1.14 inch hydraulic sand dredging machine for coastline protection

 

Cutter Suction Dredger is self-propelled or non self-propelled, portable cutter suction dredger. Hull can be dismantled and re-assemble easily with box structure. It is equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and so on. It is widely used in sand-excavating, river dredging, channel maintenance and broaden, desilting, blow fields stretched, port construction, etc.

 

2.Introduction of our dredger 

 

The dredger we produced is self-propelled or non self propelled portable cutter suction dredger. The hull uses dismantled and box-like structure, assembly at working site, which equipped with horizontal shifting devices, cutter ladder lifting devices, spud devices, deck crane and so on. It can also be equipped with anchor boom and trolley devices to increase capacity.

Generally, it has functions of sand or mud dredging, port building and deepening, desilting, etc.

  

3.Cutter Head 

For one cutter head, there are 5 blade,6 or 7 teeth equipped on one blade. There is material Cr. for easy-wearing proof. Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.

 

The cutter motor is hydraulic driven low speed and high torque heavy duty design. The cutter motor is mounted on the cutter front piece on the ladder end. A special cover is provided to protect the motor from damage due to sand, rocks and debris. The cover can be removed from easy inspection and maintenance.

 

4.Hydraulic winches 

For hosting the ladder, one hoisting winch is provided on the front of the main pontoon mounted on a stiffened foundation. The winch is hydraulically driven through a reduction gearbox build in the winch structure. The winch has a disc brake that is automatically activated in case of pressure drop. The winch is operated from the control cabin and has one fixed speed.

For ladder side pull, two winches are provided on the front of the main pontoon mounted on a stiffened foundation. The winch is hydraulically driven through a reduction gearbox build in the winch structure. The winch has a disc brake that is automatically activated in case of pressure drop. The winch is operated from the control cabin and has variable speed.

 

5.Hydraulic system

Hydraulic system is the most important parts of river sand dredger and wheel bucket dredger. The hydraulic system requirements are very high and strict; it’s the main artery of the entire sand mining dredge. Lateral traction winches, lifting winch and cutter head of the dredgers are driven by hydraulic motors.

We use hydraulic to drive the whole dredger including winches, cutters, hydraulic oil cylinder, etc. The valve is REXROTH, and the control system of hydraulic is SIEMENS PLC.

 

6.Dredge Pump (Warman Technology)

The dredge pump is high efficiency made from wear resistant casting impeller and liners fitted on heavy duty shaft and high quality roller bearings.

 

The impeller is fitted on the shaft by trapezoid thread directly machine on the shaft end. The shaft sealing is a water cooled sealing that can be replaced after wear life. The impeller is a special type of double curved vanes high efficiency and wear life optimized tested in laboratory and onboard of dredgers. The impeller is fixed on the shaft by trapezoid thread machined directly in the impeller hub.

 

The pump casing has a shape of a volute designed of a high efficiency and wear life optimized tested in laboratory and onboard of dredgers. The pump liners are made of high wear resistant materials and thick wall thickness to maximize the wear life. The casting covers are made from fabricated steel stiffened where necessary and machining to fit the case and the liners.

 

7.Ladder for cutter suction dredger 

The ladder and cutter head for cutter suction dredger are mainly made of ladder steel structure, suction pipe, left and right traversing pulley, ladder lift and down pulley block, hydraulic pipe, cutter head, cutter head driving hydraulic motor, gear box etc.. The ladder is fixed on the main pontoon by two axle pins. Its main function is to install suction pipe and make the cutter head descend to certain depth and cut sand.

 

8.Deck crane and hydraulic oil cylinder 

The deck crane that installed beside the sand pump is a kind of lifting equipment with cantilever and mainly used as a tool when repairing the sand pump and replacing the wearing parts.

Hydraulic oil cylinder, usually used to lift or fall down the spuds to help the dredger's moving. The power will be offered by hydraulic system.

 

9.Operation cabin 

The dredger is equipped with an operation cabin that provides good visibility all around and good safely performance because of two lockable doors and a front window. And the dredger cabin is equipped with rest chair, air conditioner, the noise is very low, suitable for long working time. To pass low bridge and for road transport easily, the controlling room can be dismounted.

 

10.Tested before delivery 

All our products will be tested in the testing center before ex-factory and dismantle for shipping to the port. In the tested process, all testing is same as the dredger working in the work site, operating performance and products’ safety will be tested and recorded. This test will reduce debugging time in the working site and increase training time for workers.
