About
A 3.4 m wide abutment 1.36 m high with two 3.4 m towers carrying a timber winch drum. The 3.1 m deck is nine planks with iron edge bands and two mooring posts, hinged on a pin line at the abutment front edge. Overall size 3.72 x 5.1 x 1.81 m in metres, +Y up, +Z forward, resting on y=0. Node deck pivots on the hinge line at y=1.36, z=0.02, parallel to X; node winch turns on the drum axis at y=4.5. Clips: open lowers the deck 90 degrees to horizontal over 2.4 s while the winch pays out, close raises it. Node TRS animation on named nodes only; no skinned rig, skeleton, collision or navigation data.
