Here is a look at the river crossing before I started. It is a push out that the loggers made when the timber was cut years ago. The span is 45 feet.
First thing to do was drill and set poles for cable. Poles were 20 feet long and buried 6 feet in the ground and concreted.
Then you set the dead falls. Bottom cable dead falls are 5 feet long and buried with 200lbs of concrete each. The Top cable dead falls are 5ft screw in anchors.
Then you lock the poles together with 8 inch lag bolts, Drill through all for cable and level the ground to bridge level.
Then you pull the cables dead fall to one end and attaché the other to turn buckles for easy adjustment.
Bottom cable is ¾ in cable top cable is ½ guide wire terminating to a center support in the middle of the bridge.
Attach 4 by 4’s to cable with U bolts spaced at 20 inches apart. Notice that since I had ¾ cable left I put a cross cable in the middle of the bridge for added support to the lumber.
Then you mount your runners on and level the bridge.
Only thing left to do is test it out…
Tested it with almost 2000 pounds of weight and would only rock a bit.
Sweet victory…
