Jch-1000 Automatic Geophysical Well Logging Winch

Jch-1000 automatic geophysical well logging winch
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.
