Machined Casting Case Study

  • 70 tonne double girder crane for a machine casting company

1x 70 tonne and 2x 20 tonne double girder electric overhead travelling cranes

Our first project for this long established machine casting company was to supply the cranes needed for their new purpose built cast house. Due to the high capacity and anticipated work load it was essential to offer the right components for the application, as well as ensuring our tender was competitive we also had to work to a very tight timeframe so our installation would not hold up the other contractors working on the development. Because these cranes had to be built and delivered as single piece bridges (no joints) We acquired temporary premises locally with plant and access to enable us to assemble prior to delivering and installing.
The installation process went smoothly and once installed the cranes sat resplendent against the new building.
