Powerful and robust: Liebherr crawler tractors are built for longevity in terms of design and choice of materials.
Liebherr diesel engine • The electronically modelled power and torque characteristics offer excellent traction for pushing and ripping. • Extra-deep oil pan allows operations at up to 45° incline. • Designed specifically for construction equipment – provides a long service life and operational reliability. 4 PR 724 Litronic PR 724_enUS_12_12.indd 4 04.12.
Performance Liebherr has been successfully building hydrostatically driven crawler machines for more than 30 years. The powerful latest-generation PR 724 is the ideal machine for many different applications. Excellent grading characteristics Long running gear The long, geometrically optimized undercarriage ensures smooth, extremely low-vibration travel characteristics. High-strength main frame construction The main frame and oscillating bar are particularly resistant to buckling.
Low fuel consumption thanks to steady engine speed Specific fuel consumption [g/kWh] • The rated engine speed falls within the rpm range where specific fuel consumption is lowest. The result is maximum fuel economy without sacrificing power. Rated engine speed [1/min] 6 PR 724 Litronic PR 724_enUS_12_12.indd 6 04.12.
Economy Liebherr crawlers are always designed with economy in mind. The PR 724’s low fuel consumption contributes directly to reducing costs. Long-lasting components and time-saving maintenance greatly increase availability. Low fuel consumption Steady, low engine speed The Liebherr diesel engine runs at a steady speed in the most economical range – regardless of the travel speed. This ensures fuel-saving operation.
Key technologies developed by Liebherr • Liebherr has decades of experience in developing, designing and manufacturing components. • Key components such as engines, transfer gears, hydraulic components and final drives are manufactured in-house assuring the highest degree of quality. 8 PR 724 Litronic PR 724_enUS_12_12.indd 8 04.12.
Reliability The high quality and established technology of the PR 724 make it a machine of the highest reliability. Specially developed components for use in construction machinery and durable cast steel parts at points under heavy stress guarantee stability even in the most demanding situations. Liebherr drive train Liebherr engine Liebherr diesel engines have been developed for the harshest operating conditions.
Intuitive single joystick control Inch/brake pedal • Precise control ranges: Three travel speeds can be preselected and individually programmed using the joystick buttons. Default settings: Level 1: 0 – 2.5 mph Level 2: 0 – 4.0 mph Level 3: 0 – 6.8 mph • In addition to the travel joystick, the operator can use the foot pedal to control the speed and activate the braking function as required.
Comfort The redesigned workplace offers the operator a remarkable degree of comfort. Spacious, quiet and designed with ergonomics in mind, Liebherr comfort cabs offer the ideal conditions for fatigue-free, concentrated work. Excellent visibility facilitates safe and precise operation. A top-class cab Ergonomics The ergonomically-designed operator’s cab offers the ideal environment for relaxed, productive work. All instruments and operating controls are laid out comprehensibly and within easy reach.
