Equipped with lifts, towing, lifting and other devices, it is used for the removal of vehicles with road obstacles. The removal and rescue of motor vehicles is the process of moving the accident or troubled vehicles to the place where they are sent (roads, roadbeds, subgrades, etc.) quickly, safely and without damage, to the repair shop or parking lot. The assistance and rescue services provided by members and vehicles are also effective ways to ensure the smooth flow of road traffic.
Second, the development of wreckers
The road-removal and rescue technology originated in the United States in the early 20th century. In the early days, accidents or troubled vehicles were pulled by truck wire ropes or hard tow bars. This beginning, the history of the wrecker development began.
The first stage 20-50 years in the 20th century, installed pulleys, rope and winch on the truck, driven by mechanical transmission windlass, supported by the tie rod end failure to lift the car off the scene, a single function.
second stage In the 50s and 70s of the 20th century , it was marked by the introduction of hydraulic transmission and control technology. Along with the production of the first batch of wreckers using full hydraulic transmission, a number of well-known wrecker manufacturing companies emerged. The process technology of the wreckers at this stage has been greatly developed. First, the series of varieties and specifications have increased, and the structural forms have been diversified, followed by the special chassis and the diversification of the second chassis.
The third phase Is so far in the 1980s, a period of rapid development wrecker, wrecker main features of this stage is diverse structural, functional and has a lift, lift, drag, pull, drag back and other functions.
Third, the classification of wrecker
Divided by categories: drag and drop Siamese type, drag and drop separation type, flat dragging a type of two, 360- degree rotating hanging type , hydraulic automatic clamping type.
According to the structure can be divided into: haulage, loading, lifting, rescue ( single-arm and double-armed ) type of wrecker.
Divided by operating ability: light, medium and heavy and super heavy. Lightweight obstacle-ridden countries operate on light trucks, minibuses and cars. Medium- and heavy-duty wreckers are targeted at heavy-duty trucks, large and medium-sized passenger vehicles, etc. Super-heavy wreckers target heavy-duty trucks. Cars and super heavy semi-trailer series.
Wreckers can be classified into carrying and hoisting traction according to their characteristics. The type of vehicle is to take the damaged vehicle to the carrying vehicle and transport it; the lifting and traction type is to use the lifting and traction device installed on the vehicle to lift ( or lift ) one end of the damaged car off the ground and the other end still touches the ground, and then lifts the vehicle. Traction wreckers dragged off the scene.
