How to pull yourself free Return to the top of the page
 
 
  • Sooner or later, every 4x4 driver gets stuck. When it happens, survey the situation, stay calm and be patient. It takes time to recover your vehicle safely.
  • In mud, snow and sand, the first thing to do is try to reverse out of the problem. Remember that there are two reverse gears in some 4x4s – High and Low. Sometimes using reverse in High Range will free a stuck vehicle, while using reverse in Low Range may just spin the wheels.
  • If this doesn’t work, try gently rocking the vehicle backward and forward by using a reverse and then a forward gear. Your passengers can help by pushing, but co-ordinate this effort so that you are not reversing when your help is pushing forward! Always be aware of your helpers’ whereabouts when they are near the vehicle.
  • The important thing to remember is, do not keep spinning the wheels when you are truly stuck. Spinning wheels will only dig the vehicle in deeper and make recovery more difficult.
 
 
What to do with one vehicle Return to the top of the page
 
 
 
  • When the vehicle is really stuck, the hard work begins, especially if you are travelling with only one vehicle. The first thing to do is to shovel away mud, earth, snow or sand from under the vehicle and clear a path in the direction of travel, so the tyres can get enough traction.
  • Carpet strips, floor mats, brush, rocks or, if you are desperate, clothing or sleeping bags, can be placed as traction aids under the tyres in the direction of travel. Tyre chains will help in snow and some types of mud.
  • If you still can’t get out, jack up the vehicle and fill the area under the tyres with sand, rocks, logs, brush, packed snow or a combination of these. If the jack sinks into the ground, use your 60cm square plywood section as a base. Do not crawl under a vehicle that is supported by a jack, as this can be very dangerous. If you get stuck on a rock, stump or log, the first thing to do is to survey the situation and figure out the best way to free the vehicle without damaging it. Take your time. If you are stuck on an object that can be moved, jack up the vehicle and clear away the obstacle. If the obstacle can’t be moved, jack up the vehicle and fill under the tyres so that you can drive over the obstacle.

  • If you are travelling with another vehicle, a recovery strap can be used to pull you out once a path has been cleared.
  • A recovery strap is made of heavy-duty nylon with an eye sewn into each end. Unlike a cable or chain, a recovery strap stretches like a rubber band. This cushions the initial force applied to the stuck vehicle. It also stores energy that is released when the stretched strap returns to its normal length. This extra stored energy allows a small vehicle to free a much larger vehicle.
 
 
Recovery strap tips and techniques Return to the top of the page
 
 
  • The strap must be in good condition – no cuts, frays or broken stitching.
  • Attaching points and their associated hardware on both vehicles must be strong enough to withstand the force applied to them. Attaching points must be secured to the vehicle’s frame.
  • Bystanders must stay clear.
  • The recovery vehicle should use an attaching point at its rear. This placement gives the driver more protection than would a windscreen if anything should come loose.
  • Remove obstacles such as rocks and logs that are in the recovery path.
  • Do not attach a strap in a way that allows it to become cut or chafed.
  • Use a strap with enough strength and one that is designed for this type of use. An 8cm x 9m strap is recommended.
  • Start out with a small amount of slack in the strap and a modest amount of acceleration when tugging on a stuck vehicle. Forces increase dramatically when the amount of slack in the strap and the tow vehicle’s acceleration increase.
  • Store nylon straps away from sunlight in a clean, dry condition.
 
 
Winching you way free Return to the top of the page
 
 
  • The best way to get unstuck is with a winch. A winch takes the hard work out of vehicle recovery, it allows a lone vehicle a means of freeing itself, and in some situations, a winch is the only tool that can be used to recover a vehicle.
  • Another vehicle can be used as an anchor, but natural anchors, such as trees, stumps and rocks, are the handiest. When no natural anchors are available, a spare tyre, log or any other similar object that can be partially buried can form an anchor.
  • Always select your anchor carefully to be sure it is strong enough to withstand the load. It may be wise to use several items and group them as a single anchor.
  • A chain or strap must always be used around the anchor to which the winch cable is attached. The winch cable should never be wrapped around the anchor and hooked back onto itself since this will damage the cable.
  • In most situations, assistance from the vehicle being recovered will be necessary. This will place less load on the winch and cause less drain on the battery in the case of an electric winch. This must be done very carefully. When driving and winching, you must not overtake the winch cable and allow the cable to become slack and feed loosely onto the drum or run over the cable with your wheels. In a vehicle equipped with a manual transmission, be careful not to slip and overheat the vehicle’s clutch.
 
 
Winching tips and techniques Return to the top of the page
 
 
  • Use your winch before you actually need it to become familiar with its operation.
  • Never attempt to operate a winch without wearing heavy leather gloves.
  • Never step over the cable, even when it is not under load.
  • Always stand clear of the cable and load during the winching operation.
  • While a remote-control lead is plugged into the winch, always keep clear of the drum, cable and rigging.
  • Keep helpers and spectators at a safe distance. If the cable pulls loose or breaks under load, it can suddenly lash back with tremendous force.
  • Never use the winch cable as a tow rope. A winch is not designed for this and a sudden jerk can snap the cable or damage the drum.
 
 
Anchoring and operation Return to the top of the page
 
 
  • Always use a tree strap when anchoring to a tree. Cables and chains can severely damage a tree. Never use a nylon strap to anchor around rocks.
  • When anchoring the pulling vehicle, apply the parking brake and blocks to the wheels. The foot brake will also provide additional holding ability over the parking brake.
  • Always unspool as much cable as possible when rigging. Double the line with a snatch block or pick an anchor as far away as practical. This will minimize cable damage, such as mashing and kinking, caused from top layers pulling down into the bottom layers when short pulls are made. The greatest pulling power is available at the first layer on the drum, decreasing with each successive layer.
  • Never winch with fewer than five turns of cable around the winch drum. With fewer turns, the cable may break loose from the drum under heavy load.
  • Always pull as straight as possible to minimise the build-up of cable on only one end of the drum.
  • Put a blanket or coat on the middle of the cable when winching. This will help slow the cable down if it breaks and prevent injury or damage. You can also raise the bonnet on the winch vehicle to protect the winch operation from a broken cable or attaching hardware.
 
 
Rewinding Return to the top of the page
 
 
  • Always inspect and carefully rewind the cable after use. Mashed, pinched or frayed areas severely reduce the original tensile strength. For safety’s sake, replace the cable when damaged.
  • Do not let the cable slide through your hands, even when wearing gloves.
  • At times, it may be necessary to temporarily respool the cable under no load after use. Hold the remote-control lead in one hand and the cable in the other. Start as far from the vehicle as the remote control will allow, activate the switch, walk in a metre of cable and release the switch. Repeat the process. Always release the switch when you are at least one metre from the winch. And always wear heavy gloves when handling the cable.
  • Always release the switch when the hook is a minimum of one metre from the winch. Place the hook on a suitable spot on the mounting kit. Then, keeping your hands completely clear of the hook, cable and winch, "jog" the switch intermittently to take up the slack. Do not over-tighten the cable or damage may occur.
  • When spooling the cable, be sure to distribute it evenly and tightly on the drum. This prevents the top layers of the cable from being drawn into the bottom layers and creating a bind.
 
All of this may sound tedious, but careful planning and slow, careful attention to detail will make vehicle recovery safe and relatively easy. But don’t wait until you’re in dire straights to try this out. Practise vehicle recovery with a friend so when an emergency comes, you're prepared.
