The Liebherr LTM 11200-9.1 of Mammoet used by the disassembly of a wind mill at the Maasvlakte (NL).
The crane is here fitted in T7YVEF formation, with long guyed main boom and short fixed jib under angle.
When the windmill blades are attached the crane boom boom is retrackted and extended to work with another boom length. At the left a Liebherr LTM 1120/1 of BKV, the principal.
The boom is extended 76.7 meters here, 9.1 meters of main boom extension and 6.5 meters fixed jib under 30 degrees.
The wings of the GE wind mill are attached to the lifting frame. The boom guying is attached to the main boom extension.
The windmill is disassembled because he must yield for the entry to the 2nd Maasvlakte.
Tilting the star, weights about 50 tonnes.
A view at the 9 axle undercarriage. During transport over the road the boom is transported separatly by truck.
Appositely the crane has park number 1200, analogous to the lifting capacity. This is the first delivered LTM 11200-9.1 all over the world in September 2009.
The crane is fitted with all the counterweight, 202 tonnes. With a tail swing of 9.15 meters.
The outrigger dimensions are 13 x 13 meters.
The upper cab is attached to a small boom and in height adjustable. The machinist can lower it to the ground. The cab is made out of a composite material to reduce weight.
An impressive crane.
The Liebherr LTM 11200-9.1 of Mammoet used for hoisting beams for a new fly-over together with a Terex AC 700, also of Mammoet.
Fitted with YSL boom guying and 36 metres of luffing jib.
Some beams are hoisted on this project before using other cranes.
Fitted with 182 tonnes of counterweight, extendable to 202 tonnes.
The outrigger base is 13 x 13 meters.
The undercarriage engine is a 8 cylindre Liebherr engine with 680 hp. The crane has fleetnumber 1200 by Mammoet.
By using the luffing jib, the YSL guying is 90 degrees folded. The guying is then 23 metres wide.
The beams weight about 180 tonnes.
It is not possible to use the luffing jib on a retracted main boom.
