LIEBHERR A920 CRAWLER EXCAVATOR

Technical Description

The Liebherr A920 Litronic is a Generation 6 wheeled excavator engineered for versatile construction applications, combining robust performance with operational efficiency. This machine features a powerful 4-cylinder diesel engine delivering 129 kW (175 HP) at 1,800 rpm, compliant with Stage IIIA and Tier 3 emission standards. The excavator operates at an approximate weight of 20,700 kg (45,700 lbs), providing a balanced platform for stable digging and lifting operations across variable terrain. The A920 Litronic delivers exceptional digging capabilities with maximum digging depths reaching 6.35 meters (20.4 feet) and ground-level reach extending to 9.75 meters (31 feet) depending on stick configuration. Maximum digging force reaches 98.4 kN (10.0 metric tons) with the shortest stick option, while breakout force capability achieves 160.5 kN (16.4 metric tons) with ripper bucket attachment. The excavator accommodates bucket capacities ranging from 0.55 to 1.20 cubic meters, offering flexibility for diverse material handling tasks. Advanced features include a constant-power hydraulic system with combined fluid movements, ensuring continuous high performance in demanding ground conditions. The machine incorporates multiple operational modes—Sensitive, Eco, Power, and Power-Plus—enabling operators to optimize performance and fuel consumption based on specific job requirements. Travel capabilities include stepless speeds up to 20 km/h on-road and 7 km/h off-road, with a pulling force of 127 kN. The ROPS safety cab structure provides operator protection, while the dual-circuit braking system with load-holding valves on each stabilization cylinder ensures reliable machine control and safety during operations.
