Reduce costs,
reduce maintenance time
& improve productivity

Constructions can be of such dimensions and/or weight making it impossible, if not very costly, to have it machined in a workshop. Such constructions include bridges, lock gates, large cranes, offshore constructions, ships, etc. Performing the machining work on site provides a very effective means of repair saving otherwise lengthy downtime to essential revenue savings.
