1. Dual rotary motor
The KW600 multipurpose geothermal water well drilling rig adopts two straight gear reducer driven by hydraulic motor from international famous brand with simple structure and reliable performance.
2. Combined positioner
The rig adopts combined positioner. To ensure accurate positioning, the positioning parts can be adjusted and changed according to the types of drill pipe and downhole hammer.
3. Longhole axial compression control system
The unique longhole axial compression control system can adjust the propulsion reasonably, reduce the steering resistance during deep well drilling and improve drilling efficiency.
4. Two stage telescopic carriage
By adopting the two stage telescopic carriage, the drill pipe adopted can be 4.5m without extension of the carriage length. And the times of pipe extension can be reduced and the working efficiency can be improved.
