RigForce Anchor Bench
RigForce Anchor Bench
RigForce Anchor Bench is an offline-first rope-rigging force workbench for recreational climbers, arborists, SAR volunteers, and rope-rescue students. Instead of napkin estimates for angle multipliers or haul friction, you build anchor geometries on a clear top-down workspace, assign rope and hardware from a seeded strength library, apply knot efficiency, design mechanical-advantage systems, compare layouts, and export a one-page rigging brief with forces, weakest link, and safety factor—educational physics aid, not a trip diary or gear checklist shell.

Anchor geometry workbench: place 2–4 anchor points on a top-down stage, snap included angles (30°/45°/60°/90°/120° guides), and watch live resultant vectors plus per-leg load-share percentages update as you drag.

Seeded rope & hardware library: dynamic/static ropes by diameter, slings, carabiners, pulleys, and progress-capture devices with manufacturer-style MBS defaults; add custom pieces and apply personal derating factors.

Knot & hitch efficiency panel: choose from a seeded catalog (figure-eight on a bight, bowline, clove hitch, double fisherman’s, Prusik, Autoblock, etc.), apply efficiency % to the working line, and display residual strength against the chosen safety-factor target.

Mechanical-advantage builder: assemble common 3:1, 5:1, and 9:1 haul stacks from pulleys and progress-capture devices, dial friction-loss assumptions, enter load mass, and read required pull force and theoretical advantage.

Scenario presets with guided inputs: pickoff, controlled lower, simple highline sketch, and tree-work TIP—each pre-fills recommended SF targets (5:1 / 7:1 / 10:1) and highlights the weakest link in the chain.

Side-by-side layout compare: open two saved workspaces and contrast peak leg force, angle multiplier, weakest component, and overall safety factor before choosing a plan.
