Terex Introduces Long-Boom All-Terrain Crane


Terex Cranes, Zweibrucken, Germany, has introduced the AC 100/4L all-terrain crane, featuring a main boom with a length of 195 feet. The compact crane is optimized for a broad range of applications. Together with its variable extension system, the crane reaches an impressive maximum system length of 268 feet. The 110-ton AT sets a new standard by combining capacity with standard truck dimensions, so that it has a width of only 8 feet when equipped with large 445/95R25 tires. With a 195-foot telescopic boom and a 62-foot double fly jib, the AC 100/4 L achieves the longest system length (257 feet) that can travel on four axles with an axle load of 13 tons or less. And, the crane’s maximum system length is an impressive 268 feet.

“Our customers wish for both compactness and long system lengths in a crane – with the AC 100/4L we have a crane available that is easy to operate and meets our customers’ demands,” explains Thomas Hartmann, sales director, Terex Cranes. 

The AT is equipped with a variable system used for extending its main boom. The 62-foot-long double fly jib enhances the crane’s versatility, as it can be mounted directly on the telescopic boom or on an additional 26-foot extension installed between the telescopic boom and the double fly jib. The system makes for fast rigging on the jobsite, as the 62-foot double fly jib can be transported within a 13-ton axle load.

Taking the crane’s flexibility one step further, Terex engineers designed the crane in such a way that the 62-foot double fly jib can not only be offset by itself on the extension: it is also possible for the entire 88.5 feet, i.e., the 62-foot-long double fly jib and the 26-foot-long extension together, to be offset on the telescopic boom. This novel approach makes it possible to either work with a large working radius or to overcome projecting edges of up to 206 feet. To top it all off, there is an available option that makes it possible for the 62-foot-long double fly jib to be offset hydraulically, which provides even more operational flexibility of the crane.

The AC 100/4 L is designed for a wide range of applications. Its compact dimensions also make it an ideal machine for projects involving tight spaces, which otherwise could be reached only by smaller-class cranes in some cases. Since the crane can achieve high lifting capacities within an axle load of 13 tons, such as without the need for transporting additional equipment, it can also be used effectively in operations involving lifting capacities as small as approximately 55 tons.

The crane’s telescopic boom, measuring nearly 197 feet, enables it to handle jobs that previously required a significantly larger five-axle machine from the 143-ton class, according to the company. Four standard outrigger bases provide a maximum degree of flexibility under demanding operating conditions. The machine’s capabilities can be achieved even when there are space constraints that prevent the outriggers from being fully extended. A 445-hp Daimler engine powers the crane’s road-traveling capabilities and keeps fuel consumption low.
