A snatch block is an important aid to successful winching and can be used to
increase the pulling power (or mechanical advantage) of a winch, or change the
direction of a pull.
Where a double line pull is used (i.e. where a snatch block is used at the load or
anchor point and the winch rope is connected back to the vehicle), twice the pull
force is applied but the speed of recovery is halved.
One snatch block can be used in an indirect pull where the vehicle is limited due to
unsuitable ground or obstruction. In this instance, the pull on the load is the actual line
pull of the winch.
If more than one snatch block is used, they must be located at least 1m (40″) apart
A tree trunk protector strap is useful for connecting a rope to almost any anchor point but
is primarily designed to prevent a tree from ring barking. The tree trunk protector should
be wrapped around the chosen tree or anchor point as low to the ground as possible
and the two ends brought together and joined with a bow shackle. The bow shackle
then becomes the recovery point to where the rope or extension strap is joined.
A recovery damper is a safety device designed to help eliminate the possibility of injury or
property damage in the event of a rope failure. Placed in the middle third of a live rope,
in the event of the rope breaking, the damper can help absorb the energy in the rope
and reduce the likelihood of injury or damage.
Used when your rope isn’t long enough to reach the recovery anchor point, extension
straps are made from polyester webbing and come in various lengths and load ratings to
suit varying recovery situations.
Designed to spread the load of the recovery across two points on the vehicle requiring
assistance. Can be used in both Snatch Strap or Winching recoveries.
Only bow shackles that are load rated should be used for vehicle recovery. Load ratings
are visible on the shackle and will be in the form of WLL (working load limit) or SWL (safe
working load). The shackles, or any other recovery equipment, used should be sized
correctly for the winching task.
Winching Procedures
Clutch Operation
Familiarise yourself with the clutch operation. The clutch handle either “Engages”
the winch for operation or “Disengages” the winch for free spooling of the rope. The
clutch must always be “Engaged” before operating the winch under power.
Powering Out (No Load)
The unique Proportional Brake in the REVO winch allows for effortless powering OUT
under NO LOAD, with no concern for damage occurring to the brake or motor. In
some circumstances powering out the rope may be quicker and easier than free
spooling by hand.
Powering Out (Under Load)
It is not recommended to power OUT the WITH LOAD for longer than 30 seconds.
Exceeding this time will cause high amounts of wear to the friction brake.
1) To disengage, turn the clutch handle 90° in a clockwise direction to the
“Disengaged” position. The rope can now free spool off the drum.
2) To engage, turn the clutch handle 90° in a counter-clockwise direction to the
“Engaged” position.
3) If the clutch handle cannot be properly locked in the “Engaged” position, rotate
the drum to help the clutch device engage the gear train.
4) Wear appropriate gloves and use a pull strap when guiding the rope off the drum.
5) Never disengage the clutch while the rope is under load. The clutch handle must be
returned to the “Engaged” position before winching.
