Volvo L120H and L150H large wheel loaders have been supplied to Rail Freight Services on a long-term contract for Lytag, handling pulverised fuel ash (fly ash) at the Drax power station in Yorkshire.
The 20-tonne L120H is deployed loading fly ash into the plant, where it is mixed with a binding agent, pelletised, then burnt at around 1,100°C and separated into various sizes. The 25-tonne L150H is in the stock yard, unloading the bays of separated material and loading on to outgoing wagons. Around 3,000 tonnes a week of material is being moved between the two machines.
Since the fly ash has a density of around 0.5 tonnes/cu m, both machines have been equipped with large capacity high-tip buckets of 5cu m and 7cu m, respectively.
Powered by Stage-IV final Volvo 8- and 13-litre engines, developing 276hp in the L120H and 300hp in the L150H, the excavators are coupled with Volvo designed powertrain components.
Other options installed on both units include RDS Loadmaster weighing devices, automatic braking systems, boom suspension and hydraulic attachment brackets, meaning both can revert to standard general-purpose buckets.
