Pulley Assembly
The
pulley assembly is clamped to the top of the inclinometer casing.
It speeds operations, helps the operator maintain consistent
depth control, and protects the cable from abrasion on the edges
of the casing.
Consistent positioning of the probe
is essential for good results with the inclinometer. The pulley
assembly assists two ways: first, it allows the probe to be drawn
up smoothly, with no backtracking, and second, its cable clamp
provides a convenient reference for the depth marks on the cable.
The cable clamp also provides the operator a brief respite from
the weight of the cable and the probe.
The pulley is made from aluminum and has a brass axle. The clamps are made from carbon-fiber which does not freeze up in cold weather.
The pulley assembly is available in two sizes. The small size
fits 48 and 70 mm (1.9 and 2.75") casing, and the
large size fits 70 and
85 mm (2.75 and 3.34" ) casing.
