The elevated crossing ramps (formerly known as angled stepfields) are a series of angled ramp units, arranged in a rotating pattern as shown.
They consist of three types of ramp units.
- 8x Conventional (Zero-height) ramps. These are the same as the ramps used in the continuous and crossing ramp terrains.
- 16x 50mm ramps. See below for details.
- 8x 100mm ramps. See below for details.
The 50mm ramps are so named because they are 50mm taller than the zero-height ramps.
Similarly the 100mm ramps are 100mm taller than the zero-height ramps.
Again, as for the conventional ramps, it is recommended that these be nailed or stapled together. Glue may be used for additional strength. Screws should be used with caution to avoid splitting the OSB.
