Off Road Rescue in Desert Rescue

Desert rescue is different from any other terrain - here, brute force often backfires, and delicate operation is the key to getting out of trouble. When the rear car is stuck in a sea of sand, the front car, as the rescuer, needs not only power, but also precise control over the sand, rhythm, and equipment.

Equipment List and Desert Adaptation

Low elongation trailer belt: desert specific type, elongation controlled within 3%, length 12-15 meters. A trailer belt that is too long will increase the difficulty of operation, while a belt that is too short will result in insufficient buffering

Forged shackles: at least two, with a working load of not less than 4.75 tons, check for sand particles stuck in the threads before use

Escape board: made of high-strength composite material, with a length of more than 1.2 meters and a longitudinal sand guide groove on the surface

Deflation tool and dual cylinder air pump: The quick release valve can instantly adjust tire pressure, and the high flow air pump ensures recovery after getting out of trouble

Sand shovel: Foldable aluminum shovel, wide shovel surface for quick sand cleaning

Step 1: Precise setting of dual tire pressure

The first thing the driver of the preceding vehicle needs to do after arriving at the rescue location is to confirm the tire pressure of both tires. The standard tire pressure for desert rescue is 0.8-1.0, but for the rear car that has already sunk, it can be further reduced to 0.6-0.8 to maximize the "spreading" of the tires and increase buoyancy. Keeping the front car at 0.8-1.0 is sufficient, as low tire pressure during towing may cause the tire to detach.

Step 2: Rapid Diagnosis of Trapped Vehicle Attitude

Make a circle around the rear car and complete three judgments: first, the depth of sinking, the height at which the tire is buried; The second is to support the bottom, whether the chassis has come into contact with the sand surface; The third is the orientation of the front of the car, which is the angle with the expected drag direction. If the chassis is supported by the bottom, it is necessary to clean the sand first - use a sand shovel to dig out the sand from the bottom of the vehicle, dig out two shallow grooves extending from the front of the tires, and reserve acceleration channels for starting.

Step 3: Laying the T-shaped escape board

Lay two escape boards in a zigzag pattern in front of the rear tires, with the tips pointing towards the direction of the escape. This layout allows the wheels to gradually gain traction when starting, rather than simultaneously contacting the sand plate causing slippage. The end of the escape board should be buried below the sand surface and level with the surrounding sand surface to prevent it from being pushed away by the wheels when starting.

Step 4: Establishment and Calibration of Traction Line

Choose a straight back approach for the front car to approach the rear car, avoiding increasing the subsequent drag angle due to lateral approach. The connection between the tow hooks of two vehicles should be aligned with the direction of the front of the rear vehicle, with an angle not exceeding 10 degrees. If there is an angle deviation, the front car needs to readjust its position instead of forcibly pulling diagonally - diagonal force can cause the rear car to sway or even roll over.

Connection sequence: First, install the release buckle on the trailer hook of the front vehicle, then insert it into the trailer strap, and finally connect it to the rear vehicle. After tightening, the pin shaft of the release buckle can be fixed by wrapping it with tape to prevent sand and dust from entering the thread and causing it to get stuck under stress.

Step 5: Establishment of cable flags and observation posts

Hang the cable flag or heavy jacket at the midpoint of the trailer belt, slightly towards the front side of the vehicle, so that it is about 30 centimeters off the ground. Arrange an observer to stand 10 meters behind the front side of the vehicle, so that they can see the status of both vehicles at the same time and avoid the rebound zone of the trailer. The observer holds a walkie talkie and is responsible for monitoring the tension of the trailer belt and changes in the posture of the rear vehicle.

Step 6: Equipment recovery and inspection after being rescued

After the rear car reaches a solid sandy surface, the two cars should not stop immediately, but continue to move forward to a completely flat area. After coming to a complete stop, first disconnect the trailer strap and check for sand particles embedded in the soft eyes that may damage the fibers. To remove the buckle, use an air gun to blow away the sand and dust inside the thread, and apply a small amount of lubricant. After pulling the sand board out of the sand, strike it to shake off the sand particles and prevent residual gravel from scratching the board surface.
