PRODUCT DESCRIPTION
A winch is a machine intended for harvesting felled timber from the forest. The basic components are welded frame,
driveline, drum with wire rope, directional pulleys, friction clutch and a brake.
In FARMI winches, there are two different kinds of brakes: models W30F, W35R and W50R are operated with
ratchet brake and models W35F, W50B, W60B and W86B with automatically switched on band brake.
There are also two different type of control systems in FARMI winches: 1) Manual control where two ropes are used
by operator to control the unit or 2) electro hydraulic control where operator uses remote control instead of ropes.
In this case, functions are operated with hydraulic cylinders.
Using the wire rope, the logs can be towed to the winch and anchored with chains to the winches slotted dozer plate.
After this logs can be transported to a place where other means of transport are accessible. FARMI winches may
not be used for lifting! Factory setting values may not be changed without a permission of Farmi Forest.
