75 DR

The Woltman 75 DR drilleadh-rig is engineered for demanding deep bunús projects requiring exceptional performance and reliability. Weighing 102,000 kg, this heavyweight machine delivers the structural stability essential for challenging soil conditions across diverse geographic and urban environments. Its proven design combines portability with impressive operational capability, making the Woltman 75 DR specifications particularly attractive for bunús contractors seeking a versatile platform that performs equally well on confined city sites and remote project locations. Equipped with a maximum torque output of 350 kNm, the Woltman 75 DR excels in penetrating difficult geological formations while maintaining consistent drilleadh efficiency. The rig achieves drilleadh depths up to 27 meters, enabling comprehensive pile installation and borehole construction for large-scale infrastructure and building projects. Advanced hydraulic technology integrated throughout the system minimizes operational downtime and maximizes site productivity through precision control and sustained power delivery. The Woltman 75 DR specifications include capabilities across multiple drilleadh methodologies—rotary drilleadh and DTH hammer techniques—making it suitable for civil engineering, geotechnical site investigation, and specialized bunús work. Its robust frame construction and hydraulic systems combine to deliver dependable performance in varied applications, from basement construction and underpinning to geotechnical research and structural pile driving operations.
