The machine was recently involved in drilling two 13 metre deep well installations for heat recovery not far from the company headquarters for a neighbouring industrial firm. The small size of the machine combined with its extremely robust properties made it the perfect choice for the job. The two winches with a tensile force of 60KN each ensure that the 162 hp arrive where they are needed. "Several bore holes often have to be drilled one after the other. With its high manoeuvrability and compact dimensions, the SENNEBOGEN 620 HD is particularly quick and easy to use and load", another advantage highlighted by colleagues Tim Fritzsche and Martin Zebrowski. The folding boom proved especially beneficial. BauGrund Süd uses the machine, which was supplied in February 2012 by IBS GmbH, exclusively for well drilling work. Drill pipes from DN 622 to DN 1080 are used to drill into the ground. BauGrund Süd places great importance on environmental aspects and the bio-hydraulic oil used in the machines makes a value contribution in this area. Air conditioning, comfortable seats and a pleasant working environment are important factors for the operator in particular. The 620 HD with state-of-the-art technology has replaced its now retired predecessor - a 20 year old SENNEBOGEN S 1020 R, which provided a reliable service for its entire working life, most recently at BauGrund Süd.
"We are completely happy with the SENNEBOGEN 620 HD. It is agile and easy to transport, which is a key time factor. It is also comfortable, user-friendly and offers the highest possible environmentally friendly operation and quality", states a satisfied Rainer Hierlemann, head of machine technology at BauGrund Süd.
