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.

Through the monitoring system, you can understand the working status of all components of the whole ship, the working status of the main and auxiliary engines, the real-time status of the hydraulic system, the condition of the electrical circuit system, the running status of the pump, the working status of the gear box, the cooling system, etc.

At the same time, the centralized control unit controls the working parts of the dredger in real time through the operation lever and the like. One person can operate the parts of the entire ship.

Electric System

The electrical system of the dredger consists of a main generator set, a backup generator set, an electrical cabinet, a charger and an operating console.

In order to improve the power supply efficiency of the dredging machine power station and ensure the safety, stability, balance and continuous power supply of the entire ship, the dredging machine power station is equipped with a power management system for the entire ship’s electricity. The system is designed for fully automatic management according to requirements.

(1) Separate the main high-power equipment from the ship’s sensitive equipment, such as generators, transformers, frequency converters and motors.

(2) Take isolation and filtering measures for the auxiliary power supply used by the electric propulsion system equipment to avoid using the same power supply with sensitive electronic equipment.

(3) The power generation equipment on the ship, the motor base and shell, the switch cabinet shell, the exposed metal lighting, the metal appearance and shielding layer of all cables, etc. should be grounded, and the metal grounding conductor should be connected to the hull to obtain the smallest ground resistance . The goal

Feature of electrical system

(1) Good economic benefits.
(2) High reliability, high degree of automation and good operability.
(3) Low noise and low vibration.
(4) Wide speed range, large driving force, easy forward and reverse rotation, small size, flexible layout and convenient installation.

Optional Items

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 winch of dredging machine adopts hydraulic transmission.

According to the location and function of the dredger, the working winch is divided into the bridge hoisting winch, the left and right lateral shifting working winch, the anchoring winch, and the positioning pile hoisting winch.

Various working winches can be steplessly adjusted within a certain rope speed range, and are equipped with manual stop pins.

The main features of the winch are:

1. Small size
2. Lightweight
3. Strong and wear-resistant
4. Anti-corrosion
5. Safe and convenient
6. Fast maintenance

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 economy, reliability, and longevity of the special diesel engine for dredgers are the first, and the size and weight are the second. Leader Dredger usually matches the customer's dredger with Caterpillar or Cummins engines. Of course, the engine brand customers have the final decision.

Featuers required for diesel engine:

1. Good economy. Higher effective thermal efficiency, which can reduce fuel costs.
2. The power range is wide, which can provide more choices for the dredger
3. Small size and light weight, which is conducive to the layout of the ship's engine room
4. Good mobility. Easy to start, good acceleration performance, wide speed and load adjustment range.

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 reamer cutting system includes all devices that move the reamer, cut the soil, and drive the soil to mix with environmental water.

Among them, the cutter type is the most common. Different dredging tools have different impacts on construction requirements and the surrounding environment. A reasonable dredging tool should be selected in the dredging project.

Features of dredging machine cutter head:

1. The cutter teeth are designed as sharp teeth or chisel teeth, which improves the cutting and crushing ability of the tool, and also improves the adaptability of the tool to different soil qualities;
2. The tooth design is made of high wear-resistant alloy steel, which enhances the wear resistance and greatly improves the service life;
3. The reasonable design of the tooth structure makes it extremely easy to disassemble and replace

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.
