Wheel-lift towing is a method used to transport vehicles by lifting only the front or rear wheels off the ground. This technique is commonly employed by tow trucks to move disabled or illegally parked cars without needing to lift the entire vehicle. The wheel-lift system consists of a metal arm that slides under the vehicle and raises it using hydraulic power. This allows for easier maneuverability and reduces the risk of damage to the towed vehicle. Wheel-lift towing is often preferred for its efficiency and effectiveness in various towing situations.
