Crane and lifting awards for excellence

20 March 2008

Mammoet's MSG-80 was used to lift a 2,016 tonne reactor for a Chinese state company. It was the first of two reactors that, together with a 1,250 tonne tower, will form the centre of a coal power station in Inner Mongolia.

The Mammoet team started building the MSG at the end of May 2006 and three weeks later the crane was ready and tested.

The equipment had to be transported some 1,250 km from the nearest s ea p ort, which p roved time-consuming.

In the meantime, a second team jacked up and weighed the reactor, before placing rollers and SPMTs underneath it in preparation for its 3 km journey from the factory to the job site.

I here, work was carried out to prepare the tailing frame which was placed on skid tracks to get the tank upright.

Mammoet also designed a type of cap, called a top lug, for the project, connected to both reactors using 24 x M90 bolts with a moment of 27,000 Nm.

It took 12 hours to lift the 103-R-201 reactor up on to its foundations and a few days later the team had completed the task.

At the time of writing the work was to be repeated in a few weeks on thesecond reactor.

BMS lifted a 203 tonne roof truss onto a new media centre, Dr Byen, for public radio and TV broadcaster Danmarks Radio The truss would also carry a pedestrian walkway between two sections of the building, spanning a water channel Due to the truss'g cross section it was difficult to calculate the centre of gravity and it could only be lifted where the members connected. The company decided to lift the truss at just three points very close to the centre of gravity ” one at 3.3 m to one side, with the other two located 3.1 m in the opposite direction BMS used a Grove GMK7450 with Mega-Wing Lift and a 100 tonne counterweight on one side to lift the 105 tonne loadat an 8 m radius An unequal length hitch, with an adjustable length link on one sling was used to adjust the inclination of the truss On the other side BMS first used a Demag AC 500-1 with SSL and 140 tonnes of counterweight. When the truss was lifted to about 35 m, clearing the Leibherr LTM 1400 with Superlift and 125 tonne counterweight took over the load via an equalisation yoke The main lifting points were not opposite each other so a slight twist occurred. This was eliminated by adding a Liebherr LTM 1100/1 at one end and a Grove GMK6250 to the lifted a 203 tonne roof truss onto a new media centre, Dr Byen, for public radio and TV broadcaster Danmarks Radio The truss would also carry a pedestrian walkway between two sections of the building, spanning a water channel Due to the truss'g cross section it was difficult to calculate the centre of gravity and it could only be lifted where the members connected.

Mediaco Levage, along with sister companies Mediaco Maxilift Heavy Division and Mediaco Global Services constructed gangways over the fragile 650 m long by 31 m wide terminal building and placed scaffolding inside it A diamond saw was used to cut the building into 146 pieces, weighing 240 tonnes. Each piece was then cut into two 100 tonne sections and one 40 tonne section Over During a seven-month period Mediaco removed some 35,000 tonnes of material, including 3,000 tonnes of steel About 180 employees used the on-site equipment, including a Demag CC 2800 lattice boom crawler crane with 800 tonnes lifting capacity and two 700 tonne capacity Demag AC 700s. Ten further cranes, from 35 to 250 tonnes, were also used, as were 18 m to 40 m access platforms The j ob was finished one month ahead of schedule, despite the stringent safety requirements that came with working in a fully-functional airport.
