Terex Demag's new AC 100/4, which the company bills as “the strongest four-axle 110-ton crane on four axles with maximum counterweight,” for lifting capacities with fully extended telescopic main boom and main boom attachments. It's the first and only crane in its class to have a vehicle breadth of just more than 8 feet, even with mega-size tires 16.00R25. The 110-ton crane is the same compact size as its 77-ton four-axle cousin.
The AC 100/4 reaches a maximum load moment at 308 metre tonnes, with ultimate lifting capacity at 110 tons. The crane's system length stretches to more than 252 feet via a 164-foot, five-section telescopic boom plus 88-foot main boom extension. At a medium length of 109-feet plus maximum counterweight the crane hoists 27 tons within a 32.8-foot radius, and still manages 6.7 tons at 98 feet. At a 32.8-foot radius the crane has a lifting capacity of 13.2 tons, while at a 98-foot radius it's 5.8 tons, with the boom fully extended and 28.8-ton counterweight.
Also in transport mode with 13-ton axle load, 6-ton counterweight, 62-foot main boom extension and 16.00R25 tires, the machine is built to deliver performance. At 32.8-foot working radius with 164-foot main boom it manages 13 tons.
The vehicle's width of 8.4 feet and the length of 34 feet permit maximum variability on the job. This opens up new, viable applications for customers, such as rapid machine assembly and dismantling, or utilization in refineries. At less than 13 feet, the crane has the tightest counterweight swing radius in its class.
The variable outrigger system allowing each beam leg to be set in any one of four different positions provides adaptability in coping with uncompromising environments. Performance levels are supremely maintained, even in tight corners when one or several legs may be impeded from full extension.
A water-cooled DaimlerChrysler engine provides 445 hp. With its 7 KW/t, it boasts one of the highest power-to-weight ratios of all known four-axle mobile cranes. The power train design increases vehicle mobility. On the highway, through shorter starting and drive-away times, and off-road • off-road capability is ensured through the front axle (which can be activated when needed) and rear axle lines being drive axles.
The independent upper carriage power train with 175 hp provides a balance between high performance for rapid and/or four simultaneous operational movements and low fuel consumption. Thanks to high torque there's no need to work with the engine in fuel-guzzling full-load mode. The power train design comes from the next-size-up five-axle series AC 100 through AC 160-2 and thus disposes of huge reserves of performance. The AC 100/4 works with a 164-foot-long main boom with four inner sections. The result: fastest times for telescoping out to the full boom length, as there's one telescopic cycle fewer.
The AC 100/4 is fitted with the most versatile main boom extension (MBE) in its class. The 62-foot MBE can be offset both at the main boom and at the 26-foot extension. “Hydraulic offsetting” is also available as an optional extra. The crane also offers the possibility of also offsetting the 26-foot extension to permit either large radii or the overcoming of awkward protruding edges.
