IMT was founded in 1974 by Mr. Giulio Accorroni, inventor of the first drill rig back in 1958, when water wells were still made using non-industrial methods. This drilling rig was the first rig ever built in Italy, using the driving force of a tractor.

He immediately established the two key factors that, also today, remain the cornerstone for all manufacturing companies in the drilling sector.

The innovation of a completely hydraulic and non-mechanical rig. Mr. Accorroni immediately recognized the importance and the considerable difference of the hydraulic system, especially when applied to the field of earth-moving machinery.

With absolute genius, Mr. Accorroni also came up with the idea of the first telescopic kelly bar with interlocking system, and even today, 45 years since his invention in 1973, companies all over the world are still using this brilliant system. This rods locking system during the rotation phase, allows our drills to guarantee that the weight of the entire machine is transferred and applied to the drilling tool during the pushing phase.

In 1980, IMT started to export its drill rigs abroad. From then to now, our reference markets have been mainly North America, (where we have sold over 800 units and are the leader in the field of foundation piles for over 20 years), South East Asia (with about 500 units sold) and over 700 units more sold between the Middle East, Europe and the rest of the world.

In 1993 IMT started collaborating with Caterpillar and, in a few short years, became its main client for special applications mounted on CAT bases.

IMT has mounted over 1,200 rigs mounted on CAT bases, starting from its smallest machines, the AF6, mounted on CAT 211B which reached a depth of 32 m and diameter of 1.2 m, up to its biggest machine, the AF460 drill mounted on CAT 385C which reaches a depth of 110 m and a diameter of 4 m.
