Observing the hot topics of audience attention from industry exhibitions

On May 12th, the 3rd Changsha International Construction Machinery Exhibition officially opened, and the global "Iron Man" gathered in Changsha at the Changsha International Convention and Exhibition Center. Now, the four-day exhibition has come to an end, from Changsha to the world. As the largest construction machinery exhibition in Asia this year, the global international construction machinery exhibition "hardcore" has emerged.
1、 The lively and bustling industry exhibitions
The 3rd Changsha International Construction Machinery Exhibition covers an area of 300000 square meters, with a total of 12 indoor pavilions, 7 outdoor exhibition areas, and 23 themed zones. Inside and outside the venue, various tower cranes, excavators, bulldozers, loaders, etc. are neatly arranged.
The participating companies include Caterpillar, the global leader in construction machinery: Sany Heavy Industry, Zoomlion Heavy Industry, China Railway Construction Heavy Industry, Shanhe Intelligent, Xingbang Intelligent, etc.
At the Changsha Engineering Machinery Industry Chain Supply and Demand Matchmaking Conference, 16 projects brought in a contract amount of 6.45 billion yuan, and the export of engineering machinery remanufacturing equipment signed over 1.06 billion yuan. The overseas market demand accelerated, and China's export market showed a strong recovery, rapidly driving the sales of domestic engineering machinery manufacturers in overseas markets. Taking the construction machinery Hunan Army as an example, it has established more than 20 research and development production bases, over 100 overseas offices and spare parts warehouses overseas, and its products are sold to more than 180 countries and regions worldwide. The export delivery value in 2022 increased by over 40% compared to the previous year.
It can be seen that in 2023, the overseas market will be larger than the domestic market, and exports have further requirements for product quality. To meet the requirements of foreign enterprise suppliers and export equipment in Germany, the United States, and other countries, quality management is not just ISO9000, but a full process quality management of CQA, DQA, MQA, and SQA.
What are the requirements for encoders in exports?
1. The multi turn encoder must be a mechanical gear, with reliable and secure data, and strong anti-interference ability
2. Requirements for anti vibration
3. Low temperature working environment requirement of minus 40 ℃
4. The requirement for high protection level ensures long-term use outdoors and in harsh environments
5. Maintenance free: Exporting overseas, the cost of running to the site in case of malfunctions is too high
6. EMC electromagnetic compatibility, which can effectively operate normally under alternating magnetic fields
At the exhibition, we saw the F series excavator from Shanhe Intelligent, which uses a professional customized brand engine and hydraulic components. It has a high-power engine, a large diameter main valve, a large displacement main pump, a high torque rotary and walking motor, and a more complete functional configuration; As far as we know, the positioning system of the excavator's rotary device uses CANopen communication for the rotary encoder, which can improve the positioning accuracy. At the same time, the encoder has strong resistance to vibration and impact during frequent construction, ensuring stable operation and greatly reducing maintenance costs.
Is the rotary encoder imported or domestically produced?
Originally an imported brand, but due to cost pressure and service response speed, the customer switched to a domestic brand encoder. This shows that the localization of construction machinery is a trend. Let's analyze the specific situation in detail. Why are imported brands repeatedly replaced by domestic brands?
1. Reduce costs (find domestic products)
After two years of epidemic, various enterprises have shifted from passive cost reduction to active cost reduction, using domestically produced products. Although imported products are good, they have long delivery cycles and difficult after-sales service. Compared to the financial pressure of hoarding a large amount of product spare parts for equipment, it is more practical to find a localized substitute product.
Not only Chinese people are looking for domestic products, but also foreigners such as Thailand, South Korea, Iran, Russia, etc. are looking for Chinese products. Cost reduction has become a global issue.
2. Reliability (high-quality development of enterprises and reliability of product quality)
The audience is eager to find domestic products to reduce costs, so what about the quality of domestic products?
Pay attention to these two points, and you won't fall into a trap.
1) Quality management of enterprises
2) Long term product consistency
3. Price
The cost-effectiveness that customers want: good quality, affordable price, reliability, and credibility.
The requirements of market customers for products will never change, and cost-effectiveness must be based on quality and reliability. Long term extensive after-sales service can also increase customer labor costs, which is also something that users need to consider.
4. Innovation
1) Product innovation
After a two-year hiatus, various companies showcased their newly developed products one after another, and there were also on-site competition activities to attract a large number of visitors to the exhibition booth. The release of new products has attracted an audience interested in cutting-edge technology, and every company's booth is crowded with people
2) Innovation in Quality Control
Compared to the influx of new products, the quality of the product is the key to solid powder. And how to achieve consistent quality, we have to talk about quality inspection methods. Innovation and improvement in hardware and software are secrets that enterprises cannot tell. Only when communicating face-to-face with booth sales can the story be revealed.
During the company's exhibition, the following products that caught the attention of the audience on our booth:
1. CANopen absolute value multi turn encoder
Support NMT node protection or heartbeat messages
Support multi master station redundancy
L has very strong EMC electromagnetic compatibility and EFT anti-interference pulse train
2. PROFINET multi turn absolute value encoder
Mature industrial Ethernet bus technology for digital factory construction
Convenient interconnection of devices from different manufacturers
Simple wiring, easy debugging, convenient diagnosis, highly integrated, and strong network anti-interference ability
3.4-20mA multi turn encoder
Dual signal output, can directly replace potentiometer, RS485 digital remote transmission
One click intelligent setting function, which can match with mechanical zero position with one click and adjust the setting position using software
Can meet high requirements for accuracy, temperature drift, and disturbance resistance at high temperatures
4. Pull rope displacement sensor
Encoder compatible with any communication signal
The installation method is simple and diverse, and can be flexibly applied to various locations
Long working life, high protection level, accurate linear accuracy
Finally, let's have an advertisement
