The GDA series is a marine crane that mainly handles sand and gravel (aggregates).

In 1956, Shikoku Kenki Corporation (now SKK) manufactured the first marine crane to become the prototype of GDA.

Through the efforts in research, development and improvement, it became the current GDA.

More than 50 years after its birth, it has been widely used in the seas throughout Japan to be able to perform safe, reliable, and rapid handling work, even in unstable waters. In recent years, due to its high operability, it has also been used for dredging in rivers and dams.

In addition, the emission of CO2 transportation by ship is less than land transportation, and the marine cranes also play a role in eco-activities.
