Marine Mooring Post
I. Technical Drawing
This Marine Mooring Post technical drawing provides a comprehensive set of views for a cast – iron bollard with a round chassis and semi – baffle, including a front view with a sectional view (I – I at 1:10 scale), a location view (1:20 scale), and a plug view (1:10 scale). The main front view is at a 1:10 scale, clearly showing the overall shape, internal structure, and key dimensions of the component.

Drawing Instructions
- All dimensions in the drawing are in millimeters (mm).
- The dimensional tolerances of each part in the drawing are in accordance with the IT – I 1550kN round -底盘半挡型铸铁系船桩 (round chassis semi – baffle type cast – iron bollard) standard, for example, refer to relevant figures.
- The top of the bollard column should be cast with “250kN”, “350kN”, “450kN”, and “550kN” characters.
- After reaming the bolt holes, asphalt should be applied for anti – rust treatment.
- After installing the bollard, the shell should be filled with cement mortar.
- The surface roughness of the bolt holes should be uniform, with the rest as required.
- Welding should adopt T42 welding rods.
- The outer轮廓尺寸 (outer contour dimensions; likely a translation error, probably meaning unmarked outer dimensions) in the drawing should have a smooth transition without sharp corners.
- The surface of the bollard shell should be painted with red lead and anti – rust paint twice, and the bolt – head surface can be coated with red lead oil.
- The dimension L in the table is L = L0+[0 +8+20].
II. Bill of Materials
