Hycon Rock Drill

The HRD28X Underwater includes a newly developed handle, which allows underwater operation, while still getting the benefit of reduced vibration. For top-side use, the HRD28X Underwater uses a spring design which requires the operator to compress the handles.

This is not possible in an underwater environment as a downward press pushes the diver upwards / outwards.

To alleviate this, the new handle has been designed. The handle allows a neutral position for the diver with reduced vibration without being required to press the handle down. 

The HRD28X requires a connected small compressor to supply flushing air.
