Cable Analysis : Softree Technical Systems Support

 · The Cable Analysis function group calculates the behaviour of cable-yarding systems. You provide a ground profile, logging setup (cable configuration, working tensions, and weight as well as carriage weight) and a calculation type. You can then display graphic or tabular results including tensions, load capabilities and ground clearance.
