They are 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.
