discomikey Posted July 11, 2012 Share Posted July 11, 2012 as per the title really, im ready to install my new toy (4 post ramp) and i need to get hold of 16x ground anchor (is that what theyre even called? like a rawl plug but stronger and for concrete. the hole diameter is 21mm so i assume that its a 20mm thread i need. any suggestions? cheers.

crclifford Posted July 11, 2012 Share Posted July 11, 2012 have you had a look at Hilti, they do a two part system that you drill in and then fix with a resin. They also do the types that will expand as well. Another make to try for the expanding plugs is Fischer, I've found their frame anchors to be bloody good. Link for Fischer.. http://apps.fischer.de/poc/default.aspx?page=details&layertype=Z&sprache=EN&kat=$MART-HK-$MKAT-HK-$MPG-SCHWERSTAHL-$MZG-F69&ekat=$EKAT-HK-EN HTH Quote Link to comment Share on other sites More sharing options...
Night Train Posted July 11, 2012 Share Posted July 11, 2012 I usually use rawl bolts. M20 ones would be very spendy! Quote Link to comment Share on other sites More sharing options...
discomikey Posted July 11, 2012 Author Share Posted July 11, 2012 ta night train. spendy they may be, but as thats the size of the holes in the bases of the towers, im guessing thats what i need for it to safely lift (its a 3.5tonner) with for some reason a max lift of 4 tonnes (depending on wheelbase) Quote Link to comment Share on other sites More sharing options...
Night Train Posted July 11, 2012 Share Posted July 11, 2012 I would say it is worth checking out the chemical bond ones as they will also require a smaller hole in the concrete. A 20mm bolt will probably have a 32mm hole for the anchor part. Maybe a M16 bolt? http://www.rawlplug.co.uk/index.php?option=com_content&task=view&id=20&Itemid=25 Quote Link to comment Share on other sites More sharing options...
bishbosh Posted July 11, 2012 Share Posted July 11, 2012 I would use resin anchors rather than mechanical expanding ones. They are much better at resisting cyclic loading. You can get them from screwfix. Quote Link to comment Share on other sites More sharing options...
task Posted July 11, 2012 Share Posted July 11, 2012 I've used both sorts when I worked down the mine, if you can afford them go for the resin ones. Quote Link to comment Share on other sites More sharing options...
Ridgeback Posted July 11, 2012 Share Posted July 11, 2012 The resin stuff is really good, I have used hilti cem fix when I worked in the entertainment industry, we used it for putting security bolts into walls and concrete ceilings that would act as a safety point to clip to when working at hight. They all got load tested and we never had one fail . Quote Link to comment Share on other sites More sharing options...
stuck Posted July 11, 2012 Share Posted July 11, 2012 Mikey, Are you in Longcliffe near Chesterfield? If so I may be able to help. Quote Link to comment Share on other sites More sharing options...
discomikey Posted July 11, 2012 Author Share Posted July 11, 2012 near chesterfield as in 20 miles away, then yes. how can you help? Quote Link to comment Share on other sites More sharing options...
simonr Posted July 11, 2012 Share Posted July 11, 2012 Glue bolts win every time for strength & longevity! If you were closer I'd lend you the kit - but Screwfix is your friend! My ramp is held down with M16 high tensile studding x 4 in each corner with Nyloc nuts and is solid as hell! Quote Link to comment Share on other sites More sharing options...
landy andy. Posted July 12, 2012 Share Posted July 12, 2012 Just make sure the holes are dry, and dust free, if using chemical ones Andy Quote Link to comment Share on other sites More sharing options...
ejparrott Posted July 12, 2012 Share Posted July 12, 2012 We use Resapol anchorgrout for fixing out machines down. I'd be tempted to phone the manufacturer and ask for the recommended fixings. It may be 21mm holes for M16 studs, to allow for variances in floor drillings. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted July 12, 2012 Share Posted July 12, 2012 (edited) I think this is the manual for your lift Mikey, only downside is it's in french everything but english http://transquip.co....al4000-7000.pdf Edited July 12, 2012 by CwazyWabbit Quote Link to comment Share on other sites More sharing options...
elbekko Posted July 12, 2012 Share Posted July 12, 2012 I think this is the manual for your lift Mikey, only downside is it's in french everything but english http://transquip.co....al4000-7000.pdf It doesn't mention anything about bolt sizes, but it does reference another manual "included with every lift". It does mention the bolts need to be torqued to 40-45 Nm. Quote Link to comment Share on other sites More sharing options...
discomikey Posted July 12, 2012 Author Share Posted July 12, 2012 cheers guys. local bolt/bearing suppliers had some m20 rawlbolts for £2.50 each obviously x16 then i went for resin aswell as the tube was £6 but then i had to spend £20 on a resin gun that ill probably never use again haha so all in all its totalled up to £66 which aint too bad i dont think. add that to the £600 for buying it, and around £60-70 to fetch it. and dads mcdonalds £6 so around £742 all in Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted July 12, 2012 Share Posted July 12, 2012 That's a bargain for what you have ended up with Quote Link to comment Share on other sites More sharing options...
discomikey Posted July 13, 2012 Author Share Posted July 13, 2012 isnt it just. in hindsight though wish id gone for m16. as getting all 4 bolt holes to line up perfectly with the holes in the posts is a nightmare because the holes are 21mm diameter and the bolts are m20. and apparently m16 is perfectly strong enough too. ahh well all 4 posts are secured now and ive just got to wait for dad to give me a hand with setting the bed right.
