2021 SOILMEC ST-20

Umbrella Drilling Rig, ideal for sub-horizontal consolidation in tunnels with a work radius of between 1512 mm and 4696 mm (with the drilling mast horizontal at 0°). The useful stroke of the rotary allows treatments of up to 14 m (16 with the optional extension). The drilling mast can be folded in at both ends, reducing the overall dimensions, to make the rig easier to transport both underground and on the road at the end of the job. The machine has two motors (diesel and electric) of a suitable size for each single motor to perform all the drilling, traversing and positioning operations of the crawler. The following drilling techniques can be applied using the ST-20: - Rotation (with or without casing) - Rotopercussion by means of Top Hammer (with or without casing) - Rotopercussion by means of Down the Hole Hammer (with Tubex, Odex or Simmetrix superjews system) Technical data Diesel enginekW123 + (90) Weightt21 Working radius at 0°mm1700 ÷ 4696 H max from ground level at 0°mm6196 Max TorquedaNm1350 Max hoistkN67 Feed strokemm14200 Clamping rangemm60-260 Track shoe widthmm400, "CE" Certified, One owner since new
