The THH9 is the latest driven pile rig created by MAIT to drive pre-cast square concrete piles, cased piles, H-beams piles, etc.. This machine offers unmatched stability for driving piles in the most difficult working conditions.
The THH9 has been specifically designed to mount MAIT hydraulic hammers (from 3 to 9 tons) as well as from other manufacturers upon request.
Another special feature of the THH9, is that the mast is equipped with a telescopic boom that simplifies the centering of the pile by extending the mast horizontally outwards to 1.000 mm (3.3 ft). Piles can be driven vertically as well as inclined, depending upon pile and hammer characteristics.
Thanks to the ability of THH9 crawler cylinder’s stroke, the expandable crawler undercarriage offers enormous advantages for transport and stability during the work phase because of the great range of its dimensions from 3.000 to 4.500 mm (10 - 15 ft).
