Synchronised sets of Bonfiglioli Transmission industrial gearboxes are being used on Sydney’s Harbour Bridge to drive two 60-tonne workmen’s gantries. The compact and versatile A series bevel helical gearboxes, basically used in manufacturing, mining, materials handling and primary processing applications, are used in sets of eight on each mobile platform to drive them along rails beneath the length of the 503m long main arch of the bridge.

The compact drives feature stainless steel brake components that have been fitted to the brake motors to ensure reliability of operation in marine environments. The drives are designed to ensure longevity of service on the Sydney Harbour Bridge.

The Sydney Harbour Bridge is a steel arch bridge with its top portion standing 134 metres above the harbour and has a total length of 2.3kms. This bridge carries eight road traffic lanes and two rail lines.

The Bonfiglioli A series drives feature FEA (Finite Element Analysis) procedures in the design and construction. These allow for lightweight construction, while maintaining strength and durability from case-hardened nickel chrome steel gears. Major features of the A series include high torque, high efficiency and low noise.

The A series covers an enormous range of small-to-medium-sized applications within industries such as construction and quarrying, cement, civil engineering, electricity generation, food processing, glass and bottle manufacture, general manufacture, bulk materials handling, metal production and water and sewage treatment. The A series drives can be used in conveyors, cranes, elevators, mixers, pumps, valves, winches and special purpose equipment.
