The first Hitachi Sumitomo SCX A-3 series model in The Netherlands has been acquired by Gebr. De Koning to work on concrete structure, waterworks and foundation contracts. The new SCX1000A-3 crawler crane – launched at Bauma in April 2013 – was delivered to the Papendrecht-based company by the domestic dealer of Hitachi Construction Machinery (Europe) NV (HCME Domestic) earlier this year.
Gebr. De Koning bought its first Hitachi crane (a KH100) in 1978 and since then has enjoyed an excellent working relationship with HCME Domestic. Its current line-up of crawler cranes includes the Hitachi KH100, KH150, KH180, KH230 and KH300, and the Hitachi Sumitomo SCX550. In addition, it has four Hitachi excavators: an EX30 mini; ZX210LC-3 and ZX250LC-3 medium crawler excavators; and a ZX210W-3 wheeled excavator.
With a team of 80 employees, Gebr. De Koning is versatile to the needs of its largest customers: ProRail (the government body for the national railway network); the Port of Rotterdam (the largest port in Europe); and the City of Rotterdam (the second largest in The Netherlands). Its ongoing construction projects include such structures as bridges, tunnels and quay walls, as well as subcontracting for house building, utility and civil works.
“We prefer to buy rather than hire our crawler cranes, as they are used on most of our projects,” says Managing Director Leo van Dijk, who is responsible for the company’s fleet of machinery. “We continue to choose Hitachi machinery, because of the competitive price, high quality and overall reliability of the products. In addition, HCME’s reaction time to our requests is good and we have had a positive overall experience with our existing fleet.”
The SCX1000A-3 can be used as a 70-, 80- or 90-tonne machine, due to various configurations from six counterweight parts. The crane’s dimensions mean that it is easily transportable, and can be efficiently assembled and disassembled when moving between job sites. Gebr. De Koning also specified the options of a third winch and a wider skywalk on the 30-metre boom for enhanced safety and easier assembly. The machine is powered by a Stage IIIB-compliant Isuzu 6HK1 engine – with a power output of 210kW at 1,900rpm – and comes equipped with a diesel particulate filter that automatically captures and burns dirt particles from the air.
“The flexibility and versatility of the new crane were the key factors in deciding to buy the SCX1000A-3,” adds Leo. “The reliability and robustness of Hitachi Sumitomo cranes are well known, and they are therefore in demand on a global basis with high residual values. The environment is also of paramount importance, for example when working on a ProRail project the CO2 emissions are carefully monitored and the fuel consumption is also an important factor.”
Each Gebr. De Koning machine has a designated operator and Corné van der Vlist has been given responsibility for the new Hitachi Sumitomo flagship product: “The SCX1000A-3 is very smooth and precise, and the power is more than adequate for lifting and hoisting. The view from the cab means that I have excellent visibility of the site and the work that I am doing.
“The monitor is useful for measuring the height and reach, and this means that it is easy for me to move a load forward, for example by as little as half a metre. I feel so relaxed in the cab, because it is such a comfortable and pleasant working environment. The joysticks and pedals are ideal for my natural sitting position, so I don’t have to stretch.”
