v0.31:Trap design
| This article is about an older version of DF. |
Auto-Defense System: Grate Hall
This is a trap designed to be placed at a long, hallway-like entrance of your fort. It operates by use of a long series of floor grates suspended over a drop linked to a single pressure plate in the middle of the hall. Due to the inability of floor grates to be fixed to other floor grates, the system relies on on a few supporting pillars in the middle of the system. These pillars reduce the auto-capture efficiency of the system to 85% if they are built as wagon-friendly floors. You will also wish to link the system to a lever, meaning that every floor grate will require two mechanisms to operate.
A design for a bare-bones capture system is shown below. Variations on this may include a drowning pool full of cave crocodiles or a barracks full of friendly military personnel at the bottom, or perhaps a bottom much further down, connected by a door to your (giant cave spider silk sock) stockpile.
