WI equipment in action in Slovenia

Rock bucket for Hitachi

Nerinvest d.o.o. in Celje values on Austrian quality: for its new Hitachi ZX690LCH-7 from SMG Macchine, the Slovenian company was looking for a solution that could withstand abrasive material and minimise downtime. With a custom-made 3.2 m³ rock bucket made from Hardox® 500 TUF, Winkelbauer provided the perfect solution.

Tough conditions

Highly wear-resistant steel

Everyday life in the quarry at Nerinvest d.o.o. in Celje places the highest demands on man and machine: the rock there – a mixture of limestone and dolomite – puts a strain on the material every time the bucket is excavated. To withstand these stresses, the new rock bucket was equipped with the robust C-REX tooth system and consistently manufactured from highly wear-resistant steel. For maximum durability, HARDOX® 500 TUF is predominantly used (in the base, wear plate and side section) to minimise wear and significantly increase the operating times in the quarry.

Customer satisfaction as a benchmark

For Predrag Šinik, Managing Director of Nerinvest d.o.o., the move to Winkelbauer was a strategic decision:

“I was not satisfied with the previous products and was looking for a reliable solution. I found the right partner in Winkelbauer.”

Customised to your application

For the responsible Winkelbauer sales representative Jurica Petkovic, the long-term benefits for the customer are also a priority. The application in Slovenia emphasises the strategy of using high-end steels to reduce operating costs:

“For the customer, the longevity of the Attachment is an important point. We guarantee this by using highly wear-resistant steel, the HARDOX 500 TUF. Less wear means directly less downtime.”
