The Scenario usage of Road Wrecker

Wrecker refers to a special vehicle equipped with road emergency operation equipment. Because the car is driving on the road, the breakdown and accident is inevitable, especially on the high-grade highway, this phenomenon often happens. The task of the wrecker is to drag the broken car or accident car away from the scene in time to ensure that the road is unimpeded. Therefore, the road wrecker is also known as the road rescue vehicle. With the increase of high-grade roads and cars in use, wreckers have also been developed.

Road Wrecker classification

Road Wrecker is a special engineering vehicle designed to ensure the smooth road, and is an important equipment for traffic management in bustling urban areas and expressways. It can quickly, timely and safely remove accidents, failures, illegal vehicles on the road, and special vehicles that divert road traffic.

First, according to the structure type, the road wrecker is generally divided into four series of crane separation road wrecker, crane joint type wrecker, flat type road wrecker and ordinary type. The crane separation road wrecker includes two types: the boom rotating road wrecker and the non-rotating road wrecker.

Second, people often say that 3 tons of road wreckers, 5 tons of road wreckers, 8 tons of road wreckers, 20 tons of road wreckers and other specifications of road wreckers, in fact, refers to the level of the bearing capacity of the chassis used by the road wrecker. It has a certain relationship with the total mass of the towed vehicle in terms of capacity, but there is no necessary connection, and the larger the tonnage, the greater the operation capacity of the road wrecker.

Third, when the road wrecker clears the vehicle to be supported (towed) from the scene, it generally adopts two methods: towing and towing. Pulling is to use the arm of the road wrecker to be lifted by the truck and to pull. Towing, which is often referred to as hard towing, is the use of the road wrecker to be hard-connected to the trailer.

Repair and maintenance of road wrecker

The road wrecker is mainly composed of chassis, lifting device, lifting traction device, hydraulic system, electric control system, car body and toolbox, etc., with lifting, pulling and lifting traction and other functions, suitable for highway, urban road clearing operations.

The road wrecker is a special engineering vehicle designed to ensure the smooth flow of roads, and is an important equipment for traffic management in bustling urban areas and expressways. It can quickly, timely and safely remove accidents, failures, illegal vehicles on the road, and special vehicles that divert road traffic.

First, according to the structure type, the road wrecker is generally divided into four series of crane separation road wrecker, crane joint type wrecker, flat type wrecker and ordinary type. The crane separation road wrecker includes two types: the boom rotating wrecker and the non-rotating road wrecker.

Second, people often say that 3 tons of road wreckers, 5 tons of road wreckers, 8 tons of road wreckers, 20 tons of road wreckers and other specifications of road wreckers, in fact, refers to the level of the bearing capacity of the chassis used by the road wrecker. It has a certain relationship with the total mass of the towed vehicle in terms of capacity, but there is no necessary connection, and the larger the tonnage, the greater the operation capacity of the wrecker.

Third, when the road wrecker clears the vehicle to be supported (towed) from the scene, it generally adopts two methods: towing and towing. Pulling is to use the arm of the wrecker to be lifted by the truck and to pull. Towing, which is often referred to as hard towing, is the use of the road wrecker to be hard-connected to the trailer.

Among them, the supporting capacity of the road wrecker must meet the following two conditions:

1. The lifting weight of the bracket is not greater than the rated lifting mass of the road wrecker, and with the extension of the bracket, its lifting weight will gradually decrease.

2.the rated holding mass shall not exceed its maximum total mass. That is, the total mass of the vehicle to be towed shall not exceed the maximum total mass of the road wrecker. For example, the 5140TQZ road wrecker, when supporting, the total mass of the vehicle to be supported shall not exceed 14 tons at first, and it depends on whether the weight of the lifting point of the bracket is within the rated lifting mass range. The towing capacity of road wrecker is related to the maximum total mass and engine power of road wrecker. Article 3.6 of GB7258 "Motor Vehicle Operation Safety Technical Conditions" stipulates that the specific power of the motor vehicle should not be less than 4.8kW/t, and the tow capacity of the wrecking vehicle should meet this requirement.

For example, a 5140TQZ road wrecker, its maximum total mass G=14000kg, the engine power is 132 kW, then the tow mass G* of the wrecker must meet: G+G*≤ 132/4.8x1000, that is, G*≤ 13500kg. It can be seen from the above results that because the chassis design takes into account the match between the load and the engine, the tow and support capacity of the modified road wrecker is basically the same. For safety, it should be used in accordance with this regulation.

Fourth, the operation and use of the car, precautions and other use and extend the service life of the road wrecker.

With the rapid development of China's economy, highway construction by leaps and bounds, mileage continues to increase, China's "five vertical and seven horizontal" highway trunk will be basically completed.

However, it is difficult for the existing road wrecker to complete the hauling and clearing, which seriously affects the traffic. Some wrecker manufacturers hope to solve this problem by increasing the chassis tonnage, but the ability to improve is limited, and the car price has increased several times, affecting the economic benefits of users. Therefore, the market calls for wreckers with large lifting and holding capacity.

How to buy a road wrecker

How to buy road wrecker must be selected according to the actual use of the environment, wrecker attention is suitable for auto repair shop wrecker and traffic department use, traffic wrecker suitable for work needs to meet the needs of the product is a reasonable choice. The purchase of road wrecker should pay attention to the following points:

1.according to the requirements of cleaning operations

Determine the types of road wrecker, and the configuration requirements of wrecker are different in different road wrecker operating environments. The same is the highway, in some sections, the flow of medium trucks and coaches is larger, and some are more medium and heavy trucks. In this regard, the configuration of the road wrecker should be different, the former should be equipped with more medium and heavy road wrecker and with the device that can remove the bus, the latter should be equipped with super heavy road wrecker. The same is the urban traffic police department, some places need to remove more illegal motorcycles, and some need to remove more illegal cars. In this regard, the former should be equipped with a motorcycle lifting platform type wrecker, the latter should be equipped with a jig type road wrecker.

2. Technical parameter standard

According to the new standard of road wrecker, the maximum lifting quality and maximum pulling quality are important technical parameters to measure the working ability of wrecker. The maximum towing mass of the road wrecker shall not exceed the maximum total design mass of its chassis. The maximum lifting mass refers to the rated lifting mass of the wrecker when the effective length of the bracket is the minimum value, which must meet the requirements of "the wrecker in the supporting state, the axle load of the front axle shall not be less than 15% of the maximum total mass, and the axle load of the rear axle shall not exceed 20% of its allowable load; The axle load of the front axle shall not exceed its allowable load when unloaded." The ratio between the lifting mass and the pulling mass of the wrecker is not less than 20%. According to these provisions, it can identify whether the technical parameters marked by the manufacturer for the road wrecker are true and whether they meet the wrecker standards.

The maximum lifting quality of road wrecker is one of the important parameters to measure the technical performance of wrecker. The QC/T 645-2004 standard stipulates "Maximum lifting mass: the rated lifting mass of the wrecking vehicle when the effective length of the bracket is the minimum value", and "in the maximum holding state, the rear axle load shall not exceed 20% of its allowable load". This is according to the rear axle conditions to calculate the maximum lifting mass of the wrecker, can be reasonable overall layout, can also increase the weight in the front end of the wrecker chassis to improve its maximum lifting mass.

3.standard configuration and optional configuration list

The standard configuration refers to the configuration required for the Dongfeng road wrecker to complete the requirements of the clearance operation normally within a certain range; Optional configuration means that the user can buy some parts to replace the original standard parts, or buy some other parts to expand the scope of operation of the wrecker. If the hydraulic system has imported parts and domestic parts for selection; Choose job training wheels or other job accessories to increase job functions.
