The Tadano ATF 70G‑4 is an all-terrain crane with a maximum lift capacity of 75 tons. The Tadano ATF 70G‑4 offers two separate main boom lengths, either a 5 section telescoping boom reaching 144 feet, or a six stage telescoping boom which measures 170 feet. Both versions of this boom are made with high tensile, fine grain steel and a single telescopic cylinder. All of the sections are extendable under partial load, reducing the amount of time needed to set up lifts. The boom head was created with 6 sheaves that increase the power and lift capacity of the crane. The maximum jib length is 52.5 feet.
The three circuit diesel hydraulic system has both a power controlled axial piston double pump and a double gear pump. The brake system is made up of service disc brakes, parking brakes acting on the 2nd 3rd and 4th axle, and auxiliary brakes. The ZF-Servocom dual-circuit hydraulic steering system has an emergency steering pump. Steering of all axles is possible, and the first two axles have mechanical hydraulically assisted steering.
The frame of both the carrier and the superstructure are torsion-resistant, have a central lubricating system, and are made from high strength, fine grained steel. The frame of the superstructure is connected to the frame of the carrier by a single-row ball bearing slewing ring.
