TNT BuYS DEMAG AC 700-9 ALL TERRAIN
Houston, Texas-headquartered crane service provider TNT Crane & Rigging has bought a 700 tonne class capacity Demag AC 700-9 all terrain crane, supplied by Houston-based Demag dealer CraneWorks.
TNT bought the crane to replace an older AC 700-9, with the new model featuring Tadano’s IC-1 Plus control system, which automatically calculates the crane’s capacity on the fly, accounting for multiple outrigger and counterweight configurations. It is now the company’s third AC 700-9. “The CraneWorks team did an
awesome job helping us secure and deliver our new AC700,” said Kevin Lawson, vice president of operations at TNT Crane & Rigging. “They were there every step of the way to assure the commissioning process proceeded
smoothly and we were able to put the crane to work with no issues. “The crane was picked up on a
Tuesday morning, TNT’s expert crew had it fully assembled in multiple configurations and certified by Saturday evening, and it went straight to work the next week,” said Randy Harris, the CraneWorks salesman who oversaw the transaction. “There aren’t many machines this size that go from sitting in crates to the jobsite that quickly. It’s a credit to Tadano Demag’s engineering, to the service techs from Tadano and CraneWorks who were onsite for hands- on support, and to TNT’s unparalleled knowledge of the AC 700-9 that the crane was work ready so fast.” “We deal with trade-ins every day, but
I can’t remember the last time someone asked us to sell them the same model
they were trading in. It was exciting to work with the crew over at TNT on this project, especially since it was the largest all terrain crane we’ve ever sold,” said Keith Ayers, CEO of CraneWorks.
CANADIAN BRIDGE DISMANTLING WoRK
International heavy lift and transportation specialist Mammoet has been contracted by Canadian consortium Nouvel Horizon Saint-Laurent (NHSL) – which is made up of construction company Pomerleau and demolition specialist Delsan-AIM – to work on four different stages of the Champlain Bridge deconstruction project managed by the federal corporation The Jacques Cartier and Champlain Bridges Incorporated. The project is taking place in Montreal, Quebec, Canada. The first span of the original
Champlain Bridge was successfully taken down in early July. Around ten spans have been removed so far. For this Mammoet arranged a jacking
system between a client-supplied catamaran barge and a demolition platform to lower concrete bridge deck sections weighing 1900 tonnes. Mammoet has provided six of its in-house developed jacking towers to effect this. Each tower of Mammoet’s MJS-800 system has an 800-tonnes capacity. The jacking towers are removing bridge deck spans as high as 25 metres (82 feet) above water level. Depending on weather conditions, the demolition of a span lasts around seven days. At sections of the bridge where the water is too shallow for the barge and jack combination, this same system will be used to remove concrete bridge deck sections on temporarily reclaimed land. In this second stage the barge will be
replaced by Mammoet’s self-propelled modular transporters (SPMT) to move

the bridge sections away from their piers. The third stage is the removal of the steel truss sections above land with the same jack and SPMT combination. Additionally, the job includes the
removal of the steel truss bridge’s main span over the St. Lawrence Seaway. The 2,000 tonne (4,409,245 lb.) steel structure will be lowered down onto a barge using six Mammoet strand jacks. The final challenge of the project will be to remove concrete bridge spans which are located over a busy highway. These spans will be safely removed over a weekend during a rapid bridge replacement – an activity which Mammoet said it has successfully performed multiple times in Canada and all over the world.
