Fuel efficiency
Load-sensing Hydraulic System
Keestrack have been pioneering the use of load-sensing hydraulic systems for many years. The hydraulics monitor feed load and automatically adjust to the requirements of the load. As a result, 4-6 liters of fuel can be saved per hour, and when applied to typical operation of 1,500 hours, this equates to a saving of up to 7,500 litres.
The load-sensing systems provide cost savings of approx. 30% compared to crushers and screeners, offered by other manufacturers, who do not apply this technology.
Hybrid diesel / electric drive options
Keestrack introduced the first hybrid classifier C6 in 2012 and has been continuing this path ever since as we believe this is not just an added value for the environment but it is also a significant improvement on the cost efficiency of our machines.
Keestrack delivers several optional drive systems with plug in and plug out options. The performance and end results are identical to the standard diesel/hydraulic driven machines but energy costs, maintenance costs and cost of ownership are significantly lower. With the hybrid drive system savings up to 50% can be achieved, with the plug in electric option the savings are even up to 70%.
Fuel & energy consumption for C6 Classifier
Diesel/hydraulic
Diesel/hydraulic model with standard load-sensing hydraulic system consumes approximately 14 litres an hour.
Electric drive via onboard Genset
Electric drive via onboard Genset powered by a C6 diesel engine consumes approximately 9 liters an hour.
This results in fuel savings of approximately 33% when compared to a C6 with diesel/hydraulic drive.
And when compared with other classifierson the market (who do not use load sensing hydraulic systems) fuel savings can even rise to over 50%.
Plugged into crusher
Connected to a crusher results in a fuel consumption of 4 litres more of the crusher total consumption.
Electric drive via electrical mains
Connected directly to the mains supply energy savings can be approximately 70% when compared to a diesel/hydraulic model.
And when compared with other classifiers on the market (who do not use load sensing hydraulic systems) fuel savings can even rise to nearly 80%.
