Successor to the successful ATF 70G-4, the AC 4.070-1/ AC 4.070L-1 was designed with a strong focus on versatile and comfortable operation. It features a new carrier cab, a multifunctional crane control system, and engines that conform to EU Stage V requirements.
With its AC 4.070-1 and AC 4.070L-1, mobile crane manufacturer Tadano is introducing an upgraded four-axle all terrain crane with a lifting capacity of 75 ton and two boom lengths.
Successor to the successful ATF 70G-4, the crane was designed with a strong focus on versatile and comfortable operation. It features a new carrier cab, a multifunctional crane control system, and engines that conform to EU Stage V requirements.
As part of its reorganization efforts, Tadano will be standardizing the names of its mobile crane models throughout the year. The new AC 4.070(L)-1 adheres to the new naming conventions right out of the gate.
Above All: Powerful Performance Characteristics
With a length of 171 ft. and a six-section main boom, the crane can lift 12,786 lbs. at its full boom length. The lifting capacity was especially improved further for steep main boom positions with small radii. A 144 ft. 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, the manufacturer said.
Quality Equipment for a Quality Crane
Customers who acquire the new AC 4.070(L)-1 also benefit from the enhanced characteristics of the latest carrier cab from Lauf and the identical superstructure controls using the AML-F crane control system.
No sacrifices when it comes to equipment, quality, or versatility: That is the Tadano motto. And a main boom extension (HAV) with a length of 29.5 to 52.5 ft. proves it, the manufacturer said.
With manual or step-less hydraulic adjustment capabilities, it can be used at 0 to 40 degrees 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 ft. 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 due 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.
Light on the Road
Due to the ability to flexibly subdivide its counterweight, the AC 4.070(L)-1 can be configured very precisely for an extremely wide variety of axle load limits. Without a main boom extension and with 9,700 lbs. of counterweight, the crane can comply with the 11 ton axle load limit that is becoming increasingly more common. When staying under a 13 ton axle load limit instead, the crane can even travel with up to 26,900 lbs. of counterweight.
The range of axle load limits that can be complied with goes all the way up to 36,376 lbs. so that the crane can travel on U.S. roads, for example.
A State-of-the-Art Engine Combination with a Tried-and-True Design
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. 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 manufacturer said.
