The heavy lift and transport specialist Mammoet has taken delivery of its first Demag AC 55-3 all terrain crane. “The main reason why we chose the Demag AC 55-3 is its outstanding lifting capacity. In addition, the AC 55-3 is an extraordinarily robust and reliable crane, as our Dutch colleagues have confirmed,” explained Vitor de Costa, part of Mammoet’s Fleet Maintenance staff, who picked up the crane in Zweibrücken together with crane operator Alexander Morasch and was handed over by Terex Cranes Key Account Senior Sales Manager Uwe Schlicher.
The Demag AC 55-3 will be used at the BASF factory premises in Ludwigshafen, Germany.

Since two years and a half, the French subsidiary of the Vernazza Autogru company is using a Terex RT 90 rough terrain crane in the construction jobsite of the International Thermonuclear Experimental Reactor in Cadarache. This machine has a 86t lifting capacity and its boom has a maximum reach of 47m. Its quick installation in 20 minutes and its great reliability have been very important points to chose this crane. “(…) The RT 90 with its width of only 3m is the most compact crane of this type on the market. This, too, made it our first choice for this construction site. It also has the intuitive IC-1 control system, which ensures precise crane movements, and has an innovative diagnostic function,” explained Paolo Delfino, General Director of Vernazza Autogru France. On this job site, the RT 90 has been requested to lift until 60t with a reach between 12 and 35m.
In Turnhout, Belgium, multiple apartments buildings and a museum are under construction and will form the Turnova District. To erect them, the Dutch crane rental company Stravers Torenkranen B.V has been chosen on behalf of the construction company Interbuild N.V. They are currently using six Terex flat-top tower cranes to do so, including two CTT 332-16 and four CTT 231-10. The first one has a 16t maximum lifting capacity and 3t at maximum length, with 75m of jib length. The second flat-top tower crane can lift until 10t and 2t at 70m high. To bring the cranes to the job site, Stravers used 72 trucks from its location in Veghel, in the South of Netherlands. A team of four people erected the six cranes during six full days. They will stay on site during a year and a half to lift prefab components, building materials and concrete buckets. The Owner and General Manager from the Dutch company, Berry Stravers, explained why he chose the CTT. “There were two reasons why we decided to only use Terex cranes for this work site: Firstly, they had the required lifting capacities. Secondly, it was remarkably easy to position them in an overlapping arrangement on the available space.” In total, almost the entire Stravers fleet is made up of Terex tower cranes (120 on 130).
The British premium crane service provider for mobile cranes RRC Cranes Hire Ltd, with Road Rail Cranes Ltd, has just extended its fleet with a new Demag AC 300-6 all terrain crane, unseen in United Kingdom. This 300t model (350 US ton) combined strength with the ability to lift 15t on a full meter boom. “Since adding our first specialized crane in early 2013, we’ve worked hard to build an impeccable reputation for network rail infrastructure,” said Ian Cross, managing director for RRC. “From the very beginning, we knew the company would be successful if we employed highly trained operators and equipped them with quality and innovative equipment. The Demag AC 300-6 all terrain crane exemplifies those standards and will be a great addition as we continue to grow as a company.” In total, RRC Group owns and operates more than 24 Terex and Demag cranes.
The French brewery Goudale recently called on Action Lev from Calais to install 24 new fermentation tanks in its craft of Arques, in Northern France. The lack of space which reduced the crane’s leeway was a major issue. To solve it, the lifting company used two Demag all-terrain cranes AC 100-4 and AC 160-5, respectively with a 100 and 160t capacity, and lifted in tandem. First, the four axled AC 100-4 with a compact design lifted the lower section of the tanks. Then, the other crane has been installed on a raised concrete floor dedicated to receive the new tanks to put the AC 160-5 at the nearest of their final position. « This ingenious solution let the access corridor available for the 6m convoy and the AC 100-4 positioning », summed up Jean-Christophe Accio, Sales Manager for France of Terex Cranes. Configured with counterweights respectively with 26,1 and 46t of maximum capacity, both Demag enabled the team to install six tanks a day thanks to this combination and finish the task in three days.
McGovern Crane Hire, located in Derbyshire in central England, has successfully raised a 21-tonne generator on the grounds of the Birmingham Children’s Hospital. This lifting presented a major challenge. The team could have used a large crane with a minimum lifting capacity of 350 to 500 tonnes but the extremely tight space conditions, an aisle of the hospital, made impossible the use of a crane with sufficient performance for a lifting of this weight. The solution found by the Mc Govern teams was using a Demag AC 220-5 all-terrain crane that was compact enough to fit in the driveway, yet with the innovative IC-1Plus control system, it offered sufficient lifting power with asymmetrically configured outriggers.
In order to lift the load with its weight of 22 tonnes, including hook block and lifting tackle, the AC 220-5 was equipped with a counterweight of 51 tonnes. The outriggers were set to meet the needs of the job site. Thus, it was possible to lift the generator at a boom length of 33.3 meters and a radius of 15.0 meters off the lowbed trailer in the driveway to a height of 10.0 meters. It was then lifted over adjacent buildings by slewing the crane directly over the front right rigger which was fully retracted, the crane continued slewing right on the right until over the back right rigger which was extended to three quarters and easily lowered down at the desired location with a final radius of 19.7 meters.
“Thanks to the IC-1 Plus, however we were able to configure the crane to carry out the lift utilizing only 84% of the rated lifting capacity while using reduced counterweight, ”
Crane service provider Wiemann, based in Dortmund, has expanded its fleet with a new Demag AC 100-4L all terrain crane for its location in Gierstädt. This machine, with a capacity of 100 t and a main boom of 60 m (with a boom extension of 19 + 8 m), is one of the most compact cranes in its class. “With a width of only 2.55 meters, the AC 100-4L is the most compact crane in its category, making it ideal for work sites where space is tight,” explaining his purchase decision General Manager Martin Wiemann, who has received the crane together with employees Georg Ruhe and Mario Bley at Terex Cranes in Zweibrücken.
