Marine Steel Inclined Ladder (GB4444 – 84)
Top – left Table
The table provides specifications for two types (Type A and Type B) of marine steel inclined ladders, including the inclination angle (α), step width, and length range (in millimeters, mm).
| Type | Inclination Angle α | Step Width (mm) | Length Range (mm) |
|---|---|---|---|
| A | 45°, 50°, 55°, 60° | 700, 800 | 283 – 4657 (for 700mm step width); 261 – 3913 (for 800mm step width) |
| B | 65°, 70° | 400, 500, 600 | 331 – 3641 (for 400 – 600mm step width range, specific values vary with step width and angle) |
Right – hand Image
It is a technical drawing of the marine steel inclined ladder, showing a side – view and a top – view. The side – view illustrates the inclined structure of the ladder with steps, handrails, and other components, along with dimensional annotations. The top – view shows the layout of the steps and the overall width of the ladder.
Bottom Marking Example
For an inclined ladder with an inclination angle α of 60°, a step width of 600mm, and a length L of 1044mm, the marking is “Inclined ladder 60°×600×1044 GB4444 – 84”.
Note:
- The inclination angle α determines the slope of the ladder, which is important for safe and comfortable use.
- The step width is the horizontal distance between the two side – rails at each step level.
- The length range indicates the possible overall lengths of the ladder for different combinations of step width and inclination angle.
- The marking example demonstrates the standard way to label the product, including the key parameters (inclination angle, step width, length) and the standard number (GB4444 – 84).
