At ConExpo this year, Terex introduces theDemagAC 100/4 for the first time to the US market. The company says the AC 100/4 is the strongest 100 metric ton (112 ton) four-axle crane (at maximum counterweight) on the market.

The maximum load moment of this mobile crane is 308 tonne meters, its system length is 77 meters (252 feet), with a 50 meter (164 foot) telescopic boom plus 27 meters (88 feet) of main boom extension. With a dolly, the crane is roadable in almost every state in the US with the distance between axle two and three at 8 feet and 16 inch tires.

The compact steel design is of significant advantage, the company says, with 100 metric tons (112 tons) distributed on 4 axles.

Stabilizer options

The AC 100/4 has the most variable main boom extension (HAV) in its class, and the 19-meter (62.3 foot) HAV can be offset at the basic boom as well as at the 8 meter extension, the company reports. The ability to also offset the 8 meter extension is a unique aspect of the machine, making it possible to either achieve a larger radius or to lift loads over projecting edges.

Four different stabilizer bases come as standard on the machine, giving it a higher degree of flexibility in challenging operating environments. The carrier engine is a liquid-cooled DaimlerChrysler unit, delivering a powerful 335kW / 445 HP @ 2,000 RPM. The separate superstructure engine with an output of 129 kW / 175 HP provides an excellent balance of power for rapid working cycles and low fuel consumption.
