PR 724 LGP Liebherr PR 724 LGP Specifications & Technical Data (2004—2014)

Low service costs

The maintenance intervals are optimally specified for the individual components. Maintenance-free solutions are used in areas exposed to dirt. All the service points on the engine can be accessed from the same side. Also, the hydraulic tilting cab allows easy access to the hydraulic components. Service tasks can be performed quickly and efficiently.

Intelligent solutions for continuous operation

The electrically controlled hydrostatic fan regulates the operating temperature independently of the engine speed. This lowers fuel consumption and shortens the time it takes to warm up the engine. The extra-large cooler fins achieve an excellent self-cleaning effect. High-quality braided protection and a cleverly laid wiring harness prevent condensation from forming and provide lasting protection against mechanical damage.

Clever details

A large storage compartment with a 12 V socket for running a cooler is standard. The flexible, adjustable seat with three armrest positions provides a comfortable working position. Other details such as sliding windows, tinted glass, and foot rests further increase comfort.

High pushing power

The characteristics of the new Tier IIIA diesel engine are tuned to the high power required when pushing material and cornering. This provides smooth, powerful forward thrust in all situations. The hydrostatic travel drive requires no gearshifting, and the engine power is transmitted to the tracks without interruption – even while steering. This means the driver can comfortably control the travel speed.

Economy

Liebherr crawlers are always designed with economy in mind. The PR 724's low fuel consumption makes a decisive contribution towards reducing costs. Long-lasting components and time-saving maintenance greatly increase availability.

Low fuel consumption

The Liebherr diesel engine always runs at a steady speed in the most economical range – regardless of the travel speed. This ensures fuel-saving operation. The low piston speed greatly improves the filling of the cylinder chambers, which results in more efficient fuel combustion. The hydrostatic travel drive ensures maximum efficiency at all speeds, even when driving slowly and reducing power. This system makes sure that only the power actually required by the working hydraulics is consumed, and fuel is saved when the attachment is not in use.

Liebherr drive train

Liebherr diesel engines have been developed for the harshest operating conditions. The rigid ladder frame ensures stability, while the low rated speed guarantees reliability and long service life. The tried-and-tested hydrostatic travel drive does without components such as the torque converter, shifting gear, and differential steering or steering clutches. The standardised hydraulic pumps and motors operate practically without any wear. The large final drives in Generation 4 machines are extremely robust and designed for very high loads. The double seal with automatic leak monitoring offers reliable protection.

Excellent grading characteristics

The long, geometrically optimised undercarriage ensures smooth, extremely low-vibration travel characteristics. The main frame and oscillating bar are particularly resistant to buckling. The oscillating bar with its elastic bearing absorbs vibrations to allow optimum grading.

Robust steel construction

The main frame is of the tried-and-tested box-type design. This makes it extremely resistant to buckling and easily able to take up the forces applied to it. Parts subject to particular strain are made of cast steel.

Comfort

The generation 4 crawler tractors provide the driver with a generously sized workplace designed according to the latest ergonomic principles. The spacious deluxe cab offers an ideal view of the working area and equipment. The machine can be precisely and safely operated using the intuitive single-lever control. The redesigned cab stands out with its extraordinary driver comfort. Generously spacious, ergonomically designed and quiet, Liebherr cabs provide the ideal conditions for productive, non-tiring work. Excellent sightlines facilitate precise and safe operation.

De-luxe cab

The driver’s cab in Generation 4 Liebherr crawler tractors offers the ideal conditions for relaxed, focussed work. All the controls are clearly laid out within easy reach.

Simple and precise control

All the driving functions – including turning on the spot – can be comfortably and precisely controlled using a single lever.

Safety in every situation

The crawler tractor always keeps its traction, even when driving on slopes. The hydrostatic transmission allows the driver to control braking by simply pulling the joystick back toward the middle. A parking brake which is automatically activated when the machine is at a standstill provides additional safety.

Instrument panel

The instrument display is ideally positioned in the driver’s field of view. Automatic monitoring, indication and warning of unusual conditions during operation.

Versatile in use

Another strength of the hydrostatic travel drive becomes apparent when operating in confined spaces. All steering movements can be performed quickly and powerfully – right up to turning on the spot. The clever arrangement of the drive components allows quick and safe work, even on slopes and banks. The PR 724 has sufficient ground clearance to operate on the heaviest soil and roughest terrain. Many different blade types, rear attachments and undercarriage configurations are available, which means the PR 724 can be ideally configured for its intended use.
