Wärtsilä’s Trieste delivery centre, which produces engines for large ships and power plants, has seen an increase production levels and speed of throughput. When planning these improvements, it found limitations in the weight and dimensions of the existing cranes and needed to make them compatible with a tracked conveying system that transports engines through the manufacturing and testing processes.
Konecranes won the competitive tender to supply a wide range of customised cranes and lifting equipment for this project. One important customisation was to modify the structural steelwork of two large cranes, which will lift loads of 200 and 125 tonnes, by using stronger 355-grade structural steelwork. These modifications compensate for limitations on crane weight and dimensions, as well as assisting in meeting the coverage areas that the work cells demand.
The large cranes in particular, are contributing to increased productivity, as Wärtsilä had previously been forced to employ a combination of two smaller cranes with a spreader bar, to move its largest engines.
The new lifting equipment is radio controlled. Because over 20 cranes were supplied for this project and the fact that the radios needed to be integrated into a large population of similar controls, Konecranes decided to employ the DECT digital radio standard as the platform for its remote control software, RemoX. This provided the large number of channels required, and eliminated interference problems.
Almost all of the cranes have now been delivered and installed, ahead of Wärtsilä’s project completion target.
