Soilmec SR-80 C : New drilling rig for LDP and CFA

Soilmec SR-80 C

After the great success earned by the SR-70, SR-90 and SR-100 introduced since 2005, Soilmec offers to the demanding foundation market the possibility to choose a new rig jointing in the same machine the experience dued to SR Soilmec series to that one of Caterpillar. In fact SR-80 C is a perfect mix of CAT base machine turret (345 C) with Soilmec standard rotary. CAT C13 engine generates the considerable rated power of 328 kW at 1800 rpm with that important guarantee of reliability, quality and durability that have made CAT famous around the world.

Noteworthy are the performances of SR-80 C. It’s possible to drill large bored piles with a maximum diameter of 2,000 mm, at a depth of about 80 m, while in case of CFA (continuous flight auger) the rig has been conceived for piles up to 1,200 mm at a depth of 25 m.

The multifunctionality of SR-80 C is testified by the possibility to be fitted with crowd system made by whether winch (13,000 mm stroke – standard) or cylinder (6,500 mm stroke – optional). In alternative to the standard spin off rotary, the customer can select the innovative shifting gear rotary, with a mechanical 3 high speed gear. This new solution allows to have a nominal torque range that varies from 292-132 kNm, that permits an higher production in terms of m/h and better rotation-to-torque ratio, with a max drilling speed that varies from 27 to 107 rpm.

As for the other Soilmec machines based on a CAT turret, the winches are positioned in the lower part of the mast, in front of the cabin, to permit to the operator a constant check. The main winch has a maximum pull of 260 kN and a speed of 75 m/min, while the auxiliary winch has a maximum pull of 100 kN and a speed of approximately 65 m/min. The machine can also be arranged with a free fall service winch with 80 kN nominal line pull.
