AMM boosts efficiency with new Liebherr PR 776 crawler dozers

The AMM construction company (Murcia, Spain) specialises in civil engineering and major construction projects, covering a range of services, spanning railway construction, hydraulic engineering and industrial projects. With a significant commitment to industrial and agricultural transformation, AMM contributes to the development of sustainable infrastructure in Spain. The two new Liebherr PR 776 Crawler Dozers compliment the existing fleet, which includes a PR 744, PR 746, PR 764 and PR 766, ensuring the company is well equipped for major construction projects.

The impressive efficiency of Liebherr Crawler Dozers Rising energy prices and stricter environmental standards are a constant feature of modern times, where fuel efficiency plays a critical role. And the decisive advantages of the PR 776 where recently reported by one of AMM?s experienced machine operators. For more than two decades, he has exclusively operated dozers from other leading manufacturers - that is till now: He has been so impressed with the high efficiency and power output of the Liebherr Crawler Dozers, he has become a full convert and outspoken Liebherr fan. The PR 776 is noted for optimum efficiency and power transfer, making construction operations not just more efficient, but also more sustainable. With an impressive average fuel consumption of 55 litres per operating hour, the Liebherr model sets new class leading standards. AMM's experienced operator was quick to emphasise how the Liebherr machine shows significantly different performance in terms of fuel consumption compared to alternative dozers, such as the models from one of the well-known manufacturers in this class. From the operator's own experience, the average fuel consumption on these machines was up to 90 litres per hour.

PR 776: Power pack for material quarry extraction and renaturalisation The first of the new Liebherr PR 776 Crawler Dozers has already completed 1,200 operating hours in a quarry near Murcia, Spain. Here, it has been used primarily for material extraction for railway construction, with the machine being used equally for pushing and ripping operations. In the quarry, the efficiency and power output of the PR 776 really stand out. With maximum power output for pushing and pulling, it is ideal for transporting large quantities of rock. The hydrostatic drive ensures stepless speed adjustment and continuous power transmission, even in difficult terrain. This enables precise and effective movement of material - ideal for use in quarries - while the Eco mode makes operation even more efficient.

The second PR 776 is being used for restoration of an expired quarry near Ciudad Real, Spain. The renaturalisation of quarries is critical for minimising environmental impact of mining work and returning the terrain to a near-natural state. The PR 776 offers significant advantages in this application: The precision and mobility of the hydrostatic drive provide the driver with optimum support when modelling the terrain and filling in excavated pits.
