Tower crane drive inverter development
by Cindy Liu marketing director China Tower crane is movable arm is installed on the top of the rotation of the tall tower crane, the operation space is large, it is mainly used for building construction materials in the installation of vertical and horizontal transportation and construction.The main mechanism of tower crane hoisting mechanism, luffing mechanism, car traction mechanism, slewing mechanism, and cart go line.
Since the 1980 s, the tower crane industry get fast development of our country, in recent years, the tower crane sales still rising.But can not be ignored is the domestic models are centered, market competition pressure, is not conducive to the development of the industry, the need for a series of reforms.At the same time, the product quality is uneven, market access restrictions are not strictly.As GB/T5031-2008 tower crane standard editor Luo Wenlong director of that, he said: "in the new standard, enlarge the using range of the standard, in line with international standards. It also raised some agencies require the technical data requirements of the device, safety, etc. This will to a certain extent for domestic products in the international competition aggravate chip."
He also pointed out that our country most of the tower crane is small and medium-sized tower crane, because most of the small and medium-sized tower crane's overall cost is not high, if use the automation products such as frequency converter, PLC, will significantly increase the capital cost, so the current tower crane industry automation products application ratio is very low.The whole tower crane market, inverter application proportion about 11.2%, speed control mode with double speed/multispeed motor or series resistance speed control.The inverter in the tower crane in the enterprise has been widely recognized, large tower crane basically the application of frequency converter, medium speed also have quite a number of using frequency converter, but also small tower crane application level is very low, most use double speed/multispeed motor or series resistance speed control mode.ROM the director stressed that the tower will further promote the development trend of large-scale application of inverter and other automation products, at the same time small tower crane market development has huge potential for inverter great development space.
