In June 2015, Liebherr Brasil Ltda. Launched the R 954 C SME 60 t crawler excavator. The excavators are already in operation and are providing excellent production figures, with four machines operating in high-production quarries in the region of Sao Paulo.
The first two R 954 C SME excavators, manufactured by Liebherr Brasil in Guaratinguetá (SP), were delivered to Riuma quarry, located in the region of Jaraguá (SP). Operational since July and August 2015, the machines have performed better than expected. The quarry, which is 50 years old, mainly produces aggregates for civil construction at a capacity of 800 tph. The new Liebherr 60 t crawler excavators fulfilled their mission of improving the cost/production ratio of the quarry.
According to Riuma Quarry, the excellent build quality of the Liebherr R 954 C SME crawler excavators is fully suitable to the operation: “One of the biggest challenges of the new machines is that of excelling the other equipment on site, and, from what we were able to assess to date, the production/consumption ratio is very good and the availability of the machine is great”, affirms Roberto Iudice, owner and partner of Riuma.
The new 60-tonnes excavator is equipped with an S-HD (Super Heavy Duty) undercarriage, D8K chains, same as the Liebherr R 964C / R 966 crawler excavators, 600mm standard track pads with dual clamps, bi-supported overhead rollers, drive train with dual teeth and belt guide. With 10 tonnes less than the next class of Liebherr excavators, the 70-tonnes, this machine has faster operational cycles – which when combined with the lower fuel consumption – will generate a better cost/production ratio. At the operation of Riuma, the 40-tonnes trucks are loaded on average with eight cycles. According to the quarry, the fill rate of the trucks is substantially higher than the rate obtained with other equipment, due to the excellent dimensions of implement and buckets.
Regarding the analysis of results, Riuma follows a very systematic process involving complete studies of costs, production, comparisons with other machines operating at the site and also after-sale service.
Basalto Quarry is also pleased with the results presented by the R 954 C SME operating since November of 2015 at the quarry located in Itapecerica da Serra, São Paulo. According to Mr. Darcy Braga, director of the quarry, Liebherr’s abilitly to supply the machine within the timeframe required along with the competitive pricing and the excellent after-sales service history provided by Liebherr to the quarries existing machines were their reasons for purchasing these new crawler excavators. “The R 954 C SME machines have more than met our requirements. They are robust and the availability is very good. The performance of the machines has increased productivity”, says Mr. Darcy.
The newest R 954 C SME crawler excavator produced at the Liebherr facility in Guaratinguetá (São Paulo) was delivered in November to Geocal, another large quarry established in the region of Santana do Parnaíba, also in the metropolitan region of São Paulo. With a high monthly production of limestone and gravel, the quarry relies on a fleet almost completely composed of Liebherr equipment.
