The Mait India HR 800 THD Rotary Drilling Piling Rig is a heavy-duty, high-capacity machine engineered for deep foundation projects demanding large bore diameters and extended casing lengths. Equipped with the THD (crowd winch) system, it allows for a longer stroke by raising the rotary higher on the mast—making it ideal for working with long casing sections beneath the rotary. With a maximum nominal torque of 800 kNm and compatibility with the MAIT Casing System (MCS) or torque multiplier, it handles casing insertion and extraction up to 3000 mm in diameter. The HR 800 THD supports multiple drilling technologies including Kelly bar, Casing Oscillators, CFA, diaphragm walls, and driven piles with hydraulic hammers. It’s the ultimate piling rig for dams, bridges, high-rises, ports, and metro infrastructure, where precision and power
