mbthegreat Posted March 2, 2008 Share Posted March 2, 2008 I'm currently looking at specing some new profiles for my Amdram place, but space between the bar the the roof beam just behind it is quite limited, so I'm trying to find out the measurements for the lanterns I'm looking at. So far I have been unable to find the distance between the yoke and the very rear of a Selecon Acclaim Axial (18-34), the spec sheet (see here (warning, pdf)) doesn't have the measurement, and I was just wondering if anyone knew, or had one to hand that they could very kindly measure for me. Thanks. Link to comment Share on other sites More sharing options...

Thanks. KAVE stock a large number of selecon acclaims, google them, then ask. alternatively, both sparkyweb and Dave Singleton are employees of kave on here.

the kid Posted March 2, 2008 Share Posted March 2, 2008 I can't do it right now I can tomorrow when at work. If its any help right now I know its less than 30cm. Link to comment Share on other sites More sharing options...
GridGirl Posted March 2, 2008 Share Posted March 2, 2008 I'm pretty sure (can't check as we don't have any of the axial zoomies, just the regular ones) that the yoke is fully adjustable and you can put it behind the gate if you want to - it looks like it in the picture in that PDF file. You certainly can on the regular zoomspots; it does mean that the lantern is a bit unbalanced (nose-heavy) but provided you lock it off solidly it's fine. Selecon's Pacifics are also relatively short between yoke and the back end of the lantern if you're looking for other options. Link to comment Share on other sites More sharing options...
mbthegreat Posted March 2, 2008 Author Share Posted March 2, 2008 If it's less than 30cm, it should be fine. We have 36cm between the bar and the roof beam behind it. Thanks for the help. Link to comment Share on other sites More sharing options...
boatman Posted March 2, 2008 Share Posted March 2, 2008 You can get the four page user manual (574KB pdf) from here. To quote from page 2: Adjustable Yoke Adjustable yoke – The position of the yoke can be altered to anywhere along the length of the luminaire lamphouse.To move the yoke, loosen off the T-locking tilt handle and the M8 nylock nut on the opposite side. Also loosen the 2screws on the Yoke locking disc on the handle side of the luminaire. Slide the yoke to the desired position andtighten the M8 nut, screws and T-handle taking care to check that they are opposite each other.

mbthegreat Posted March 2, 2008 Author Share Posted March 2, 2008 Thanks, didn't spot that, was just skimming the manual for measurements. Link to comment Share on other sites More sharing options...
boatman Posted March 2, 2008 Share Posted March 2, 2008 How is your bar mounted? If it's suspended from studs as ours are, then you'll have a lot of problems if the yoke isn't immediately above the COG of the lanterns as the bars will twist.

mbthegreat Posted March 3, 2008 Author Share Posted March 3, 2008 It's not actually a bar, I believe the stuff is called dexian, so I don't think this should be an issue. Link to comment Share on other sites More sharing options...
Ynot Posted March 3, 2008 Share Posted March 3, 2008 It's not actually a bar, I believe the stuff is called dexian, so I don't think this should be an issue.Dexian?Steel angle? Hmmm.... Wouldn't say for sure, but not sure how this would handle the weight of a profile - may be OK for a while, but I suspect it may well bend a little over time.Not really what Dexian was made for... How is it secured to the roof/grid/ceiling? Link to comment Share on other sites More sharing options...
peternewman Posted March 3, 2008 Share Posted March 3, 2008 It's not actually a bar, I believe the stuff is called dexianYou aren't thinking of Unistrut instead are you, which is a U shaped channel, and probably more likely to be used for similar jobs.

mbthegreat Posted March 3, 2008 Author Share Posted March 3, 2008 It may be that, it certainly has U-Shaped slot. As for attachement to the ceiling it seems secure, and shows no sign of bending. Link to comment Share on other sites More sharing options...
the kid Posted March 3, 2008 Share Posted March 3, 2008 I make from the yoke to the very rear ( the handle) a smidge under 30cm Link to comment Share on other sites More sharing options...
Don Allen Posted March 3, 2008 Share Posted March 3, 2008 There is a drawing of the Acclaim Axial on their websiteProductReferenceResource try to keep the yoke at the centre of gravity to make focussing easier. The Acclaim have a good tilt lock but over a period of time it might not last if the centre of gravity is too far out. The early CCT profiles and Selecon profiles were painful to work with due to the yoke being located at the rear of the unit. Dexion is angle steel that has lots of holes along it's length and would twist with unbalaned lights hanging off it. Unistrut is box shape with a slot along one side that is heavier duty, but with unbalanced yokes, make sure the unistrut is mounted securely.
