On Barge Excavators
Dredging Ships
Feature
Big Digging Forces
The Hitachi dredging ship yields big digging forces from the ample-powered engine and sophisticated hydraulic system making efficient use of engine output. The result is productive digging into sea-floor deposits, from sand/soil to soft rocks. Assortments of buckets are available depending on types of sea-floor sediment and jobs.
The bucket
The bucket can dig in various sea-bottom deposits, from sand/soil to crushed stones. Available for powerful dredging, sea-floor leveling, and rock uplifting.
The ripper bucket
The ripper bucket allows direct digging in soft rocks with high efficiency.
The one-point ripper
The one-point ripper can efficiently break sea-bottom bedrock.
The hydraulic breaker
The hydraulic breaker can easily break groyne and revetment.
The clamshell grab
The clamshell grab allows easy positioning, and grabbing of sea bottom deposits, especially through a limited opening of excavation.
Agile Front Movements
Agile front movements, and combined operations are clear advantages of the Hitachi hydraulic excavator. The boom moves up swiftly, and the upperstructure turns smoothly for higher dredging efficiency and productivity.
Easy Sea-Bottom Finishing
Good maneuverability and combined operations enhance ease-of-positioning and precision sea-bottom finishing. This helps increase job efficiency.
2-Lever Control
All operations can be done by 2-lever control through the advanced hydraulic system. This gives easy, comfortable operation with less fatigue.
Simple Job-to-Job Travel
With the spud and front attachment raised, the dredger can move to a next dredging position. No need for cumbersome pre-work preparation to shorten a job schedule.
Compact Barge
Despite its big dredging capacity, the hydraulic excavator needs a compact barge that can move around even in shallow water and confined sites, facilitate dumping onto a truck on the pier, and evacuate into a small harbor in the case of heavy weather.
Simple Maintenance
The hydraulic excavator on barge can easily be maintained. No need for cable replacement, of course. Lubricating the front attachment is also easy, using a grease gun with hose reel. Key portions, susceptible to corrosion, are protected with seawater-resistant paint.
