First for Crane
A 300 t Liebherr crawler crane is now strengthening the
fleet of the US crane rental company Crane Service Inc.
The company’s first Liebherr LR 1300 SX equipped
with carbon fibre components will be mainly used for
lifting jobs in the wind industry.
It is the first time that the Southwest company Crane
Service Inc. with more than 55 years of experience in
rigging and heavy hoisting has opted for a crawler crane
Mr. Bob Warianka, Business Development Manager
of Crane Service Inc., explains some of the reasons for
purchasing the Liebherr crane:
“The LR 1300 SX is a highly versatile crawler crane.
Furthermore, it offers a better capacity compared
to other crawler cranes in the same tonnage class.”
The LR 1300 SX is additionally equipped with pen-
dant links made from carbon fibre reinforced plastic
(CFRP). Besides being basically
maintenance-free another benefit
of these carbon fibre pendant links
are the increased load charts, asMr.
Bob Strohacker, Branch Manager of
Crane Service Inc. in Sweetwater,
“A key reason for purchasing
the LR 1300 SX was the
opportunity to upgrade the
crane with CFRP pendant
links. They further increase the
lifting capacity of the crane,
thus providing an even better
lifting solution especially for
operating in wind parks.”
In the specific combination with carbon fibre pendants
the crane is able to self-erect 86 m of main boom and a 7 m
heavy duty wind jib. In this configuration the LR 1300 SX is
able to lift a maximum of 75 t at a radius of 15 m.
The première jobsite of the LR 1300 SX is
in a wind park in Nolan, Texas. The crane is
used for hoisting and then again for install-
ing the rotor of five 80 m tall wind turbines
for maintenance works.
Each of the rotors has a weight of ap-
proximately 69 t. The rotors have to be removed in or-
der to replace the gearboxes and main shafts in the wind
The LR 1300 SX is powered by a 390 kW (523 hp)
Liebherr diesel engine. Another distinguishing feature of
this model of the LR series is its enormous
number of boom and jib configurations and
thus potential applications. The combined
length of main boom and luffing jib can be
as much as 169 m, comprising of 56 m of
main boom and 113 m of luffing jib.
