Rope Rescue Over a Bridge Using an Aerial Ladder Truck as a High Point
Features force vector analysis of different configurations & in-depth look at the CMC Lifesaver Seat & Chest harness.
*Single working line w/ a very limited belay line that serves primarily as an offsetting/vectoring line.
Key Considerations:
1) Critical point at the tip of the aerial
2) Swing fall of the belay/vector line when arresting fall due to failure of aerial
3) Clearance above the ground to allow swing fall to pendulum in space without the load hitting anything

Corrections: The horizontal aid kit shown is flawed in that there is only a single connector between the technician's harness and the anchor system once the ascending kit component is removed to progress (even though connected at two anchor points at all times). Therefore a simple solution is to wrap a 7mm VT Prusik around the fixed portion of the Progress Adjust-Y lanyard in a 4-on-3 configura...

Low Angle Rope Rescue: An Oxymoron?
Переглядів 1,8 тис.6 місяців тому
One thing I didn’t mention was the option for “role reversal” between a rope system and the rescuers: A single rope could also act as a working line that is either raising or lowering the litter, while the tenders serve as a backup to hold the litter in place off the ground.
Mechanical Advantage: Pulley System Principles
Переглядів 1,2 тис.6 місяців тому
A note about the size of the pulley sheave & it's effect on efficiency: A larger ratio between the sheave diameter vs. the rope diameter will increase rope strength, but does not necessarily, nor directly affect the pulley efficiency. What affects the pulley efficiency are two things: 1. The coefficient of friction between the bearings/bushing and the axle 2. The difference in diameters between...
