Keestrack’s track-mounted impact crusher units comprises three models, starting with the compact R3, which is proving itself on the market as a highly flexible 30-ton “construction-site crusher.”
Keestrack’s top-range R6 flagship model has a total weight of 60 tons when fully equipped and remains the most prominent machine among the 1300-impactors for recycling, large-scale projects, and quarrying applications. Thanks to the license-exempt dolly transport it readily competes with the much heavier competition within the 450-tph performance class.
Moreover, the large-scale “Destroyer” unit has been available for several years as an R6e model in a diesel-electric hybrid version with electric motors driving the conveyor belts and screen components. Since 2014, the Keestrack R6e has been available with a 250-kW electric motor for the crusher and an electric 110-kW drive for the on-board hydraulic system, and optionally also the all-electric plug-in operation from the mains.
Thanks to a high-performance on-board diesel engine, the large-scale crushers remain highly flexible, while up to 45 percent of the energy costs can be saved even in semi-stationary operations.
