Below is an example of some of the kind of structures that can be created for each end of your zip wire, the designs can be quite varied as the only real
requirements is strength (so it does'nt move under the high tension required) and safe (no obstacles that could injury the user).
The other feature that can be useful is having the ability to increase or decrease the height of the cable, this gives greatest flexibilty to achieve a safe
speed and a safe fall height.
