The Tadano AC 4.070L-1 all-terrain crane replaces the ATF 70G-4 with a lifting capacity of 75 tons.
The six-section main boom provides 171 feet of lifting length, at which it can lift 12,786 pounds. A main boom extension has a length of 29.5 feet to 52.5 feet. It can be used at 0 to 40 degrees to overcome obstacles.
The Lauf carrier cab has been enhanced and the superstructure controls use the AML-F crane control system. The control system provides short setup times, according to the company, and ensures a high degree of flexibility when it comes to positioning the crane thanks to asymmetrical outrigger setting capabilities. The crane selects the optimal extension sequence for each radius by itself. The Tadano Lift Adjuster provides greater convenience during lifting by reliably reducing load swinging during lifting and lowering.
The AC 4.070L-1 all terrain crane can be configured for a wide variety of axle load limits. Without a main boom extension and with 9,700 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 travel with up to 26,900 pounds of counterweight.
The two-engine design pairs with a ZF TraXon transmission, including rock-free and hill start assist functions.
