A 2.6 m wide, 3.4 m clear gateway between two piers under a 3.2 m gatehouse block with a corbel band and five merlons. The grille is seven vertical bars with pointed feet tied by five horizontal bars and runs in a channel guide on each pier. Overall size 4.1 x 7.24 x 1.47 m in metres, +Y up, +Z forward, resting on y=0. Node grille translates on Y in its guides; node winch turns on the drum axis at y=5.42, z=0.62. Clips: open lifts the grille 3.1 m into the gatehouse over 2.2 s while the winch turns, close drops it. Node TRS animation on named nodes only; no skinned rig, skeleton, collision or navigation data.
