PRE-OPERATION CHECKS
MOUNTING AND USE OF THE LOWER
SNATCHBLOCK
• Usually the logs are winched in through the up-
per diverting pulley of the winch. This lifts the logs
and they dig less into the ground. The weight of
the load also pushes the blade into the ground
thus anchoring the winch and the tractor to the
ground.
• The winch has a lower diverting pulley. The main
use of the lower diverting pulley is to lower the
pulling point. This enables larger loads to be skid-
ded out . For skidding out the load the cable is
transferred to the lower diverting pulley.
• Several logs can be hooked up and winched in at
one time by means of keyhole sliders on the cable.
The skidding chain should have a pin on the end,
which makes it easier to pass the chain under-
neath the tree. See fig. 8.
When using the lower diverting
pulley make sure that it follows
the direction of the cable. Other-
wise the cable will be damaged,
when it is pressed between the
snatch block and the lower diver-
ting pulley frame.
When winching an unloaded
cable, make sure that the finger
guard doesn’t rise up with cable
and doesn’t cause cable to cross-
cut.
