How to buy a wrecker

How to choose a road wrecker , then you must clearly know what your wrecker is used for, according to the actual use of the environment to choose, the different working environment, decided that the selected wrecker is also different, For example, if you need to rescue a faulty vehicle that is turned to the ditch, you need to use a car with a flatbed wrecker. In the purchase of road wreckers should also pay attention to the following two points:

The types of wreckers were selected, one was a flat wrecker, one was a flat wrecker, two were a wrecker, a wrecker was removed, and a multi-purpose wrecker was used.

Choose the size of the wrecker, 3 tons, 4 tons, 8 tons, 16 tons, 20 tons and so on.

Different obstacle clearing environments have different requirements for the configuration of wreckers. The same highway, some roads, medium-duty trucks and long-distance bus traffic more, while others are more heavy-duty trucks. In this regard, the configuration of the wrecker should be different. The former should be equipped with a medium-heavy wrecker and a device capable of clearing large buses. The latter should be equipped with a super-heavy wrecker. The same traffic police department in the city, some places need to clear more illegal motorcycles, and some need to clear the more illegal cars. In this regard, the former should be equipped with a motorcycle lift platform type wrecker, and the latter should be equipped with a clamp type wrecker.

According to the new standard for wreckers, the maximum lifting quality and the maximum supporting quality are the important technical parameters for measuring the working ability of a wrecker. The maximum care quality of a wrecker must not exceed the maximum design mass of its chassis. The maximum lifting mass refers to the lifting lifting quality of the wrecker when the effective length of the holding arm is at a minimum value. It shall satisfy the requirement that the wagon of the front axle is not less than 15% of the maximum total mass after the wrecker is in the supporting state. The bridge axle load must not exceed 20% of its allowable load; the axle load on the front axle must not exceed its allowable load at no-load.” The ratio of the lifting mass of the wrecker to the quality of the support is not less than 20%. According to these regulations, it can identify whether the technical parameters marked by the manufacturer on the wrecker are true and whether it meets the wrecker standards.

The maximum lifting quality of a wrecker is one of the important parameters for measuring the technical performance of a wrecker. The QC/T 645-2004 standard stipulates that "the maximum lifting mass: the rated lifting mass of the wrecker when the effective length of the holding arm is the minimum", and "the axle load on the rear axle must not exceed its allowable value in the maximum holding state. 20% of the load." This is to calculate the maximum lifting quality of the wrecker according to the conditions of the rear axle. The overall arrangement can be rationally carried out. It is also possible to increase the weight of the wrecker's chassis to improve its maximum lift quality.

The standard configuration refers to the configuration required by the wrecker to meet the requirements for the clearance of the obstacle within a certain range. The optional configuration means that the user can purchase some spare parts instead of the original standard parts, or purchase some spare parts to expand. The wrecker's operating range. If the hydraulic system has imported parts and domestic parts for matching; optional auxiliary wheels or other operating accessories to increase operating functions.
