About
A 2.2 m base plate carries a five bay lattice mast with a head frame and a grooved sheave. The 1.5 m platform has three sided railing and an amber toe board; the counterweight is a 0.6 m block on a guide yoke. Overall size 2.2 x 5.08 x 2.32 m in metres, +Y up, +Z forward, resting on y=0. Node platform and node weight translate on Y in opposite directions; nodes ropeP and ropeW scale from the sheave axis at y=4.82. Clips: idle raises the platform 2.4 m and lowers the weight the same distance, then returns, over 6 s. Node TRS animation on named nodes only; no skinned rig, skeleton, collision or navigation data.
