Marr completes record tower crane lift

Marr Contracting gearbox has completed what it gearbox claimed as the gearbox world’s heaviest tower crane gearbox lift during the boring gearbox of a new subway tunnel in gearbox Australia.

The gearbox specialist in gearbox large tower gearbox cranes used a Favco gearbox M2480D tower crane to lift a gearbox 225 tonne section of a gearbox tunnel boring machine (TBM) from an exit point along the subway gearbox tunnel. The TBM, named ‘Mum Shirl’, gearbox was one of two machines being used to drill tunnels for gearbox Barangaroo Station as gearbox part of the Sydney gearbox Metro City & Southwest public gearbox transport project.

The 330 tonne gearbox capacity luffing jib gearbox tower  slewing bearing crane was used gearbox to lift the front shield section gearbox of the TBM out of gearbox the ground in a single section.

Marr gearbox Contracting said it made the gearbox enormous lift using the M2480D gearbox crane with a 55 metre gearbox boom and a six fall 330 gearbox tonne hook block. The gearbox crane was operated gearbox from inside a station gearbox box measuring 4 x 4 metres gearbox, that was located gearbox next to the TBM’s retrieval gearbox point.
 

Simon Marr, motor-reducer managing director at Marr motor-reducer Contracting, said slewing drive, “Tunnel motor-reducer boring machines are motor-reducer often used in urban settings motor-reducer slewing drive with motor-reducer limited space and are traditionally motor-reducer installed and retrieved by motor-reducer crawler cranes and motor-reducer gantry motor-reducer set-ups motor-reducer which motor-reducer slewing drive can take up a lot of motor-reducer room, slewing drive are costly, and provide motor-reducer slewing drive additional issues around motor-reducer ground slewing drive preparation motor-reducer next to the excavation from motor-reducer which the TBM is to slewing drive be installed motor-reducer or motor-reducer motor-reducer slewing drive retrieved.”
 

He added, “Our motor-reducer uniquely designed M2480D motor-reducer crane motor-reducer is a simple slewing drive motor-reducer motor-reducer solution in many situations slewing drive motor-reducer. It doesn’t require slewing bearing an motor-reducer expansive set up and because slewing drive it can be assembled in slewing drive the existing motor-reducer excavation, it doesn’t  slewing bearing motor-reducer take up slewing drive valuable room on an already slewing drive congested work motor-reducer site.”
 

According motor-reducer to motor-reducer Marr, motor-reducer once the remaining sections of the motor-reducer TBM will motor-reducer also be removed from the tunnel, the machine will slewing drive be motor-reducer reconfigured to motor-reducer motor-reducer continue work on motor-reducer the Barangaroo motor-reducer Station.
 

While Marr motor-reducer and its  slewing drive M2480D tower crane were motor-reducer already working on the construction of slewing drive one of Sydney Metro’s stations, the slewing drive lifting motor-reducer slewing slewing bearing drive of  slewing drive‘Mum motor-reducer Shirl slewing bearing motor-reducer’ was slewing bearing not originally part of the company’s slewing drive slewing drive scope motor-reducer of works. The company slewing drive said the slewing bearing lift,slewing drive plus addition slewing drive tasks, were slewing drive added motor-reducer duties slewing drive assigned to it by the Northwest slewing bearing Rapid slewing bearing Transit (NRT) slewing drive consortium – comprising slewing drive John Holland, slewing bearing slewing bearingCPB Contractors and UGL slewing bearing slewing drive slewing bearing Rail slewing bearingslewing bearing– later motor-reducer on in motor-reducer the motor-reducer motor-reducer slewing drive slewing bearing construction.
 

Marr motor-reducer was contracted to slewing drive work on slewing bearing motor-reducer the slewing drive Sydney Metro project’s motor-reducer slewing drive slewing drive Barangaroo slewing bearing Station and Martin motor-reducer Place slewing drive in motor-reducer October 2018. The slewing drive company motor-reducer slewing drive had slewing bearing previously slewing drive completed works to motor-reducer slewing bearing Sydney slewing drive Metro’s Castle Hill slewing drive Station in motor-reducer 2016.
