Acerca de · Liebherr R944Resumen
The Liebherr R944 is a large hydraulic crawler excavator in the 40-tonne class, offering an operating weight of 39,800 kg and an engine output of 258 hp. It is positioned in the upper tier of the general-purpose large excavator segment, where it competes on digging force, hydraulic performance, and structural durability. With a standard bucket capacity of 1.8 m3, the machine is built for high-volume earthmoving and demanding civil engineering cycles. Liebherr's in-house engineering approach, covering both the hydraulic system and the upperstructure, is a defining characteristic of the R944 product line.
Aplicaciones típicasDónde se utiliza esta máquina
The R944 is suited to large-scale earthmoving, bulk excavation on civil infrastructure projects, and deep foundation preparation where consistent bucket fill rates are required. In quarrying and mining support roles, the 40-tonne class provides the reach and breakout force necessary to load articulated dump trucks efficiently. Port and industrial site operations also deploy machines of this class for heavy material handling when paired with appropriate attachments.
Inspección del mercado de segunda manoQué hay que comprobar antes de comprar
Before committing to an R944, commission a full hydraulic pressure test across all functions, including slewing, boom, arm, and bucket circuits, as pressure loss in Liebherr's proprietary system can indicate wear in the main control valve or pump assemblies. Inspect the undercarriage thoroughly, including track links, rollers, idlers, and sprocket teeth, as replacement of a full undercarriage kit on a 40-tonne machine represents a significant cost commitment. Review all available service records and confirm that hydraulic oil and filter changes have been carried out at manufacturer-specified intervals, since contaminated hydraulic fluid is a leading cause of premature component wear in this class. Check the slewing ring for play and uneven wear patterns, and inspect the boom and arm for cracks at high-stress weld points. Where possible, request a live machine demonstration under load to verify that all hydraulic functions respond within normal cycle times.

Within the 40-tonne crawler excavator segment, the R944 is cross-shopped primarily against the Hitachi ZX400 and the Caterpillar 340. The Caterpillar 340 is closely matched on operating weight and power, and buyers typically compare the two on dealer support network density and parts availability in their region. The Hitachi ZX400 appeals to operators who prioritise hydraulic system responsiveness and Hitachi's established track record in high-cycle earthmoving. The Liebherr R944 differentiates itself through its fully proprietary powertrain and hydraulic integration, which some fleet managers value for consistency of performance across variable load conditions. Within the price band for any of these models, the principal attributes that drive position are recorded operating hours, maintenance history and service documentation, configuration type such as standard boom versus long-reach, installed attachments including quick-coupler systems and additional piping, undercarriage wear condition, and overall structural and cosmetic condition of the upperstructure and slewing ring.
