R 936 Liebherr excavator specs & Dimensions (2012 - 2016)

High stability undercarriage

The undercarriage concept leads to increased performance with improved service life. Thanks to the connection of the middle section being extended as far as the ends of the chassis beams, known as the X-design, the forces are better distributed, which increases the service life of the undercarriage.

Minimal noise and vibration

The new cab on the Liebherr crawler excavator meets the standards for noise emissions and whole-body vibrations, which makes work a pleasure.

Power and speed

The R 936 achieves particularly fast work cycles, thanks, for example, to the powerful slewing drive of the superstructure, the rapid slewing rates, and the creation of high slewing torque.

Economic use around the clock

The Liebherr engine delivers full power even at low speeds. It is equipped with direct injection, turbocharger and intercooling and has an excellent torque characteristic with high power reserves. Fuel consumption and emission levels can be reduced thanks to this selectable feature: when the excavator is not moving or in operation, the engine speed is automatically reduced to idle. Safe, non-slip steps and ergonomically positioned handles ensure safe access to all maintenance parts. All necessary maintenance work can be carried out quickly and cost-effectively thanks to the clever design.

Top technology for maximum profitability

This regulating system causes an efficient conversion of the engine output in hydraulic performance – which results in better utilization of the available engine power. The result: higher digging forces, shorter cycle times and lower fuel consumption. A unique range of digging tools and quick coupler modules guarantee an economical advantage for jobs with frequent tool changes. Based on years and years of field experience, all components of the Liebherr Tool-Management System originate from its own research and production.

Features

Engine hood with lift help, extended tool kit, handrails with non-slip surfaces, Liebherr full-automatic central lubrication system (except connecting link for bucket kinematics), lockable tool box, maintenance-free swing brake lock, and sound insulation.

Engine specifications

After-cooled Common-Rail system injection, conforming with stage IIIB/Tier 4i emission standard, fuel filter and water separator, Liebherr particle filter, sensor-controlled automatic engine idling, and turbo charger.

Performance

Thanks to its innovative Advanced excavator system technology, the R 936 crawler excavator has performance features that are truly unique. Characteristic elements of this system technology include the particularly effective and energy-efficient Positive Control twin-circuit hydraulic system, which was specifically designed for machines with a high level of superimposed functions and operational movements. The electronic pump control arrangement sets this technology apart, creating a new standard for performance and quantity control that entirely matches the operator’s needs.

Economy

Crawler excavators from Liebherr guarantee maximum productivity. The optimum interplay of hydraulics and electronics means that individual movements and superimposed movements alike can be carried out particularly efficiently. And, perhaps last but by no means least, the perfect harmonisation of all the components means that energy expenditure during operation can be kept to an absolute minimum.

Technology with perspective

The at-a-glance layout of the hydraulic, lubrication, and electricity lines makes for optimum functional reliability and maximum availability of the unit. Best possible corrosion protection is guaranteed thanks to components and modules being finalpainted and surface treated before assembly.

Perfect optimisation

Individual components of the drive train, manufactured in-house, such as diesel engine, traction drive, rotary actuators, operating pump and hydraulic cylinder are perfectly optimised with one another. As components of a total system designed for long operational life, they guarantee maximum possible reliability.

Integrated excavator system technology

Among the high-tech equipment on the Advanced version of the R 936 is the newly-developed integrated excavator system technology. This is based on the Positive Control hydraulic system, controlled by Liebherr electronics and the system software. The sensors located at strategic points on the machine form the basis for an intelligent system that allows for fast and fluent working.

Positive Control twin-circuit hydraulic system

When travelling straight or in a curve, and during levelling work, the two pump circuits of the hydraulic system are separated or grouped together, as the need arises. Separation of the systems means that different consuming components can be supplied with different load pressures independently, and saving energy too. By contrast, grouping the pump circuits allows for maximum speeds with individual or superimposed movements, and that means optimum energy utilisation.

Hydraulic Features

Filter with integrated fine filter area, hydraulic tank shut-off valve and pumps, Liebherr hydraulic oil, pressure storage for controlled lowering of equipment with engine turned off, and pressure test ports for hydraulic. Additionally, there is a stepless work mode selector.

Standard Equipment

Lashing eyelets Lifetime-lubricated track rollers Sprocket with dirt ejector Track guide at each track frame (one piece) Tracks sealed and greased.

Individual Options

Reinforced base panel for centre section Reinforced cover plate and base plate for centre section Straight track guide Tool box Track guide at each track frame (four pieces) Track guide at each track frame (three pieces).

Comfort

In the cab the driver can look forward to a workplace designed in accordance with the very latest findings in ergonomic science, with emphasis on comfort and ease of operation. The optimised arrangement of the hydraulic hoses means that the driver has an even wider field of vision, and the heating and climate control system fitted as standard means pleasant working conditions inside, whatever the weather. Liebherr crawler excavators are also particularly easy to service – maintenance tasks can be carried out easily and rapidly at readily accessible service points.

Safe work – with a clear layout

The entirely new design of the cab provides plenty of room, and creates a pleasant sense of space. Cab windows in the front, the roof, and on the right are made of break-resistant two-pane safety glass. The front windscreen is a two-part design and can be completely retracted. The cab meets ROPS requirements, providing the driver with even more protection.

Wide camera field of vision

The reversing camera for the R 936, fitted as standard, provides a wide-ranging view of the area behind the machine.

Fully automatic climate control system

The climate control system has more than 12 adjustable nozzles for individual control of air flow, and can be operated via the display.

Safety of functionality

The cab is equipped with an integrated roll-over protection system (ROPS) in accordance with ISO 12117-2, guaranteeing driver safety in any situation.

Automatic control of functionality

The operator can entirely focus on his job, because the integrated on-board electronic continuously performs a comparison with pre-determined target data. Eventual deviations from the target parameters are shown on the display.
