CHDJ Series Winch

Description
CHDJ series winch is a special equipment for geophysical exploration andgeological survey. It is mainly used with CHJHQ-2D integrated digitallogging equipment and can also be used with other logging equipment.Most CHDJ series winches are anti-magnetic design, stepless speedadjustment and automatic cable arrangement. The performance can beapplied to various geological prospecting areas. CHDJ series winchequipment adopts frequency conversion motor, dc motor, acasynchronous motor as power source, and has a wide range of speedregulation, smooth variable speed, convenient operation, simplemaintenance and so on. It can be used in geophysical prospecting andgeological survey work on the land, sea, plateau (which is less than 5,500meters above sea level) and other environments on the earth.

Features & Benefits
1 Power
CHDJ series logging cable winch is powered by marine frequencyconversion motor, tombarthite permanent magnet DC motor, industrialfrequency conversion motor, dc motor, ac asynchronous motor as powersource. The selection of power source mainly considers the factors suchas high temperature and humidity environment, high altitudeenvironment, convenient field transportation, convenient maintenance,long-term continuous operation and so on, so as to ensure the reliabilityof the whole set of equipment.

2 Automatic cable arrangement function
Most CHDJ series logging cable winch has automatic cable arrangementfunction, which ensures that the cable can be precisely and neatlyarranged when dropping and lifting, and can greatly prolong the servicelife of the measuring cable. It is very important that the winch hasautomatic cable arrangement function especially for steel wire armoredcable.

3 Automatic braking function
CHDJ series logging cable winch has the automatic braking function. Thewinch can automatically stop when encountered in the use process ofemergencies, such as power outages, winch controller failure and so on tokeep the tube safe, so the tube will not fall.

4, Manual function

The CHDJ series logging cable winch is equipped with a handle, which candrop or lift by hand without electricity in special circumstances.

5. Accurate measurement of cable length

The CHDJ series logging cable winch has precise cable metering device toensure that the instrument has an accurate depth in the process of liftingor dropping of cables.

6, Resistance to salt fog
Main components of CHDJ series cable winch for Marine geophysicalsurvey adopt high strength aluminum alloy as the material. The surface iscoated with electrostatic spraying, some fasteners are stainless steel. Ittakes Marine ac motor as power source, and the cable has kevlar wire andwire twisted rope core and it is coated with polyurethane.

7, The magnetization
For the purpose of electric logging, magnetic logging and otherprojects, the main structure of the CHDJ series logging cable winch adopthigh strength aluminum alloy as material, which ensures that the loggingcable can not be magnetized, and keep the minimum amount of self andmutual inductance.
