Our Multipurpose Dam Dredging Machine is Designed and built in Istanbul, the Crocodile is suitable for a wide range of works in all types of bodies of water :
Dam Dredging Machine is versatility on water makes it suitable for uses ranging from heavy work to fast emergency response. Its powerful engine, propulsion system and pumps, superior mobility and sophisticated positioning equipment place it in a class by itself. Another important environmental feature of the Dam Dredging Machine is its ability to operate with low noise levels, is equipped with a super critical silencer that reduces noise to remarkably low levels.
Cleaning and restoring contaminated rivers and canals and other water ways / Reconstruction of shorelines / Creating wildlife habitats / Controlling vegetation / Installing water pipes, pipelines and submarine cables / Flood Control,Installing water pipes, pipelines and submarine cables with the Dam Dredging Machine’s technology is possible to drive piles from the water. This protects the shores and enables pile driving at a considerable distance from the shore. Dam Dredging Machine moves independently in water with its own propulsion system and excavator assembly. Dam Dredging Machine anchors with its own spuds and does not need steel cables for dredging which may disturb passing water traffic.
The machine arrives as a complete unit at the site on a truck or cruises there by itself on water. After arriving at the site on a trailer there is no need for costly crane assistance, because the machine simply “walks” in and out of the water without any outside assistance. Dam Dredger can remove floating or rooted vegetation, harmful stones and trash from the bottom via using rake
By suction dredging Dam Dredger can pump the soil through a pipeline to a discharge area, which can be located up to 1 km away. In this process the soil is mixed with large amounts of water, 80-90 % of the total volume.
Dredging in places where it is difficult or impossible to work with other machinery
( lakes, rivers, wetlands, shallow waters, harbours, canals, shorelines, industrial pools, under bridges, in tunnels etc. )
Where unique/versatile dredger is needed, which can both pump and excavate
Where it is not feasible to mobilize several one-purpose machines
( cutter suction dredger, backhoe dredger, excavator, tugboat, assembly cranes or assisting vessels for anchorage to the site )
Dredging in places, where there is water traffic jam
Where pipelines/submarine cables/pile driving in water or on the shoreline is needed
Where vegetation do not permit conventional dredger
Where floating or rooted vegetation has to be removed / controlled from the bottom
Where environmental dredging needed
The Crocodile Multipurpose Dredger’s independent dredging movements and anchoring is based on hydraulic stabilizers.
2 rear stabilizers, equipped with hydraulical tilting cylinders spuds. Depth control by means of hydraulic
2 front stabilizers with detachable floats and removable spuds.
Dam Dredging Machine’s propulsion system is designed to provide maximum power with minimal disruption. Maximum speed is 8 knots.The propeller can be raised in shallow waters to protect aquatic vegetation and avoid disturbing riverbed sediment. Environmental dredging in tropical and arctic climate.
Dam Dredging Machine ‘s cab meets the highest standards of comfort and ergonomic with excellent visibility. The pilot controls all hydraulic functions from the cabin.It is equipped with with full adjustable deluxe seats, easy to reach controls, side windows that can be opened, and a range of standard and optional accessories like sun roof hatch, radio system and gauging for hydraulics/engine
Equipped with a light, compact, low-pollution Cummins / Caterpillar vs. engine.The Crocodile excavator has power to spare (250 to 375 hp – standard model : 250 hp).
One piece body divided into 7 watertight compartments for protection. Corrosion resistant painting system for minimum 3 years guarantee. Protective skid bars on bottom. Slip-Safe deck. Hand rails.
Maximum bucket reach : 6.5 m to 7.85 m through 180º Maximum depth : 6.5 m
Breakout force (from bucket cyl.) : 77 kN ( depends on selected option )
Digging force (from bucket cyl.) : 40 kN ( depends on selected option )
Lifting capacity at max. reach : 16 kN ( depends on selected option )
There are several tools available for backhoe dredging; a 400l bucket with teeth for normal work, a 800l bucket for bigger sites, a clam shell bucket for environmental dredging. With the bucket dredged material can be deposited on barges or, in narrow channels, directly on the shore. Stone and trash removal can be done with the backhoe bucket, clam shell bucket. Larger stones can be moved to the shore, deeper into the water, buried or they can, for example ; be used to make a breakwater.
