You mentioned attaching a rappelling rope to the hoist hook, without trying to offend, I would suggest this is a habit you should re consider. The company I work for in Oz used to do this, as did several others, until we attended a Breeze Hoist Users conference in the US several years ago. Breeze informed us that this habit can cause shock loading of the cable, and as a result the strength of the hoist cable is compromised. I recal there was an incident a number of years ago in Isreal where some one was killed after the cable broke. We ceased this habit as a result. Without telling you how to do your job, I would suggest a call to Breeze asking for Mike Mitchell might be advised.
Safe hoisting!
