terms these choices Level 1, for ripper
hydraulics; and Level 2, for dedicated
winch hydraulic system.
For maximum performance, the dedicated pump is the preferred choice. A
hydraulic winch with dedicated pump
is what we call the Hi-P (High-Performance) winch. A winch driven by
ripper circuit is what we call a Rescue
winch. Both develop similar line pull,
but line speed will be different.
The Hi-P winch delivers fast line speed
for high-production work such as logging. The rescue winch, a lower-price
option, typically has slower line speed.
The big advantage for rescue winch is
the total ease of installation.
The Allied H4A rescue winch can be installed on a non winch-ready D31-D37-D39-22 dozer from
dealer stock. Allied winches come with all necessary mounting brackets and controls.
E
verybody seems to prefer more
choices. Even in the world of dozer
winches, choice is an advantage. For
several new models in the Komatsu
line-up, dealers and customers now
have an unparalleled range of options
for equipping the dozer with a winch.
The new models, D31-22, D37-22,
D39-22, and D51-22, are all hydrostatic tractors. None are equipped
with PTO to power a traditional PTO
winch. Hydraulic winch fills the bill
in this case. The secret to flexibility is
the range of options that a hydraulic
design affords.
The key variable is the source of
hydraulic power to the winch—an
auxiliary circuit, typically the ripper circuit, or a dedicated pump engineered
specifically for the winch. Komatsu

The other main choice is whether the
winch hydraulics are factory installed
or field installed. The option to install
the hydraulics in the field allows a
stock tractor to be outfitted with a
winch more quickly than waiting for a
factory equipped dozer to be delivered.

The Komatsu D31-22, D37-22 and
D39-22 take the Allied H4A winch,
with a line pull rating of 40,000 lbs.
The Komatsu D51-22 takes the Allied
H5C winch, rated at 50,000 lbs line
pull.
The Allied H4A and H5C winches
share similar characteristics. Both have
a variable speed motor to permit high
line pull when heavily loaded and fast
line speed when lightly loaded. The
winch motor turns only on demand,
which reduces noise and wear. Winch
control is through a single lever,
which requires only fingertip pressure
to operate.
Standard features on both models
include power in, power out, and
freespool. Options include 4-roller
fairlead and integral log arch. On H4A
Hi-P winch, a slow-speed gear ratio is
available when greater peak line pull
is required.
cable through underground conduits, and other work that requires
precise control of heavy loads. The
beauty of the Allied winch is that it is
engineered for the rigors of a dozer
winch.
The winch can be ordered with
everything required for field installation. For Rescue winch, installation
time could be as short as 4 hours on
ripper-equipped dozer. It’s just a matter of bolting the winch to the dozer
and connecting the hydraulics—what
we call a “plug ‘n play” solution.
Komatsu now has available a brochure on Allied winch that elaborates
the characteristics and features of
the various Allied winch models.

A hydraulic winch delivers exceptional control over line speed and line
position. As a result, the winch excels
in applications such as power line
sagging, pulling pipe for re-lining old
pipelines and sewer systems, pulling

The H5C rescue or Hi-P winch can be readily installed on any non winch-ready D51-22 dozer,
whether bare-back or with ripper hydraulics.
