Our backhoe dredger launches into the water successfully
1. Brief intorudction
A backhoe dredger/floating excavator pontoon is an engineering vessel mounted on a ship or barge, primarily used for dredging sediments in waterways, ports, and underwater foundations to ensure safe navigation. Its working principle is very similar to that of a land-based backhoe excavator; a hydraulically driven boom and bucket excavate underwater mud, sand, rocks, or obstacles and load them into a barge for removal.
The core equipment of this type of backhoe dredger inclues:
A fully hydraulic backhoe excavator: driven by a diesel engine, with hydraulic cylinders controlling the movement of the boom and bucket;
A positioning system: typically using steel piles or anchor cables to secure the hull and ensure stability during operation;
A control system: the operator controls the entire dredging process from the cab, enabling precise operation.
Main features and advantages:
Suitable for excavating hard soil layers: such as rocks, large pebbles, weathered rock, and old revetment facilities, scenarios that other types of dredgers struggle to handle.
High operational precision: capable of precisely removing underwater obstacles, salvaging sunken objects, or dismantling embankments, often used for precision construction in complex waters.
Stable structure and high safety: The backhoe dredger is fixed to the forward deck of the hull, enhancing overall stability during construction.
Typical Application Cases:
"Rigangjun 6": One of the largest backhoe dredgers /floating excavator pontoon in China, with a length of 71.5 meters, a maximum dredging depth of 32 meters, and a bucket capacity of 20.5 cubic meters. Used for port basin dredging and new construction projects.
"Changying 8": my country's first large-scale backhoe dredger/floating excavator pontoon, equipped with a P995 excavator, a bucket capacity of 24 cubic meters, and a high-frequency hydraulic breaker, capable of handling dense sandy clay and hard rock.
"Zhenhejun 18": Guangxi's largest backhoe dredger/floating excavator pontoon, with a total length of 38 meters, a maximum dredging depth of 16 meters, and a bucket capacity of 5.7 cubic meters. Already in use on the Qinzhou Port Jingujiang Channel Project.
