Dredging / Coastal Protection Various solutions for your dredging and coastal protection tasks

Dredging and Coastal protection

Removing sediments and debris from the bottom of rivers and other water bodies made easy with larger sized heavy duty cycle cranes with large hopper dredger. This is also correlated to coastal protection reclamation where larger cranes and material handlers can move bigger armour rocks and faster cycle at the same time.

Up to 300 t with two 450 kN winches (Duty cycle crane)
Up to 42 m reach, covering 5,500 sqm work area (Balance material handler)
Save up to 50 % energy costs
Non corrosive paint work (optional)

Well-engineered and designed SENNEBOGEN 653 E enables the crane to work next to fragile environment such as lamp post and fall protection guard rails.

SENNEBOGEN 6180 heavy duty cycle crawler crane with an IEV dragline bucket of 4 cu.yd (3000L) reshaping a new shoreline to better withstand the impact of constant waves through dredging process.

SENNEBOGEN 6113 E lowering precast concrete elements for efficient coastal protection. A job which requires a wide stable track.

Coastal protection / Dredging Challenges

Deep underwater sediments

The natural process of built up sediments that block waterways from downstream can be very deep. SENNEBOGEN heavy duty cycle cranes with excellence below ground level load chart warrant a job done even for heavy built up.

Different size, different weight

Coastal protection such as armour rocks comes in different sizes. With an orange peel grab, material handlers can lift the load without doubt as the number of armour rocks in a single grab are predetermined by the size of an orange peel grab.

Timing of tides

Sea levels rise and fall. A self-assembly crane is important for fast setting up for the day job, so that the task can be carried out efficiently before the rise of tide in the noon.

Uneven ground

As soil is getting eroded, often there is not any space for a crane to have a secure footing. A boat mounted duty cycle crane solution is required. This solution is able to take advantage of the duty cycle crane strong tagline winches to toss and guide the grab.
