A pull-back wrecker is a type of tow truck that features a retractable bed with rails, allowing vehicles to be transported entirely on the back of the truck. It is commonly used for personal vehicles but can also accommodate larger vehicles. There are three basic types of tow trucks, including wheel lift cranes, hook and chain cranes, and flatbed or rollback wreckers. Flatbeds are constructed with steel, aluminum, or other alloyed metals and include safety equipment, hydraulic mechanisms, and platform supports. Options such as rail design, deck size, deck material, and capacity vary by model and intended application.
A pull-back wrecker is a type of tow truck. Typically used to transport personally owned motor vehicles, a retractable wrecker truck features a bed with rails. The entire bed can be lowered hydraulically to ground level. The vehicles to be transported can be driven on the platform or pulled with a winch. After the vehicle is safely positioned, the platform is raised to the level of the crane chassis and locked into position, and the vehicle is secured for transport.
Although most commonly used for personal vehicles, a wrecking truck can be outfitted with a flatbed large enough to accommodate larger vehicles. Heavy duty diesel demolition trucks frequently carry large and heavy vehicles such as backhoe loaders, cranes, or other construction vehicles. Commercial transport vehicles may be transported for delivery or repair via a heavy duty wrecker truck. Tow trucks for transporting large vehicles are common, but the term “back-up wrecker” generally refers to emergency roadside recovery kits for personal motor vehicles.
In terms of roadside emergency recovery vehicles, there are three basic types of tow trucks. These types include wheel lift cranes, hook and chain cranes, and flatbed or rollback wreckers. Wheel lift cranes as well as hook and chain wreckers transport a vehicle by lifting the front or rear axle, leaving the remaining wheels on the ground to roll behind the truck.
Alternatively, a pull-back wrecker allows the transport of a vehicle entirely on the back of a tow truck. By removing the entire vehicle from the road, tow truck drivers and vehicle owners eliminate potential damage to the vehicle being transported. Drivers need not worry about low-slung bumpers, the need to disconnect driveshafts, or other factors that make towing via hook-and-chain or wheeled tow trucks less desirable.
Certain features are common to virtually all flatbeds. Construction materials for roofs, rails, and other items include steel, aluminum, or other alloyed metals. Most pullback wrecking vehicles include a diesel-powered cab with an extended chassis. Safety equipment, hydraulic mechanisms and platform supports are mounted on the chassis to optimize the stability of the crane when fully loaded.
Options such as rail design, deck size, deck material, and capacity vary by model, intended application, and user preference. The bed rails, the raised metal boards on each side of the bed, can be high, low, fixed, or removable, depending on the specific type of back-up wrecker. Additional features like winches also vary from wrecker to wrecker.
