Flexible options let you specify:
-
The
minimum safety factor.
- The weight of individual gear such as loads and
litters (you can even specify the weight of a single
carabiner).
- The friction of gear (including carabiners, pulleys,
and brake bar racks).
- Where force labels are displayed.
- The display units (kilonewtons, kilograms, or pounds).
- And much more...
The force calculations understand the complexities of
friction, ratchets, and winches, the difference between
raising and lowering, and rope angles. For example, the
forces on a typical 3:1 system are much different when raising
than when lowering (when the "ratchet" Prusik holds the
load).
Although vRigger cannot solve every system, it
can solve amazingly complicated systems (click
here to see a large, and impractical,
example).
