Hitachi Takes To The Water
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. The marine and inland water construction company from Finland secured the contract to deepen the Mäntyluoto Pori harbour to 13.5 m early in 2010. The excavator was delivered last summer and has been working at the harbour since then.
The work consists of dredging 320,000 m³ clay and sand, and drilling and blasting 110,000 m³ of bedrock. The EX2500-6 has two booms of 13.6 m and 16 m, and three arms of 7 m, 9 m and 11 m. It is used with four buckets, ranging from 7.5 m³ to 14 m³, and its maximum dredging depth is 22 m. The booms, arms and buckets were all designed and built by Wasa Dredging. By November 2010 it had accumulated 3,760 working hours.
Special Equipment
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 EUR 13 million in 2010.
“Our customers and partners traditionally come from Finland, Sweden and Russia”, says 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.”
Continued Support
Rotator Oy managing director, Thomas Åhman says: “Wasa Dredging is satisfied with the performance of the EX2500-6 on the specialist project. It also appreciates the continued support it receives from Rotator through regular service checks and routine maintenance procedures.”
