Selecting the right Winch
Auslog manufacture a wide range of world renowned winches, from small hand-portable 450 m through to 3000 m capacity models. Our winches are widely recognised for their exceptionally high quality construction, corrosion resistant materials, advanced design and reliability under the most extreme conditions. No other winch on the market today has such a proven record for reliability, lifetime and value. The winch system is often given less consideration than the data acquisition system or the logging tools. With this in mind Auslog provides a large range of rugged, reliable and trouble free winch systems.
Auslog have a winch to suit every application
Auslog manufacture a range of winches suitable for all types of geophysical logging cable. All our Winches come standard with single-ended quadrature signal optical depth encoders. Our four conductor Winches can also be fitted with Differential, quadrature signal optical depth encoders but only if requested by the customer.

Technical Notes
Nonmagnetic Construction:
Winching systems are of a strong nonmagnetic construction, using mainly aluminium and stainless steel. This is done to reduce interference particularly in electric logging tools. A secondary benefit is a significant reduction in weight.
Motor Drive Power:
Optional motor drive power of 12VDC, suitable for all single conductor models. 110 VAC and 240 VAC is also available. A remote contol is supplied with all models. It is recommended that power be selected that conforms to local area power requirements. This is particularly useful for connection directly to mains power during times of training, testing and repairing.
Logging Speed:
The speed control for the winching system is variable between 0 and 30 metres per minute (0 and 100 feet) with accurate logging speeds between 0.5 and 30 metres per minute (2 and 100 feet). If special speeds less than 0.5 or more than 30 metres per minute are required consult the factory so appropriate gear ratios can be fitted.
Brake System:
This winching system is provided with a disc brake system for maximum operator control and safety. The manual disc brake is a locking brake for holding the winch stationary or can be used for emergency stopping or for control when lowering tools into the borehole, a second hydroloc activated brake is fitted to most of the largher models.
Speed Control:
The winching system when used with a motor drive includes solid state variable speed controller with remote control. This can be mounted near the winch in a self contained box or can be remotely installed in a cabinet with the other logging instruments. For cabinet mounting the controller unit is Euro construction and a Euro bin is required.
Depth Counter:
The mechanical counter is mounted on all winch's in a convenient location. It provides a reading in metres and tenths of a metre. For depth measurement in feet the reading is in feet and tenths of a foot. The counter is spring loaded and can be easily reset to 0 or other predetermined depth.
Measuring Wheel:
The precision measuring wheel is made from stainless steel and allows for accurate measurement of tool depth. Depth measurement accuracy better than 0.01% is standard.
Depth Encoder:
A unique electronic depth sensor mounted in the measuring wheel assembly provides an accurate pulse signal used for driving chart recorders, digital readout display, or for storage of log tool data on magnetic tape or disk. The interval between depth pulses is 10 mm which allow for very accurate recording of depth and log date.
Cable Spooling:
An automatic cable level wind system is incorporated with the measuring wheel assembly. The measuring wheel tracks across the cable drum to provide a neat consistent cable lay. A manual adjustment capability is included.
