Flexible and Accurate Single Girder Overhead Crane for 2.5Ton
Lifting Operations
| Feature | European-Style A5 Crane |
| Duty Classification | A5 (Heavy Duty/Intensive Use) – Designed for frequent,
high-intensity operations. |
| Structural Design | Lighter yet stronger due to optimized steel structures and
precision welding. |
| Hoisting Mechanism | High-performance hoist (e.g., modular design) with faster speeds
and longer service life. |
| End Carriages | Compact, low-headroom design with 42CrMo wheels for smoother
travel. |
| Control System | Advanced frequency control (VF drive) for precise, jerk-free
movement. |
| Maintenance | Reduced maintenance due to premium |
| Lifespan | Components; longer lifespan even in demanding conditions. |
| Cost | Higher initial investment but lower total cost of ownership (TCO). |
1. Lightweight structure, economical and practical:
It adopts a single main beam (usually I-beam or box beam)
structure. Compared with double-beam bridge cranes, it has lighter
deadweight and lower load-bearing requirements for factory building
structures.
The manufacturing cost is relatively low, and the installation and
transportation costs are also more advantageous. The overall
investment cost is small and the cost performance is high.
2. Simple operation and flexible operation:
It mainly relies on the electric hoist (usually a wire rope
electric hoist) suspended under the main beam for vertical lifting
operations.
The entire crane (trolley) can run longitudinally along the tracks
on both sides of the factory.
The electric hoist (trolley) can run horizontally along the track
on the lower flange of the main beam.
It is usually equipped with ground handle operation or wireless
remote control operation. The operator can flexibly follow and
control on the ground, with good vision, simple and intuitive
operation.
3. Wide coverage:
Through the longitudinal operation of the trolley and the lateral
operation of the trolley, it can be flexibly moved and accurately
positioned to the position where lifting is required in the entire
rectangular working area (span x length), effectively covering the
working area.
4. Moderate working level (A3-A5):
2.5 tons belongs to small and medium tonnage, and its design
working level is usually A3 (light) to A5 (medium). This means that
it is suitable for occasions with medium frequency of use and
medium load rate, such as:
Material handling (parts, semi-finished products, finished
products) within the workshop.
Equipment installation and maintenance.
Loading and unloading, stacking in the warehouse.
Feeding the assembly line.
Not suitable for extremely high strength, continuous heavy load and
other metallurgical scenes.
5. Relatively simple installation and maintenance:
Simple structure, relatively standardized components (especially
electric hoists), installation and commissioning are more
convenient than large double-beam cranes.
Daily maintenance (such as lubrication, inspection of wire ropes,
brakes, etc.) is also relatively convenient, and the maintenance
cost is relatively low.
