Mobile hoist arm/Gantry Ideas 50L

Unread postby roomfullofmirrors » Sun Mar 11, 2018 1:33 am

I need some ideas for a mobile/portable hoist arm or gantry setup for lifting the 50L malt pipe.
Have an electric winch, but I want to be able to set up in a number of locations i.e. no fixed brew space - yet!

Is anyone already using something that fits the description? I had a look at Royco's stand and Gantry viewtopic.php?f=6&t=585&p=5704&hilit=gantry#p5704 post - which looks like a winner. I brew on a stainless table with castors which means i can wheel the BM out from under the malt pipe if necessary.

If you've got some ideas (and pics) I'd really love to see them!

Cheers :cheers:

How collapsible does it need to be for storage?
How quick do you want it to build?

Mashy, I'd like to able to fit it in the back of my ute tray and lift and move it on my own. If it breaks down into a few pieces thats better than one heavy item.
No urgent time frame for this, but sooner rather than later to make brewing easier.
Do you have ideas?

For something portable you have two basic designs.

Something that looks like a coat rail:

This design does get messy getting over the table.

So a simgle arm, like and engine hoist.

If you already have a table, why not fabricate a simple upside down 'L' ... 2 bolts and clip the hoist on it.

20kg would not be a big lift for SS box (provided you stiffen the corner)

Have you go a pic of the table? And where do you want the malt tube to go once it is lifted?


EDIT: Just found this. http://www.homemadetools.net/forum/%91o ... table-6318 - scroll down to post#4

Now imagine it is SS and light weight. It will need a counterbalance though.

If you wonder why I am putting in so much effort I am thinking about a brew table for myself...which includes extraction.

Yup I like the 'Ultimate BIAB rig'

I think it would be better if you attached it like a fifth leg in the middle of a short side of the table. More stable.

A really easy solution is one of these. https://s7g3.scene7.com/is/image//ae235 ... ageMedium$
When you are ready you stand on it - beside the BM. Still means you have a 15-20kg lift, but the angles are better.

Big question is what do you with it once you have lifted it out?

Nice one.

What do you think the max weight of a BM50 full malt tube is?

Never measured it but that would be intesresting to know.

To my knowedge, the full malt tube volume is approx 30L, usually including 10+kg malt. You have quite a bit of succion on the first pull. As per Beersmith data, the water absorption by grain is 0.652 l/kg, so 10kg of drained malt, but wet, should be about 16kg.
I would say at worse 30-40kg at the immediate "takeoff" due to succion, then reducing immediately to a good 25kg, finally slowly reducing while draining. Again, just thoughts and rought estimate, no hard data.

I have tested my winch (200kg max) and coat rail style structure at 100kg to be safe.

Hadn't thought about takeoff - good point.

That is fantastic! You really have some mods going on!
Where did you get the customised thermo-sleeve? Great logo too!

Do you brew commercially?

Nice set-up, Sladek789 :wink:

It is the stantard BM sleeve (link below) where I removed all Speidel stickers and added mine. It is not cheap for sure but it fits perfectly the handles, tap,..

Nope but I like to do things well...too much if you ask my wife :-) I like to say that I professionally homebrew :beerbang:

You should see the rest... #equipementporn ! :-) No excuse to make bad beers!
BM front view, since the pic I put back the front tap to serve as a backup tap and to easily pour samples. Added a handle to the BM hood. I also customed the bottom drain output with a T fitting to fix pump and use it for whirlpooling and transfer to fermenter. And kept a drain output for cleaning.

Nice, did you drill a new hole for the bottom exit?

No drilling, the drain hole was made by Speidel.

I had some rust issue with the first BM I received and I sent it back. I received a new one (not the PLUS version) but with an extra drain tap at the bottom, like on the PLUS version.
Very happy about it, it greatly helps for cleaning.

No need to drill you can re-pipe the a pump fitting.
