| Personal safety and the protection of property are paramount when considering 4WD recovery. • Never attempt to recover a vehicle without all the necessary equipment. • Only use equipment that is properly rated and in serviceable condition. If in doubt, don’t use it. • Ensure that only the people required for the recovery are present. All spectators should be kept at a safe distance. • Ensure that there are good communications maintained between participants and bystanders at all times. This is best achieved by use of UHF radio. ARB straps come in a range of high visibility safety colours. Different strap types are instantly recognisable and come with warning tags that include information such as strap type, rated capacity, material type and precautions. Due to the nature of synthetic fibres, recovery straps require rest periods between use to return to their original length and capacity. Be aware that excessive pulls on a recovery strap over a short period of time can cause build up of heat and possible failure. Always consider your impact on the environment. As responsible 4WDers we are charged with caring for the areas we visit. During wet periods, 4WDs can have a devastating effect on our tracks. Long term damage can result in temporary or even permanent track closures. Before travelling, obtain a list of road closures from the relevant conservation and environment office. If while 4WDing you come across an obstacle, consider a minimum of attempts at passing before trying to recover the vehicle. Excessive wheel spin can cause damage to both the track surface and vehicle components. It is important to ensure that only correctly mounted and rated recovery points are used for vehicle recoveries. Check your vehicle manufacturers hand book for recovery point locations. Tie down points are not suitable for vehicle recovery so aftermarket recovery hooks should be sourced. Do not use a tow ball or tie down point as a recovery point. Tow balls are not made of high tensile material and have been known to fail from stress, with the potential to become lethal missiles. If you are unsure of the type of recovery points on your vehicle, consult the manufacturer. A recovery damper is a device that has been designed to restrict the whipping action of a strap or winch cable in the event of failure, therefore reducing the possibility of vehicle damage and personal injury. The recovery damper should be fitted to the middle third of a strap or winch cable. 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). Shackles with a rating of at least 3.25t should be the minimum and are suitable for attaching one end of a strap. 4.75t rated shackles have a larger eye and are more suited to applications such as tree trunk protectors where two ends of the strap are fitted in the shackle. Never over-tighten the shackle pin. Forces exerted on the shackle by vehicle recovery can cause the pin to seize. The correct method is to tighten the pin until it seats, then back off the pin approximately half to one full turn. A snatch strap, as the name suggests, is used to “snatch” a vehicle that can no longer maintain forward momentum under its own power. ie. bogged or unable to climb due to loss of traction, swamped in a water crossing, stuck on an obstacle or loss of power. A snatch strap is an elastic recovery device that stores kinetic energy and has the ability to stretch to a significant degree and return to its original length. This elasticity combined with the momentum of the recovery vehicle creates a “snatching” effect that can extract a vehicle from the most precarious positions without shock loading the vehicle or attachment points. When choosing a snatch strap for use, it is recommended that the strap has a minimum breaking strength (MBS) of between two to three times the vehicle’s gross vehicle mass (GVM). When using a snatch strap to recover a stranded vehicle the MBS should be suited to the GVM of the lighter of the two vehicles involved in the recovery process. If the GVM is not stated on the identification plate or registration certificate of a vehicle, it could be available from the owner’s handbook, or consult the vehicle manufacturer. It is important that the correctly rated snatch strap is used. If a strap with a too heavy breaking strength is used on a light vehicle, the desired stretch may not be achieved and more stress will be placed on the recovery points. Persons intending to use the strap should consider completing a nationally recognised 4WD training course or contact a 4WD club for comprehensive advice on the proper selection and use of the strap. • The strap must not be used for lifting or conventional towing. • Persons intending to use the strap must ensure that the strap is not damaged and in a usable condition. • The strap’s strength and stretch are reduced when the strap is saturated • A recovery damper, heavy bag or blanket must be draped over the strap during use to reduce any unintentional rebound of the strap. While a recovery is being performed, only the persons involved in the recovery should be in either of the vehicles. All other persons should be situated outside the motor vehicles and be kept at a safe distance (recommended as at least 1.5 times the length of the un-stretched strap) from either of the vehicles involved in the recovery process and to the side of the line of the recovery. • Never get in the way of the vehicle performing the recovery! Only attach the strap to a vehicle recovery point or device that is suitably rated for use with the strap. Incorrect use has previously resulted in serious injury and death. The method for using a snatch strap is quite simple; however improper use can cause serious damage or injury. • The recovery vehicle should be placed within reach of the snatch strap and if possible directly in line with the direction of pull. If this is not possible due to insufficient length, two straps may be joined using the correct method. Never join snatch straps with a bow shackle, as this may become a lethal missile in the event of strap breakage. |
• The strap should be unrolled and connected to a secure recovery point on each vehicle ensuring that the strap is not twisted. Approximately 2-3 metres of slack strap should left be between the vehicles. Do not connect to a tow ball or tie down point. |
