A part of the training culminates in a competition wherein teams of eight jrotc cadets must cross an obstacle using one rope and only the first and last cadets are allowed to touch the obstacle.
One rope bridge.
Rope bridge kits are intended to create a suspended passageway between two or more tree platforms but can also be used to span rivers and other obstacles.
The cables follow a shallow downward catenary arc which moves in response to dynamic loads on the.
Step by step instructions are included.
It is easily constructed using a single 120 foot rope.
If you have any questions please email us prior to ordering.
This competition requires the use of several knots in the construction of the rope bridge.
The simplest rope bridge consists of a cable to stand on and a cable to hold onto with your hands.
Regular kits are typically anywhere from 3 to 30 in length and use 3 8 cables for the.
The situation can be improved by offsetting the hand cable to one side which allows the walker to stand more vertically.

The rope is anchored with an anchor knot on the far side of the obstacle and is tied off at the near end with a tightening system.
They have no towers or piers.
The rest of the cadets must traverse on the rope bridge.
The rope is anchored at the far side of the obstacle with a round turn and two half hitches or with a bowline and is tied off at the near end with the transport tightening system.
This design is quick and easy to build but can be tricky to walk along.
The one rope bridge is constructed using a static rope.
