Heros has been a loyal Hitachi customer since 2011 and now has a fleet of ten machines including a ZX350LC-6 excavator and nine ZW-6 wheeled loaders.
During its ‘urban mining’ process, Heros extracts ferrous materials such as iron, and non-ferrous metals such as aluminium and copper, from incinerated bottom ash. The remaining material forms the basis for production of high-quality secondary aggregates used, for example, in road construction or concrete products.
On the 45-hectare site, the Hitachi machines are used to carry out a variety of tasks. The ZX350LC-6 medium excavator is used to open up the stockpiles of incinerated bottom ash, which can be stored on site for three to six weeks. One of the ZW310 wheeled loaders takes material from the pile and transports it to the feeder of the separation and processing equipment.
A ZW250-6 works in another section, where scrap metal is separated, while the company’s largest wheeled loader, a ZW370-6, is used to unload material from ships that dock in the adjacent canal. The smallest Hitachi wheeled loader on site, the ZW180-6, works for 16 hours/day in the 2,700m² non-ferrous upgrading facility.
“We chose the Hitachi ZW180-6 to work inside the plant, as it’s easy to manoeuvre and able to reach the height of the feeder,” says Peter David, head of machines and planning at Heros.
“It’s also versatile for tidying the stockpiles, loading the machine and cleaning the floor.”
To ensure the highest level of support, the machines are provided with full maintenance and service contracts, and extended warranty from Hitachi’s local dealer Pladdet (a sub-dealer of Hitachi Construction Machinery Nederland), which is conveniently located 20km away.
“Reliability and service nearby are the most important things for us,” says Peter David.
“It’s a very corrosive environment. The bottom ash can stick to machines like concrete or cement. In fact, the reliability of the Hitachi machines in combination with the maintenance programme ensures we don’t incur any unexpected costs.
