RigForce Anchor Bench

See real vector loads and safety factors before you commit weight. Visual anchors, seeded gear and knots, MA haul math, and printable rigging briefs—fully offline in seco

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.

SEE LOADS BEFORE YOU COMMIT Place 2–4 anchor points on a top-down stage, snap included angle guides (30°, 45°, 60°, 90°, 120°), and watch live resultant vectors plus per-leg load-share percentages update as you drag. Understand angle multipliers and load share before weight goes on the system.

SEEDED ROPE & HARDWARE LIBRARY Work with dynamic and static ropes by diameter, slings, carabiners, pulleys, and progress-capture devices using manufacturer-style MBS defaults. Add custom pieces and apply personal derating factors so the math matches the gear you actually carry.

KNOT & HITCH EFFICIENCY Choose from a seeded catalog—figure-eight on a bight, bowline, clove hitch, double fisherman’s, Prusik, Autoblock, and more—apply efficiency to the working line, and display residual strength against your 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 in seconds.

SCENARIO PRESETS & SIDE-BY-SIDE COMPARE Start from pickoff, controlled lower, simple highline sketch, or tree-work TIP presets. Each pre-fills recommended SF targets (5:1 / 7:1 / 10:1) and highlights the weakest link. Open two saved workspaces and contrast peak leg force, angle multiplier, weakest component, and overall safety factor before choosing a plan.

PERSONAL KITS & PDF RIGGING BRIEFS Name kits (sport rack, alpine, arbor climbing) with default hardware MBS values and apply them in one tap. Export a one-page PDF via ShareLink or print with diagram snapshot, forces table, gear list, knot efficiencies used, SF target vs result, and a short educational safety disclaimer.

CHARTS, WIDGET & SHORTCUTS Explore interactive angle-vs-multiplier curves and MA friction sensitivity. Glance at your last SF result and a classic multiplier cheatsheet from a Home Screen widget. Spotlight and Siri can return an angle multiplier from on-device data—no network required.

Built as an educational physics aid for training and pre-rig planning. Fully offline. Not a trip diary, gear checklist shell, or substitute for certified instruction, field judgment, or applicable standards.
