The 630 EC-H 70 Litronic
Tower cranes for wind turbines
The 1000 EC-B 125 Litronic
Liebherr has developed special tower cranes for assem-
bling wind turbines. These cranes feature economical
transport, low area requirement for erection and precision
operation even in high wind speeds. The innovative solution for the use of tower cranes for
assembling wind turbines was developed in 2011. Sev-
eral wind turbines have already been erected using the The new 1000 EC-B 125 Litronic Flat-Top crane can lift a maxi-
mum of 125 tonnes and has been completely designed for
assembling wind turbines. 630 EC-H 70 Litronic. Its maximum lifting capacity of
70 tonnes has already been used for wind turbines with a hub
height of approx. 140 metres.
Guying
Despite the enormous
height the cranes only have
to be guyed once to the
tower depending on the
job in hand.

Everything in view
A perfect view of the load
makes it easier for the crane
driver to position units precisely.
Step by step
The tower crane
climbs into the air
quickly and safely.

Arrive safely
The logistics cost for transporting a tower crane is much
lower than for comparable crane systems. Conventional
semi-trailers are usually all that is required.
Simply well-placed
One of the main features of tower cranes is their low space
requirement. The area requirement for erecting the crane
is around 50 % of other crane systems.
High working speeds
The high performance hoist gear makes a major contribu-
tion to the economical use of the cranes. Loads can be
lifted at speeds of up to 37 m/min.
