Liebherr LTR 1100 - Albert Regel
A Liebherr LTR 1100 of Albert Regel from Baunatal (DE) used by the assembly of precast concrete elements.
It is a 100 tonne telescopic crane on a crawler undercarriage. The year of manufacture is 2006.
The undercarriage has extended a 5.05 meter width and retracted a width of only 3.5 meters.
Between the tracks is on both sides a slab central counterweight woth 7.5 tonnes mounted, in total are 15 tonnes of central counterweight mounted.
The tracks are 6.4 meters long, 0.9 meters wide and 1.2 meters height. Their mass each is 9.7 tonnes.
The crawler undercarriage comes from the production of Liebherr in Nenzing (AT) and is also used by the LR 1100. The superstructure comes from the Liebherr production in Ehingen (DE), from this plant are the cranes also delivered.
Fitted with 32 tonnes of counterweight, exists out of two wide 10 tonne slabs and above four smaller slabs with each 3 tonnes. The counterweight has a 4.42 meter tailswing.
This crane is equiped with teh second hoist winch, that weights 1.3 tonnes. The second winch could be reefed over the boom extension, loads can than be tilted with two hooks in the air. In this case the second winch wasn't used. When the second winch is removed, than a replacement counterweight with 900 kg will be mounted here.
To reduce the transport mass (and width), the tracks could be removed. The crane jacks itself up using these four smaller jacks. With use of it's own hook the tracks can be mounted of removed. The transport mass with tracks is 55.2 tonnes and without the tracks is it 37.1 tonnes.
The boom has a 11.5 meter base length and is extendable up to 52 meters. The boom is here 15.2 meters extended. Next to the boom is hanging a small erection jib with a 2.9 meter length. This jib is often used in combination with the second winch to tilt e.g. large pillars. Over this erection jib can still 34.5 tonnes be lifted. A double folding jib with a 19 meter length, in combination with 14 meters of boom extension makes a maximum hook height of 84 meters possible.
This type of crane is often used by the assembly of precast concrete elements or the assembly of crawler cranes by the erection of wind turbines.
