Liebherr R 936 – Crawler Excavator with D936 A7 Engine

The Liebherr R 936 is a high-performance crawler excavator in the approximately 35–40 ton class, designed for demanding earthmoving, infrastructure, and industrial projects. This model is highly regarded among construction companies due to its robust design, high component durability, and efficient hydraulic system. The key element of the machine is the six-cylinder Liebherr D936 A7 engine, which delivers approximately 190 kW of power and ensures a sufficient torque reserve when operating under heavy loads.

The machine offers excellent operational stability, a long working reach, and high breakout force, which translates into maximum efficiency during earthmoving and material handling operations.

Characteristics of the R 936 Model

The Liebherr R 936 was designed as a versatile crawler excavator to operate in the toughest terrain conditions. The solid crawler undercarriage ensures high stability during deep excavation and material handling operations. The boom and arm structure has been optimized for heavy loads, and the applied hydraulic solutions enable smooth and precise control of the attachments.

Thanks to its durable tracks and the possibility of mounting various attachments, the crawler excavator is commonly used for:

• earthworks and excavation tasks,
• road and transport infrastructure construction,
• demolition works,
• bulk material handling,
• industrial and energy sector investments.

Liebherr D936 A7 Engine – Approximately 190 kW of Power

The Liebherr D936 A7 power unit was developed for heavy-duty machinery requiring high reliability and stable performance for many hours a day. It is a large-displacement six-cylinder diesel engine characterized by high torque available even at low engine speeds.

The engine works perfectly with the machine's hydraulic system, ensuring adequate hydraulic pump performance even during simultaneous execution of multiple movements. Its high operating refinement and optimized fuel consumption make the D936 A7 unit highly valued by both operators and construction fleet owners.

These parameters enable efficient operation of the systems responsible for:

• working movement of the arm and boom,
• slewing of the superstructure,
• powering the main hydraulic pumps,
• travel and movement of the machine across the terrain.
