THE VIEW AFTER THE NUMBERS
What the numbers suggest
Mitsui E&S designs and builds cranes, while also providing remote-operation technology and maintenance after delivery. The 17-crane Tokyo order specifies remote controls in an administration building and power supplied along the travel path.
Progress and improved profitability on existing large projects supported the earnings increase in the year ended March 2026. The work spans specifying the machine for its user, building it profitably and supporting it in operation. The new Tokyo order and the annual results show different stages of that work.
