Our Multipurpose River Dredging Machine is Designed and built-in Istanbul, and the Crocodile is suitable for a broad range of works in all types of bodies of water :
River Dredging Machine is versatility on the water makes it ideal 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 critical environmental feature of the River Dredging Machine is its ability to operate with low noise levels, equip it with a supercritical silencer that reduces noise to shallow levels.
Cleaning and restoring contaminated rivers and canals and other waterways / Reconstruction of shorelines / Creating wildlife habitats / Controlling vegetation / Installing water pipes, pipelines and submarine cables / Flood Control, Installing water pipes, channels, and submarine cables with the River Dredging Machine’s technology is possible to drive piles from the water. That protects the shores and enables pile driving at a considerable distance from the coast. River Dredging Machine moves independently in water with its propulsion system and excavator assembly. River Dredging Machine anchors with its spuds and does not need steel cables for dredging, which may disturb passing water traffic.
The machine arrives as a complete unit on a truck or cruises there by itself on water. River Dredger can walk on land and water.
River Dredger can remove floating or rooted vegetation, harmful stones, and trash from the bottom via the rake.
River Dredger can pump the soil through a pipeline to a discharge area located up to 1 km away by suction dredging. In this process, the soil is mixed with copious amounts of water, 80-90 % of the total volume.
Dredging in places where it’s hard or impossible to work with other machinery
( lakes, rivers, wetlands, shallow waters, harbors, canals, shorelines, industrial pools, under bridges, 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 a 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 plant has to be removed/controlled from the bottom
Where environmental dredging required


River Dredger’s dredging movements and anchoring can be done with hydraulic stabilizers. Two rear stabilizers, equipped with hydraulic tilting cylinders spuds. Depth control through hydraulic River Dredger has two front stabilizers with detachable floats and removable spuds. Propulsion system River Dredging Machine’s propulsion system is designed to provide maximum power with minimal disruption. The top speed is 8 knots. The
propeller can rise in shallow waters to protect aquatic vegetation and avoid disturbing riverbed sediment. Environmental dredging in a tropical and arctic climate.


River Dredging Machine’s cab meets the highest standards of comfort and ergonomic with excellent visibility. The pilot controls all hydraulic functions from the cabin and is equipped with fully adjustable deluxe seats, easy-to-reach controls, side windows that can open, and a range of standard and optional accessories like sunroof hatch and radio system, and gauging hydraulics/engine.


Dredger Machine equipped with a light, compact, low-pollution Cummins / Caterpillar vs. engine. The Crocodile excavator has the power to spare (250 to 375 hp – standard model: 250 hp).


One-piece body divided into seven watertight compartments for protection. Corrosion-resistant painting system for a minimum three years guarantee. Protective skid bars on the bottom. Slip-Safe deck. Handrails.


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 )

Bucket System

Several tools are available for backhoe dredging; a 400l bucket with teeth for everyday work, an 800l bucket for more significant sites, and a clamshell bucket for environmental dredging. The dredged material can be deposited on barges or, in narrow channels, directly on the shore with the bucket. Stone and trash removal can be done with the backhoe bucket, clamshell bucket. Larger stones can be moved to the coast, deeper into the water, buried, or they can, for example, be used to make a breakwater.
