The Apollo DW 235 Diaphragm Wall Drilling Rig is India’s first indigenously developed diaphragm wall rig, engineered for deep and precise underground construction. Powered by a robust Caterpillar engine, this rig offers a grabbing range of 400 to 800 mm with a drilling depth of up to 30 meters, including Kelly extensions. Its free-fall mechanism enhances operational efficiency, while the square Kelly bar, made from high-strength steel, ensures durability and performance. Designed with a heavy-duty 800 mm undercarriage and a 28 mm wire rope, it’s built for demanding job sites. The dual-acting cylinder adds power to every cycle, and the grab body offers versatile interchangeability. Proudly Made in India, the DW 235 ensures easy on-site setup, reliable service, and unmatched support across metro, infrastructure, and foundation projects.
