Overview of the Amphibious Bulldozer

The amphibious bulldozer is an underwater excavation machine
that works in shallow waters.
It was developed and commercialized by combining water-tight underwater specifications with radio-control functions.
Thirty-six units have been manufactured and sold in and outside Japan in the past, and only the 5 units which are owned by the Company exist currently.
They have been adopted in dredging work in harbors and fishing ports, as well as in coastal construction work, such as river channel dredging, offshore breakwaters,
and man-made reefs.
In particular, they have been used widely in recent natural disaster repair work.
We have a track record of over 1,200 domestic construction projects, enabling us to accumulate expertise in construction.

By fully restoring all the parts, the bulldozers were revived for use in the Great East Japan Earthquake reconstruction projects

The amphibious bulldozers were overhauled one by one and fully restored in order to reconstruct the bridges, harbors, and ports that were damaged by the giant tsunami following the Great East Japan Earthquake.
