Suspensions of Trailer-manufacture,factory,supplier from China

1. Introduction the present situationWith the improvement of the highway and its infrastructure and the rapid development of the national economy, the demand for semi-trailer with high transport efficiency is growing rapidly in recent years.Among the components of the semi-trailer, the tire is the only component of the vehicle that directly contacts the road surface.

1. ChassisThe frame is mainly composed of girder - welded I-beam, support beam, connection beam, side beam, lock, traction pin connection device, panel, etc.The side beams are generally channel steel or bending pieces. At present, most trailers use channel steel. There will be more side beams for bending pieces with light body, because the requirements for strength are not too large.The supporting beam is the crossing beam, and now most of them are W beams. 2.  Upper bodyFor side wall trailers, the bodywork part refers to railings, gantries, etc.

1. Vehicle maintenance specification2. Weekly or routine inspection before each transportation (operated by the user) The following safety inspections must be carried out every week or before each transportation:A Check the tyre pressure and adjust it to the level recommended by the tyre manufacturer;B Check the tightness of tire screws;C Check the brake system for air leakage and test whether it can brake; D Check the tightness of all nuts, screws and bolts for suspension; E Check the braking connection of tractor and semi-trailer; F Drain the air reservoir and a

Semi-trailer can transport large volume, and not easy to split large construction machinery, commercial goods, containers, can also transport vegetables, fruits, meat and other packaged fresh items, with good compatibility and speed.1. Intelligent interconnection of logistics vehiclesSemi - trailer intelligent interconnection is the trend.

There are several advantages of using fence semi trailers for transportation and storage purposes. Some of the key advantages include:Versatility: Fence semi trailers offer great flexibility in terms of freight and cargo management. The fence sides can be easily removed or adjusted, allowing for easy loading and unloading of various types of goods. It can accommodate oversized and irregularly shaped items, making it suitable for a wide range of industries.Security: Fence semi trailers provide enhanced security for transported goods.

The lower the center of gravity of the lowbed semi-trailer, the better the stability and safety, the stronger the ability to transport ultra-high goods and pass overhead obstacles, the application of lowboy semi-trailer is extensive, the application of lowbed semi trailer is briefly explained below.Lowbed semi-trailer has a wide range of applications, suitable for heavy vehicles, low boy semi-trailer frame cargo table is relatively low, so it has safety during transportation to ensure that the transportation is stable enough.The lownbed semi-trailer walking structure is made of high-strength i

When there is an electrical fault in the oil tank trailer, it is an important prerequisite for maintenance to quickly and accurately judge the fault. After a lot of practice and research for a long time, the maintenance engineers have realized that the following methods are very practical in electrical diagnosis.Observation methodIf the starter of the ofuel tanker trailer cannot be started, turn on the headlight first, observe its brightness, and judge whether the fault is caused by poor contact of the power line or battery power loss.

As an engineering vehicle, the dump trailer drives the hydraulic mechanism through the engine of the dump trailer, and then drives the lifting mechanism to complete the tilting action to achieve the purpose of unloading. When the unloading is completed, it will reset. So, what are the advantages of the rear dump trailer?The rear dump trailer has the characteristics of low center of gravity and difficult to overturn when lifting. The frame is made of 16 manganese beam plates, which greatly increases the bearing strength.

1. Early wear of the central part of the tire.The main reason is that the tire inflation volume is too large, which not only affects the shock absorption performance of the tire, but also causes excessive deformation of the tire.2. Both sides of the tire are worn too much.The main reason: insufficient inflation of the tire or long-term overload driving, so that the contact surface between the tire and the ground is large, causing the two sides of the tire to contact the ground and form early wear.3.

Changing the hydraulic oil looks like a simple job, but many friends of the driver of the rear-turning semi-trailer do not know how to change it correctly. They often mix the new and old hydraulic oil, which will greatly reduce the service life of the hydraulic system. So how to change the hydraulic oil of the rear tipper semi-trailer? Are there any precautions?The traditional method of replacing hydraulic oil for rear dump semi-trailer is nothing more than extracting the hydraulic oil from the hydraulic oil tank, replacing the hydraulic oil filter element, and then adding new hydraulic oil.
