At Intermat, Liebherr showcased the ideal machine for construction sites with space restrictions with the A 914 Compact Litronic wheeled excavator. Its operating weight is between 15,200 and 17,500 kg. The machine impresses with its productivity and high level of flexibility, especially in urban zones. The wheeled excavator complies with the requirements of the Stage IV/Tier 4 Final exhaust emissions standard.
The exhibit at Intermat was equipped with a 2,550 mm wide undercarriage with rear outriggers and front stabilizer blade. The equipment is made up of a 4.90 m long offset two-piece boom, a 2.45 m stick and the Liebherr quick coupling system LIKUFIX.
The compact Liebherr wheeled excavator shows how practical and diverse it is in daily operation: Some of the biggest challenges for machine operators in urban areas are the space restrictions on construction sites. With the short tail swing of only 1.75 m, the A 914 Compact can be used flexibly in traditional excavation work, uncovering existing structural elements, modelling banks, compressing materials, as well as all other earthworks.
Powerful and efficient
The requirements of the Stage IV exhaust emissions standard are satisfied in the A 914 Compact with the combination of a diesel oxidation catalyst and a SCR system. Despite the significant reduction of the emissions to help protect the environment, Liebherr managed to increase the engine power by 10 kW: With the 105 kW/143 hp engine the machine achieves a higher performance and driving distance with high fuel efficiency at the same time. The quick removal of material also in hard soil and the shorter travel times lead to maximum productivity and ultimately to a reduction in operating costs. As the engine already reaches its maximum output at low speeds, the components are protected, thus ensuring a long service life.
Thanks to the innovative Liebherr Power Efficiency (LPE), which optimally controls all the new Liebherr wheeled excavators' power management processes, fuel consumption is considerably reduced. The proactive intervention in the engine control, the adjustment of the swing angle of the hydraulic pump and the adaptation of the engine speed, result in optimum efficiency of the drive components in every work situation.
Safe and comfortable at the same time
With the largest cab in its machine class, the A 914 Compact also offers a comfortable environment for the machine operator to work productively and with maximum concentration. A foldable armrest which provides the machine operator with enhanced safety when getting in and out of the excavator is included in the standard equipment. The standard rear-view and lateral cameras also increase safety on the construction site, as they give the machine operator an optimal view at all times.
The simple and intuitive operation further facilitates day-to-day operations. The operation of the excavator's support jib via the joystick's proportional controls offers greater comfort. When moving the machine the operator does not need to change grip and is able to complete levelling work with dexterity and precision. With the standard automatic working brake, the service brake is opened automatically upon start up and closes again automatically when the accelerator pedal is released. This ensures maximum safety and high productivity owing to shorter response times.
Optimal service accessibility
The large engine hood in the A 914 Compact opens along the entire right side of the machine to give quick, convenient access to all servicing points. Daily routine maintenance can therefore be carried out from ground level. To simplify the cleaning of the radiator, which is of generous size, the powerful cooling fan is simply folded out to the front. To ensure that the hydraulic oil can be used for an extended period without contamination by metal particles, there is a magnetic rod in the hydraulic oil tank to trap them; it can easily be cleaned when necessary.
Higher productivity with LIKUFIX
With the optional fully-automatic LIKUFIX quick coupler system, only a few seconds are needed to detach or attach mechanical and hydraulic tool attachments and implements, without having to leave the operator's cab. In combination with Liebherr’s successful range of tool attachments and implements, for example "Productive" buckets, productivity gains as high as 30% can be achieved.
