A 4×4 wrecker is a kind of truck used to tow disabled vehicles or otherwise move heavy vehicles that cannot run on their own. The purpose and design of the 4×4 wrecker can vary, though all will have four-wheel drive capabilities that allow it to function on treacherous terrain or in bad conditions. Some wreckers like car wreckers Wellington will feature a long boom arm that operates in union with a winch system to haul up vehicles, while other wreckers may trait a flatbed that may tilt downward toward the land so a vehicle can be hauled onto it. This structure also uses a winch to haul vehicles.
Bigger vehicles, such as full-size lift up trucks, tractor trailers, some RV campers, and buses frequently cannot be towed with minor tow trucks. A 4×4 wrecker is typically required to shift such vehicles when they become disabled, though the largest wreckers may not be four-wheel make at all. The leading wreckers can feature three axles with up to ten wheels for added stability and torque. A 4×4 wrecker will usually have two axles, through three-axle trucks with only two drive axles are possible.
If the 4×4 wrecker features a rumble arm, that boom may be able to turn so disabled vehicles off the side of the road can be right or else hauled back onto the road. Whilst not generally common on these machines, outriggers may be there on the sides of the wrecker to promote extra lateral steadiness if the vehicle to be towed cannot be positioned straight behind the wrecker. These armaments will be controlled by hydraulic cylinders that will extend the arms down until they rest on the ground. A winch system will be mounted close to the cab of the wrecker, and the cable from this winch will run up and over the boom arm so it may be connected to the disabled vehicle.
A flat bed 4×4 wrecker shall not feature a boom arm, however instead a flat bed that could be moved in such a way that the back of the bed tilts down toward the ground. The vehicle to be hauled could be positioned after the bed, and a winch cable can be secured to the vehicle’s undercarriage. As the cable pulls on the vehicle, it shall go forward onto the bed, which could be righted gradually into the horizontal position. The disabled vehicle will then basically ride allied on the wrecker.
