4Ton Electris Single girder overhead crane applies to Construction Site Lifter,warehouse
| 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. Low requirements for plant space:
The single-beam structure makes the overall height of the crane (H size) relatively small, effectively utilizing the plant space, especially suitable for workshops with limited clearance height.
The track is usually installed on the bracket of the plant frame or column, and does not occupy the ground space.
2. Driving mode:
Trolley operation: Usually driven at both ends (i.e., each driving wheel on both sides has a set of motor + reducer + brake) or centralized drive (a set of drive devices drives the wheels on both sides through a long drive shaft).
Trolley operation (i.e., electric hoist operation): driven by the trolley operation motor of the electric hoist.
3.Simple operation and flexible operation:
Mainly rely 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 plant.
The electric hoist (trolley) can run horizontally along the track on the lower flange of the main beam.
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.
