Key Technical Features:

• Model: Kobelco Amphibious SK380XDLC-10 Excavator
• Operating Weight: Approx. 37.8 tons (depending on attachment).
• Undercarriage: Dual pontoon system with corrosion-resistant steel and wide tracks for buoyancy and low ground pressure.
• Engine: 255 HP HINO J08E, diesel engine with turbocharger designed for fuel efficiency.
• Hydraulic System: Advanced Kobelco hydraulics with high-flow pumps for continuous dredging.
• Attachments: Compatible with dredging buckets, rakes, and hydraulic cutters.
• Applications: Canal dredging, lake development, wetland restoration, reclamation works.

For deep dredging, piling, and breakwater construction, long-boom excavators are essential. These machines extend their reach up to 32 meters, making them perfect for underwater excavation and slope protection.

Key Features:

• Reinforced booms and arms for long reach operations.
• Precision controls for dredging and slope work.
• Strong hydraulic systems for consistent power.

In marine and coastal works, access to elevated digging levels is critical, especially when operating around quay walls, breakwaters, and port structures. Al Marwan supplies high-bed excavators engineered with elevated chassis to provide greater working height, better visibility, and improved stability in marine environments.

Key Features:

• Elevated Chassis: Raised undercarriage offers enhanced clearance for working above quay edges and waterfront structures.
• Improved Visibility: Operators gain a better line of sight over high sea walls, barges, and work platforms.
• Stability on Uneven Terrain: Wide-track design ensures reliable operation in reclaimed or rough coastal ground.
• Adaptability: Can be fitted with long booms or specialized attachments for dredging, slope work, or heavy-duty excavation.

Model available: Kobelco SK850LC High-Bed Excavator (22-meter Boom)

Operating Weight: 85  tons.

Boom Reach: 22 meters with custom elevated design.

Chassis: Elevated heavy-duty undercarriage for additional clearance.

Hydraulics: High-flow dual-pump hydraulic system for demanding marine tasks.

Visibility: Elevated cab design with panoramic operator view for quay and offshore works.

Stability: Wide undercarriage for enhanced stability in reclaimed or rough ground conditions.

Applications: Dredging from barges, quay wall maintenance, port construction, slope reinforcement.

Strong foundations are critical for marine infrastructure such as bridges, ports, and offshore platforms. As the official dealer for ABI piling rigs, Al Marwan supplies German-engineered machines designed for precision, reliability, and efficiency.

Key Features:

• Mobilram Systems: Advanced rigs for sheet piling, vibratory driving, and drilling.
• Versatile Drilling: Capable of working in sandy, silty, and rocky seabeds.
• Reduced Vibration Impact: Protecting surrounding structures during piling works.
• Applications: Ideal for foundations of bridges, piers, quay walls, and offshore platforms.

Our ABI drilling equipment have been extensively deployed in UAE marine projects, ensuring stable foundations that meet international safety and durability standards.

Marine projects often require heavy lifting capabilities, whether for quay wall modules, precast girders, or offshore infrastructure. Al Marwan offers a fleet of large Kobelco crawler cranes known globally for Japanese precision, clean layouts, and fuel efficiency.

Key Capacities:

• Models ranging from 60 tons to 600 tons, adaptable for both land and marine use.
• High-load charts optimized for long-duration lifts in port and bridge works.
• Precision hydraulic control systems for safer operations in confined marine zones.

Efficient handling of aggregates, dredged materials, and sand stockpiles is a cornerstone of marine operations. Al Marwan’s wheel loader fleet spans a wide range of global brands, including Komatsu, Volvo, JCB, and others.

Key Capacities:

• Compact 2–5 ton loaders for confined coastal or port zones.
• Medium 10–15 ton loaders for aggregate handling.
• Large 20–35 ton loaders for quarry, harbor, and reclamation projects.

With fuel-efficient engines and operator-friendly cabins, these loaders deliver consistent productivity while minimizing downtime.

For marine embankments, reclamation shaping, and heavy earthmoving near coasts, large bulldozers are indispensable. Al Marwan supplies dozers from industry leaders Caterpillar and Komatsu, built for strength and durability.

Large Models Include:

• Caterpillar D8 and D11 models – ideal for grading and high-volume push operations.
• Komatsu D475A – one of the most powerful bulldozers available, built for extreme workloads.

Beyond specialized marine heavy equipment, Al Marwan provides a comprehensive supporting fleet to ensure smooth execution of every marine and coastal development.

• Dump Trucks (Rigid & Articulated): Caterpillar and Komatsu rigid haulers for high-capacity loads, alongside Volvo A40G ADTs for challenging terrain.
• Compactors & Rollers: Dynapac Redline single-drum soil compactors, double-drum asphalt rollers, and pneumatic-tyred rollers for embankment stability.
• Powerscreen Crushers & Screeners: On-site aggregate processing units such as Chieftain 2100X, jaw crushers, and cone crushers to recycle dredged material into usable fill.
• Utility Service Trucks & Water Trucks: Supporting logistics, dust suppression, and site service across marine zones.
