If you are an aerialist (student or professional), it is frustrating existence forced to stay at abode due to the Covid-nineteen self-isolation.  You could be feeling your body become weaker past the day, and all you crave is to get upwardly on your aeriform gear and work out or train.  It is worse than if you lot've had an injury because the pain of the injury is motivation to stay inactive until you have recovered.  Without the states knowing when we volition be allowed to return to our training spaces, many circus students are because setting up their aerial gear at home.  This Web log is to advise and guide students who are making this decision, and so that they install it correctly so that they tin railroad train in rubber.  As an advanced rigger, I have needed to install many rigging systems at circus schools, dance studios, gyms, theatres, etc. and fifty-fifty at individual homes.  As a coach, I see how the students utilize these systems and the forces practical to that organization, so I believe that the data I can requite y'all here is relevant.

If you have a large enough garden to install a free-standing rig, yous are one of the lucky ones.  Most students don't take this luxury and need to rely on female parent nature to provide a large plenty tree with a potent plenty user-friendly co-operative on which they will hang their gear.  Ideally, a convenient branch will prepare your gear at least 1.5m (5ft) from the body or other branches.  What is the risk of hanging from your gear which information technology prepare in a tree and what kind of tree is potent enough to hang from?  Arborists propose that a slow growing tree (like oaks) have stronger branches.  The most obvious question should be: is the co-operative going to hold my weight?  What size branch will hold my weight, and volition it still hold me if I do dynamic loading on the gear I have hung from it?  Does the branch that you have called take a hidden weakness like forest rot, mould, fungi or was it once in a fire?  Since it is not possible to know this until it is too late (and you lot are on your way to a Covid-19 infected hospital), is this worth the adventure?  Are yous going to get injured climbing into the tree to hang and remove your gear to avoid exposure to bad atmospheric condition that could perish the material from which it is made?  Frustrated students might believe that it is worth the chance, then if you lot are going to hang your gear in a tree, choose a branch that is at the very least almost the size of your thigh.  Choose a soft sling that is rated to 1000 kgs and wrap protective material for both the sling and the tree before wrapping the sling around the co-operative.  The sling should be long enough to make a full circle around the co-operative.  If you "asphyxiate" the sling through its self, you will lose one-half the normal strength of that sling.  All slings should have a tag with its rating and expiry date, if there is no tag to give you this information, you should not use information technology.

In a normal circumstance at your grooming studio, a qualified rigger would accept installed rigging points from which y'all tin hang your gear.  These points should take a safe ratio of 10:1 which ways that a combined weight of the student plus the gear, multiplied by ten.  If the average weight of an aerialist plus their gear is 70 kgs (155 lbs), the rest of the system should exist able to have the weight of 700 kgs.  Some acts, similar straps, tin generate a much higher dynamic loading on a rigging system, and lately, circus studios and schools have had to re-evaluate their condom standards and increase the prophylactic ration to 15:one.  This should exist the case for not only the beam/truss that you are hanging off, but every piece of hardware that is part of that system, similar your gear, maillons, carabiners, shackles, cables, ropes and pulleys.  Information technology is hardly possible to copy an ideal studio style rigging at your dwelling.  If you are renting a dwelling, make sure your landlord has given their permission!  They might not and I know what you lot're thinking, "but who volition see?",  or "if that wooden beam tin can't hold my weight, how is information technology holding up the roof?".  This does non change the fact that yous want to – no you lot Need to train then desperately it's driving you crazy.  You're going to do it anyhow!  No one will intendance….until something breaks and you get injured and endeavour to make a claim on your home insurance policy.  If an insurance amanuensis visits your home to observe out how you received the injury (considering it is very unusual), and they encounter a DIY (Do It Yourself) rigging task, they will definitely non pay out.  Okay, that is the worst-example scenario and information technology might never happen.

Even though I practise not recommend rigging at home, I understand our current situation and will give you my advice to at least do the safest rigging chore possible.  In Australia, a human may not hang from any kind of wooden axle, but human safety is not taken that seriously in other countries and I respect that.  The facts are:- wooden roof beams are designed to agree the weight of the roof and possible solar panels and a wind loading, which are from above, but non designed to hold a 'point load' of another 700 – 1000 kilograms hanging below it.  If you have open up roof beams, this makes life easier and yous do not demand to go rummaging through a human foot of insulation and risk falling through a ceiling panel.  Y'all will need a long enough rigging bar to share the load over a few beams, preferably four beams.  That might need a very long piece and therefore, too difficult to get into a roof cavity.  At the very least, share the load over 2 beams (with at to the lowest degree a foot of rigging bar extending over either side of the wooden beams), and as shut to a beam support (wall) as possible.  The rigging bar should exist a length of square mild steel tube, not wood. The minimum exterior bore of the mild steel square tube should be ii inches, if the wall thickness is no smaller than 1/8 inch.  I adopt the three-inch pipe with a 1/4 inch wall.  Brand sure the rigging bar is strapped or tied downward very well to the axle to avoid it moving during use.  Small half ton necktie down ratchets are practiced for this purpose, wrapped in a "U" design and an "X" blueprint over both sides of the rigging bar and wooden beam.

About abode have ceilings, and then if you have a ceiling panel between your gear and the rigging bar, I recommend that yous remove the whole panel.  This will requite you easier access to the roof crenel during the installation of the rigging bar.   You lot can supervene upon the ceiling console, undamaged, when you can remove your dwelling rigging bar.  This also gives you the opportunity to continually check your rigging bar to brand certain it did not bend nether load or motion along the beams unevenly.  If yous cannot remove a ceiling panel and demand to make a large pigsty in information technology for the chief hanging sling, measure the get out point very well and get out plenty infinite around the sling to avoid breaking more of console due to unexpected sideways move.  You will need to do a visual check of the rigging bar after using is for the first time (and weekly), to make sure it is still tightly in place.  Avert doing any dynamic tempos or drops on your habitation system, only do static skills and strength preparation.  If yous hear sounds of the wooden beams "groaning" or "squeaking", the chances are that you have over-loaded the wooden beams and you should abandon using those beams or that identify for your grooming.  My final piece of advice is that if at any time you are in dubiety, do not use information technology.  Check everything over again, or take a picture of your rigging and send information technology to myself or another qualified rigger to become their guidance earlier loading the rigging bar.  Prophylactic home rigging and safe preparation.
