Tube motor roller shutter door

[rob h]

I’ve just been getting quotes for a new roller door it’s for the grain pit so only used when the dryer is running.its rough 4.5 m square.one quote they want to fit a single phase tube motor as its not going to be used often. so would we be ok or do I get a quote for a 3phase .i have a price from another company and the want to fit 3phase geared motor but it’s a lot more money

I’ve got 3 tubular motors I believe they are all ellard but I over sized them (at the recommendation of the supplier rh shutters in leeds) for the job so they are on top of it. All been in use one daily’s others prob slightly less for few years no issues yet.

biggest is a 12ft square door which I converted from 3 phase it’s an oldheavy bugger and the dude made my up a new tube with motor in it and I swapped curtain over. Think it was about 350 inc vat with controller and remotes etc

Do the tube motors have a brake in them?

Yes .is that a good thing

 

[Netherfield]

Yes, you need something to stop the door from trying to unroll it self while open, a good heavy door can come down at some speed, from height, you wouldn't want to be underneath it, it can also do a lot of damage to the slats if not controlled on descent.

My thinking is there will be a more chance for a bigger brake setup on a geared motor.

Ask yourself which is easier to repair.

over a grand difference in price. just makes me think .although they are quotes from different places
