Woltman is a specialist when it comes to foundation equipment. The state of the art Woltman Piling & Drilling rigs are sophisticated and yet easy to operate in restricted and urban surroundings. The rigs can be delivered in many different versions and if necessary customized to the customer’s needs. All machines have access to a powerful engine and hydraulic system. This makes it possible to power an impact- or vibratory hammer or rotary head directly by the system of the machine without the need of an additional power pack. Woltman primarily uses Caterpillar engines combined with Bosch-Rexroth hydraulics. In case more hydraulic power is required a power pack can be mounted on the rear side of the machine. Woltman offers a wide range of machines with leader lengths exceeding 50 meters. Most of the machines are specifically designed for the installation of raked piles.
