L. Walter & Sons Excavating has strengthened its quarry operations with the addition of a Liebherr R 992 crawler excavator, a move aimed at improving power, efficiency, and productivity in tough working conditions.
Operating in a solid rock quarry with heavy, abrasive materials, the company needed equipment built for demanding extraction. The R 992 stood out as the ideal choice. Its powerful performance allows it to load 40-tonne trucks in just three passes, reducing downtime and cutting operating costs.
“What won us over was the combination of power, speed, reliability, and production quality. The R 992 checks all these boxes,” said Matt Walter, Vice President of L. Walter & Sons Excavating.
Built for Power and Efficiency
The 94-tonne R 992 is designed for challenging environments. It features improved diesel efficiency and advanced operator assistance systems. Its 6.2 m³ bucket and strong breakout force allow for fast and efficient rock loading, while protective plates safeguard the machine during block handling.
The operator’s cab includes two cameras, armoured windscreen, and Bucket Fill Assist technology, improving safety, visibility, and cycle times.
Liebherr 70–100 Tonne Series
The R 992 is part of Liebherr’s large crawler excavator lineup, including the R 972, R 978 SME, and R 998 SME. These machines combine power, precision, and fuel efficiency, supported by Liebherr Power Efficiency – Engine Control, which optimizes performance while reducing fuel use and emissions.
With advanced comfort, intelligent controls, and strong environmental performance, the R 992 gives L. Walter & Sons Excavating a reliable and cost-efficient edge in quarry operations.
