Booster stations can be used with trailing suction hopper dredgers and cutter suction dredgers. Sometimes multiple pumps are used along the discharge pipeline, providing additional power to the discharge pumping system of these dredgers. The dredger and booster stations together can then reach long distances.

The winch is suitable for railway crane, ship deck machinery, wharf and container crane, which can be directly installed in the reel in order to save space because of its compact structure, in addition , the design is also easy to install.

Product Description

Relong cutter suction dredger is a hydraulic dredger that uses centrifugal pumps with a rotating cutter head to loosen, lift and transport dredged material. Dredging machines are non-propelled dredgers.

Working method: The cutter will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position.

Project applications: Cutter suction dredgers are used wherever the seabed is hard rock. They are used for larger dredging projects such as navigation channels and port development and maintenance and land reclamation and in major projects such as the Panama Canal and the Suez Canal.

Types of dredging materials: Cutters are powerful and are capable of dredging all kinds of material in water including hard rock.

They are able to effectively dredge: silts, clays, sand, gravel, cobbles, fractured rocks and sound (unfractured) rocks.

With more than 30 years of experience in dredgers production, JULONG mainly manufactures small and middle sized cutter suction

dredgers.JULONG dredgers are of modular structure which is convenient for the disassembly and transportation. Its other

characteristics include reasonable design, easy operation, long duration and running continuity. The dredger can be widely used for

maintenance dredging, infrastructure dredging, environmental-friendly dredging and sand mining etc.

Cutter suction dredger is a kind of ship that is widely used in beach dredging projects. It uses the front end of the suction pipe. The cutter suction pipe is equipped with a rotating cutter device to cut and agitate the river bottom sediment, and then through the suction pipe, the Mud, mud transport, mud unloading and other work processes can be completed continuously at one time. It is a high-efficiency, low-cost dredger and a good underwater excavating machine. The split structure makes the installation and transportation of the cutter suction boat simpler and more flexible, can be easily transported to any location. With its robust design, it is the preferred choice in its class due to low maintenance, excellent fuel consumption and high productivity levels.

A Jet suction dredger has a high pressure mechanical device, a jet head, perpendicular to the ship's axis, mounted in front of the suction head.It is developed from general cutter suction dredger. It is a new type of hydraulic dredger.
The performance of the jet suction dredger costs less than bucket wheel suction dredger and also cutter suction dredger. The high pressure water pump impinges the water through the high pressure water gun to bottom sediment layer, and the sediment splattered around the suction head, pumped by the sand suction pump through the suction pipe to the designated position. That water spray processing and pump suction process will finish the entire dredging process.

RELONG Polyethylene dredging pipe (HDPE Pipe) is one of the latest applications of polyethylene pipes. HDPE Pipes are manufactured and welded with two HDPE flange adapter and two steel flanges, which also called as "HDPE flanged pipe", from which two pipes can be connected together easily by flanges. Polyethylene dredging pipe produces with common standards of polyethylene pipe and these two pipes have flange head. Polyethylene flanges are provided for dredging, have cross-sections which accelerate and smooth fluid flow and reduced the pressure on the pumps.

Relongdeckcraneis a kind ofship's hoisting equipment usually set in the cabin deck whichcontentshigh technology of electricity, liquid, machine integration of deck.With the advantageof easymanipulation, impact resistance, good performance, safety and reliability, itcan make a good use of the limited space of port, yard and other places.It hashigh working efficiency and good adaptability to the goods, especially for the dry bulkcargo handling.

1. The ship crane comes complete with skid assembly suitable for deck, mounting and electric hydraulic power pack.
2. The fitted winch of deck crane is capable of lifting 4t at all angles.
3. This deck crane is built to provide long time.
4. operation against harsh marine environments.
5. stainless steel pipes and fittings as standard.

Booster pumps/booster stations may be based on land or on a floating platform and may be almost as powerful as the dredger they are supplementing. Occasionally, they are placed on the deck of a vessel but usually they are attached to the floating pipeline along its way from ship to shore.
