The position of the delivery items contained in the warehouse-type semi-trailer is a semi-trailer designed with a fence structure. The main use of most vehicles is to transport agricultural and sideline products such as fruits, vegetables, and some of the daily necessities we use in our lives, as well as other types of light-bulk goods. It is the semi-trailer Gatton tool that we often see in daily life. It is also an essential transportation vehicle in express companies and check-in stations. However, in terms of power engineering and communication engineering, the warehouse-type semi-trailer truck can also play a good role, because some of the small equipment used in the project are used warehouse gate semi-hung Transporter to transport.
1. The design and structure of the fences and models of warehouse-type semi-trailer trucks are combined with the use of the user's category of transport goods to carry out a more reasonable design. It can be satisfied that the weight of the cabin can be reduced under the condition that the load is carried out. The structure of the vehicle is also relatively simple and applicable. It is more convenient when disassembling and can reduce the investment cost for the owner.
2. The structure of the space frame welded by the longitudinal girder used for the slat -type semi-trailer and the entire cross-beam group. Such a structure can well balance the rigidity, toughness, strength, and ability of the frame of the silo-type semi-trailer truck to be carried by the vehicle, and it will not cause permanent deformation.
3. The frame of part of the gated-type semi-trailer truck is of a beam-type structure, and the stringer structure uses a goose-neck type or a flat type. The height of the web is between 400 and 500, and the welding method used for the stringer is the automatic submerged arc welding method. The frame of the vehicle is used for shot blasting, and the beam is inserted into the stringer and welded into a whole.
4. The suspension systems used in the warehouse-type semi-trailer are all new, and they have better impact resistance and high strength. The shaft load of each axis is relatively balanced, and the angle of its system pull rod is also relatively reasonable. In the process of driving, the warehouse-type semi-trailer encounters bumpy road sections and can reduce the friction between the wheel and the ground. The slip distance can well reduce the degree of wear of the vehicle tires. And can adjust the lever at the same time, adjust the wheelbase, can be a good way to avoid the occurrence of uneven wear and tear wheel.
Engineering Plastics
Engineering plastics are a bunch of plastics that are used most ordinarily in industries because of their enhanced mechanical and thermal properties. They are used mainly in situ of thermoplastic materials instead of thermosetting ones because of the fact that they will be remolded into the specific shape and size whether or not after cooling and settling down. In accordance, to the suitable convention and standards, the definition of engineering plastics (McQuiston, 1980) are: (1) the family of nylon; (2) polycarbonate; (3) polyphenylene oxide; (4) acetal; (5) engineering grade of ABS; (6) polysulphone; and (7) polyphenylene sulphide. Engineering plastics become the fabric of choice for various applications because of their good mechanical, chemical properties, strength, rigidity, self-lubrication, and fire safety. Certain groups of engineering plastics which include polycarbonates and polyamides are useful in industries due to their high resistance to impact and abrasion respectively.
