Hydraulic Winch / Rope Reever / Cable Drum Rotator
Please Scroll down or click on choice above.
147 Series winches are
direct drive hydrostatic braked winches which may have
fail-safe brakes fitted if required. They are suitable for
use in small drilling rigs, for drill rods and other
winching applications. Drum size is 100mm and the weight
noted below for the winch is approximate only and does not
include the weight of any wire. Other drum sizes are
available as well as two speed winches.
Some power cable tensioning
bull wheels do not provide a means to control the layers of
takeup rope during pre-tensioning of the transmission power
wires. We have made these rope reeving machines so that the
operator can move the fairlead rollers across to ensure
better layering of the rope. It is also safer not to have an
operator manually using a hook device to pull the rope to
help the layering which is what we have seen happen in the
field. We can install and set up the operator console so
that the sense of direction on the hydraulic valve handle is
the same as the direction the reever is required to move. It
also means that the reeving control is from the safety of
the enclosed operator control console.

Our cable drum rotator is
compact and amazingly powerful. Although the rotator fits
underneath the cable drums from 1 to 1.8 metre diameter, the
wear resisting lagged urethane roller self adjusts for the
load generated by the cable. A unique and simple system
places the raise and lowering cylinder in the same hydraulic
circuit as the drive roller. This results in increasing
gripping forces as the load increases on the roller. We have for many years specialised in the manufacture of light weight and high powered products. Although we have seen others produce cable drum rotators of the same capacity, they have used 14 hp engines and yet still only achieve the same speed and power as ours. This is an "over kill". The engine is far too large for the job. We use a 5hp Honda or Briggs & Stratton engine in a small sized roll bar (460 mm x 460 mm x 465 mm, weight 35 kg).
