Pilot Ladder (ISO799 – 2004)
Top – left Image
It shows a pilot ladder in a folded state, placed on a surface. The ladder appears to be made of wooden steps and rope or chain side – ropes, with metal hardware at the ends for attachment purposes.
Top – right Image
This image displays the pilot ladder in an unfolded and ready – for – use state, hanging vertically. It clearly shows the arrangement of the steps and the side – ropes, with metal fittings at the top for securing the ladder to a ship or other structure.
Middle – left Technical Drawing
It is a detailed technical drawing of the pilot ladder, showing a side – view with dimensional annotations. The drawing includes details of the steps, side – ropes, and metal fittings, with measurements in millimeters (mm).
Bottom Table
The table provides specifications for pilot ladders with different numbers of steps, including the length of the ladder (L), the length of a certain section (L1), the step spacing, and the weight.
| Number of Steps | Step Quantity (Note: likely a redundant or mis – labeled term, probably just emphasizing steps) | Stop – step Position | L (mm) | L1 (mm) | Step Spacing (mm) | Weight (kg) |
|---|---|---|---|---|---|---|
| 5 | 1 | 8th step | 2310 | 1860 | 25 | 22 |
| 6 | 2640 | 2170 | 28 | |||
| 7 | 1 | 8th step | 2970 | 2480 | 31 | 25 |
| 9 | 3300 | 2790 | 34 | |||
| 10 | 1 | 10th step | 3630 | 3100 | 37 | 27 |
| 11 | 3960 | 3410 | 40 | |||
| 12 | 2 | 8th step, 12th step | 4290 | 3720 | 43 | 43 |
| 14 | 4620 | 4030 | 47 | |||
| 15 | 2 | 8th step, 14th step | 4950 | 4340 | 50 | 50 |
| 17 | 5280 | 4650 | 53 | |||
| 18 | 2 | 8th step, 14th step | 5940 | 5270 | 64 | 64 |
| 20 | 6270 | 5580 | 67 | |||
| 21 | 2 | 8th step, 14th step, 20th step | 6600 | 5890 | 70 | 70 |
| 23 | 6930 | 6200 | 73 | |||
| 24 | 3 | 8th step, 14th step, 20th step | 7260 | 6510 | 76 | 76 |
| 26 | 7590 | 6820 | 79 | |||
| 27 | 3 | 8th step, 14th step, 20th step, 26th step | 7920 | 7130 | 82 | 82 |
| 29 | 8250 | 7440 | 85 | |||
| 30 | 3 | 8th step, 14th step, 20th step, 26th step | 8580 | 7750 | 88 | 88 |
Note:
- The “stop – step position” indicates the position of the steps that are designed to prevent the ladder from slipping. For example, “8th step” means the 8th step from the top (or bottom, depending on the context) is a stop – step.
- The step spacing is the distance between two adjacent steps.
- The values in the table are for reference, and the actual product may vary slightly according to specific production requirements. The length L is likely the overall length of the ladder, and L1 is the length of a particular section of the ladder, but the exact definition of L1 is not clearly specified in the table alone.
