The new E-Dredger features the E-Crane super-balanced equilibrium principle for smooth, efficient, energy saving operation in dredging and related applications. These includes operations such as piling, ship salvaging, heavy construction with dynamiting, classic dike works, construction of breakwaters, land reclamation, and beach and embankment preservations.
The balanced counterweight design keeps the boom, stick and grab in near perfect balance in all positions, according to the manufacturer. This minimizes tipping so the unit can be mounted on virtually any type of barge, with or without spud poles.
The low E-Dredger height allows maximum mobility under bridges and overhead obstructions. Tail swing is less than 25 ft. (7.5m). The all-electric E-Dredger operates on only 300 hp (225 kW), and is designed and constructed for easy disassembly and reassembly.
The grab’s closing power enables it to remain clamped shut when filled and above the water level. The Automatic Superlift Mode helps reduce the need to discharge material from the overloaded grab when exiting the water. The grab rotator, load cell, and all connections and greases are designed and fitted for underwater applications. The open stick construction eliminates buoyancy problems and improves placement accuracy, according to the manufacturer.
E-Dredgers are available in a wide variety of outreach, downreach and lifting capacities.
The hydraulically adjustable operator cab provides optimum visibility. The crane monitoring system includes readout screens in the cab with remote access connections for troubleshooting and reporting, plus integrated software for visualization and guidance.
