LIEBHERR R954C LITRONIC CRAWLER EXCAVATOR

Technical Description

The Liebherr R 954 C Litronic is a heavy-duty crawler excavator designed for demanding construction and demolition applications, offering robust performance and advanced technology. Powered by a Liebherr D 936 L six-cylinder in-line diesel engine with a displacement of 10.5 liters, turbocharged and after-cooled, it delivers a net power output of 240 kW (322-326 hp) at 1,800 rpm, compliant with Tier 3 / Stage IIIA emission standards. Its engine features state-of-the-art common rail injection, LIDEC electronic engine control, incline lubrication enabling operation on slopes up to 100%, and optimized combustion for fuel efficiency and reduced emissions. The operating weight ranges between approximately 49,200 to 57,000 kg (108,000 to 126,000 lbs) depending on attachment and configuration, with a bucket capacity from 1.3 to 3.5 cubic meters, providing high digging and break-out forces supported by large stick and bucket cylinders. The hydraulic system employs two variable flow, swash plate pumps with a maximum combined flow around 700 l/min and pressures up to 384 bar, enabling simultaneous operations with high precision and efficiency. It incorporates advanced functions such as Regeneration Plus for faster arm lowering and energy savings, and a hydrostatic fan drive with thermostatically controlled fans to optimize cooling and fuel consumption. The undercarriage is robust with 600 mm track pads, lifetime lubricated rollers, and improved self-cleaning, ensuring stability and reliability across varied terrains. The cab is ergonomically designed, soundproof, and climate-controlled, equipped with extensive safety features including handrails and safety valves on boom and stick cylinders. Additional attributes include an electronic pump regulation system, hydraulic quick couplers, and multiple hydraulic circuits for diverse attachments, making the R 954 C Litronic a versatile, powerful machine for excavation and demolition tasks.
