European crane is a new type of mid-high-end gantry crane based on the European lightweight and modular design concept and advanced manufacturing technology, combined with the use characteristics of China and the new requirements for gantry crane. European crane adopts a unique design concept, with small size, light weight, small wheel pressure, low noise and other characteristics. It is mainly composed of truss, lifting trolley and operation mechanism. Through the movement of large and small trolley, materials and objects can be transported in three-dimensionalspace.
Compared with traditional QD electric double girder crane, European electric double girder bridge crane is an intelligent crane with more reasonable structure, better assembly and performance. After lightweight design, the European electric double girder bridge crane has the following characteristics: 1. Height: The total height of the crane is 20%-25%, which is lower than that of the traditional crane; 2.Self-weight: Self-weight isreducedby20%-30%; 3.Structure:Thecostofplantconstructioncanbereducedduetothelightweight structure; 4.Size: Thelimit sizeissmall, soastoincreasetheoperationareaofthecrane;
5.Wheelpressure:Themaximum wheelpressureisreducedby15%-20%; The lifting weight of European electric double girder bridge crane is (Gn=5-500t), the span is 10.5-35m, the working level is A3, A5, A6, and the temperature of working environment is below +40℃. European crane adopts hardened reducer, high strength steel wire rope, three-in-one transmission, equipped with sound-light overload alarm, anti-hook punching self-stop secondary protector, circuit self-check protector, over-current missing protector and intelligent self-stop limit and other all-round protection. Electrical appliances adopt module debugging control or frequency convertercontroltoensuretheaccuratepositioningofcraneduringtheliftingprocess. The selection method of European electric double girder bridge crane: determine the industries to use it and the working level of the crane, limit dimensions of installation and use, power supply side, environmental temperature, operation speed, operation mode, etc. The unspecified items needtobelistedindetail inthetechnicalrequirements.
