INSTRUCTIONS FOR USE
1. Description
The winch is a machine intended for storing chopped logs from the forest. Basic parts of
the winch are: welded housing, drive part, drum with shaft, clutch, brake, upper and
lower pulley and other smaller elements. Control is done by electro hydraulic system.
Clutch and brake are engaged by hydraulic cylinders. Pressure in the hydraulic part is
created by the hydraulic pump, which is driven by the PTO shaft. Hydraulic battery
maintains required pressure in the system even after the pump becomes still or the tractor
is shut down, which still enables to unwind the wire rope. Steering elements are powered
by electricity from the electrical socket at the rear of the tractor. The winch operates with
hydraulic pressure to maximum 160 bar.
Safety valve is factory set and the pressure is not allowed to be increased!
2. Required equipment of the tractor
- PTO shaft with chosen gear ratio, max. 540 RPM.
- Three-point hitch of I and II category.
- Electrical installation 12 V with socket on the rear of
the
tractor.
Maximum number of revolutions and direction of tractor PTO shaft rotation is 540 min
-1
.
3. Pto shaft adjustment
Length of PTO shaft needs to be adjusted for different tractors (figure F1
-F4). For winch
45H/55H/55Hpro, the use of PTO shaft with torque 695 Nm (type W 400E Walterscheid) is
appropriate.
Ascertain the accurate length in the following manner:
1.
Shut down the tractor.
2.
Connect the machine to the tractor.
3.
Extract the PTO shaft apart and connect the individual shaft halves to the tractor
and machine and compare them crosswise and mark them (figure F1).
4.
Shorten external and internal plastic protec
tion pipes (figure F2).
5.
Shorten external and internal slide profiles with the same distance as plastic
protection pipes (figure F3).
6.
Crop the pipe end, remove fillings and grease the slide positions well (figure F4).
