Could anyone show me what the rules are regarding 3.0m lifts on TG20 please? I know pavement lifts are their own class, minimum 5 boards wide etc but not sure about 3m lifts.

Does the Eguide assume EVERY lift will be 3.0m?.. Can we not have a custom 3m + 2m on top for example?

Last question, What's the guidance on rakers having ground anchors?

Not a lot of info regarding these so any help or source material appreciated.

Thanks all
 
The TG20 eguide does not allow you to mix 2 and 3m lifts however, you can build lifts to a maximum of 3m high under TG20. In theory you could build lifts of any height up to a maximum of 3m, so long as you have selected 3m lifts when producing your compliance sheet. If you only select 2m lifts, the maximum height of each lift can only be 2m.

With regards to Rakers and ground anchors, Sect. 6.23 of the TG20:21 Operational Guide has the following guidance.
Rakers MUST be suitably restrained at the base. The operative word here is "MUST". It then goes on to say how this may be achieved, including driving a tube into the ground and connecting the raker to it it with a longditudinal tube all fixed with load bearing fittings. How you actually stop the raker from slipping is up to you, so long as it is safe and does not pose a hazard to anyone. I see many rakers supported with a butt tube at the bottom fixed only with clips. This is clearly wrong as clips are not load bearing fittings.

TG20 eguide is limited in it's information. For more in depth information, you need to obtain a copy of the TG20 Operational Guide.

Morning bud, we'll rule goes maximum unsupported leg (node point) ledger structural transom are connected to the upright....shouldn't exceed 2.7m which is roughly 150mm under 9ft...but if you are required to have a boarded out scaffold lift every 3m, you will have to have a Skelton lift at 2m levels above each boarded level...then a 1m above that to your working lift, so basically you can have your 3m lifts but you will have a 2m lift then 1m void with ledger to ledger brace with a plan brace through the length of the elevations...I've done it..4yr ago... if I remember right it was 20 + lifts / Floors each working in roughly with the concrete slab heights..Students accommodation "Bridle Works" Glasgow...Cathedral St / Hanover St.

Also on the rakers, I personally would class this method as a temporary structure support...I would prefer to use a buttress braces/ wing brace, butting off the facade..stop the scaffold falling in, however I wouldn't recommend driving a 3ft tube at 35 degrees angle away from the structure into the ground in case of contact Under ground services...Put kentledge at the base of your rakers ( 10 x 10ft tube bundled 300lb ) come off your rakers with 3ft tube with a double to form a cross ( like a picnic bench base ) run a ledger underneath the two doubles connecting the two rakers and load it up with your tube...buy the way what is it your building, it will have to be a design drawing....

That's a 2.7m pavement lift mate. 3.0m lifts are available but not much guidance on them.
 
Layman's terms ( 2.44 max unsupported leg) means nuffn on that standard until 2.44m ie your first Double either it being the underside of an Aberdeen (structural transom) or you lift ledger...
You only have the basewood / baseplate your standard covered in public safety foam

BRILLIANT ;)👏 NOW your reading the SG : scaffold guide to scaffolding instead of asking for Answers...being lazy... when they are in the booklet you got from CITB / NASC...and what you don't know or get in the booklets...seek TG technical Guide ...PS what dose it say about
2.44m maximum, to lazy to look...😆 don't know why I have 2.7 and 2.4 in my head 36yrs of scaffolding does your head in! ...anyway always remember smaller is better ... bay and height 💪
