With a 259.2-foot-long main boom, Tadano’s new five-axle AC 5.250L-2 all-terrain crane offers plenty of reach in a compact package for urban jobsites.
It has a maximum main boom extension of 98.4 feet, with all main boom extensions from 19 to 98.4 feet being self-erecting. The available maximum system length of 357.6 feet allows the crane to easily lift loads over obstacles and onto tall buildings or help assemble large tower cranes, Tadano says.
“Our AC 5.250L-2 is also top of the class when it comes to load moment, which at up to 736 metric tons is one of the best on the market,” said Peter Kleinhans, Tadano project manager. “This high load moment is achieved with a working radius of 23 feet, a 44.3-foot-long main boom and a load weight of 231,920 pounds.”
An optional heavy-lift attachment can handle loads up to 305,780 pounds on the short boom with additional sheaves.
Use as a Taxi Crane
Tadano says the AC 5.250L-2 is just as easy to transport as the AC 5.250-2 model it is based on. A 530-horsepower Mercedes-Benz engine with maximum torque of 1,917 pound-feet powers both models.
In Eco Mode, the engine only delivers as much power as the crane needs at any given time. Standard hill start-assist eases starting and maneuvering on inclines.
The crane with 10 x 6 drive can be moved on 16-inch steel wheels on public roads while remaining in compliance with the 26,500-pound axle load limit. With a 10 x 8 drive, it meets the 36,400-pound-per-axle limit. Both configurations can also carry additional equipment and gear and remain within the limits.
Easy Counterweight System
The AC 5.250L-2 can pick up its maximum counterweight of 176,400 pounds in three lifts: 109,300
