Advanced plants delivering precision manufacturing and reliable repair for diesel engines.
Tanna Cranktech operates three advanced production facilities—two near Rajkot (50,000 sq. ft.) and one at Taloja, Navi Mumbai (15,000 sq. ft.)—dedicated to manufacturing and repairing crankshafts, piston rods, crossheads, mud pumps, fuel supply pump shafts, and other major engine components.
Tanna Cranktech operates two state-of-the-art plants near Rajkot, Gujarat, covering a total area of 50,000 sq. ft. These facilities specialize in the manufacturing and repair of crankshafts, piston rods, crossheads, mud pumps, fuel supply pump shafts, and other critical components for diesel engines and air compressors. Equipped with modern infrastructure, these plants ensure efficient workflow and precision-driven production for industrial and power sector clients.
Our Rajkot plants feature high-precision grinding equipment imported from Vereco Spa, Italy, with vibration-free operation and microbalance controls capable of handling crankshafts up to 7.5 m in length and 8,000 kg in weight. The Saint-Gobain grinding wheels (France/USA) and tropicalized setup guarantee uninterrupted performance even in extreme ambient conditions, ensuring all components meet strict OEM standards.
The Taloja plant in Navi Mumbai, spanning 15,000 sq. ft., is dedicated to serving marine industry clients with time-bound, high-accuracy component manufacturing and repair services. This facility is strategically located to support marine operations, ensuring faster turnaround and on-time delivery for critical engine and compressor components.
The grinding machines at Taloja, like those at Rajkot, maintain exceptional accuracies as per DN standards. Trueness is within 0.01 mm, while concentricity, cylindricity, circularity, and parallelism are kept within 0.02 mm. The run-out of crankshafts is maintained strictly within OEM recommended limits, ensuring every component delivers optimal performance and long-term reliability in demanding marine environments.
