ABSTRACT
Performance characteristic of modern drive of 400 kW power equipped with hydrodynamic coupling and planetary gearbox has been described in this paper. This coupling is hydrodynamic one with controlled water flow of the 562 DTPPWL type produced by Voith-Turbo Company. Planetary gearbox is of the new construction with four satellite wheels. Head and tail drives of this type secure soft start-up of AFC of the Longwall-800 type. In order to evaluate cooperation correctness of both drives and a soft start-up process this AFC has been subjected to an examination on the face number 522 at the Piast coal mine. Measurement method applied in real objects in exploitation conditions has been presented. Results of research and conclusions have been also contained in this article.
