Using Liebherr excavators, machine operators achieve impressive levels of performance, day-in and day-out. Whether in classic earthmoving, in roadway construction or for digging trenches and laying pipes: more can be achieved faster with Liebherr wheeled excavators. Power, speed and precision Lifting more Being faster Working with precision The intelligent structure of the uppercarriage and separate mounting of the hoist cylinders permits a significant lift capacity. Close the to machine, the A 914 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. The A 914 Litronic enables a high working speed, even when movements of attachment are performed in parallel. Excavating, backfilling and profiling tasks can be completed faster, new tasks can be started sooner. The speed of the machine can by adjusted easily using the MODE switch for load lifting work or grading work. The exceptional sensitivity of the hydraulic system allows precise working at high speeds, and with movements in parallel. 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. Digging force High digging and breakout force in the field. For continuously high digging performance even in tough ground. More digging force for faster results. Joystick steering The optional joystick steering function enables the operator to steer the wheeled excavator using the mini-joystick. Working and travelling movements can be executed simultaneously without having to move hands. More efficient operation for greater productivity. A 914 Litronic Bright and durable The LED rear lights fitted as standard not only look good, they also have a high brightness level and an extremely long service life. The LED front outline marker fitted as standard make it easier to see the machine on the road, and thus provides greater safety. 6 A 914 Litronic Reliability Reliability offers safety. Safety that significantly influences the success of a project. Whatever the weather, Liebherr stands for safety - with reliable construction machines and customer-oriented sales and service partners. This means a Liebherr construction machine is exactly what it should be: an investment that pays off. Durability and innovation Quality Expertise Service Key components such as diesel engine, hydraulic components, electronic components, swing ring and swing drive are developed, tested and produced by Liebherr itself. The significant depth of production ensures the highest quality and permits optimum coordination of components. The highquality Liebherr components are also used in many other sectors and products. Liebherr has been developing and producing hydraulic excavators for more than 6 years. This experience and the feedback from customers, sales and service form the basis for putting innovative ideas into practice. The result: wheeled excavators with excellent quality and reliability. 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. * subject to location More rear visibility - and to the side too The standard camera for rear-view monitoring is integrated in a protected location in the counterweight. Optional camera for the right side area, for greater safety on the site. Greater visibility for more safety. Maintenance without draining oil Standard shut-off valve for disconnecting the oil tank from the hydraulic system. For simple maintenance work on the hydraulic components without draining the hydraulic oil. Reduced maintenance time for higher machine availability. A 914 Litronic 7 Refuelling Using the optional refuelling pump, the machine can be refuelled directly from a fuel container. Remote cable operation and automatic shut off when the tank is full, for greater convenience and shorter refuelling times. Topping up. Simple, quick and safe. 8 A 914 Litronic Comfort The modern Liebherr operator s cab offers the best preconditions for healthy, concentrated and productive working. The features which make this possible include the standard feature of an air-sprung operator seat with seat heating, the automatic air conditioning and the ergonomically arranged control elements with touch screen indicating unit. One example of the extensive safety equipment is the roll-over protection system (ROPS) for the cab fitted as standard according to ISO An advance in comfort and convenience Automatic air conditioning Operator seats Detailed solutions 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. The Standard, Comfort and Premium operator seat versions that are available have recognized orthopedic properties, and offer sitting comfort at the highest level. Even the standard operator seat offers an extensive range of standard features such as air suspension, seat heating, headrest, lumbar support and many more besides. The A 914 Litronic offers numerous detailed solutions for greater comfort and efficiency. For example, two different steering wheel versions can be selected: for regular civil engineering tasks, for example, it is recommended to have the thin steering wheel since it affords better visibility of the working area. Also, the stabilizer blade does not have any lubrication points and is maintenance-free. No need for time-consuming lubrication. Convenient radio operation Optional radio with MP3-capable CD player and front aux-in for connecting external playback devices.
