How to choose a road wrecker
, then you must clearly know what your wrecker
is used for, and it must be selected according to the actual use environment. Different work environments determine the choice of wrecker
. For example, if you need to lift a troubled car that rolls into a ditch during rescue, then you need a flatbed wrecker with
a strap. When buying road wreckers,
you should also pay attention to the following two points:
Choose the size of the wrecker
, 3 tons, 4 tons, 8 tons, 16 tons, 20 tons, etc.
The requirements for the configuration of the wrecker are
different for different work environments. It is also an expressway. In some sections, there is a larger flow of medium-duty trucks and coaches, while others are more heavy-duty trucks. In this regard
, the configuration of wreckers
should be different. The former should be equipped with more medium and heavy-duty wreckers
and devices capable of removing buses, and the latter should be equipped with super heavy-duty wreckers
. It is also the traffic police department in urban areas. In some places, more illegal motorcycles need to be cleared, and in some places more illegal cars need to be cleared. In this regard, the former should be equipped with a motorized lifting platform type wrecker
, and the latter should be equipped with a clamp type wrecker
According to the provisions of the new standards for wreckers
, the maximum lift weight and the maximum pull weight are important technical parameters for measuring the work capacity of the wrecker
. The maximum support weight of the wrecker
must not exceed the maximum total design weight of its chassis. Maximum lifting weight refers to the rated lifting weight of the wrecker
when the effective length of the lifting arm is the minimum value. It must meet the requirements of "when the wrecker is pulled
, the front axle axle load is not less than 15% of the maximum total mass. The axle load of the axle must not exceed 20% of its allowable load; the front axle axle load must not exceed its allowable load at no load. "The ratio of the lifting mass to the dragging mass of the wrecker
is not less than 20%. According to these regulations, it is possible to identify whether the technical parameters marked by the manufacturer for the wrecker
are true and whether they comply with the standards for wreckers
The maximum lifting quality of a wrecker
is one of the important parameters to measure the technical performance of the wrecker
. QC / T 645-2005 standard stipulates "maximum lifting weight: rated lifting weight of the wrecker
when the effective length of the supporting arm is the minimum", and "under the maximum holding state, the rear axle load must not exceed its allowable 20% of load. " This is to calculate the maximum lifting weight of the wrecker
according to the rear axle condition. The overall arrangement can be reasonably arranged, and a weight can be added to the front of the wrecker
chassis to improve its maximum lifting weight.
The standard configuration
The standard configuration refers to the configuration required for the wrecker to normally complete the clearance operation requirements within a certain range; the optional configuration means that the user can purchase some parts to replace the original standard accessories, or purchase other parts to expand The working range of the wrecker
. For example, the hydraulic system has imported parts and domestic parts for optional selection; optional auxiliary wheels or other operating accessories to increase the operating function.
The engineering yellow wrecker truck
is very popular in the market, and the reason lies in its color. The important role of the engineering wrecker truck is
that his color is very eye-catching, especially when it is snowing in the winter in the north, and when there are white clouds everywhere, the engineering yellow wrecker truck
shows his conspicuous Superior importance, at this time his safety is the most important. All the wreckers
have reflective signs, or they are installed with warning lights for safety. The engineering yellow wreckers
have this feature, and they are yellow on urban roads or other places. It represents rescue.
Highway companies are big consumers of wreckers
. After the opening of a highway, in order to ensure the smooth flow of highways, highway companies have to invest millions or even tens of millions of funds to purchase wreckers
. There are many types and sizes of wreckers
. How to choose and configure wreckers
reasonably to ensure efficient completion of wrecking tasks and cost savings? Due to work, the author often contacts front-line highway clearance workers. Through communication and reflections with them, the author has his own opinion on how to configure the road
with a road- breaker
. First, we have to understand the structure, function and characteristics of various types of wreckers
. According to the structure type, the wrecker truck
is generally divided into four series: separated lifting type, integrated lifting type, flat type and ordinary type. The suspension type includes two types of boom rotation and non-rotation. Separated support cranes and integrated lift trucks
are divided into light, medium and heavy according to their working ability. Generally, only the heavy-duty vehicles have the boom rotation, and the light and medium-duty trucks do not rotate. The flat-bed wreckers
are all light vehicles with only two tonnages, which are 3 ton and 5 ton.
The most obvious feature of the flat-bed wrecker
is that it can drag one to two, that is, two faulty / accident vehicles can be cleaned at one time, which is especially suitable for light-duty faulty vehicles. But its disadvantages are equally obvious:
There is no lifting capacity, and for faulty vehicles that slip off the road, only other helpers
or cranes are used to support it;
The winch speed of the flat plate is slow, and it takes a long time to drag the faulty vehicle onto the flat plate;
The support arm of the flatbed truck is limited by the structure. When it is flat, it cannot be lowered to the ground completely. It can only be lowered to a negative angle to extend and retract the support arm to hold the faulty / accident vehicle. In this way, for some faulty / accident cars with lower chassis, such as sports cars and some high-end cars, it is easy to bump the bumper of the faulty car when clearing the obstacle, causing secondary damage to the faulty / accident car.
The characteristics of the separate suspension type and the combined lifting type wrecker
are that they can be towed and hoisted, and the speed of lifting the vehicle is fast. When the support arm is flat, it can be completely lowered to the ground without hurting the faulty vehicle , There is no danger of causing secondary damage to the malfunctioning car.
There are a variety of vehicles on the highway, so when
you purchase a wrecker,
you have to buy a variety of different types and levels of wreckers
. Considering the tonnage, light, medium and heavy wreckers
should be equipped.
