Qingdao York. Manufactured by Qingdao York transportation equipment Co., Ltd., it is an enterprise in China that introduces foreign production technology and equipment to produce and operate semi-trailer support bridges and related components. It mainly produces axle products of multiple models and specifications such as 8-20t support bridges, 40-80t rigid suspension (one line and two bridges), air suspension and automatic steering bridges, which have passed the national quality system certification of ISO / TS16949:2002.
With the continuous development of automobile axle industry, its industrial system has been relatively sound. It is understood that there are more than 200 axle enterprises nationwide. Among these enterprises, which are of outstanding quality, most popular and most popular with consumers?
The lifting system is controlled in the cab. The hydraulic oil is controlled by the proportional valve, and the oil pumped by the oil pump is evenly distributed to the lifting cylinder to lift the frame evenly. The working oil pressure of the lifting system and the steering system is generated by the same high-pressure oil pump.
Hydraulic platform transporter is a special vehicle equipped with hydraulic lifting equipment. It is suitable for transporting heavy goods, especially for transporting prefabricated sections on the road of hard Subgrade in shipyard. The transporter can drive under the jig frame supporting the load, raise the load through the lifting system, transfer to any designated place, and then put down the load without crane or other lifting equipment.
Many card friends who operate semi-trailer have this feeling. The problems such as large tire wear, unavailability and short service cycle of the third axle of trailer virtually increase the operation cost. Therefore, some enterprises have developed a special pneumatic steering axle for trailer. This pneumatic steering axle uses air pressure to control the steering angle of the axle.
I believe that many small partners must encounter a lot of confusion when buying tires. What kind of tires do you choose to buy? Can environmentally friendly tires really reduce fuel consumption? Can sports tires improve performance? Can the silent tire be silent? To understand this, we need to start with the tread pattern of the tire.
Clean the head of the traction pin, use a lifting hammer to mark on the ground based on the center of the traction pin, as shown in the right group of drawings. Check the sharp cone of the benchmark with the wheelbase, align the center point of the axle head end cover of 1 and 2 bridges, and mark the left and right center of the first bridge on the ground at the same position with a hanging hammer, as shown in the following figure.
According to the actual needs, prepare 15m steel tape, 3M tape, hanging hammer, wheelbase measuring post and other measuring tools, as shown in the figure. Park the semi-trailer on a flat cement ground, separate the tractor from the trailer, and adjust the outrigger to make the front and rear of the trailer basically flat.
It refers to the distance between the center of the traction pin of the semi-trailer and the centerline of each axle of the semi-trailer. The wheelbase, front and rear suspension and pin wheelbase of the vehicle are not only the basic parameters of the semi-trailer design, but also the parameters required by other control systems.
First of all, there are steel tire and vacuum tire, which are subdivided into a variety of models, and different models are suitable for different models. At present, the most common ones in the market are 11.00R20 steel tire and 12.00r22 5 vacuum tire is widely used in flower basket, standard vehicle, rollover dump and various dangerous chemical vehicles, of which 12.00r22 is more equipped for vehicles with good long-distance road conditions 5 vacuum tire, the pattern is mostly 3 or 4 parallel lines.
