Rotator Oy, Hitachi Construction Machinery (Europe) NV’s official dealer in Finland, has supplied Wasa Dredging Ltd with an EX2500-6 excavator as the base machine for a backhoe dredger for the project to deepen Mäntyluoto Pori harbour to 13.5m.
The Hitachi excavator was delivered last summer and has been working at the harbour since then. The work consists of dredging 320,000m³ clay and sand, and drilling and blasting 110,000m³ of bedrock.
The EX2500-6 has two booms of 13.6m and 16m, and three arms of 7m, 9m and 11m. It is used with four buckets, ranging from 7.5m³ to 14m³, and its maximum dredging depth is 22m. The booms, arms and buckets were all designed and built by Wasa Dredging.
The backhoe dredger is one of several pieces of special equipment, including split barges and drilling platforms, that Wasa Dredging has constructed for its offshore and marine and inland water construction work since 1997. It specialises in underwater drilling, blasting and dredging of hard materials. The company currently has around 30 employees and had a turnover of €13m in 2010.
“Our customers and partners traditionally come from Finland, Sweden and Russia, said Wasa managing director Kristian Backlund. “They include the former Finnish Maritime Administration, city councils, local government bodies and major construction contractors. We are currently expanding our market to mainland Europe, and we plan to build new equipment for these markets in 2011-12.”
