First Sandvik hybrid scalper delivered in Scotland
By Melissa Baker19 April 2022
Collier Quarrying & Recycling has taken delivery of the first QE442e Sandvik hybrid scalper in Scotland.
A producer of virgin stone and concrete products, the Fife-based company also carries out C&D waste recycling services and supplies aggregates to construction sector firms across the Edinburgh and Glasgow regions.
Its new hybrid “e” equipped QE442 can process up to 900 metric tonnes of mixed material per hour and is fitted with a Stage V Cat C4.4 engine, that will enable the company to switch between diesel and electric plug-in modes of operation.
This will help the firm to lower running costs, mitigate rising fuel costs, and reduce their carbon footprint.
The 38-tonne machine will be used for various onsite applications, including the recycling of aggregates and, when used alongside the company’s stationary cone crusher, for the processing of aggregates.
The QE442e Hybrid “e” variant is the largest of Sandvik’s second generation of mobile scalper machines, and it incorporates the same key features as the standard QE442 diesel model.
Its heavy duty 5.5 x 1.75m screen with high speed and aggressive throw is built for tough applications and can handle high volumes of infeed material. It offers the user-friendly features of the 2 series screens, including an electrical control system that improves both operational effectiveness and machine safety.
With a service interval of 4,000 hours and a 50% hydraulic fluid saving, the QE442e is also said to offer greater uptime and a lower cost of ownership compared to other conventionally powered models.
Duncan Collier, Managing Director of Collier Quarrying & Recycling, said, “There are less moving parts and filters to replace during maintenance, so we are saving not just a vast amount in terms of fuel costs but also less downtime by not having to re-fuel and carry out the regular maintenance checks associated with diesel machinery.”
Collier added, “We have always had a good working relationship with Sandvik and cannot fault the quality and reliability of their equipment. The majority of our fleet is now powered by electricity and it was the obvious choice to go with the hybrid model for our next investment.”
This latest investment is one of a number of actions taken by Collier to improve the sustainability of its activities.
These include the planting of thousands of trees on its site to screen the quarry and make a positive impact to the local area and the installation of a large wind turbine to generate renewable energy on site.
