Woltman THW7528D

The Woltman THW7528D was specially developed for screw-pile work involving soil displacement and can be used for in-situ screw piles with lengths of up to approx. 29 m.

Folders were developed for projects that require a short set-up time and/or have limited available set-up space. These pile driving machines are transported in almost complete state, including the equipment for driving or drilling piles.

Folders are generally used for all usual types of pile system: from traditional pre-fab concrete piles to modern in-situ displacing or earth-removing pile systems.

Some machines are suitable for work ‘from the side'.
