The wrecker truck is mainly composed of: chassis, lifting device, lifting traction device, hydraulic system, electronic control system, truck body and toolbox, etc. It has many functions such as lifting, pulling and lifting traction, suitable for highways and urban roads.

The purpose of the wrecker truck

Wrecker tow trucks are special engineering vehicles designed to ensure smooth roads, and are important equipment for traffic management in prosperous urban areas and expressways. It can quickly, timely and safely remove accidents, breakdowns, and illegal vehicles on the road, as well as special vehicles for dredging road traffic.

First, the wrecker trucks are generally divided into four series according to the structure type: the separate type wrecker truck, the combined type wrecker truck, the flat type wrecker truck, and the ordinary type. Among them, the lifting and separating type wrecker includes two types of boom rotating wrecker and non-rotating wrecker.

Second, people often say that the wrecker trucks of 3 tons, 5 tons, 8 tons, 20 tons, etc., actually refer to the chassis used by this type of wrecker. level of carrying capacity. It has a certain relationship with the total mass of the towed vehicle in terms of capacity, but there is no necessary connection. The larger the tonnage, the larger the operating capacity of the wrecker.

Third, when the wrecker truck clears the towed vehicle away from the scene, two methods of lifting and towing are generally used. Lifting is to use the support arm of the wrecker to lift the vehicle and tow it. Towing is what people often call hard towing, which is to use a wrecker to drive the car hard-connected.

The towing capacity of the wrecker must meet the following two conditions.

1. The lifting weight of the supporting arm should not be greater than the rated lifting weight of the wrecker, and as the supporting arm is extended, the lifting weight will gradually decrease.

2. The rated support mass shall not exceed its maximum total mass. That is, the total mass of the towed vehicle shall not exceed the maximum total mass of the wrecker. For example, when the 5140TQZ wrecker is towed, the total mass of the towed vehicle must not exceed 14 tons first, and it also depends on whether the weight of the arm lift point is within the rated lift mass range. The towing capacity of the wrecker is related to the maximum total mass and engine power of the wrecker. The specific power of the motor vehicle should not be less than 4.8kW/t, and the towing capacity of the wrecker should meet this requirement.
