Tadano Faun Crane ATF 90G-4 Parts Catalog

Tadano Faun Crane ATF 90G-4 Parts Catalog PDF VEHICLE/EQUIPMENT INTRODUCTION: The Tadano Faun ATF 90G-4 is a 90-ton capacity all-terrain mobile crane designed for demanding construction and heavy-lift operations worldwide. Tadano acquired Faun's mobile crane division to create a powerhouse in the European all-terrain crane market. The ATF 90G-4 combines German engineering with Japanese reliability, offering a versatile four-axle machine with excellent mobility on both paved roads and rough job sites. This crane features a multi-section telescopic boom with significant reach, a robust counterweight system, and a load moment indicator that ensures safe operation across all working ranges. The ATF 90G-4 is built on a rugged FAUN carrier chassis with all-wheel drive and all-wheel steering, providing superior maneuverability on confined job sites. With a combination of a high-torque diesel engine, automated transmission, and advanced hydraulic systems, this crane operator has the tools to execute complex lifts safely and efficiently.
