SPECIALIST SOLUTIONS FOR BRIDGE CONSTRUCTION

Marr’s craneage solutions for suspension and cable-stayed bridge tower erection accelerate construction by providing high-volume and high-capacity cranes that:

Reduce the number of critical path lifts required
Maximise component sizes
Utilise high-speed winches to lift faster.

Early engagement with us opens the possibility to incorporate crane capability in tower component design providing the opportunity to:

Lift larger pre-cast and structural steel components
Lift heavier pre-assembles and modules
Maximise offsite fabrication and pre-assembly.

UNIQUE FEATURES & BENEFITS

Low carbon offsite fabrication and pre-assembly possible
Decrease in temporary works on bridge tower and critical path activities
Reduction in the need for working at height
Increased availability in high wind speeds – our cranes are rated to operate in wind conditions of up to 20m/second resulting in increased utilisation and availability
Small base footprint – offering improved logistics on tower bases to improve efficiencies
Larger crane tower design permits greater free-standing height.
