Yanshan Xian Xin Wantong Machinery Co., Ltd. specializes in producing steel shield. We equipped with poly-resin or brass slider speed 10m / min below. Equipped with roller medium speed 30m / min below. Driver board, need to use between scraping plates and sucking board buffer system, aimed at reducing the impact, noise and friction. Number of section steel shield its proportions, weight and operating characteristics are important. Each block should be as long as possible, thus reducing the number of sections, in general, the maximum tensile and minimum compression ratio should be 3: (up to 10: 1) between 1: 1 and 5. When the width of the larger must fold increase lateral stability. Roof type and folding can be done, tilting of the liquid and debris can flow away automatically. Equipment advantages: 1, the shroud can move bursts with every piece, completely different from the general shield machine pull piece after piece telescopic steel shield package shipping package safety, noise is extremely low. 2, the shell means the use can increase service life. 3, steel shield device can shield the moving speed rises 120m / min and withstand higher G value (2G). 4, steel shield means moving parallel with the shroud (avoiding the disadvantages of the general shear-type shield is still meandering). 5, can be more stable at high speed without vibration. Price reasonable standard structure (1) is suitable for most applications industry-speed steel shield retractable door guard values, width up to 900mm, width is larger must hemming steel shield, improve lateral stability. This roof type (3) and folding (4) can be done. Also tilting (2) may well be the liquid and debris flow away. Number of sections of steel retractable shield on its scale, weight and operating characteristics are important. Each block should be as long as possible, thus reducing the number of sections, and reduce costs. Normally the maximum tensile minimum compression ratio should be 3: 1 and 5: 1 between the (up to 10: 1). Machine telescopic steel shield package shipping package safe, Xin Wantong machinery, steel shield provided by the Yanshan Xian Xin Wantong Machinery Co., Ltd Yanshan Xian Xin Wantong Machinery Co., Ltd. (www.ysxwtjx.com) is an industry leader in Cangzhou, Hebei, machine tool accessories, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
