Construction
The Smart Winch is a 12 Volt high torque winch mechanically designed
for the depth requirements of drill sites, with the capacity to hold up
to 2,000m of 1/8”, or 913m of 3/16” cable. It is light enough to be
portable, but it also has bolt-down points which allow it to be securely
fastened to a vehicle. It is a versatile but powerful winch that maintains
a small, compact footprint of just 675mm x 740mm x 430mm. The
powder-coated finish on the aluminium side plates protectsthe winch
from the elements.
Cable Spooling
The Smart Winch 12V is designed to be accurate. Its cable laying system
uses a mechanically-designed helicon shaft that is CNC machined to
ensure each layer of cable is precisely laid on the drum.
Slip Rings
Only the best Slip Rings are used on the Smart Winch. They provide
reliable, uninterrupted communication between downhole instruments
and surface acquisition systems. A two-way mercury Mercotac slip ring is
used for single conductor cable, while a 6-way Techtron slip ring is used
with 4-conductor cable.
Motor and Controller
With a lifting capacity of 150 Kg, the Smart Winch is powered by an
extremely reliable 0.7Kw 12 Volt motor and driven through a 40:1 worm
drive gearbox that is small enough to fit inside the winch housing. Its short
circuit, transient and overload protection is enclosed in a rugged IP65
control enclosure. A variable speed controller and additional sensitivity circuitry ensure smooth speed control from 1 metre per minute to a
maximum drum speed of 35 metres per minute.
Depth and Rate Measuring
Depth and Rate (m/min) are measured by an optical depth encoder
and displayed on a programmable LCD monitor. The system is factory
calibrated, providing accurate depth and rate measurements. The
measuring wheel is machine-grooved and provides continuous cable
contact using a spring-loaded pressure wheel combination that tracks
along the helicon shaft.
Brake
An operator-controlled Multi-disk brake provides a positive park or
stationary position. Additionally, each winch is fitted with an emergency
STOP button.
Warranty
Every winch is covered by a 5-year warranty on the frame and one year
on all other components.
