Until recently, ZUO International, the waste and recycling company based at Kunowice in Poland, used only wheel loaders. However, when the opportunity arose to invest in new mobile equipment, the company decided to purchase a material handler for the first time, a new Doosan DX250WMH‑5 wheeled model.
ZUO International was established thanks to the investments and capital of Sirius Finance S.A. (Luxembourg). As a Municipal Waste Treatment Facility, it provides comprehensive waste management, recovery and disposal services. The new Doosan machine was purchased in response to the growing waste stream and to improve processes.
“With an additional unit,it is much easier to manage the machines in a way that guarantees their optimal useand best performance. This is why we didn’t buyanother wheel loader,but rather a material handler. This machine enables usto easily sort materialsfrom a waste heap or load waste into the shredder with precision, becausethe operator, when located several metres above ground level,can clearly see the inside of the working chamberand can properly distribute the load,”explains Rafał Kościukiewicz, operations manager, ZUO International.
Careful Choice from a Field of Five Competitive Suppliers
The purchase decision was made carefully on the basis of a tender procedure in which five companies participated. The best proposal was presented by Grausch i Grausch Maszyny Budowlane Sp. z o.o., the exclusive Authorized Doosan Dealer in Poland. The proposed machine met all the technical criteria set by ZUO International and had the most attractive price. “TheDX250WMH‑5model perfectly meets our needs.Its high performanceand range in excess of 11 m make the machine a perfect tool for handlingeven the heaviest materials.The new machine is used to loadgreen waste into a shredderand screening unit, but we know – based on previous experience from other facilities – that it can alsohandle bulk waste,” adds Rafał Kościukiewicz.
He also stresses other important aspects that led to the selection of the offer from Grausch i Grausch Maszyny Budowlane, when he adds: “The 6-cylinder, 6-litre engine,relatively large for this class of machine,providesthe bestoperating parameters.We were also impressed by the lownoise level in the cab, much lower than in the machines from the competitors.”
Initially, ZUO International was concerned about a drop in shredder loading efficiency, as the wheel loader used so far has a 4 m3bucket, while the new material handler is equipped with a semi-open 5‑finger gripper with a capacity of 0.6 m3.
As Rafał Kościukiewicz assures, these fears were completely unfounded. The new machine is fast and guarantees shorter work cycles, so the work efficiency is comparable. He summarises the situation: “The Doosan material handlermeets our expectations and we are verysatisfied with it. It does whatit’s supposed to. Our operatorlikes working in it because of the noticeablepower reserve and spacious, comfortablecab.”
Rafał Kościukiewicz also speaks positively about the Doosan dealer: “The machine was deliveredon time, and the cooperation with the salesrepresentative and service offer wereperfectly satisfactory. However,this is not a surprise,as two years ago we purchased a Doosan DX300LC-5 crawler excavator from Grausch i Grausch,so we have already had the opportunityto work with them. The machine has workedover 5000 hours so far, but thanks toprofessional, regular maintenanceit is still in perfect condition and hasn’thad any problems. We are very satisfied withGrausch i Grausch’s services.”
The DX250WMH‑5 25-tonne material handler was added to the Doosan range at the beginning of 2019. It is based on the Doosan 21‑tonne DX210W‑5 wheeled excavator. It was designed for the toughest applications, such as handling scrap metal. A factory-installed electrical generator used to power the electromagnet eliminates the need for modifications, and additional features, such as cab guards, frame guards, additional work lights and solid rubber tyres, increase the safety of waste handling. The DoosanCONNECT telematics system is standard for the DX250WMH-5 machine and comes with a 3‑year subscription. It sends location information and a full range of machine operational information to the owner, dealer and Doosan. This information is sent with the help of a simple user interface, accessible online via a web-enabled computer or smartphone. The telematics system enables owners to monitor their Doosan machinery and effectively manage maintenance to reduce general operating costs.
