TREJON AB - 13 - www.trejon.se
1. SAFETY REQUIREMENTS
1.1. Winch is designed and constructed for one person operating. Operator has to be
skilled and familiar with present manual.
1.2. Every day before starting work with winch, inspect that machine is in working order.
Remove defects if necessary. Particularly turn attention to the condition of the cable
and hooking chains. If replacing hooking chains or wire, you will have to remember
that their pulling force on braking is twice bigger then pulling force of the winch.
1.3. For any kind of adjustment or maintenance stop the tractor and be sure it’s enable to
start without an operator.
1.4. It is strongly forbidden to remove safety protectors from the winch.
1.5. Winch has to be operated not closer then 5m from working machine.
1.6. Look at the position of the winch: it has to be stable and cable must run in the direction
of the long ways of tractor. Avoid the tractor of falling over when pulling the logs to side
direction.
1.7. Keep people, especially children away from the working machine as far as possible.
Working zone in about 100m in radius has to be limited and supplied by indicating
signs.
1.8. It is not allowed to touch spooling cable or when cable being under the tension.
1.9. It is strongly forbidden to direct moving logs manually or ride on the moving logs.
1.10. Look at reliability of hooking. Logs must be fastened properly.
1.11. It is not allowed to use cable as hooking wire/chain.
1.12. Operator has to use personal safety protectors.
1.13. It is forbidden to use winch for transporting people/goods or to use it as a blade.
2. PRINCIPLE OF FUNCTION AND OPERATION
This winch has a cable drum driven by the tractor’s running power by means of a cardan shaft
and chain transmission equipped with a mechanical friction clutch.
Winch is operated by means of three main elements: two strings, (pos. 1 and pos. 2) and lever
pos.3 (see drawing 1).
white string pos.1 – switching friction clutch
dark string pos. 2 – switching band brake
lever 3 – switching band brake
Mechanism has three positions: initial, preparatory and working position.
I - Initial position
(see drawing 4)
Clutch open
Brake closed
Drum is fixed and
doesn’t turn
II – Preparatory position
(see drawing 5)
Clutch open
Brake open
Drum is not fixed,
doesn’t turn, cable is in
state to be pulled
III – Working position
(see drawing 6)
Clutch closed
Brake open
Drum is turning. Cable is
spooling on the drum
Pulling dark string 2, band brake is being released. Pulling white string 1, drum 6 being on
axes 5, through sleeve 7, will be clutched to chain wheel 8. Chain wheel is driven by tractor
PTO through chain transmission 9. Drum starts turning and spooling the cable 10 on the drum.
To haul the logs out it is necessary to pull both strings at the same time. When strings are
flabby, springs 22 and 23 will bring clutch and brake back into initial position: drum will stop
and fix. Pulling cable off the drum, it is necessary to release the band brake, either pulling
string 2 or pushing lever 3, and due to that locking teeth 11 and 12 of levers of clutch will lock
to each other (see drawing 5).
