Electric Single Drum Winch
Application
An electric single drum winch is a type of marine electric winch that features a single drum for winding and unwinding cable. The drum is powered by an electric motor, which provides the power to lift, lower, and hold heavy loads. The electric single drum winch can be delivered with a one, two or three speed electric motor.The single drum design is simple and straightforward, making it a popular choice for basic winching applications where the load can be easily controlled and managed. The single drum also helps to keep the winch compact and lightweight, making it easy to install and maintain. Some key features of electric single-drum winches include a compact design, easy operation, low maintenance requirements, and a variety of control options, including manual and automatic control. The winches are available in different sizes and capacities to suit a range of applications and operating conditions.

Consequence
Drum
To reduce costs, reduce the thickness of the drum.
The thickness of the drum is too thin, which is not conducive to the load and wears quickly.
Produced in strict accordance with product production standards, with moderate thickness.
The thickness is moderate, which is good for loading, wears slowly, and does not cause the product to be too heavy to increase the transportation cost.

Installation Precautions
Before assembly, you must be familiar with the structure of each part of the winch to prevent wrong installation and missing installation. When assembling, pay attention to the following matters: all parts need to be cleaned, and iron filings and other stolen goods should not be brought in. During the assembly process, lubricating oil should be applied to all running parts and rolling bearings at any time.
Installation Conditions
1. The winch should be a qualified product that has been checked and put into storage by the quality inspection department of the factory.
2. Before the winch is loaded into the ship, there should be random materials such as the manufacturer's factory certificate, ship inspection certificate and operation manual.
3. Under normal circumstances, the hull in the winch installation area should be installed after the welding and calibration work is completed.
4. The installation drawing of the winch and the drawing of the winch base.
5. Principles, techniques and requirements for the installation of marine auxiliary machinery.
Installation Process
1. The positioning of the base of the marine winch from the centre line of the ship, the frame number position and the height from the midline of the deck must meet the requirements of the base drawing.
2. The installation and inspection of the marine winch base are qualified.
3. When using a steel backing plate, the plane of the base fixing backing plate should be processed first, the flatness is ≤2mm, the surface roughness is Ra3.2, and the outward slope is 1:100.
4. After installing the marine winch, use the hanging wire method or the laser method to confirm the horizontal axis of the marine winch drum, the tolerance is 3mm/m, and the height and the distance from the midship position are ±5mm, and the inspection is qualified.
5. Whisk with steel backing plate.
6. Epoxy resin casting pad.
7. Prepare copper gaskets. Before the winch fixing bolts are tightened, check that the gap between the winch base and the base fixing pad is less than 0.5mm, and no gaskets are allowed; when it is greater than 0.5mm, it is allowed to have no more than 3 thin copper gaskets, and it is not allowed Use a half sheet of spacers.
