IMT is founded by Giulio Accorroni.


The first innovative hydraulic drill rig (model 75 type G) is patented. Capable of drilling up to a depth of 30 meters (best market performance at the time)


The Accorroni family buys 100% of IMT shares and Giulio Accorroni is appointed IMT’s sole Director.


Fabio Accorroni (Giulio’s first son) dies in an accident and Andrea Accorroni, his younger brother and current IMT President, takes over IMT management.


The company introduces the 805 model, which soon becomes very successful and used for big construction projects, such as the Sagrada Familia in Barcelona, Spain.


New innovative models are launched (i.e., sound-proof machine and model AF12, assembled on a crawler base completely produced by IMT).


Beginning of co-operation with Caterpillar (CAT): IMT starts assembling drill rigs on CAT bases (IMT is the first drill rig manufacturer to do this; other manufacturers will soon follow the example); IMT starts a distribution agreement in North America and Canada for its drill rigs mounted on CAT bases through the CAT dealer in Miami, Kelly Tractor Company In the same period, the technology for driven piles used in the U.S. until then starts moving towards the European piling system and the drilling equipment demand in the US market for all European manufacturers starts growing. 


IMT produces the AF50, the biggest drill rig in the world at the time, and sells no. 7 units to the Japanese multi-national company Sumitomo. Giulio and Andrea Accorroni are invited in Osaka for a lecture on the technical characteristics of the rig. The lecture is attended by the owners/directors of the biggest Japanese construction companies. 


IMT patents an innovative drilling system related to highly seismic grounds, the “Multi Rotary driven Soil Mixing Pile”.


IMT increases its production range and doubles its sales.

IMT reacts to the global economic crisis by launching 2 new product lines in the market with traditional technology (the “AG” series, assembled on HITACHI base, and the “A” series, mounted on IMT base), and completes the first prototype of drill rig for seismic grounds, the AF460 model, which uses the patented “Multi Rotary driven Soil Mixing Pile” system. The prototype is presented at BAUMA 2010, the most important international exhibition for construction machinery. The complete production range is developed thereafter.


IMT AGM appoints a new Board of Directors.


IMT develops the prototypes for the full range of the AF series drilling rigs with Tier 4 eninges, as well as the newly-born A125 and A150 models, mounted on IMT base and powered by CAT.


IMT upgrades the A-series machines with new engines and design, and develops its own particular water well technology system.


The new AF-series machines, mounted on CAT bases with Tier 4 Final eninges are developed and lauched into the market, as well as a brand new range of A-series rigs with Tier 3 engines, completely designed and developed by IMT.


The brand new range of A-series rigs with new engines of last generation, completely designed and developed by IMT, is launched into the market.


With its AF280 model, IMT has significantly contributed to the reconstruction of Ground Zero in New York City, NY, U.S.A.


IMT has carried out all piling jobs at the
Sagrada Familia in Barcelona, Spain
