Geophysical Logging Winch Automatic 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.

II. Instrument characteristics 1. They have functions of automatic/manual, constant speed controlling, fixed point measurement/continuous measurement, and depth modification (depth correction). 2. It is highly automatic; the constant speed controlling performance can meet the requirements of grade A of the standard DZ/T 0196.8-1997; 3. It can automatically stop when the power is cut off and it also can automatically stop when the speed is abnormal or suddenly changes for operation safety. 4. LCD display, humanization operation, and comprehensive information in real time;
