From a modest workshop in 1972 to a global drilling powerhouse—the story of a man who built machines on principles.
The journey of PRD Rigs began in 1972 with the determination of Mr. T. P. Thangaraj, a technocrat-entrepreneur who believed that excellence in engineering could transform industries. Starting with a modest workshop, Paranthaman Engineering Works, he focused on delivering high-quality mechanical services at a time when structured service standards were rare. His early specialization in axle servicing for Ashok Leyland trucks reflected both technical competence and business courage—particularly when he introduced a two-year warranty, a bold promise in that era.
This commitment to quality and accountability quickly earned him respect across Tamil Nadu. For Mr. Thangaraj, customer confidence was not a marketing strategy but a principle. His foundation was built on disciplined workmanship, transparent dealings, and an uncompromising focus on reliability.
A Turning Point that Defined an Engineering Philosophy
The early 1980s marked a pivotal phase in his entrepreneurial journey. While observing a UNICEF-backed Government of India drilling initiative, Mr. Thangaraj studied the functioning of an imported hydraulic rig operating in Tiruchirappalli. Despite its high-depth capacity, the machine was being used efficiently for relatively shallow drilling tasks.
This practical exposure reshaped his thinking. He recognized that real-world performance mattered more than theoretical maximum capability. From this insight emerged a long-standing engineering philosophy—design machines that are robust, adaptable, and aligned with field realities rather than simply impressive on paper.
Inspired by this approach, he transitioned from repair services to manufacturing. Paranthaman Rock Drills (PRD) introduced its first water-well rig, signaling the company’s entry into the drilling equipment space. By 1982, pneumatic rigs were added to the portfolio, setting the stage for structured growth in the sector.
Expanding Horizons Across Markets
The decade that followed witnessed steady expansion. PRD Rigs began supplying equipment beyond Tamil Nadu, extending its footprint into neighboring states. With more than 900 rigs delivered during the decade, the brand steadily built a reputation for durability and dependable after-sales support.
Under Mr. Thangaraj’s guidance, the company diversified into water well, mining, infrastructure, and exploration segments. Continuous investments in manufacturing systems, process optimization, and quality certifications strengthened operational excellence.
A Legacy that Powers Global Growth
Today, PRD Rigs reflects over five decades of sustained engineering progress, with more than 4,000 rigs delivered across 75+ countries worldwide. The company has earned multiple EEPC India Export Excellence Awards and operates with IMS-certified facilities, reinforcing its global credibility.
Beyond commercial success, Mr. Thangaraj’s leadership played a role in positioning Tiruchengode as a thriving rig manufacturing cluster, widely referred to as the “Drilling Rig Capital of India.”
His legacy continues through Mr. T. T. Paranthaman, Managing Director, who is steering PRD Rigs toward greater global expansion and technological advancement—anchored firmly in the founder’s enduring values of integrity, service, and long-term commitment.
