FAQs

Here are some of the frequently Asked Questions about our equipment. Hopefully this will answer most of your concerns.

If there are still things that you feel you would like to know, please get in touch and we will do our best to provide an answer.

Tripods

For assembly, how many people and how long does it take to erect? 

The individual components are all quite light and a single person can easily assemble the rig on the floor. Once assembled, you will need a minimum of 3 ( preferably 4 for the 7.5mtr ) persons to stand it up.  If you see our Portable Aerial Rigs there is a sequence of pictures showing a 7.5mtr rig being assembled and erected. Although there are 6 people in some of the pics, only 3 are actually involved in standing the rig up. With a little practice, the 7.5 mtr rig will be up and useable in around 20mins.

Of the "further options" list offered for the rigs on the website, is everything required? 

This rather depends on what equipment you already have and this list is really to make you think about what you might need. Some customers already have carabiners/ropes/shackles/pulleys etc, whereas others would like a complete new kit. The only “extra” that should be carefully considered is whether you will need the extra zinc undercoat if the rig is going to spend long periods of time exposed to the elements. If the intention is to only use this rig inside, or at events where it is erected and dismantled immediately after use then you probably do not need this option.

Do you need any additional equipment to erect the rig? 

The only tool you will need is a 19mm spanner. An ordinary 19mm spanner will do the job, but we recommend that you purchase a 19mm ratchet ring spanner from a local Halfords (or similar) as the ratchet facility makes the whole job much easier.

What is the breaking limit or safe working limit of these rigs?

Originally this rig was conceived and designed as being for single person use, but it rapidly became apparent that performers wanted to use it for duo acts. The original test load that we set was 900kgs and the rig proved itself able to cope with that comfortably, offering a significant safety margin for single person use with an average performer weight of 65-70kgs. We knew that at that load, the rig was nowhere near its capacity and we have now had a professional test house conduct further tests on our rig with a view to rating it for duo use. Our aim was to prove that our rigs could comply with the statutory 8:1 safety ratio for devices supporting people. So, we wanted a minimum of  2 x 70kg people multiplied by 8 = 1120kgs. We used a 7.5 mtr version ( shorter rig options are actually stronger) and increased the static test load applied by the test engineer until we had comprehensively passed our target without any damage to the rig. We are therefore able to confidently offer these rigs with a safe WLL of 150kgs, secure in the knowledge that we have still not reached the ultimate load that this rig will take. You can rest assured that it will cope with duo acts without a problem. Each rig has a serial number and WLL plate, with all details retained on our database.

Is this just single point or could you rig a double point trapeze? 

Several of our customers use this rig for static trapeze (We do not recommend it for swing trapeze). We can manufacture and supply a “spreader bar” that will allow you to hang a trapeze bar beneath it and use 2 strops above to converge on the central hang point of the rig. All we need is the width of your trapeze bar so that we ensure your ropes hang vertically.

Completely folded down and packed away what is the length?

We can supply a storage transport bag for our rigs to contain all of the components for a 7.5 mtr version. The individual leg sections on our rigs are manufactured at 2.5mtrs long.  These heavy duty vinyl bags are approx 2.9mtrs long with full length zips and carry handles, with a height of approx 40cms and a width of 30cms. A full 7.5 mtr rig weighs approx 75kgs.

How long does building take from ordering?

We are currently trying to keep the lead time to 10 working days from receipt of order & deposit. Because we manufacture all of the components here, the lead time is entirely dependent upon the level of orders. But we do treat all orders in strict chronological order.

Do you require full payment in advance? 

Not necessarily, we do ask for a minimum 50% deposit with your order or you can make a full payment up front. Should you choose the 50% deposit option the outstanding balance must be paid before the rig can be dispatched or collected. We can only accept cash or bank transfer payments – no cheques or card payments. 

Do you offer hire? 

Again a question that we are often asked. Currently we do not offer any of our equipment for hire, although there would appear to be a reasonable interest in that possibility. There are reasons. How much would we charge? Ideally we would need a substantial deposit to cover damage or even theft, plus a hire rate that made it attractive to customers, but financially viable for Circuspex. These rigs are quite robust, as they need to be, but we have to consider the safety of all those who would use a hire rig and our responsibility for their safety. Once out of our control we will never know what they may be used for, or what stresses may be applied beyond the design limits. It would be very difficult to guarantee the ongoing integrity of a hire rig as it may have been weakened by abuse, although not visibly damaged. We take the view that individuals will take a great deal more care when the rig is their own, as it is their own safety which is at stake. It is possible that we will re-visit this in the future, but currently we have no plans in this area.

Do these rigs require any maintenance? What should I look out for?

The design and construction of these rigs is such that they are virtually maintenance free. However, as with any piece of equipment that is supporting a person at height, it should never be taken for granted that everything is OK. Whenever the rig is assembled or dismantled, make part of that operation the visual inspection of each and every component for any signs of damage, and if an any doubt get it checked, or get in touch with us (a photograph by e-mail would be a good first step) and we will reply as soon as possible with our opinion. If a part is obviously physically damaged or deformed, we do not recommend attempting a repair. If a section is bent and then straightened it is far weaker than it is designed to be. Part of the original design brief was that all parts must be interchangeable, so we can provide you with a safe reliable replacement within a couple of days. The only “maintenance” that we suggest is to wipe any moisture from the rig before storing, and a short squirt of light oil (WD40) into any open ends of tubes occasionally. This is to protect the steel from corrosion as the coating process cannot penetrate into the small diameter tubes of the leg sections. Equipment such as this should be inspected on a regular basis and many performance venues insist on a current “safety certificate”.  If you cannot find this service locally, we can offer an independent, professional  engineer to carry out a check and issue certification for you. If you require this service. P.O.A.

Home Stand Single Arm

What height are they?

These simple rigs should be considered ONLY for basic moves and training at home and as such are designed to fit beneath the average ceiling height of 2.5 mtrs ( if you give us the exact height of your ceiling we can manufacture your Homestand to be as high as it can be ).

Can I do advanced shapes on a Home stand?

This rig simply allows performers to try basic moves and shapes in the privacy and comfort of their home, without having to arrange for a large eyebolt in the ceiling. The single arm does limit complete 360 degree spins with limbs outstretched, but will allow the user to get “comfortable” with their hoop and gain confidence at low level and with the feel of a hoop.

Home Rig Type B

What is it and what can I use it for?

It is a step up from the Homestand, and designed for heavier use. Our standard unit is now just under 3mtrs high and would probably be used outside or in garage or gym setting.  If you have a specific height in mind to fit under a ceiling height we can adjust the legs to suit. A second set of legs can be ordered to allow use at either height. P.O.A. Please note we will not manufacture this unit to exceed 3mtrs overall height for safety and stability reasons.

How many people will it support?

This rig has a stiffened top beam which is 2.5mtrs long capable of taking 2 people at a time on hoop or static trapeze. Because it can take 2, it is ideal for clubs/schools/training/festivals, in fact anywhere where there is a demand for multiple users to be able to “try” aerial. Simply throw a strop over the beam and attach the hoop /trapeze etc with a carabiner. It is light weight and easy to assemble without tools and at only 2.5mtrs long will fit in a van or on a sturdy roof rack.

Aerial Hoops

What size tube are these made from? What sizes do you stock?

We manufacture all of our hoops in our own workshops from 27mm diameter steel tube as standard. But, if you have smaller hands, we can produce them from 22mm solid bar at the same price (availability might take a day or so longer). We are able to roll any size to suit your needs up to 110cm diameter at the fixed price. Larger sizes of hoop and different sizes of tube can be rolled (we can roll up to 90mm diameter tube) , please call us for a price if you need something special.

How do I know what size tube I need?

If you are working with an instructor they may be able to advise you, or if you can try out hoops that other people have that would be a good guide. There are differing methods of working out your hoop size, but they all arrive at a similar answer. Probably the simplest is to sit on the floor and place your fist on top of your head with your thumb against the crown of your scalp. Now measure, from the floor to the top of your clenched fist. Well actually! get someone else to measure, because you might find that a bit tricky.

Are the hoops tested?

Yes. Each hoop is subjected to a static load of 500kgs after manufacture and a test certificate is issued with the serial number of the hoop. (each hoop has a unique number stamped on the hanging point).

Do the hoops have grip tape on them?

No. Some people prefer to apply their own choice of grip tape in their own way, so we leave ours untaped. We do supply our hoops with a powder coat finish in black, white, blue or green as standard. Other colours are available, but there will be a small additional cost if you want a specific colour. Feedback from some of our customers is that the powder coat finish actually offers very good grip, unless your hands start to sweat. Some find that rosin solves that problem, although in time this will probably wear through the coating. At which point, you can simply apply the good old grip tape, so there is nothing lost in trying it without tape initially.
