Tadano will be standardizing the names of its mobile crane models throughout the next year. The new AC 4.070(L)-1 adheres to the new naming strategy.
With its AC 4.070-1 and AC 4.070L-1, Tadano is giving the market an upgraded four-axle all terrain crane with a lifting capacity of 75 tons and two boom lengths. The new crane is a successor to the Tadano ATF 70G-4. The new model was designed with a strong focus on versatility and comfortable operation, the company said. It has a new carrier cab, a multifunctional crane control system, and engines that conform to EU Stage V requirements.
As part of its recent reorganization, Tadano will be standardizing the names of its mobile crane models. The new AC 4.070(L)-1 adheres to the new naming plans.
With a length of 171 feet, the crane features a six-section main boom. At its full boom length, the crane can lift 12,786 pounds. The lifting capacity was especially improved further for steep main boom positions with small radii, Tadano said. A 144 foot main boom continues to be available as an option.
“With all this, Tadano sticks to its promise of offering its customers a powerful and versatile heavy-duty all-rounder that is nevertheless extremely compact,” Tadano said.
The new AC 4.070(L)-1 is designed with the latest carrier cab from Lauf and the identical superstructure controls using the AML-F crane control system.
The main boom can extend from 29.5 to 52.5 feet. With manual or step-less hydraulic adjustment capabilities, it can be used at 0° to 40° to overcome an extremely wide variety of obstacles. In addition, the larger total lifting capacity continuously changes in line with all radii. An additional 5.9-foot runner can be mounted on the opposite side of the double swing-away jib on the boom.
Getting Work Done Fast
The intuitive and precise AML-F crane control system makes it possible to achieve short setup times to get going quickly and ensures a high degree of flexibility when it comes to positioning the crane thanks to asymmetrical outrigger setting capabilities. The automatic lifting capacity selection function makes things much easier for crane operators. The crane selects the optimal extension sequence for each radius by itself. In addition, the Tadano Lift Adjuster provides greater convenience during lifting by reliably reducing load swinging during lifting and lowering – a very useful aid for all crane operators.
With this crane, the counterweight can be subdivided and can be configured very precisely for an extremely wide variety of axle load limits. Without a main boom extension and with 9700 pounds of counterweight, the crane can comply with the 11-ton axle load limit. When staying under a 13-ton axle load limit, the crane can even travel with up to 26,900 pounds of counterweight. The range of axle load limits that can be complied with goes all the way up to 36,376 pounds so the crane can travel on roads in the U.S.
The AC 4.070(L)-1 benefits from a reliable and cost-effective two-engine design featuring the latest exhaust emission control technology in conformity with EU Stage V, Tadano said. Together with a ZF TraXon transmission, including rock-free and hill start assist functions, the maneuverable crane can handle even the tightest spaces and meet the needs of even the most demanding customers, the company said.
The crane has a tip height of 233 feet and a radius of 170.6 feet. The carrier engine is a Mercedes-Benz OM 470 LA, 456 HP / 340 kW, EU Stage V and the superstructure engine is a Mercedes-Benz OM 934 LA, 175 HP / 129 kW, EU Stage V. The crane features an: 8 x 6 x 8 (8 x 8 x 8) drive. It is 41.3 feet long, 8.5 feet wide and 12.7 feet tall.
