Sandvik Mobile Crushing and Screening has announced the completion of its new electric tracked crushing and screening train, setting, it says, new industry benchmarks for sustainability, productivity and fuel efficiency.
The new QH443E is Sandvik’s flagship Q-Range electric-driven cone plant. It takes a significant step towards bridging the gap between tracked mobile, wheeled portable and stationary plants by combining electric drives and track mobility on a single platform.
The QH443E features an updated tracked platform with a diesel/electric generator-based drivetrain, Optik™ automation system, My Fleet remote monitoring and the Sandvik CH440 Hydrocone crusher.
This advanced cone crusher is known for its versatility and ease of setting adjustment through the Hydroset CSS regulation and protection system, which optimises production and keeps track of liner wear through the CLP, Constant Liner Performance technology, Sandvik says. With a choice of several chambers, throws and settings for a wide range of applications, this enables operators to fine tune the specification and improve capacity.
Running the QH443E via the onboard genset can result in up to 25% fuel savings and a 78% reduction in oil usage compared with previous generations, Sandvik claims.
Combining electric drive technology with tracked mobility, the QH443E is designed with safety, sustainability and total cost of ownership in mind, making it ideal for secondary or tertiary crushing in applications including mining.
The QH443E electric cone crusher completes Sandvik’s electric train, which includes the UJ443E fully electric jaw crusher (launched in 2023) and the QA452e hybrid triple-deck Doublescreen (launched in 2022).
Built on a new fully-electric track platform, the Sandvik UJ443E features high-quality components and the latest generation Sandvik CJ412 jaw crusher. It offers up to 25% reduction in fuel consumption and up to 30% increase in throughput compared with previous models. The fully-electric track drives also reduce hydraulic oil usage by up to 91%, Sandvik says.
The Sandvik QA452e Doublescreen technology typically outperforms traditional screens by up to 30% offering a tailored rock processing solution for mining, quarry & recycling industries. Its hybrid “e” drive can provide the most economical and efficient energy source, the company added.
Both the UJ443E and QH443E feature an onboard genset and electrically driven components onboard. This setup allows both units to operate either by connecting to an external electricity supply or via the onboard genset using HVO or diesel.
Using an external supply or grid connection provides further advantages, including significantly lower running costs, extended drivetrain service intervals, reduced refuelling time, minimal on-site emissions and lower noise levels.
Additionally, the alternator is sized accordingly so that a downstream screening plant could be operated from the plant’s onboard genset, simplifying servicing and maintenance and improving overall fuel consumption while also providing up to 20% decrease in fuel consumption compared with running separate units, Sandvik says.
Manny Maloney, President, Sandvik Mobile Crushing and Screening Division, says: “Sandvik Mobiles has always been at the forefront of innovation, and completing the development of our tracked electric train marks a significant step towards a more sustainable and cost-effective future for the crushing and screening industry. This is just the beginning of our commitment to developing solutions that improve the productivity, safety, and sustainability of our customers’ operations. With its advanced capabilities, this technology is also particularly well-suited for heavy-duty applications, including large quarries and mining operations, where maximising uptime and reduced environmental impact are critical.”
The QH443E will be available in the European market from mid-March and globally later in 2025.
