Line hanging and other manufacturing needs respected diversification in recent years, the line hoists and other lifting equipment showing the development trend of steady growth, with China's sustained economic development, the crane market has also been a rapid growth line hanging structure, according to Chinese mine Machinery Industry Association statistics show that: in 2010 China's mining hoisting machinery market sales reached four hundred billion yuan, while in 2011 broke the five hundred billion yuan of sales. Line hanging at this time, China has become the world's largest mining machinery market. Experts predict that in 2015 the price of line hanging, China's mining machinery market sales will exceed nine hundred billion yuan. Economic and technological level of continuous development in the crane manufacturing industry, the single product strategy and marketing strategy has been unable to meet contemporary business development demand, product diversification, the type of diversification, diversification of services and other diversified business strategy is the crane manufacturing enterprise development focus. Line hanging bearing rust treatment if the bearing line hanging on a rusty can apply anti-rust oil using a method commonly used immersion, brushing, spraying. Prior to apply anti-rust oil to the bearing surface must be clean single girder crane line, depending on the nature of rust-proof surface and the prevailing environment, choose the appropriate method should be clean. Generally the most commonly used method of mechanical cleaning, chemical treatment and solvent cleaning method cleaning method. The surface to be cleaned in dry air or dry with a clean gauze. When bearing immersion method, a number of small items should be soaked in anti-rust oil, allowed to adhere to the surface of the layer of rust oil method, whereby the film thickness can be controlled by anti-rust oil temperature or viscosity to achieve.
