Abstract (en)
[origin: EP0518297A1] The present invention relates to drilling equipment with a tool which can be lowered into the ground. The drilling tool can be operated over a large speed range with considerable disintegration if the drive for the drilling tool is formed from at least two drives (28, 30) which are coupled via a superimposed or differential mechanism (32). <IMAGE>
