Component parts according to industry standards GB / T14406 provisions 15 gantry crane, gantry crane is mainly composed of the following parts 1, 2 wheel cylinder, buffer 3, brake blocks 4, 5 wire rope, lifting hook 6, cab 7, 8 reducer casting pulley 9, casting reel 10, motor 11, electronic control device 3. Loosening new processing and assembly of parts, there is a deviation of the geometry and with the size of the initial period, due to shock and vibration alternating load, and the impact of heat, deformation and other factors, coupled with excessive wear and tear and other reasons, easy to make the original fastening parts loosening. 4, the occurrence of leakage due to loose parts, vibration and heat of 500t gantry machine, the machine's sealing surface and pipe fittings, etc., there will be leakage; part casting, processing and other defects in the assembly debugging difficult to find gantry crane, but because of vibration during operation, shock effect, this flaw is exposed, the performance of leakage (infiltration) oil (water). Therefore, prone to leakage run-in period. 5, operational errors and more as the understanding of the structure of the machine, the performance is not enough (especially the new operator), vulnerable to operational errors caused by malfunction, or even cause mechanical accident. 50t gantry crane, generous heavy (online consultation), camphor gantry provided by generous heavy machinery Co., Ltd., Henan Province. Heavy Machinery Co., Ltd., Henan Province, generous (www.hnqizhongshebei.com) (www.hnqizhongshebei.com) is Zhengzhou, engineering, construction cranes leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. In heavy generous leadership with the staff warmly welcome all inquiries negotiations to create a better future for heavy generous.
