The 450-ton, six-axle ATF 400G-6 all-terrain crane from Tadano America Corp. can lift 83,800 pounds out to a 46-foot radius with the boom fully extended. It has a 257.5-foot (78-meter) main boom that requires no additional suspension and Lift Adjuster system that reduces tail swing for work in confined spaces. The optional 101.7-foot (31-meter) hydraulic telescopic luffing jib (HTLJ) enables objects to be telescoped beyond building edges and into roofed structures.
The crane is 58.7 feet long, 9.8 feet wide and 13 feet tall (17.9 by 3 by 3.99 meters) and features all-wheel steering and 26,455-pound axle load. Powered by an eight-cylinder, 653 hp Mercedes-Benz Blue Tec engine, the crane has an automatic transmission and delivers 2,213 ft-lbs of torque. The superstructure engine is powered by a six-cylinder, 265 hp Mercedes-Benz Blue Tec engine that delivers 811 ft-lbs of torque.
“All-wheel steering helps reduce tire wear and enables the crane to be maneuvered into confined spaces,” says Thomas Schramm, general manager sales and marketing for Tadano Faun of Germany.
Four outrigger bases with a maximum 304,235-pound counterweight are standard. Safety features include Lift Adjuster and Release Adjuster system designed to minimize load sway. When lifting heavy loads in a small area, the Lift Adjuster is activated, enabling the crane to automatically adjust to the load.
“The Lift Adjuster system enables the operator to use the crane’s automated radius adjustment for minimum sway when the load is picked up,” Schramm says. “This enables the operator to focus on the lift rather than the crane’s instruments. The Release Adjuster positions the boom head above the center of the load.”
The crane is designed to operate under extreme hot and humid conditions. It has a torsion-resistant frame made from fine-grained steel and central lubrication system.
The ZF-TC-Tronic HD TC 3040 SO heavy-duty transmission with torque converter and electro-pneumatically operated dry-type clutch has 12 forward and two reverse gears.
All six axles can be steered and four can be driven (first and sixth are not driven; the third axle has a longitudinal differential lock). The full-width, two-person carrier cab (made of metal and fiberglass) has air-cushioned, adjustable seats (driver seat with heater) and engine-based heater, air conditioning, radio/CD player, and cruise control with hill braking. The superstructure cab has a tiltable cockpit with hydraulically cushioned, adjustable seat with heater, engine-based heater, air conditioning, radio/CD player and LCD graphic display for crane operation.
The electrical crane controls have two joystick levers for simultaneous operation. The five-section, telescopic boom is made of high-tensile, fine-grained steel, consisting of one base section and four telescoping sections that extend by means of a single telescopic cylinder. All telescopic sections are extendable under partial load.
