55 DR

The Woltman 55 DR drilling-rig is engineered for deep foundation construction, delivering exceptional performance across demanding geotechnical applications. This machine combines a substantial 57,000 kg operating weight with a powerful 350 kW engine, establishing a foundation of mechanical strength and operational stability. The architecture prioritizes balanced weight distribution, enabling consistent drilling performance across varied soil compositions while maintaining superior operator control and job site safety. The Woltman 55 DR specifications highlight its technical prowess: 250 kNm maximum torque output and 23-meter drilling capacity make this rig ideal for pile installation, caisson construction, and deep underground work. The powerful drivetrain delivers sustained force for penetrating dense materials and adapting to unexpected subsurface conditions without performance compromise. This capability-to-weight ratio positions the Woltman 55 DR as a cost-effective solution for contractors managing capital equipment ROI across multiple project cycles. Designed for commercial and industrial infrastructure projects, the Woltman 55 DR accommodates diverse drilling methodologies and attachment configurations, reducing equipment changeover time and operational complexity. Its integrated design reduces maintenance intervals while delivering the production rates required by modern foundation contractors, making it a reliable asset for long-term project portfolios.
