S
afety for operators and ground personnel is of prime
concern. Always take the necessary precautions to
ensure safety to others as well as yourself. To ensure
safety, the tractor and winch must be operated with
care, concern by the operator for the equipment and a
thorough knowledge of the machine's performance
capabilities. The following recommendations are offered
as a general safety guide. Local rules and regulations
will also apply.
1. Read all warning tag information and become
familiar with all controls BEFORE operating winch.
2. Never attempt to clean, oil or perform any mainte-
nance on a machine with the engine running,
unless instructed to do so in the Service Manual.
3. Before starting tractor, be certain all controls move
freely and are placed in the "Brake-On" (neutral)
position.
4. Never operate winch controls unless you are prop-
erly seated at the operators station on the tractor
and you are sure personnel are clear of work area.
5. Operate winch line speeds to match job conditions.
6. Assure that personnel who are responsible for
hand signals are clearly visible and that the signals
to be used are thoroughly understood by everyone.
7. Never attempt to handle winch cable when the
hook end is not free.
8. Leather gloves should be used when handling
winch cable.
9. Ground personnel should stay in view of tractor
operator and clear of winch drum. Do not allow
ground personnel near winch line under tension. A
safe distance of at least 1½ times the length of the
cable in use should be maintained.
10. When winding cable on the winch drum, never
attempt to maintain tension by allowing cable to
slip through hands. Always use "hand-over-hand"
method.
11. Use correct size ferrule for cable and pocket in
winch drum. Never use knots to secure or attach
cable.
12. Inspect rigging, winch and tractor at the beginning
of each work shift. Any cable with broken strands
of rigging worn or damaged should be replaced.
13. Position tractor for straightest line of pull. Use fair-
lead if side pulls are frequently encountered.
14. The cable anchor or ferrule pocket in the cable
drum is designed to provide a self release in the
event a back-sliding load must be released from
the tractor in an emergency situation. The cable
anchor or ferrule alone will
NOT support rated
linepull. Therefore, a minimum of five (5) complete
wraps of cable must be maintained on winch drum.
15. Be sure of tractor ground stability before winching
in load.
16. Store unused chokers, slings and rigging in a neat
and orderly fashion to prevent damage to equip-
ment or injury to personnel.
17. The maximum rated bare drum line pull of the
CARCO 50B is 69,200 LB (307.8 kN)* and 89,800
lb (399.4 kN)** for the CARCO 70A. Do not oper-
ate the winch under loads that exceed the maxi-
mum rated bare drum line pull. If excessive loads
are encountered, use a multi-part line and sheave
blocks. Any attempt to exceed the capabilities of
one winch (such as coupling 2 or more tractors
together) is extremely hazardous.
*
Breaking strength of 7/8 in. (22 mm) IPS wire rope.
**Breaking strength of 1 in. (25 mm) IPS wire rope.
18. The factory approved adaptions for CARCO winch-
es are designed and intended for use on specific
models of crawler tractors. Changing winches
between tractors is not possible in some cases
because of differences in tractor models. Some
changes cannot be approved by CARCO because
of safety limitations. Call a CARCO dealer or the
Factory prior to attempting winch modifications or
before mounting on a different tractor.
19. CARCO power shift winches are equipped with
hydraulic accumulators. Discharge accumulator
stored oil supply before removing any hydraulic
lines or fittings or servicing winch. Personal injury
may result from the sudden release of oil pressure.
To discharge the accumulator, stop the engine,
slowly cycle the Power Shift control handle into full
Haul-In then Pay-Out positions a minimum of five
(5) times.
20. On machines having hydraulically, mechanically
and/or cable controlled equipment, be certain the
equipment is either lowered to the ground or
blocked securely before servicing, adjusting and/or
repairing the winch. Always apply tractor parking
brakes and lower equipment before dismounting
the tractor.
