Installation dimensions

The excavation is sized according to national standards. Please contact GRAF or your local distributor for
free sizing.
The dimensions of the excavation bed based on the above sizing are as follows:
- Excavation length (sizing) + 1 m (3'–3.4") working space (all round)
- Excavation width (sizing) + 1 m (3'–3.4") working space (all round)
The excavation height depends on the number of layers, traffic loading and planned connection heights /
shafts.
The excavation must also be designed in accordance with national standards "Excavation pits and
trenches" or similar standards. In particular, this includes the slope angle that has to be selected
depending on the soil type for depths of ≥ 1.25 m (4'–1.2").
