Geophysical Borehole Logging Equipmement Borehole Resistivity Logger Geophysical Well Logging Tools
DJ (vehicle-mounted) series logging cable winches are special equipment for geophysical exploration and geological survey. They are mainly used in conjunction with GDQ-2D comprehensive digital logging equipment, and can also be used in conjunction with other logging equipment. Most of the DJ series winches are designed with anti-magnetic, stepless speed regulation, and automatic cable arrangement. Its performance can be applied to various geological exploration fields. It can be used in geophysical exploration and geological survey work in plateaus (altitude <5500 meters), on land, at sea and other environments.
Function
1. Self-locking function, overload protection, stable speed without jitter.
2. Use advanced variable frequency speed regulation technology to control the winch.
3. Unique automatic cable arrangement technology.
