Down the hole hammer
A down the hole hammer with a hydraulic rotor positioned between the pile driver hammer and the vertical sliding column can be used to drill in rock, concrete (without reinforcement) or highly compact conglomerates easily and effectively.
The “rotor/down the hole hammer” system can be used as required and released and left in position, ready to use, when it is not required.
This system allows drilling and driving using alternatively a down the hole hammer and the pile driver hammer without having to dismantle any heavy parts, offering the utmost efficiency, safety and ease.
A pile driver on tracks equipped with a bottom hammer can be completed by adding a filter for collection of residual material.
