O.R. Rijken Top drive systems
Literature survey, Report 87.3.OS.2316, Transport Engineering and Logistics.

Several ways of letting the bit rotate do exist. This text emphasises the difference between drilling with the use of a rotary table and the use of a top drive (power swivel).

The idea of a top drive is not new, but lack of sufficient power made the use of it impossible. Today's top drive systems can compete on an economical basis with a rotary table, contrary to ideas that exist with some people.
