80 ton Double Girder Bridge Crane

Product Description

Electric double girder bridge crane with 80 tons large tonnage can be used in multiple scenarios

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. Super strong load-bearing capacity and structural rigidity

Main beam structure: adopts a high and thickened box-type double main beam, the steel plate thickness is significantly increased (usually ≥20mm), the section height is higher, and the bending and torsion resistance is extremely strong, ensuring that the main beam deflection is strictly controlled within the allowable range when fully loaded with 80 tons (usually ≤S/700～S/1000).

End beam design: heavy-duty box-type end beam, equipped with four-corner drive (8 wheels or more), larger wheel diameter (such as Φ900mm or more), evenly distributed load wheel pressure, to avoid local overload of the track.

2. Super high working level and durability

The design working level reaches A6/A7/A8 (heavy or extra heavy), suitable for 24-hour continuous operation, extreme working conditions with high cycle times (such as metallurgical continuous casting, large pressure vessel manufacturing).

The life of core components is doubled: gears (hardened tooth surface), wheels (alloy forged steel), reels (steel plate rolling), etc. are designed for fatigue life of ≥500,000 times, and heavy-duty spherical roller bearings are used for bearings.

3. Multiple safety guarantee systems

Triple redundancy of lifting and braking:

Main brake (high-speed shaft) + safety brake (low-speed shaft directly acts on the drum) + hydraulic electromagnetic backup brake.

Instantaneous response of emergency braking (≤0.2 seconds) to prevent heavy objects from falling in case of power failure or failure.

4. Upgraded overload protection:

High-precision electronic sensor (error ≤1%), dual-channel independent control, real-time display of load and linkage to cut off dangerous actions.

Wire rope anti-loosening monitoring: real-time monitoring of the tension balance of each branch to prevent single rope overload.

5. Strengthened lifting mechanism

Multi-rope winding system: adopt 4/6/8 rope scheme (such as 80 tons commonly used 8 ropes), evenly distribute the load through the balance beam, and reduce the single rope tension.

High-power dual motor drive: dual motors in parallel + dual reducer configuration (such as 2×75kW), equipped with an independent cooling system (forced air cooling or water cooling).

Heavy-duty hook set: alloy steel forged hook (grade ≥M), equipped with swivel bearing + anti-unhooking locking device.

6. Precision operation control

Full frequency conversion vector control: trolley, car, and hoist all use frequency conversion speed regulation to achieve millimeter-level precision positioning (within ±10mm).

Synchronous deviation correction technology: The four-corner drive of the trolley is equipped with encoder feedback, and the PLC automatically adjusts the motor speed to prevent rail gnawing and bridge frame skew.
