LIEBHERR A900C CRAWLER EXCAVATOR

Technical Description

The Liebherr A900C is a versatile wheeled excavator engineered for demanding construction and material handling applications. Powered by a turbocharged four-cylinder Liebherr D 924 TI-E diesel engine producing 120 horsepower at 1800 rpm, this machine delivers reliable performance in diverse working conditions. The excavator operates on a variable displacement swashplate hydraulic system with a maximum flow capacity of 71.4 gallons per minute and relief valve pressure of 5,076 psi, enabling rapid cycle times and responsive control. Weighing approximately 39,242 pounds in operating configuration, the A900C features interchangeable boom-and-stick options to accommodate varying job requirements. Maximum digging depths range from 17.8 to 19.4 feet depending on attachment configuration, while maximum reach along ground level extends to 30.9 feet. The bucket system accommodates capacities between 0.42 and 1.24 cubic yards, with a reference capacity of 0.7 cubic yards for general applications. Equipped with an oversized two-speed power shift transmission incorporating creeper functionality, the machine achieves maximum travel speeds of 12.5 miles per hour on roadways. The hydraulic swing mechanism operates at 9 revolutions per minute with swing torque rating of 31,000 foot-pounds, facilitating efficient material placement. Ground clearance of 0.1 feet and a 7.5-foot tail swing radius minimize site disruption while optimizing maneuverability. The 84.6-gallon hydraulic fluid capacity and 79.3-gallon fuel tank enable extended operational periods between service intervals. The machine's integrated 55-ampere alternator supports auxiliary systems, while 24-volt electrical architecture powers all operational circuits. Built with high-tensile steel construction and Liebherr's proprietary Litronic control system, the A900C delivers exceptional productivity with reduced fuel consumption.
