Rope access and high angle rescue reference book and visual materials. Free version.

Current contents:
- Mechanical advantage systems reference book;
- Deviation simulator. Shows value and direction of the force acting on the deviation depending on the rope angle and load;
- Y-hang simulator. Shows acting forces depending on configuration of attachment and load.

In Pro version:
- Mechanical advantage systems builder. Allows to construct mechanical advantage systems used in rope access and high angle rescue. Builder allows to analyse gain, friction loss, devices and anchor loads;
- Tyrolean simulation. Allows to estimate acting forces depending on the rope sag and load.

Application is being extended by free updates.
