China's lifting machinery industry automation products market situation analysis
From the current industry scale, growth rate, policy benefits and other directions, China's lifting machinery industry market is constantly developing, crane technology level is also constantly advancing, more and more lifting machinery manufacturers and lifting machinery users are gradually recognized the advantages of the application of automation products, lifting machinery automation market demand trends are more and more obvious, which can be broadly divided into the following three areas: First, the extension of Product line, according to the characteristics of the Chinese market, vigorously develop more flexible, efficient, easy to operate automation products; Second, strengthen the domestic application of technical personnel automation products related training; Third, reasonable according to the characteristics of the lifting machinery industry, cost control, reasonable pricing.
This review by focusing on lifting machinery automation products in the industry with a representative PLC and inverter two types of products in the specific application, to specifically analyze the market situation of automation products in the crane industry.
PLC
In the lifting machinery industry, PLC applications are more common, in addition to tower cranes, simple industrial cranes, the use of relay control products, other cranes all use PLC control, especially large tonnage lifting machinery. Depending on the product and the specific tonnage, general lifting equipment needs to be equipped with at least 1-4 PLC. cranes using PLC covers large, medium and small IO sections, large port machine control points up to thousands, usually using large PLC and fieldbus, Siemens s7-300/400 use the most; ordinary cranes mainly use small PLC control, the main brands include Mitsubishi's FX, Siemens' S7-200, Omron's CS, etc.
According to relevant research data, MIR predicts that in 2011 the lifting industry PLC market will reach 105 million yuan. In addition, in China's high emphasis on safety, high efficiency and energy saving background, lifting machinery industry PLC products will also be developed in the direction of high performance, high capacity, which will certainly simplify the control circuit, and thus reduce the failure rate. At the same time, as the technology continues to mature, the price of PLC will continue to decline, which will accelerate the popularity of PLC in the lifting machinery industry more quickly. In addition, PLC's networking and communication capabilities to be strengthened, which will enable PLC and personal computers or with other intelligent control equipment to exchange digital information between the formation of a unified whole, to achieve decentralized control and centralized management.
Inverter
Lifting machinery is one of the main industries where inverters are used, mainly in the large car, trolley, lifting, slewing and tilting, and the market for inverters in the lifting industry is expected to reach 1.2 billion yuan in 2011. Lifting machinery industry mainly needs vector frequency conversion, torque control and other functions of the products with high requirements; from the power point of view, mainly large products. Due to the industry's high functional quality requirements of the inverter, strong purchasing power, the current industry enterprises rarely use domestic brands of inverters, more foreign brands, which mainly include: Siemens, ABB, Yaskawa and Fuji.
More force in the crane industry has become the top priority of inverter manufacturers industry-oriented, basically the market position achieved in the field of cranes, determines its overall inverter market ranking. Yaskawa relying on its excellent price/performance ratio, the crane market leader, but the first half of 2011 earthquake in Japan, making the second quarter supply is very tight, the delivery period is very long, while Yaskawa use the channel sales approach, the lack of direct control of the market. The next largest market share is ABB and Siemens, ABB and Siemens in the crane industry has become the first choice for high-end models, such as shore-side container cranes, floating cranes, nuclear power cranes, etc.. However, as Zhenhua Port Machinery is an important user of these two brands, the decline in the performance of Zhenhua has also caused some impact on the two brands. Fuji 2011 market share of less than 10%, the performance is mainly due to orders in Zhenhua Port Machinery, but also affected by the decline in the business of Zhenhua Port Machinery. Other well-known inverter manufacturers Mitsubishi, Schneider, etc. in the field of cranes, there are signs of development in recent years. Mitsubishi has a good reputation in the field of industrial industry, Schneider with its low-voltage electrical and comprehensive power, the formation of a crane team in 2009 to provide integrated automation solutions, in the field of industrial industry has reaped some projects.
