Introduction To The Characteristics And Functions of 4 × 4 Off-road Trailer Accessories

A complete set of towing and rescue equipment is crucial in off-road driving, long-distance crossing, or rescue scenarios. The following is an introduction to commonly used trailers, rescue accessories, and their functions for 4x4 off-road vehicles, helping car enthusiasts cope with various complex road conditions.

Shackle Hitch Receiver

Function: Used for rigid towing vehicles, suitable for road towing or short distance rescue, providing stable straight-line traction.

Features: Adjustable length or foldable design for easy storage.

Applicable: Towing of unpowered vehicles (such as malfunctioning or accident vehicles).

Attention: It is necessary to match the vehicle towing hook interface to avoid damage caused by uneven force.

Trailer Shackle

Function: Connect trailer ropes, pulleys, or other rescue equipment to enhance the flexibility and safety of the towing system.

Type: D-type Shackle: High strength, versatile, suitable for most rescue scenarios; Bow shackle: with a larger opening for quick installation; Soft shackle: lighter and faster to install.

Specification: Common load-bearing levels: 4.75 tons, 9.5 tons, to be selected according to rescue needs.

Attention: The bolts must be tightened during use to avoid danger caused by loosening.

Trailer Snatch Block

Function: Change the direction of force applied by the trailer rope to achieve multi angle rescue (such as lateral towing). By using pulley systems, mechanical advantages can be increased, single point forces can be reduced, and drag efficiency can be improved.

Applicable scenario: When the vehicle is stuck in a deep pit, mud or sand and needs to change the traction direction.

Material: High strength aluminum alloy or steel, ensuring wear resistance and impact resistance.

Kinetic Rope

Function: Elastic buffering traction, suitable for dynamic rescue (quick towing in the moment of getting stuck).

Specification: The length is usually 8-10 meters and the load-bearing capacity is 5-10 tons.

Attention: Avoid tying knots on the trailer rope to prevent local force breakage.

Tow Strap

Function: Wide width design, disperses tension, reduces damage to trailer hooks, suitable for static towing.

Advantages: More wear-resistant than trailer ropes, suitable for complex terrains such as sand, gravel, and mud. Can be used with a detachable buckle to improve connection security.

Hitch Tightener

Function: Used to secure shackle hitch receiver, frames, or suspension components, providing high-strength mechanical connections.

Common use: Reinforce trailer hook installation points. Steel plate springs or suspension systems for securing off-road trailers.

Specification: The appropriate size should be selected based on the bolt diameter and load-bearing capacity.

Farm Jack

Function: Lift the vehicle for easy release or tire replacement, especially suitable for soft ground.

Caution: Ensure the ground is stable and avoid danger caused by vehicle sliding.

Traction Board

Function: Provides temporary grip to help the vehicle break free from mud, sand, or snow.

Usage: Place the escape board under the pulley wheel, slowly refuel and drive out.

Safety Tip:

○All accessories must be checked for rated load to avoid exceeding the limit of use.

○During dynamic rescue, personnel should stay away from the rebound range of the trailer rope.

○Regularly maintain equipment to prevent rust or wear from affecting strength.

This complete set of towing and rescue equipment can keep the 4x4 off-road vehicle maneuverable and safe in various harsh environments, making it an essential rescue tool for off-road enthusiasts!
