Cross Haul

- Sometimes a cross haul is what is required. In this video, the rescuer and patient could not touch the ground. The patient started on the far side of the Sea Can and had to be lowered to the ground on the outside of the near Sea Can (not in the middle). Basically a raise, cross haul and then lower in 50 minutes.
I am not sure why it is being done this way. This is not a recommended method due to the extreme load being placed on the ropes due to haul angles and there is no redundancy if any of the lines break there will be a huge swing fall.
Hello Jay, I don't see anything wrong with this. Looks to me they are using a TTRSystem, so there is redundancy. The angles are not that bad (seem to be going from 120 to 150-ish), and up to 160 is okay if you think about it. What would you propose? Using a tension line reeve system? Then you get the same or even bigger angles. And the edge transition will be even harder as well. K I S S is always a good idea if you know what you are doing😉
@@TheRopeAccessChannel Thx for the reply. I do not see the redundancy. I only see one line which if it breaks the load will fall. I see no safety line. Thx J. When I teach this we have a seperate line that acts as safety if mainline breaks.
@@jayjamali2485 I just realized your comment was already a year old. I see four ropes in play, two from each side. It looks like a cross haul with a twin tension on both sides. All ropes seem to be loaded.
I completely agree with you that if it is one rope to each side that we are not seeing a best practice example. If it’s doubled up it’s a good setup.
