As an essential component of the scale - the weighing platform, the materials and performance selected will directly affect the lifespan of the weighing platform. The electronic weighing platform.

What kind of scale body is suitable for personal use? This issue has become one of the key factors in choosing a weighbridge. The various weighing platforms produced by each manufacturer are similar and slightly different. Below is an analysis of the structural classification and performance of the weighbridge body:

The weighbridge can be divided into U-shaped steel weighbridge, channel steel weighbridge, I-shaped steel weighbridge, and reinforced concrete weighbridge (commonly known as cement weighbridge) according to its structure.

1. Comparison between channel steel and U-shaped steel.

Why choose to make a U-shaped steel weighbridge instead of a channel steel weighbridge? Here are some tips for you:

①Let's first talk about the channel steel scale body. It is mainly composed of channel steel as the main beam, connected one by one by transverse partitions, and then sealed with a sealing plate at the bottom.

The U-shaped steel scale body is supported by U-shaped steel at the bottom based on the principle of bridges, without sealing plates or formwork partitions.

Compared to the same model of scale body, the weight of the channel steel scale is greater than that of the U-shaped steel scale body. The cost is higher than the U-shaped steel scale body. The channel steel scale body has a sealing plate for tension, while U-shaped steel does not.

②From a welding perspective, the U-shaped steel scale is fully welded, while the channel steel scale is spot welded. So, the industry believes that U-shaped steel is better than channel steel.

At present, the manufacturers of weighbridges in the market mainly use U-shaped steel and channel steel, among which U-shaped steel structures have become mainstream in the market. In the United States, Germany, China, and even around the world, weighbridge manufacturers use U-shaped steel structures and U-shaped steel weighbridges.

③Channel steel belongs to the third generation weighing products. The bottom of the channel steel has two supporting beams, and the middle is empty, so the supporting performance is worse. Simply put, the steel structure ratio is not very reasonable, and the channel steel scale is equivalent to using steel plates to piece together. But in terms of the weight of the scale body, the same tonnage of channel steel is heavier than U-shaped steel, which is the truth.

 

U-shaped steel is the fourth generation product of industrial scales, and the equipment required for making U-shaped steel scales is a bending machine. Adopting a 600T large double machine continuous bending machine, the shearing machine has high positioning accuracy and fast speed, and the equipment is the most advanced in the same industry in the province. If you buy this bending machine on the market, it will cost over 600000 yuan, so the price of U-shaped steel scales is higher than that of channel steel. The steel structure is relatively reasonable, with good stiffness, strength, and strong resistance to lateral forces. Therefore, the scale body is anti winding and has a long service life. The bottom of the U-shaped steel is designed using a bridge structure.。

The U-shaped steel weighing platform adopts 5-7 U-shaped main beams (designed according to tonnage and table size) to ensure the overall rigidity of the weighing platform. The internal cavity of the weighing platform is fully sealed and not easy to rust. After shot blasting and rust removal treatment, the steel plate is coated with epoxy zinc rich primer and acrylic acid marine paint, with a thick oil film and a thickness of 100 microns, and has stronger resistance to pressure, acid, alkali, and corrosion.

2.I-beam, also known as steel beam, is a long strip of steel with an I-shaped cross-section. Its specifications are expressed in millionths of waist height (h), leg width (b), and waist thickness (d). For example, "I 160 * 88 * 6" represents an I-beam with a waist height of 160 millimeters, a leg width of 88 millimeters, and a waist thickness of 6 millimeters. The specifications of I-beams can also be represented by models, which represent the centimeters of waist height, such as I-16 #. For I-beams with the same waist height, if there are several different leg widths and waist thicknesses, a b c should be added to the right of the model to distinguish them, such as 32a # 32b # 32c #, etc. I-beam is divided into ordinary I-beam and light I-beam, and the specifications of hot-rolled ordinary I-beam are 10-63 #. The specifications of hot-rolled ordinary I-beam supplied through agreement between the supply and demand parties are 12-55 #. I-beam is widely used in various building structures, bridges, vehicles, brackets, machinery, etc.

Due to the relatively low use of I-beam in the automotive weighing equipment industry, domestic and foreign peers mainly use U-shaped steel and channel steel. I will not analyze it in detail here.

3.The biggest difference between reinforced concrete weighbridge (commonly known as cement weighbridge) and fully electronic weighbridge, digital weighbridge, and analog weighbridge lies in the difference in the structure of the scale body. The former is a reinforced concrete structure, while the latter is an all steel structure. The instruments, junction boxes, and printer sensors used in these weighbridges (commonly known as car weighbridges) are generally the same, with similar working principles and lightning protection facilities. The construction of the foundation of the weighbridge is the same, and there is no essential difference in functionality. However, the production cycle of cement scales is much longer than that of full steel structures, so if cement scales are to be used as weighbridges, it is best to negotiate with the manufacturer early to avoid delaying the time when the weighbridge is put into use.

Advantages of cement scale: It fundamentally solves the problems of scale body corrosion, reduced accuracy, and shortened service life caused by rain, sun, acid, alkali corrosion, and thermal expansion and contraction of the structure during the use of all steel structure weighbridge. It has corrosion resistance, structural stability, self weight, accurate positioning, no deformation, and no maintenance.

Suitable for industries such as public weighing stations, chemical enterprises, ports and docks, and the refrigeration industry that have high requirements for anti-corrosion functions.
