Some nice tips to getting experience and actual handling!
.
i think another tip to play with / get experience in less critical situations is rigging take down into soft dirt.
>>allow dirt to take about 400# hit from 400-600# log, that ground control just doesn't let accelerate , not really catches full force; can work on that separately!
We have many times had truck pull lift a load back into position to drop again; very helpful to be able to do impossible in real world : have same size, drop, weight,rig and only vary technique and experience over several tries
>>should look to 'harvest' these opportunities when present and quickly play out; shows how relevant this is to groundies to even take time to know!!
.
In actual use would work to take as much hit as possible off the line; before handing to the system initially
>>pre-tighten (even if to allow controlled run later) as mentioned
>>if any friction points in system (branch not pulley as re-direct etc.) pre-tighten on either side of them and back thru
>>sweat/swig line hard to raise tension in section, then take 'purchase' thru 'bitts' of frictions
>>if overhead rig can hitch load out from cut and use load tipping down to help pre-tighten
>>if rig point under load; make hitch points as close as possible
.
Inversion of vertical load to rig point under ; if load not too long , can rotate still hinged pretty far, sometimes even re-tighten line some before tear-off of hinge for least rope impact.
.
For a partial friction redirect, i used to have a large aluminum clevis i ground numbers off (under water not to lose temper); frictional re-direct gives less support loading; aluminum can get hot/dissipates heat very well
>>Climber can help pretighten by hanging on control side (no weight on lifeline as safety catch) and pull up on load side for 2xEffort + weight (x impacts given of each) against load and frictions;
Frictions buffer fighting purchase,but then helping hold any purchases taken!
>>with foot cam can impact leg lift to control side to double (but thru frictions), rather than arm lift to load side
.
Now, as far as friction force on Porty as a device;
more Turns does give longer frictional path, but this is only the nominal change.
>> the force wants to take the minimal path of least loading : a straight line
>>view as on curve this as a 180 degree wrap, another folds the force back against self in this linear visualization.
So, simple,single Turn is minimal friction against host mount 180degrees; only bight of Turn gets intense contact.
>>vs. RT RoundTurn / Real Turn that has 3 180's and a game changer of force against itself as grips host mount.
>>This is the difference felt educate eye to see; more turns putting stop to even largest loads too easily..
.
Thus, on a winch, would never have load pulling right on the cable to spool connection
>>Would not even do any real loading pull with a simple Single Turn before cable connection
>>Would prefer not to even trust RT to this
>>Would prefer allow load pull to get thru cable to spool connection after at least Dbl.RT; so no real loaded pull on connection!
Turn passes force w/some reduction, RT is real reducer, Dbl.RT(5 180's or more) can seize easily on many loads/need real loading to relief to not have possibly dangerous sudden impact stop loading
