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.

Warping head

ZG270-500

Casting defects cannot be avoided

Q345-B

High welding strength and slow wear.

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.
