Who We Are

Sales · Service · Overhaul — for the world's toughest fleets.

We specialise in the sales, service and maintenance of the entire range of transmissions and industrial engines — Allison, BEML, Komatsu, Caterpillar, ZF and Cummins — backed by a strong service team, workshop and inventory of parts.

For three decades we have supported mining, construction, oil-field, railways and aviation industries with reliable spares and complete solutions for dumpers, dozers, mud pumps, oil rigs, cementing units, loaders, locomotives, UTVs, wagon towers, aircraft towing tractors, air-crash fire tenders and generators.

Every part we supply is procured through genuine channels — import or authorised dealers — with complete purchase documentation as per our strict company policy.
