HD type European single girder overhead crane adopts the most advanced international design concept and technology according to GB / T 3811-2008 “crane design code” Chinese national standards and DIN (Germany), FEM (Europe), ISO (International) standards, usually used with Nd type European electric hoist, widely used in mechanical processing, metallurgy, petroleum and petrochemical, power, paper making, construction materials and other industries workshops and warehouses for material handling, especially for materials handling and parts precision assembly and other places.
The lifting capacity of HD single beam crane is generally 1-20 tons, span is 7.5-31.5 meters, working level is a3-a6, working environment temperature is – 20 ℃ ~ + 40 ℃, relative humidity of air is not more than 85% (environment temperature is + 25 ℃), and there is no environment condition of inflammable, explosive and corrosive medium. The power supply of crane is three-phase AC, rated frequency is 50Hz or 60Hz, rated voltage is 220V ~ 660V. The upper and lower limit of allowable voltage fluctuation on motor and electrical control equipment is ± 10%, and the internal voltage loss of crane is not more than 3%.
European single girder crane is mainly composed of European electric hoist, bridge (main beam, end beam), crane operation mechanism and electrical control operation system. It has the characteristics of light weight, small structure, low energy consumption, small wheel pressure, maintenance free components, safe and reliable, beautiful shape, and low headroom, which can reduce the building height of the plant and greatly save the building cost of the plant.
