York Recycling (Processing) Limited, based at Alne near York in North Yorkshire, has taken delivery of a new Doosan DL300 wheel loader and DX225LC crawler excavator from local Doosan dealer, Stockton-based Construction Plant (Suppliers) Ltd. At the company’s Materials Recycling Facility at Alne, York Recycling sorts and processes consumer and industrial waste, construction and demolition debris, soil, wood and many other materials.
As well as general material handling applications, the Doosan DL300 wheel loader was purchased to meet the requirements for a new contract won by York Recycling for processing ‘frag waste’, the post-shredder output from shredding cars comprising a mixture of metals, plastics, textiles and other materials. Among the other materials is approximately 12 kg of earth trapped in the base of every shredded car and York Recycling extracts this soil by loading the frag waste using the DL300 wheel loader into a trommel, where it is separated from the other components in the waste. The recovered soil is perfect for use as lining and capping material for the landfill sites run by the company.
Impressive Local Record
York Recycling chose the DL300 wheel loader and DX225LC excavator based on the impressive performance of Doosan machines at the operations run by customers and other companies in the area. Alf Buckton, Site Manager at York Recycling’s Alne Materials Recycling Facility, said: "Several companies we work with in the area run Doosan products and we have always had good reports on their experiences and on the performance of the machines. We needed a dependable wheel loader for the new frag waste contract together with a new general purpose excavator and both the DL300 wheel loader and DX225LC excavator have proved to be ideal choices."
Under the supervision of Site Foreman, Robin Cockerill, the frag waste contract requires the DL300 to work continuously all day loading the trommel. Equipped with a large bucket, the DL300 combines a maximum capacity of 3.2 m3 with exceptional performance in terms of ease of handling, power, serviceability and durability. The 18.1 tonne DL300 loader is powered by the Doosan 169 kW DL08 turbocharged, electronically-controlled engine with a high pressure unit injector system and a state-of-the-art combustion system.
The DL300 offers a maximum torque of 1029 Nm at 1300 rpm for optimal traction and breakout force in loading-transport-handling applications. Breakout force is among the highest in its category at 162 kN, an important feature of this Z Bar designed loader. Two working modes (standard and economy) are available to optimise the consumption/productivity ratio and adapt the loader to the work at hand.
The DL300 offers a static tipping load with bucket of 14.5 tonne (at maximum reach with a straight frame) and a height at bucket pivot point of 4.00 m. The DL300 has a low turning radius at bucket edge of 6.36 m at the maximum steering angle of 40°.
Like all the other Doosan wheeled loaders, the DL300 uses a Powershift ZF transmission with ZF limited slip axles. The primary brakes are outboard, multi-disc wet brakes.
Operator comfort was also given high priority when the DL300 was designed. Improved visibility, heating and air conditioning, more room, an air-suspension seat, low noise levels and ample storage space are all features which enable operators to work for more hours with less fatigue. The cab also is a sealed filtered-air design, which means there is positive air pressure, minimizing dust ingress.
In addition to handling the frag waste and other waste materials processed at the Alne Transfer station, York Recycling uses the DL300 wheel loader to load soil and gravel into ADTs and other vehicles to be taken for lining and capping applications at the landfill sites run by York Recycling at Alne. Work on the landfill sites such as excavating, dressing linings and pipe installation also form some of the many digging and handling applications for the new Doosan DX225LC excavator.
A pleasure to operate
Both the DL300 and DX225LC are a pleasure to operate according to Robin Cockerill, who has had lots of experience in running machines of this type including over 15 years in the waste industry.
The DX225LC offers flexibility, convenience and low operating cost in a compact design with superior digging performance. Powered by a 6-cylinder Doosan turbocharged diesel engine providing 110 kW (148 HP) at a maximum governed speed of 1900 RPM, the DX225LC has an operating weight of 21.5 tonnes and a maximum digging depth of 5.76 m. The dump height is 6.83 m, while the maximum digging reach is 8.93 m.
The arm and bucket cylinders are sized to provide enhanced excavating force. Digging force over the bucket is 149 kN, while that over the arm is 105 kN. Use of power boost increases both forces by about 5%. Thanks to the high engine power and the high swing torque, the DX225LC can work efficiently on the slopes of the landfill sites.
Like all mid-size and heavy Doosan excavators, the DX225LC has as standard the ‘auto idle’ feature which reduces fuel consumption and noise and creates a more comfortable environment. The DX225LC combines maximum productivity with the ability to carry out jobs with precision and fingertip control. The auxiliary hydraulic flow and pressure allow the use of all typical attachments available on the market.
York Recycling (Processing) has been at the Alne site since 1991 and has ambitious plans for the operation to expand and further utilise the already extensive facilities on site. The company will shortly commission a new Synmet screening system which will be fed material by the new DL300 wheel loader and other material handlers on site. This will allow the company to recycle even more materials such as cardboard and wood for resupply to paper recyclers and other customers.
The company is also looking to expand production of refuse-derived fuels from the waste processed at Alne for use in the power industry and is complementing this with the installation of a new gas engine powered by gas from the landfill sites. The gas engine will provide power for recycling and processing machines such as the new Synmet system, an electric shredder and all the office facilities on Alne. Any surplus power will be supplied to the National Grid.
