European crane
European crane has light weight, small structure and low energy consumption. A trolley and lifting mechanism are set on the bridge. The trolley can run back and forth, and the cart can run, so as to realize the transportation of materials and objects in three-dimensional space. European crane adopts a unique design concept, which has the characteristics of small size, light weight and small wheel pressure. Compared with traditional cranes, the limit distance from the hook to the wall is small, and the clearance height is low. The Keli crane can work closer to the front, and the lifting height is higher, which actually increases the effective working space of the existing plant. Because the crane has the characteristics of light weight and small wheel pressure, the space of the new plant can be designed smaller and more complete. A small plant means that a considerable amount of money can be saved in the initial construction investment and long-term heating, air conditioning and other maintenance costs.
Product concept
European crane is a kind of medium and high-end gantry crane. The concept of European crane is not included in the professional terminology. It is the requirement of domestic crane users for gantry cranes according to the use characteristics of China, which summarizes the reliability, versatility and low price of domestic cranes (derived from the Soviet design and manufacturing Technology), combined with the advanced European crane technology, compact structure, light weight, energy saving, low noise and other characteristics, It is a clear market demand and a new definition of medium and high-end gantry cranes.
The concept of European crane was formed in the industry in recent years to distinguish it from the so-called domestic, Soviet (Soviet) and traditional cranes in the past. It mainly includes: bridge crane, gantry crane, cantilever crane, flexible beam crane, explosion-proof crane and other industrial cranes.
European crane is based on the European lightweight and modular design concept and advanced production and manufacturing technology, which makes the whole crane compact in structure, stable in operation, light in weight, low in height, energy saving and consumption reduction, greatly reduces the construction cost of the crane operation plant and the crane operation cost, and improves the overall quality and operation performance of the crane. European crane will become the mainstream of crane development trend and market demand.
Structural features
Main beam
1. The main beam adopts the square box Ankang H-shaped steel structure design, which is similar to the traditional simple crane at the beginning, and its self weight is heavier;
2. NDT shall be carried out for main welds;
3. The steel plate material is domestic general steel (Q235B);
4. The vertical winding is in accordance with Chinese national standards;
5. Like traditional cranes in China, all steel plates are shot blasted to achieve Sa2.5 standardization;
6. Before welding, carefully check and clean the steel plate, which is usually welded by automatic welding machine (MIG or semi-automatic welding);
End beam part
1. The end beam is formed by welding rectangular steel pipe or steel plate. The formed end beam is positioned and processed at one time in the CNC machine tool to reach the allowable deviation range and ensure the national dimensional accuracy and fit tolerance;
2. Each end beam is equipped with wheels with double rims, buffers and anti derailment protection devices;
3. The double beam crane is equipped with a maintenance platform (maintenance walkway) on the driving side of the crane along the main beam direction;
4. The main beam and end beam are connected by high-strength bolts to ensure the accuracy and stable operation of the whole machine;
Product advantages
European bridge and gantry crane products have light weight, small net height of equipment, large working range, high-quality components, strict manufacturing quality control, and high cost performance products with safety, reliability, excellent performance and less maintenance. Compared with traditional industrial cranes, the main advantages of European cranes can be divided into the following aspects:
1. Reduce customer investment, make full use of plant space and improve production efficiency
European crane products have the characteristics of light weight, small wheel pressure, low equipment height, compact structure and small space occupation. International advanced technology is adopted. Reasonable structures are adopted from trolley, end beam to main beam, and its self weight is much lighter than that of traditional cranes. Therefore, under the condition of meeting the same needs, the height of the plant can be reduced, the cross-section size of the rail bearing beam can be reduced, the bearing capacity of the bracket and pile foundation can be reduced, and the requirements for the track and power supply sliding line can be reduced, so that the comprehensive investment of users in the plant and lifting equipment can be reduced.
Taking EW series of European cranes as an example, compared with domestic traditional lifting trolleys, EW European crane trolley weight is reduced by more than 30%, and the net height of equipment is significantly reduced, which can effectively reduce the comprehensive construction cost of user workshops, and has obvious advantages of energy conservation and consumption reduction.
