Hydraculic System

Leader Dredger's hydraulic system is distributed throughout the dredger and is the core control system of the entire ship. The hydraulic system is a systematic project, with strong professionalism and comprehensiveness.

The main hydraulic components are: driving the reamer, driving the bridge up and down, controlling the ship to swing left and right through the traverse winch, and controlling the positioning pile up and down through the positioning pile cylinder. In addition, the trolley and the running anchor are also driven by the hydraulic system.

The advantages of the hydraulic system include: light weight per unit of power, small inertia, fast response speed, and easy start and stop. The working medium of the hydraulic system has a certain elastic shock absorption capacity, which can make the hydraulic transmission system operate stably and reliably. These advantages just meet the working requirements of the working mechanism of cutter suction dredger. Judging from the current mainstream design, hydraulic transmission is the main transmission method adopted by the dredger dredging equipment.

Dredging System

The dredging system is divided into a control system and a monitoring system, which is a highly integrated system.

Dredging monitoring system:

1. Understand the working status of all parts of the ship
2. Understand the working status of the main and auxiliary machines
3. Understand the real-time status of the hydraulic system
4. Understand the real-time status of the circuit system
5. Understand the operating status of the dredging pump
6. Understand the working status of the gearbox
7. Know the status of the cooling system, etc.

The main advantages of the monitoring system:

1. Improve the accuracy of dredging construction: Construction accuracy is necessary for high-end dredgers. It requires that the dredger can neither over-dig nor miss excavation during the construction process, and obtain an accurate excavation profile.
2. Improve construction efficiency: The work efficiency of the dredger directly affects the construction of related projects, and an efficient monitoring system can shorten the construction period.
3. Improve the working conditions of the operators: In the construction of the dredger, the operation steps of the entire process are simplified, the labor intensity of the operators is reduced, and the faults in the excavation process can be quickly found through the alarm display, saving maintenance time

Electric System

The electrical system of the dredger is composed of a main generator set, a standby generator set, an electrical cabinet, a charger and an operation console.

Among them the main generator set:

Provide power for sealing water pumps, miscellaneous water pumps, lighting and air conditioning during dredger work.

Dredger electrical cabinet:
It is the electrical equipment for controlling dredgers, including motors, gate blades, backup hydraulic pumps, fans, air switches for lighting and leakage protectors.

On the panel are:
voltage indicator, working/standby generator switch, standby hydraulic pump, sand pump, sealing water pump, miscellaneous water pump, start/stop button of the fan.

Battery for dredger:
Start the diesel engine, solenoid valve of the hydraulic system, 24v power supply lighting of the whole dredger, to provides the power.

Optional Items

Contain:

Trolley system

Anchor rod system

Flowmeter, concentration meter

Relay pump

Service boat

Dredger Spud

The lower end of the full range of Leader Dredger dredger spud is made of solid steel to ensure sufficient strength when penetrating the ground. When lifting the pile head, water can overflow from the two holes above the lower point. At the top, the hoist ring allows the crane to easily change the pile head.

Features of the dredging machine spud

1. Made of high-quality steel with high strength and wear resistance. Customers can also order other materials.

2. Longer service life and easy maintenance.

3. Simple disassembly and assembly, can be accurately adjusted.

Dredger Engine Room

Leader Dredger space is far superior to European and American ships, this design is more convenient for good ventilation system and maintenance of cabin components.

Reasonable layout of engine, hydraulic, circuit cold area system, etc., easy to locate and maintain system problems

Driving Cabin

The Leader Dredger dredging machine designed the dredger driving cabin as an integral detachable type. After disassembly, the maximum height of the dredger can be lowered, which improves the passage of the whole ship.

The connecting pipes and connecting lines between the dredger driving cabin and the engine room and deck are all designed for easy disassembly and assembly of joints to ensure that the dredger can easily disassemble and install the entire cab as a whole when passing a low bridge tunnel, which improves dredging. Practicality of the boat

Leader Dredger equips the driving cabin with more area of tempered glass, which is convenient for the driver to observe the surrounding situation while driving the dredger

The dredging machine driving cabin is equipped with diesel controller, suction pump pressure gauge, vacuum gauge, hydraulic equipment pressure gauge, etc., which can control the dredging system of the whole ship in the driving cabin

The operating system in the driving cabin has been tested by Leader Dredger for many years and has now achieved the advantages of simple operation, intuitive parameters and strong comfort.

Dredger Winch

The hydraulic winch of the cutter suction dredger is mainly a winch with a large rated load, which is driven by a reliable and low maintenance hydraulic motor.

The hydraulic winch of the dredger uses oil as the working medium, transmits motion through the change of the sealed volume, and transmits power through the pressure inside the oil.

Dredger Body

The hull of dredging machine adopts modular design. The main hull, deckhouse and working mechanism are modularized to achieve the independence of each unit and the convenience of disassembly combination, thereby shortening the construction and transportation cycle, and improving the applicability and economy of the dredger.

For modular dredgers, whether it is dismantling, assembling, or during transportation, the lifting of each modular unit is indispensable. In view of the different weight and size of each module unit, the form and arrangement of the lifting lugs are also different. As far as this ship is concerned, the main pontoon unit is heavy and there are large openings on the deck. Therefore, in addition to the heavy-duty lugs, the Leader Dredger will also install the lugs on the strong frame.

Dredger Engine

The Leader Dredger dredger uses a diesel engine.

When we choose the engine brand, we will test the engine performance
1. Matching degree with dredging pump
2. Is the engine power output stable?
3. Continuity of trouble-free operation
4. Fuel consumption
5. Durability
6. Volume and weight
7. After-sales response speed
8. Maintenance costs

Better engines can ensure the practicality, economy and rationality of pond dredge

Dredger Pump

Leader Dredger's full range of dredgers use Chinese professional pump manufacturers. And we will change the number of pumps according to the discharge distance and dredging depth, so as to provide stronger suction for the dredger.
Leader Dredger can be customized according to working conditions.

Cutter Head

The leader Dredger full range of dredger cutter head uses wear-resistant materials, which can meet many harsh dredging and mining environments. The cutter head can cut soil of many different types of materials, such as mud, sand, sandstone, minerals, and hard stones.

Cutter teeth
Our Cutter teeth can be replaced. The blade is equipped with an adapter to easily install and remove Cutter teeth. To meet the requirements of cutting more materials. The design of the blade of the dredge blade can minimize the overflow of the cutter. They introduce the cut material into the nozzle in the most effective way.

Desgin

There are 32 people in the technology and design department
12 senior technicians
20 technicians.
Can design and have all kinds of dredgers, civil, warships, marine engineering equipment qualifications.

We can do different types of China Classification Society CCS, American ABS, European BV, Italian RINA standard ships, dredgers, ships, etc.

The design of the cutter suction dredger involves disciplines such as mechanical manufacturing, electrical and electronic, hydrodynamics, computer technology, automation science, materials science, marine meteorology and even nuclear physics, and belongs to the category of system engineering design.

Leader Dredger specializes in analysis and design of dredger hull size, winch bridge, winch system, hydraulic system, positioning pile, mud pump system and its professional design, And repeatedly debug the power system, environment, vibration and noise issues

According to the dredging volume, digging depth index and soil quality of the construction project, the specific performance indexes such as the digging depth, soil breaking capacity and production capacity of the cutter suction dredger are determined.
This design concept is not only widely used in general commercial dredging fields, but also in military, scientific research and engineering fields.
The difference is that dredgers that serve commercial projects can improve the performance of cutter suction dredgers to achieve higher production efficiency and economic benefits, while dredgers used in military and scientific research fields can meet the needs of specific projects. Its economic performance is relatively lower.

In the current economic and social environment, a design that only focuses on technical performance without considering product economic indicators is almost impossible. The cutter suction dredger design is also based on practicality, reliability and other technical indicators, fully considering the economic performance in use, and weighing the unified indicators of technical performance and economic performance to achieve better design results.
