Kojimagumi Co Ltd

Since its foundation, our company has been engaged with soil, working in ocean civil engineering and focused mainly on dredging. Over the years we developed various new technologies and machines, many of which have been granted patents. Among them is a grab dredger equipped with a 200-cubic-meter grab bucket, a pneumatic feed system for transporting sediment by air pressure through a pipeline to a remote disposal site, and many other special equipment and machines with high performance.

In recent years, industries and individuals have been expected to give consideration to preservation of the global environment. It is therefore important for our facilities and operations to be energy-saving, and not to cause air, water, soil or noise pollution. Dredged sediment should be recycled. Our equipment and machines developed based on this philosophy are sure to be beneficial to everyone, exhibiting their full performance and high efficiency   Grab specifications:   Capacity 106 m3 (P.L) , 76 m3 (W.L) Weight 477 tons height 16 m width 12.8 m (open) , 11.55 m (closed) Depth 5.64 m Cutting force 990 tons (Lip edge) Hydraulic cylinder Inside diameter φ 580 × stroke 2,100 × 4
