Description
Purpose:
It is a portable special device used to rise up and lower down
borehole determination instruments and cables in physical
exploration, hydrology, and coal field. It is small, light and
convenient to be operated.
If use WTOEF seven cores cable (Ø*1.3 mm), it can be used
for determining borehole, which is up to **0 m in depth; if use
YHK*4 sheathed four cores cable (Ø4.*6 mm), it can be used for
determining borehole, which is up to ***0 m in depth. It uses
mechanical chains as driving device, so it is compact. It adopts
frequency regulator to control speed of motor, so its peed can be
continuously adjusted.
Slip ring adopts four cores output, and it can determine and
transmit test data of borehole. The winch is mainly composed of
frame, roller, motor, reducer, and controlling case.
