With the development and development of the Marine industry, the demand for engineering Marine positioning winches is gradually increasing. The winch with high performance and high stability will be more widely concerned and applied, and will also produce more demand. Compared with other positioning methods, the electric positioning winch has the advantages of compact structure, low price, easy operation, and fast response speed, and is the first choice in similar products.
PRODUCT DESCRIPTION
Positioning winch is a positioning method that uses anchors, chains, and mooring lines to tie the ship or floating structure to the sea to limit the drift caused by external forces and keep it in a predetermined position. Mainly used in ocean working vessels and offshore platforms, according to positioning requirements, it is divided into four points positioning, six points positioning, and eight points positioning.
(Customized according to specific working conditions, the following parameters are for reference only)
1. Rated tension: 2-1000kN
2. Working speed: 16--3m/min
3. Cable diameter: Φ6--65mm
4. Motor power: 0.75-70kW
5. Power supply: DC 12V, 24V, 48V; Ac 110V, 220V, 380V, 440V, 660V, etc.
The positioning winch can be divided into single drum and double drum, and the double drum positioning winch is generally a waterfall structure. The driving mode can be electric or hydraulic. Electric positioning winch can use variable frequency motor to achieve step-less speed change. Hydraulic winch continuously variable speed, electric and hydraulic positioning winch can achieve remote centralized control. Compare Prices.
Large positioning winch is generally in electric drive mode, easy to operate, easy to control and maintain, and the application effect is good. Due to the complex Marine operating environment, which is greatly affected by ocean currents, seabed, and wind waves, the force situation is complex and changeable, which puts forward higher requirements for the whole electrical control system.
Offshore wind power projects are commonly positioned in two ways: Multi-point anchorage positioning and dynamic positioning. Generally, it is more economical to adopt the anchorage positioning method in shallow water areas, but the operation efficiency and positioning accuracy are low. The dynamic positioning is more suitable for deep water operation, and can easily maintain the relative position with the pile foundation of the fan or other device, and the operation efficiency and positioning accuracy are higher. The purpose of a wind power installation platform positioning winch is to limit and reduce the movement of the platform under the action of wind, wave, and flow, maintain a relatively stable state, facilitate construction operations, and is one of the important systems of the platform.
The pipe-laying vessel positioning winch is used for anchor positioning in pipe-laying operations. The forward, backward, and transverse movement of the laying vessel is carried out by retracting and lowering the wire rope by the winch. In general operations, the positioning winch is used with a particularly high frequency, and the mechanism level is also at a higher level, which is important equipment for pipe-laying operations.
Pipe-laying vessels are generally equipped with 10 positioning winches for positioning and moving the vessel. The winch is arranged in the winch cabin under the main deck, with four fore and six stern. The cable leads from the winch, through the guide pulley, to the main deck, and then through the guide pulley, and the side of the rotating guide leads out of the ship, and connects with the working anchor.
Professional engineering of Marine optical cable, cable, and photoelectric composite embedment and maintenance as the "lifeblood" of Marine information and power transmission, submarine cables are indispensable in the construction of various large-scale ocean projects, it is especially widely used in countries with more islands and rivers. When laying or burying a cable ship, it is a continuous operation process, and the burying of a cable often takes several days, ten days, or even dozens of days. In this process, the sea conditions such as wind and waves change complicated, to prevent the cable from entangling or being pulled into the water, the ship is required to remain in place. To ensure the smooth operation of submarine cable connection, the ship is required to have a strong fixed-point positioning ability.
Submarine cable ship positioning system mainly has two forms dynamic positioning and anchoring positioning. An anchoring positioning centralized console can be set up in the central control room, which can realize the monitoring of the anchoring positioning system and the automatic control of constant tension positioning and ship moving functions.
Our winches are available in a range of capacities and sizes to meet different job requirements. With flexible design solutions, superior quality products and a wide range of after-sales services, we aim to maximize your work efficiency and safety, and also create maximum value for your business.
Selecting a winch with the right features and functions is critical to ensuring high work efficiency and safety. When choosing a winch for your application, you need to address the following basic information in order to identify the right one for the job:
· Rated load or pulling force
· Drum capacity (length and diameter of the wire rope)
· Line speed
· Winch working environment
· Electric or hydraulic drive?
· Single or double drum?
· Do you need a rope guide?
· Other special requirements

Application Area
The offshore positioning winch is mainly used in the following two types: anchoring positioning system and dynamic positioning system. Among them, the mooring positioning system has the advantages of simple structure, economical and reliability, convenient use and maintenance, etc. In not-too-deep waters (less than 1500m), the mooring positioning method is widely used in various types of engineering ships, FPSOs, and semi-submersible platforms.
The winches find applications in various industries, including manufacturing, construction, maritime, and material handling.
In manufacturing, companies may use them to position heavy components on an assembly line accurately.
In construction, companies can employ the winches for tasks such as lifting and placing construction materials with precision.
