The GTB 1500 neo with hydraulically operated wireline percussion system for pulse operations is mounted on a rigid steel frame and is amply powered by a Hatz Diesel engine. Bailing in conjunction with casing tubes and push/pull clamps is the main objective. Depths around 100 m are reached depending on rope length. Four hydraulic legs swiveling inward as well as folding mast head and foot parts make for small transport dimensions.
