Compared with traditional cranes, European-style overhead cranes have many functions. They are light in structure, easy to operate, and have various intelligent configurations and human-computer interaction functions.
The European-style overhead crane adopts a European-style special four-point hoisting mechanism that has a compact structure, lightweight, small size, and low wheel pressure, which can meet the requirements of different factory buildings for bearing capacity and height; it also has a lifting speed expansion function that can reach 1.5 times the rated speed. Low-load rapid lifting, speeding up the working cycle, and the automatic deviation correction function of large and small cars ensure that the wheels of large and small cars are always in the center of the track, ensuring positioning accuracy. The inching and micro-speed functions enable smooth docking with various spreaders, workpieces, and equipment to avoid collisions. The European-style crane adopts frequency conversion control, with stable operation and small impact, which can not only increase the service life of plant equipment, but also improve the comfort of workers’ working environments, and the safety aspect is also more guaranteed.
The large-scale mechanical equipment of bridge cranes has long and continuous working hours and high work intensity, which brings large power consumption to the factory. In today’s market, where energy conservation and environmental protection are advocated, how to reduce the energy consumption of bridge cranes has become a serious industry issue. The factory purchases European-style cranes to reduce power consumption from the following points.
The European-style crane is light in weight, and the steel structure accounts for most of the weight. Using the European-style mechanism can greatly reduce the weight and volume of the steel structure. To improve the form of the drum, a large-diameter drum can be used to increase the rope capacity and reduce the size and quality of the lifting trolley.
The European crane improves the control system. The speed control system is changed to a frequency conversion speed control system, which has high efficiency and a better energy-saving effect. Using new materials, such as replacing cast iron or steel with high-strength nylon, can not only prolong their lives but also reduce noise. Strengthen the daily maintenance of cranes, and don’t underestimate the daily maintenance. Daily maintenance can reduce structural damage and be a great help in energy savings.
European overhead cranes are popular with customers and have many features and advantages. The European-style crane has the advantages of stable operation, lightweight, a small pressure wheel, low height, energy savings, and consumption reduction, which greatly reduce the user’s construction cost of the crane’s operating workshop and the crane’s operating cost. Because the crane has the characteristics of being lightweight and having small pressure wheels, the space of the new workshop can be planned smaller and with more complete functions. Today, the editor mainly introduces the characteristics of stable operation and low noise, because many customers pay attention to the working environment, especially foreign customers, who have higher requirements, mainly because European cranes adopt frequency conversion technology.
The application of frequency conversion technology makes European crane products have better performance. The frequency conversion control of the hoisting mechanism solves common defects such as large lifting impact loads, unstable lifting brake, and falling brake hooks, etc., ensuring that the crane can start without impact and brake at zero speed; the frequency conversion of the operating mechanism can realize the non-impact start and brake of the crane operating mechanism, and the smooth synchronous acceleration and deceleration of multiple drives can realize the smooth operation of the crane, and at the same time, it can overcome the common operation steps caused by the crane. The shock and vibration of the crane and the plant structure are caused by the type of starting brake and the resulting deflection of the crane. The smooth operation of the mechanism will also improve the stress status of the relevant components, thereby greatly improving its working life.
