A 918 Litronic Liebherr Excavator Specs & Dimensions - (2016 - 2019)

High Performance

The intelligent structure of the uppercarriage and separate mounting of the hoist cylinders permits a significant lift capacity. Close to the machine, the A 918 Litronic even exceeds the lift capacity level of the next higher machine category, which means it offers more performance reserves for those more demanding jobs.

Work Speed

The speed of the machine can be easily adapted to the different applications using the MODE switch. The wheeled excavator also permits a high work speed with overlapping equipment movements. Excavation, backfilling and profiling tasks can thus be completed quicker.

Working with Precision

The standard joysticks with proportional controls and also the extraordinary sensitivity of the hydraulic system enable precision work at high speeds and parallel movements. This means the machine operator can carry out the most challenging tasks in a short time, not only at reduced speed but also with maximum performance output from the machine.

Detailed Solutions

Numerous details provide greater comfort and efficiency. For example, there is a choice of two different steering wheel versions. The thin steering wheel is recommended for regular civil engineering work as it affords better visibility of the working area. Also, the stabiliser blade does not have any lubrication points and is maintenance-free. No need for time-consuming lubrication.

Exceptional Service and a Reliable Partnership

Liebherr compact wheeled excavators are not only powerful, robust, precise and efficient, they also impress with the service-orientated machine design. Maintenance is performed quickly, simply and safely. This reduces maintenance costs and keeps machine downtimes to a minimum.

Service-based Machine Design

The service-based machine design guarantees short servicing times, thus minimising maintenance costs due to the time it saves. All the maintenance points are easily accessible from the ground and easy to reach due to the large, wide-opening service doors. The enhanced service concept places the maintenance points close to each other and reduces their number to a minimum. This means that service work can be completed even more quickly and efficiently.

Engine Idling and Engine Shut-down

The standard automatic idling function reduces the engine speed to idle as soon as the operator takes his hand from the joystick so that no hydraulic function is activated. Proximity sensors in the joystick levers restore the original engine speed as soon as the operator’s hand is moved towards the lever again. This ensures that the set engine speed is available immediately. The result is a combination of fuel saving and reduced noise levels. Operating costs can be reduced even further with the optional automatic engine shut-down function.

Low Noise Levels

The use of viscoelastic mounts, good insulation and low-noise diesel engines from Liebherr minimises noise emissions and vibrations.

Diesel Engine

A compact cooling system consists of a cooling unit for water, hydraulic oil, and charge air with a stepless thermostatically controlled fan. Additionally, it includes fans for radiator cleaning and can be completely folded away.

Automatic Digging Brake

The automatic digging brake ensures that manual actuation of the brake pedal is no longer required, thus leading to easier operation of the machine. When the accelerator pedal is in a neutral position and the machine is stationary, the digging brake engages automatically. This results in faster work processes and enhanced safety for man and machine, particularly during operation with frequent relocation of the excavator. Furthermore, the automatic digging brake can be linked with the automatic swing axle lock. When the machine is deployed and working, the swing axle locks automatically and thereby provides optimum stability.

Liebherr Working Tools and LIKUFIX

To boost the productivity of its construction machines, Liebherr offers a broad range of working tools for different fields of application. Furthermore, the hydraulic excavators can also be equipped with the Liebherr LIKUFIX hydraulic quick coupling system. The combination of a hydraulic Liebherr quick coupling system with the LIKUFIX coupling block permits fast safe changing of mechanical and hydraulic working tools from the operator’s cabin. This boosts productivity on average by 30 %.

Hydraulic Oils with Added Value

Liebherr hydraulic oils achieve a service life of 6,000 operating hours plus. Instead of having defined change intervals, the results of the oil analysis (every 1,000 operating hours or after one year) determine when the oil needs to be changed. The unique Liebherr Hydraulic Plus oil can even achieve a service life of 8,000 operating hours plus at the same time as reducing fuel consumption by up to 5%. Another reason for the long change intervals is also the comparatively large hydraulic tank capacity, which enables a long oil setting time. Enclosed air molecules can escape upwards and are not sucked in again. This not only protects the hydraulic oil, it also extends the service life of pumps, valves and hydraulic lines.

Ergonomic Excellence

The modern Liebherr cab with a standard air-suspension heated driver’s seat and automatic air-conditioning ensures a pleasant atmosphere, thus offering the best conditions for healthy and productive work whilst allowing the driver to work with full concentration. The ergonomic control elements with touchscreen display also simplify the operation of the wheeled excavator. The extensive safety equipment includes the rollover protection system (ROPS) for the cab fitted as standard according to ISO 12117-2.

Radio with Hands-free Device

The radio can be equipped with an MP3-compatible USB slot and integrated hands-free device, which means that calls can even be taken while working with the machine. Operation of the radio is by means of the touchscreen colour display. Station search, volume control and mute can be controlled with ease. Simple operation for greater comfort.

Joystick with Proportional Control

The 4-way mini-joysticks permit the operation of the support jib, the tool attachment/implement, as well as the steering of the machine, without manual intervention. There are two buttons and a rocker switch installed on each joystick. They also increase the number of functions. The slim, ergonomic design rounds off the operating concept.

Operator's Cab

ROPS safety cab structure (roll-over protection system) with individual windscreen or featuring a slide-in sunpart under the ceiling, work headlights integrated in the ceiling, a door with a sliding window (can be opened on both sides), large stowing and depositing possibilities, shock-absorbing suspension, sound-damping insulating, tinted laminated safety glass, separate window shades for the sunroof window and windscreen.

Operator's Seat

The operator's seat is air cushioned and features 3D-adjustable armrests, a headrest, a lap belt, a seat heater, manual weight adjustment, adjustable seat cushion inclination and length, and mechanical lumbar vertebrae support. In addition, the comfort option includes a lockable horizontal suspension, automatic weight adjustment, adjustable suspension stiffness, pneumatic lumbar vertebra support, and passive seat climatisation with an active coal ventilator.

Operation and Displays

The large high-resolution operating unit features a self-explanatory, colour display with touchscreen capabilities, video compatibility, and numerous settings, control, and monitoring options, such as air conditioning control, fuel consumption, machine tool, and parameters.

Automatic Air Conditioning

The automatic air conditioning offers convincingly intuitive operation. Temperature, blower setting and the various air nozzles in the head, chest and foot areas are set using the touch screen on the indicating unit. The defrost/defog one-button function clears fogged up windows in the shortest possible time. The filter for the cab air can be changed easily and conveniently from the outside.

Air-conditioning

fast de-icing and demisting at the press of a button, air vents can be operated via a menu; recirculated air and fresh air filters can be easily replaced and are accessible from the outside; heating-cooling unit, designed for extreme outside temperatures, sensors for solar radiation, inside and outside temperatures (country-dependent).

Pipe Fracture Safety Valves

The standard pipe fracture safety valves on the stick and hoist cylinders prevent the attachments from dropping in an unregulated way and ensure maximum safety during every operation.

Efficient Management

LiDAT, Liebherr’s own data transmission and positioning system, facilitates efficient management, monitoring and control of the entire fleet in terms of machinery data recording, data analysis, fleet management and service. All of the important machinery data can be viewed at any time on a web browser. LiDAT provides you comprehensive work deployment documentation, greater availability thanks to shorter downtimes, faster support from the manufacturer, quicker detection of strain/overload and subsequently a longer service life of the machine as well as greater planning efficiency.

Robust Design

All steel components are designed and manufactured by Liebherr itself. High-strength steel plates configured for the toughest of requirements result in high torsional stiffness and optimum absorption of forces induced for a longer service life.

Digging Envelope

The digging envelope with quick coupler includes stick length, max digging depth, max reach at ground level, max dumping height, max teeth height, and min attachment radius. These parameters are crucial for understanding the operational capabilities of the backhoe bucket.

Operating Weight

The operating weight includes the basic machine with 8 tyres plus intermediate rings, two-piece boom 5.25 m, stick 2.45 m, quick coupler SW33 and bucket 1,050 mm/0.80 m³. This weight is essential for transport and operational planning.

Lift Capacities

The lift capacities on the load lift hook of the Liebherr quick coupler SW33 without working tool are stated in metric tons (t) and are valid on a firm, level supporting surface with blocked oscillating axle. These capacities can be slewed through 360° with the undercarriage in the transverse position. Capacities in the longitudinal position of the undercarriage (+/– 15°) are specified over the steering axle with the stabilizers raised and over the rigid axle with the stabilizers down. The values apply when the adjusting cylinder is in the optimal position. Indicated loads are based on the ISO 10567 standard and do not exceed 75% of tipping or 87% of hydraulic capacity, or are limited by the permissible load of the load lift hook on the quick coupler (max. 5 t). Without the quick coupler, lift capacities will increase by up to 110 kg. In accordance with the harmonised European Standard EN 474-5, hydraulic excavators used for lifting operations must be equipped with pipe fracture safety valves, an overload warning device, a load lift hook, and a lift capacity chart.
