DESCRIPTION AND APPLICATION
Telescopic kelly bars produced by S.A.I.C.I. are made up of high tensile steels. The prismatic profiles connection are in extruded steel and they are welded with automatic system. The proposed range is suitable for machines having a torque from 10.000 daNmt to 24.000 daNmt with telescopic elements in groups of 2, 3, 4, 5 up to 12 meters in lenght. Thrust and connection system can be friction or mechanical interlocking.
