Trapdoor decks are working platforms that include an access hatch so users can climb through the deck using the intended internal route. This allows safer movement between levels without climbing around the outside of the tower. They are a common feature on modern scaffold towers because they support better access control and safer platform entry.
Scaffold Tower Basics
Platform height is the height of the deck level where the user actually stands on the scaffold tower. It is different from working height, which is the approximate height the person can safely reach from that platform. Understanding platform height helps you compare towers properly and choose one that gives enough access without encouraging unsafe stretching.
