors for deep borehole drilling projects worldwide.
Capable of most common water well drilling methods including conventional mud drilling and DTH hammer drilling, this model is also used for flooded reverse circulation drilling when the geology demands it, or when very large diameter boreholes are required.
Features include:
- Pullback of 40,000 kgf
- Capable of mud rotary, air and flooded reverse drilling
- Various mounting options including 6×6 or 8×8 truck, or customer own support vehicle or structure
- High torque rotary head with hydraulic side shift and head tilt
- High pressure air/water swivel
- Main winch for tools and casing
- Auxiliary winch for tool handling
- Selection of on-board air compressors
- Selection of on-board mud pumps
- Can be supplied with complete tooling packages
- Onsite training available from Dando drilling engineers
