Running Skyline

Assumptions:

 

•The haulback line is also used as the skyline, that is the carriage rides on the haulback line.

•Maximum allowable tensions in the haulback line are the minimum of either the maximum safe working load or the maximum tension that can be generated by the hauler power-train when the carriage is above the terrain point being examined.  Maximum torque provided by the power-train is specified by the user.

•Maximum allowable tensions in the haulback line are used first in the calculations.  Tension in the mainline is then checked to see if the maximum allowable tension required in this line to achieve static equilibrium is exceeded.  If the mainline  tension is exceeded the haulback tension is reduced until all line tensions are within maximum allowable tensions.
