The telescoping boom is used to perform clamshell dredging and crane work under low bridge girders.
Low space dredging work (backhoe)
| Low space dredging work using a specially equipped backhoe barge |
A backhoe is deployed at a low position, the same as the river water level, and the height of the machine is lowered as much as possible to perform dredging work in a low space.
Narrow channel work (crane)

We connect barges and small barges that have been transported or shipped by land, install crawler cranes, and perform crane operations in narrow waterways.

Stacked barges and small barges that have been transported or navigated by land are connected together and equipped with backhoes to carry out dredging work in narrow waterways.
Rubble dumping in deep water
Using an equipped DP vessel (dynamic positioning vessel) as the mother vessel, riprap is dumped at great depths of over 100m, using a multi-beam to manage the dumping.
Earth anchor driving work
We use a mini-sep barge to drive earth anchors from the water into quays and revetments where construction from land is difficult.
