1. Lightweight structure and light weight:
This is one of the core features of European cranes. It adopts an optimized box beam or truss beam structure (usually the main beam is a skewed or semi-skewed box beam, and the end beam is a three-beam structure), which minimizes the weight of the crane itself while ensuring strength and rigidity.
Advantages: It reduces the pressure requirements on the load-bearing structure of the plant (corbels, columns), which can save the cost of plant construction; it is especially beneficial for the renovation of old plants or limited space; it reduces the inertia during operation and is more energy-efficient.
2. Compact size and high space utilization:
European design pursues extreme space utilization. It is reflected in:
High limit position of the hook: The hook can run very close to the top of the plant, which effectively improves the vertical utilization of the internal space of the plant.
Small end beam size: The narrow width of the end beam reduces the "dead zone" space of the crane in the track direction.
Compact trolley frame: The trolley structure is exquisitely designed and the wheel pressure distribution is reasonable, making the trolley width relatively small.
Advantages: Under the same plant span, it can provide a larger effective lifting height and working coverage; it is particularly suitable for occasions with compact space or the need to maximize the use of existing space.
3. Smooth operation and precise positioning:
Thanks to the precise manufacturing process and advanced control system:
Drive system: The "three-in-one" drive mechanism (motor, brake, and reducer are integrated into one) is generally adopted, with compact structure, high transmission efficiency, and good synchronization.
Variable frequency speed regulation: The hoisting, trolley, and trolley operating mechanisms are usually equipped with variable frequency stepless speed regulation control as standard. It can achieve smooth adjustment of start, stop, and running speed, effectively suppress load swing, and achieve millimeter-level precise positioning.
Rigid design: The main beam and end beam are reliably connected, with good overall rigidity and small running shaking.
Advantages: Greatly improve loading and unloading efficiency and operation safety; reduce the impact on hoisted objects; meet the requirements of precision assembly, high-precision positioning, etc.
4. Superior performance and high working level:
European cranes are usually designed and manufactured according to international standards (such as FEM, DIN), with high working levels (such as A5, A6 or even higher). This means:
The selection of key components such as motors, electrical components, and steel structures leaves sufficient safety margins.
It can adapt to more frequent starts and stops, longer daily working hours, and higher load rates.
