The longest boom crane in the world is currently the
Liebherr LTM 11200-9.1, which is a mobile crane with a telescopic boom that can
reach a maximum length of 100 meters (328 feet). The crane is manufactured by
the German company Liebherr Group and is capable of lifting a maximum load of
1,200 metric tons (1,323 US tons).
The LTM 11200-9.1 has a nine-axle chassis and can be driven
on public roads, making it a highly versatile machine for heavy lifting
operations. It is commonly used in the construction of wind turbines, for
example, where it can lift heavy components such as tower sections and nacelles
to great heights.
In addition to its impressive length and lifting capacity,
the LTM 11200-9.1 is also equipped with advanced safety features, such as a
computerized load moment limiter that helps prevent overload situations and a
system that monitors the stability of the crane during operation.
It is worth noting that the Liebherr LTM 11200-9.1 has held
the title of the world's longest boom crane since it was first introduced in
2007. However, other manufacturers, such as Manitowoc and Terex, have also
produced cranes with impressive lifting capacities and boom lengths, and the
title of the world's longest boom crane could potentially change in the future
as new and more advanced cranes are developed.
Technical Specifications: The Liebherr LTM 11200-9.1 crane
has a maximum lifting capacity of 1,200 metric tons (1,323 US tons) and a
maximum boom length of 100 meters (328 feet). The crane can be equipped with a
variety of jib extensions and other attachments to further enhance its lifting
capabilities.
Mobility: The crane is mounted on a nine-axle carrier and
can be driven on public roads. It has a maximum speed of 85 km/h (53 mph) and
is equipped with a hydraulic suspension system that ensures a smooth ride even
over rough terrain.
