Liebherr Mining Equipment Colmar will launch its B-versions of the R9100 and R9150 hydraulic excavators in January 2019. The Liebherr R9100 and R9150 were launched in 2010 and 2012, respectively. The upgraded B-versions, the R9100 B and R9150 B are equipped with the Liebherr V12 diesel engine specifically designed to withstand extreme outside temperatures and high altitudes with low atmospheric pressure. Integrating the latest engine management system, these machines are built for extreme conditions.
The Liebherr D9512 diesel engine is the latest generation of Liebherr diesel engines and is now USA/EPA Tier 4f compliant. It has been upgraded on many levels with an increased engine lifetime (SMU target of 15,000 hours) and new features that facilitate and improve the engine maintenance.
Furthermore, the new B-versions come with the exclusive EVO Bucket Solution with patented Liebherr design to maximize the loading capacity and ensure optimal penetration efficiency. Contoured sidewalls and augmented depth provide the EVO Bucket backhoe bucket with a capacity of 7.5 m³ for the R 9100 B and 8.8–9.6 m³ for the R 9150 B (for a material density of 1.8t/ m³. The new buckets also make both the excavators a match the Liebherr T 236 truck and all other articulated and rigid trucks in the 50–100 t class.
The R 9100 B’s and R 9150 B’s upper structure is accessible via a fixed ladder or 45° access stair in option and integrates one large central platform equipped with slip resistant surfaces. This new arrangement with wide catwalks facilitates maintenance and ensures comfort during all the operations. These excavators are fitted with ergonomic access for fast and safe maintenance. All service points are within reach from one side and at machine level.
The modern and large cab provides optimal operator comfort. Mounted on silent blocks, the optimized cab design reduces vibrations. The new headliner limits noise pollution to provide a quiet working environment: decrease of 2 dB in the cab compared to previous versions.
The new B-versions are serially equipped with GSM data transmission functionalities to collect operating parameters, error codes and machine faults. The data is accessible through the Liebherr-Mining Data platform (LMD) on which the user can generate customized reports to track and analyse machine data.
The information collected through the Connectivity Kit is recorded in a worldwide database and enters a systematic assessment and resolution process to continuously improve existing and new products and components.
During the development of the B-series, several of genuine Liebherr components like the swing pump, went through an upgrade themselves to provide optimal reliability, superior productivity and a longer service life.
