Introduction
The winch is special equipments designed for the requirements of borehole measurement in the field. They can be used to lift or lower down well measurement probe tube; they have the functions of automatic/manual, constant speed control, fixed points/continuous measurement, automatic depth modification, and alarm for suddenly depth change. They are in accord with the requirements stipulated in the Industry Standard of People’s Republic of China DZ/T 0196.8-1997 “Well Measurement Winch and Controller”. They are suitable for borehole measurement in geology, metallurgy, coal mining field, oil field, and engineering project, especially for well measurement in deep borehole.
