Pulley is lifting operations in a relatively accessory manufacturers, and for the type and material of the pulley and how much we understand it? The role of the pulley rope is used to change the direction of movement of effort reaches or balancing purposes. Axis movement is divided according to the pulley wheel lifting tackle alone, there are fixed pulley and pulley, lifting pulley fixed pulley mostly balanced and guide pulley. Divided by the manufacturing process 3T lifting tackle, has cast pulleys, forging and welding pulley sheaves made. Large pulley sheaves better welding, forging rarely uses pulleys, pulley hoist multi-use casting; steel pulley using ZG270-500; cast iron pulley using HT200; ductile iron pulley using QT400-18; Q235 steel welding pulley using solder. Lifting tackle strengths and routine maintenance of lifting tackle is an object of supporting small and medium sized equipment or products, lifting tackle is mainly used in mines, factories, oil, forestry, transportation lifting tackle price, infrastructure installation and marine terminals places. The following describes the lifting tackle your unique advantages: cast iron pulley material, excellent wear resistance, toughness reliable, hook block part of the national standard --JB / T4207.1-1999, safe and reliable. Pulley core using powder metallurgy oil sleeve, with flexible operation, strong, wear-resistant advantages and improve the life of the product. 1T lifting tackle, Sichuan lifting tackle, lifting Xinyu Xinyu provided by Crane Co. Qingyuan. Qingyuan Xinyu Crane Co. (xyqz0312.1688.com) strong, credible, Baoding in Hebei engineering, construction crane industry has accumulated a large number of loyal customers.
