A 924 Litronic Liebherr Excavator Specs & Dimensions - (2014 - 2019)

Low Engine Speeds

Compared to the previous model, the engine speed has been reduced from 1,800 rpm to 1,700 rpm. The machine’s operating point has thus been optimised for outstanding fuel efficiency at maximum digging performance.

Low Noise Levels

The use of viscoelastic mounts, good insulation and low-noise diesel engines from Liebherr minimises noise emissions and vibrations. The noise levels are just 72 dB(A) in the operator’s cab and 103 dB(A) outside.

Operation and Displays

Large high-resolution operating unit, self-explanatory, colour display with touchscreen, video-compatible, numerous setting, control and monitoring options, e.g. air conditioning control, fuel consumption, machine and tool parameters.

Automatic Digging Brake

The automatic digging brake ensures that a manual actuation of the brake pedal is no longer required, thus leading to easier operation of the machine. If the machine is at a standstill, the digging brake is automatically applied. Furthermore, the automatic digging brake can be linked with the automatic swing axle lock.

Travel Drive

High traction for fast acceleration and powerful engine permit top speed on hills Reduces unproductive travel time between tasks and on the building site Faster on site – More productive

Detailed Solutions

The A 924 Litronic offers numerous detailed solutions for greater comfort and efficiency. For example, a choice of steering wheel: for regular civil engineering tasks, the thin steering wheel is recommended as it affords better visibility of the working area. The stabilizer blade does not have any lubrication points and is maintenance-free – no need for time-consuming lubrication.

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 while reducing fuel consumption by up to 5%. Another reason for the long change intervals is 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 but also extends the service life of pumps, valves, and hydraulic lines.

Ergonomic excellence – Superior cabin design for operator comfort and wellbeing

The modern Liebherr operator’s cab offers the best conditions for healthy, focussed and productive working. Standard features include an air-sprung operator seat with seat heating, automatic air conditioning and the ergonomically arranged control elements with touch screen indicating unit. An example of the extensive safety equipment is the roll-over protection system (ROPS) for the cab fitted as standard according to ISO 12117-2.

Operator Seats

The Standard, Comfort and Premium operator seat versions available have recognized orthopedic properties, and offer sitting comfort at the highest level. Even the standard operator seat offers an extensive range of features such as air suspension, seat heating, headrest, lumbar support and many more.

in addition to operator's seat standard: lockable horizontal suspension, automatic weight adjustment, adjustable suspension stiffness, pneumatic lumbar vertebrae support and passive seat climatisation with active coal.

High Swing Torque

The separate hydraulic pump in the closed slewing circuit only supplies hydraulic fluid to the swing mechanism. The maximum delivery volume is thus available at any time for turning the uppercarriage for fast and dynamic rotational movements.

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.

Lifting more

The intelligent structure of the uppercarriage and separate mounting of the hoist cylinders permits a significant lift capacity. That makes the A 924 Litronic the ideal machine for pipeline and trenching applications. The most powerful wheeled excavator in its class can effortlessly accomplish tasks such as lifting and moving precast concrete elements and pipes or pulling out shoring boxes.

Safety

Besides the performance and efficiency of a wheeled excavator, the safety of the operator and the machine must always be paramount. Numerous equipment features such as the standard pipe break protection on the lifting and stick cylinders, electronic height limitation, overload warning system, impact-resistant laminated safety glass, rollover protection system (ROPS) and an emergency exit through the rear window provide maximum safety in all operations.

Excellent All-round Vision

The large areas of glass and the rear and side area monitoring systems provide the operator with an excellent view of his working area and the zone around the machine. This perfect view enhances the operator’s safety and ensures that in turn he can handle the machine safely at all times.

Pipe Fracture Safety Valves

The standard pipe fracture safety valves on the stick and hoist cylinders prevents 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. This service includes 1 year of use free of charge as standard for the wheeled excavator A 924.

Exceptional Service and a Reliable Partnership

Liebherr 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

A fast response when service is required minimises downtime and ensures that schedules can be met. This is made possible by a spare part availability rate in excess of 98% and a 24 h delivery service for spare parts. Service engineers trained by Liebherr carry out service and maintenance work on the spot, quickly and in accordance with the manufacturer’s specifications.

Digging Force

High digging and breakout force in the field Continuously high digging performance even in tough ground More digging force for faster results

Lift Capacities

The lift capacities on the load lift hook of the Liebherr quick coupler SW48 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 based on the ISO 10567 standard 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. 12 t). Without the quick coupler, lift capacities will increase by up to 226 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.
