Adapting OBA’s bulk crane: a new front and chair for the control cabin
OBA is a transhipment port for bulk goods in Amsterdam. The company has a terminal in the Netherlands’ capital city’s western docks (Westelijk Havengebied). One of the 60-ton quay cranes was manufactured by Chinese crane construction company ZPMC. OBA decided to improve several features on the crane, such as the layout of the front of the cabin to improve all-round vision, and the operator’s chair in the middle of the cabin. Merford Cabins manufactured a bay window with an ergonomic operator’s chair that has now replaced the front of the cabin.
In the ARA range (Antwerp, Rotterdam, Amsterdam), OBA is an important player in the transport of bulk goods, such as coal and minerals, which are delivered by sea for further processing in Western European countries. The goods are used, amongst others, in power production companies and in the steel and animal feed industries. Thanks to excellent rail, road and inland waterway links, OBA occupies one of the most strategic positions in Western Europe. In 2014, OBA asked Merford to design a bay window that would replace part of the cabin.
Merford conducted a sightline study to determine the best layout. Among other things, sloping sides were developed to minimise reflections and two low side-windows can be opened electronically to still provide good vision if there is a lot of dust. An Ergoseat S positioned in the bay window enables the operator to maintain an ergonomic posture at all times, thus considerably reducing the likelihood of absenteeism due to physical complaints. Although it was a challenge, Merford also worked on the links for the electrical connections and the assembly. Replacing the front of an existing cabin was something new for Merford, but the assembly went smoothly and the refurbished cabin sailed through its first days of production with flying colours.
