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.
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.
Strong in shallow waters
Safe work through remote wireless operation
Transport and bulldoze without allowing soil and sand to escape
Ripper unit allows bedrock to be crushed
Work can be conducted directly below bridges
Temporary roads
Temporary jetties
Amphibious bulldozer construction method
Conventional method
Sand is sucked out of gaps between
stone due to the impact of waves.
Amphibious bulldozer construction method
Prevents sand from being sucked out by removing gaps
through compacting and rolling
Swift evacuation
Small over-excavation amount
Allows underwater bulldozing and leveling
Offshore breakwaters
Artificial reefs
Artificial beaches
Harbors, fishing ports
Jetties
