Product Description
Double girder bridge crane with easy operation and 100ton 22m Workshop use
| Feature | European-Style A5 Crane |
| Duty Classification | A5 (Heavy Duty/Intensive Use) |
| 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 (VFD) for precise |
| 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. Beam structure
Double-layer box-type main beam: 30~40mm thick high-strength steel plate (Q345B or above) is welded into a closed box, and longitudinal stiffening ribs + transverse partitions are added inside, with anti-deflection capacity of ≤S/1200 (full-load deformation in the middle of the span <10cm/120m span).
Pre-camber: The prefabricated camber of the main beam is ≥1.4S/1000 (such as 168mm pre-camber for a span of 120m), offsetting the risk of permanent deformation.
2. End beam and walking mechanism
Eight-wheel or sixteen-wheel load-bearing: The end beam uses four sets of balancing trolleys (2~4 wheels per set), and the wheel pressure is evenly distributed to the track, with a maximum single wheel pressure of ≤45 tons.
Large-diameter wheels: Alloy forged steel wheel diameter ≥Φ1000mm, tread quenching hardness HB≥320.
Four-corner full drive: 16-wheel model is equipped with 8 independent three-in-one drive units (motor + reducer + brake), with synchronization accuracy error <0.1%.
3. Structural health monitoring
Fiber optic strain sensors are arranged at key points of the main beam to monitor stress changes in real time (automatic shutdown if exceeding the limit).
Track settlement monitoring system (accuracy ±1mm).
4. Electrical safety
Three-channel PLC control system: two sets of main control + 1 set of hot backup, fault switching time <50ms.
Voltage fluctuation tolerance range: ±15% (equipped with a stabilized power supply).
5. Operation protection
Laser three-dimensional anti-collision system: detection range 30m, automatic generation of virtual electronic fence.
End hydraulic buffer + polyurethane energy absorption block (absorption energy ≥50kJ).
