LTR 1220 5
Economic transportation and easy assembly
Optimised weights and dimensions
The basic crane with 1 m wide crawler carriers has a weight of app. 91 t without
ballast. Without crawler carriers the unit weighs app. 55 t including the jack-up
cylinders and the traverse beams. It is only 3 m wide and 3.3 m high. By self-
contained disassembly of the traverse beams the weight can be reduced to
app. 48 t (option). Thus the economic transportation is warranted even in coun-
tries with restrictive weight regulations.
The crane assembly is carried out optionally by self erection. The basic machine
is transported by low-bed trailer to the job site and then supports itself on the
jack-up cylinders (option). Central ballast, traverse beams, crawler carriers and
superstructure ballast are mounted without auxiliary crane.
