Snatch Straps and how to use them
A
snatch
strap is a piece of equipment used to help in the recovery of
vehicles bogged in sand or mud. Snatch straps are manufactured from
webbing that is capable of approximately 20% stretch under load.
When
stretched, the strap effectively stores kinetic energy released by the
momentum of the recovery vehicle. The resultant force is much greater than
using a non-expanding towing rope, when the strap returns to its normal
length. The snatch
strap allows even a small vehicle to recover a much bigger vehicle
in a recovery situation.
A
snatch
strap is used by attaching one end to a rated recovery
point on the bogged vehicle (e.g. a recovery hook or loop on the
chassis). A second vehicle is required to do the recovery. The snatch
strap is laid out on the ground in the direction the bogged vehicle
is to be recovered (either forwards or backwards), with an "S"
bend in the middle approximately 1m in length. The recovery vehicle is
backed up so that the snatch
strap can be attached to a second rated recovery point on the rear
of the recovery vehicle.
All
passengers and bystanders should stand completely clear of the recovery
operation at all times. Once a snatch
strap is connected to both vehicles, it is viewed as
"live" and nobody should be allowed to step over it at any time.
The
snatch
strap should also never under any circumstances be attached to the
towbar of the recovery vehicle. The actual tow-ball could break off and
become a fatal bullet to bystanders or the driver of the bogged vehicle.
Bullbars
are not suitable as mounting points for a recovery operation either. The
golden rule is that your mounting point should also be directly part of
the chassis of both vehicles, a 4x4intelligence recovery
point is perfect.
First
attempt a simple tow of the vehicle using the snatch strap. If the towing car does not succeed in freeing the stuck
vehicle then try again, this time leave two metres of slack in the snatch
strap, before attempting the recovery. Any rocks, tree trunks or
obstacles in the recovery path should be removed beforehand.
The
front vehicle should then accelerate at moderate speed.
As the driver accelerates they will feel the snatch strap take up
the slack and then begin to stretch.
Often the front vehicle will then come to a halt and the elasticity
of the strap will come into effect and slingshot the rear vehicle out of
the hole. When
"snatching" a stuck vehicle, using preferably low range second
gear. The driver of the stuck vehicle should engage the same gear and be
ready to release the clutch when the strap is taking up the slack.
If
this fails to recover the stuck vehicle, repeat the procedure, but this
time marginally increase the acceleration speed of the recovery vehicle.
Failing
which, increase the amount of slack to 3 metres in the snatch
strap!
If
the recovery vehicle cannot be brought close enough to the stuck vehicle,
for fear of getting bogged down as well, two snatch straps may be
connected to each other.
The
only safe technique for joining snatch straps is to thread each strap
through the eye of the other strap, if you consider the number 69 as the 2
straps, each showing one eye, the tail of each is passed through the eye
of the other.
Something light, even a rolled up newspaper, is then put between
the straps as they tighten down on each other so you prevent them binding
together when used.
Never
use a "D" shackle to connect two snatch straps. It could turn
into a lethal missile under strain.

straps.
