Our company has more than 200 employees, including 6 professional senior engineers on dredger building and researching, and more than 30 intermediate grade technical personnel. They specialize in designing and building dredgers and sand mining machinery. We have established a good cooperative relationship and signed co-operation agreement with a number of Ship Design Institute such as Jiangsu Ship Design Institute, Yancheng Ship Design Institute and Shanghai Ship Design Co., Ltd, etc..

In order to secure and develop new markets, we set up after-sales offices abroad. We have signed agreement with Domestic Provincial Port Authority, Waterway Dredging Department and River Authority. We have signed agency agreements with trade companies in following countries such as Malaysia, Indonesia, Bangladesh, India, Brazil, Argentina, Benin, Egypt, Poland, Nigeria, Ukraine, Saudi Arabia, Pakistan, Philippines, Cambodia, etc. In recent years, our dredgers and gold mining equipment have been successfully exported to these countries.

HICL HWMD250 800M3/H WATER MASTER DREDGER:

HWM Water Master Dredger includes functions of cutter suction, digging, grabbing, piling, weeding etc. as a whole, can be used in shallow areas such as, coastal beach, inland lake, city rivers, channel and reservoir, industrial settling pond, can be used fordredging, reclamation, desilting, weeding and piling etc. Its features are as follows:

1. Disposal easily, no need for crane, can move on a road and get in and out of the water without too much cost;
2. Self-propulsion with propellers;
3. Work stable, with spuds and support legs to keep balance;
4. High efficiency, with submersible mud pump and cutter compound equipment ensuring high slurry density (around 25%);
5. One person operation. Workers with excavator operation skills can operate easily after a little training;
6. Can be used in closed channel, shallow areas, industrial pond, reservoir etc. where other dredgers can not work;
7. Lights on dredger are available to make sure constant work for maximum efficiency.

Amphibious excavators, also called swamp excavators, marsh buggies or floating excavators, are a kind of special excavator that
can be applied in many diversified conditions such as soft terrains, swamp land, shallow water, seashore even deep water.

Amphibious excavator can complete many dredging works that normal crawler excavator can’t complete, for example, stream channels
dredging of civil works, reinforcement of beach cofferdam, excavation of fish ponds, capital construction of farmland irrigation
and water conservancy.

1. Customized designs will be made based on customers' project requirements. Our engineers are all experienced in dredger designs for many years. The cooperation with China leading ship design institutes and professional colleges help us to ensure the design quality.

2. All the HICL dredgers are built by skilled workers and inspected strictly to assure the high quality and durability. Each finished dredger will be fully tested at our launching site before delivery to make sure it work smoothly when delivered to customers.

3. Best parts will be used for the dredgers, like world famous Cummins engines, Shijiazhuang pumps, Hangzhou gearboxes, Simens PLC control system.

4. Hydraulic system is one of the most important parts of cutter suction dredgers. The cutter head, ladder winch, swing winches, spud & spud carrier, anchor arm are driven by hydraulic motors for higher efficiency and durability. Reputed brands are used for the other hydraulic parts like hydraulic pipes, hydraulic pumps, hydraulic valves.

5. The dredgers are dismountable. So they can be disassembled and assembled easily. Thus it is convenient for the transportation by road, rail or water.

6. Professional engineers will be sent to the project site to insist the customers on the installation, commissioning, testing of the dredgers and training of operators.

Continuous Duty(CON):

*Intended for continuous use in applications requiring a load factor of 70–90 percent.
*Typical vessel applications include: ocean-going displacement hulls such as fishing trawlers, freighters, tugboats, bottom drag trawlers, and deep river towboats.

Features:
1. Advanced hydraulic sand pump model, CAD 3D design, high efficiency and obvious energy-saving.
2. Large dredging sand depth, high density of dredging mud, good pump NPSH and strong suction lift ability.
3. Strong through-put. The sand pump can persistently discharge gravel, high plastic soil lump,etc.
4. The dredge pump can be directly matched with either motor or diesel engine.
5. Wide application. The sand pump can be used in various kinds of soil quality. Generally, the dredge pump is matched with an impeller with 3 or 5 pieces of vane. At the same time, the impellers can be provided with various diameters and vane types to suit kinds of working conditions.
6. Little hydraulic loss, high efficiency and low oil-consumption.
7. Little volume, light weight.
8. Steady operating, little vibration, low noise.
9. Simple & reliable construction, easily disassembly & assembly, convenient maintenance.
10. Reliable sealing without leakage.
11. Long operating life of parts. 

Description & features:
Hydraulic system is one of the most important parts of cutter suction dredgers. The cutter head, ladder winch, swing winches, spud & spud carrier, anchor arm are driven by hydraulic motors for higher efficiency and durability. Reputed brands are used for the other hydraulic parts like hydraulic pipes, hydraulic pumps, hydraulic valves.

An integral hydraulic system includes hydraulic oil tanks, hydraulic pump, hydraulic valve manifold, solenoid valve, hydraulic pipes, hydraulic components, electrical actuator and so on.
