Woltman offers a wide range of drilling rigs.

Most of these purpose build rigs are especially designed for high torque drilling methods like displacement drilling and big diameter CFA.

No excavator or crawler crane is used as undercarriage which has made it possible to guarantee the highest possible stability and low centre point of gravity. All Woltman rigs have a solid and strong undercarriage which is hydraulically extendable and is fitted with wide track plates. The winches of the Drilling rigs are fully synchronized in pull-up and pull-down operation. Lots of accessories available to enable multipurpose operation.
