This also applies to cable, chain, and webbing.

Gear that is anchored includes anchors, rocks, trees, tripods, trucks, etc.

A "bight" is a simple loop in a rope that does not cross itself.

A "bend" is a knot that joins two ropes together. Bends can only be attached to the end of a rope.

A "hitch" is a type of knot that must be tied around another object.

"Descending devices" (e.g., ATCs, Brake Bar Racks, Figure 8s, Rescue 8s, etc) create friction as their primary purpose. The friction in descending devices is always considered when calculating forces.

The "Safety Factor" is the ratio between the gear's breaking strength and the maximum load applied to the gear (e.g., 5:1).

Working with the CMC Capto

The CMC Captos shown on this page will be available in the next version of vRigger. If you own version 13.0, contact us to see if a prerelease version of vRigger is available that includes The CMC Captos shown on this page.

The CMC Capto combines a rope "grab" and a pulley. This creates complications for vRigger, prevents ropes in vRigger from connecting correctly

Two versions of the Capto are available. The one piece Capto, shown here, is useful when you want to create an image but it can't be used with force calculations because one of the ropes isn't actually connected to the Capto. A sample file provides additional instructions on using this Capto.

There is also a two-piece Capto in vRigger (with a "top" and "bottom" half). You can can connect ropes to each of these halves and then connect the two halves as shown here. This is a bit of a pain but it does work and will usually allow you to calculate forces.
