0 kpu121265 Posted February 8, 2011 Share Posted February 8, 2011 You getting 'close'? Sorry, can't actually answer the question. Regards Ken Quote Link to comment Share on other sites More sharing options...
0 mike65 Posted February 8, 2011 Share Posted February 8, 2011 Do you want the simple answer or the complicated one. It all depends on the number of axles and a few other factors Non driven axles are 10,000 KG Driven axles generally 11,500 KG 5 axle tractor trailer combination 40,000 KG 6 axle tractor trailer combination 41,000 or 44,000 KG (not sure why 2) CAn go more but then you are into specialist stuff and even more pound signs flash before your eyes.

0 Degsy Posted February 8, 2011 Share Posted February 8, 2011 Richard, the max load weight obviously depends on the tare weight of the outfit. If it is plated for 44 tonnes gross it would probably be able to carry a load in the region of 28 tonnes. Above this as Mike says you get into STGO territory and can go to much greater weights but of course with a lot more axles. Quote Link to comment Share on other sites More sharing options...
0 R Cubed Posted February 8, 2011 Author Share Posted February 8, 2011 So if you had a 2 axle tractor unit and 3 axle trailer what would the un-laiden weight be roughly, what could it carry ? What about a 3 axle tractor unit and 3 axle trailer what would the un-laiden weight be roughly and what could it carry ? Is there a max length for a trailer ? Is there a max height of load, obviously to miss bridges but what is it ? Quote Link to comment Share on other sites More sharing options...
0 mike65 Posted February 8, 2011 Share Posted February 8, 2011 I have assumed you are refering to the everyday run of the mill truck. So if you had a 2 axle tractor unit and 3 axle trailer what would the un-laiden weight be roughly, what could it carry ? No idea on umladen weight would depend on tractor and trailer. (Never hand to design for unladen) Max fully laden weight would be 40,000 KG (dependant upon wheels/tyres etc). The load on the drive axle cannot exceeed 11,500 KG What about a 3 axle tractor unit and 3 axle trailer what would the un-laiden weight be roughly and what could it carry ? No idea on umladen weight would depend on tractor and trailer. Max fully laden weight would be 44,000 KG (dependant upon wheels/tyres etc). Is there a max length for a trailer ? Max artic length is 16.5m (tractor and trailer) MAx trailer length is 12.2m from the kingpin (5th wheel) STGO with rear steer can be longer. Have recently looked at turning room for a 26m o/a length. Is there a max height of load, obviously to miss bridges but what is it ? In the UK their is no height restriction but you may need to check your route very carefully. You have not gone and bought a boat, I belive there was a surplus aircraft carrier down your way. Mike Quote Link to comment Share on other sites More sharing options...

Richard, this is all from memory and it's not that good so I stand to be corrected but 5 axles (tri axle trailer) gross would be 38 tonnes, tare around 14 tonnes so load approx 24 tonnes. As I said before 6 axles gross 44 tonnes, tare around 16 tonnes so load approx 28 tonnes. Can't remember what the metric length is but used to be 40ft but there is an exception allowed to increase slightly to carry standard pallets. Never looked into max load height, for normal running we always used to measure height , making sure it was well under 16 ft as that is the standard clearance on bridges, cables etc or it was in my day. Best I can do for you off the top of my head but no doubt someone will post a link for up to date regs. Quote Link to comment Share on other sites More sharing options...

What about a 3 axle tractor unit and 3 axle trailer what would the un-laiden weight be roughly and what could it carry ? Is there a max length for a trailer ? Is there a max height of load, obviously to miss bridges but what is it ? road bridges have there height marked if they are under 16 ft so if not marked they must be 16ft or over so 16ft must be the standard height for major road bridges , it is an offence if you dont know your vehicle height which must be clearly displayed in the vehicle . blackwall tunnel has a 15ft 6in clearance southbound and 13 ft clearance northbound so allways check bridge clearances with your load . i drive an 8 wheel grab lorry and a 6 wheel plant lorry so i look out for bridges all the time even when driving my land rover i pull over to the middle of the road and look in the mirror for the crane which is not there ! then look at the puzzeled look of the oncoming motorists who wonder why iam driving down the middle of the road :nut: Quote Link to comment Share on other sites More sharing options...
0 N.O.S. Posted February 8, 2011 Share Posted February 8, 2011 And the answer to the question you didn't ask, but need to know, is (): Yes it is relatively cheap to haul anything under 27 tonnes and less than 13 ft tall / 9 ft wide. This would be using a tri-axle stepframe trailer with a bed about 3 ft off the ground. Anything wider or lower or heavier will start costing telephone numbers or very large favours! Has anyone else noticed the exponential increase in stepframe population over the last 25 years? Whatever did we do before they were around in such quantity?

0 Panzer nut Posted February 9, 2011 Share Posted February 9, 2011 Question arises is that why do you not check the vehicle data plates and manuals for the information? searching on the internet would have got you the answers far quicker and in a less protracted way. Needless to say i still read the thread..lol Jon Quote Link to comment Share on other sites More sharing options...
0 Dougy FV432 Posted February 12, 2011 Share Posted February 12, 2011 An average tri-axle tractor unit will weight in about 8tons and a decent tri-axle step frame trailer (see forsale section, mine is up for grabs) come in at approx 10tons. I could easily carry a fv432 (13tons), lightweight and sankey trailer. Max height is governered by motorway bridges as they are 16', if of motorway you have to plan as bridge heights can anything.

Mike Unless "The Traffic Officer's Companion" is wrong again, then,Maximum length of 16.5m. is for semi trailer that is "not a low loader" or "is a low loader built before 1/4/91" Maximum length for an articulated vehicle where the semi-trailer "is a low loader manufactured on or after 1/4/91 " Max length becomes 18m.

Best I can do for you off the top of my head but no doubt someone will post a link for up to date regs. I have put those links below, and an explanation.... road bridges have there height marked if they are under 16 ft so if not marked they must be 16ft or over so 16ft must be the standard height for major road bridges , Max height is governered by motorway bridges as they are 16', .... Dougy The Standard height for an unmarked bridge in the United Kingdom is not 16' 0" rather it is 16' 6" . (5.03m) It should be possible to run under any unmarked bridge, or overhead cables provided your height does not exceed 16' 6". Although most HGV websites advise, just to be on the safe side to allow for measuring inaccuracies, a maximum height of 16' 3" in the case of a decked trailer carrying an irregular shaped load, (16' 6" is normal recommended max height for a box bodied vehicle where the height can be more accurately determined). http://www.direct.gov.uk/prod_consum_dg/groups/dg_digitalassets/@dg/@en/@motor/documents/digitalasset/dg_191921.pdf H.S.E. documentation states that standard height of Motorway bridges is 5.1m (which I calculate translates to 16' 8 3/4") http://www.hse.gov.uk/workplacetransport/vehicles.htm http://www.transportscotland.gov.uk/road/bridges-and-structures/high-loads All unmarked structures in Scotland have 16' 6" or greater clearance http://www.transportscotland.gov.uk/files/prevention_of_bridge_strikes.pdf This Same Height applies to whole of UK. Bridges (according to Department of Transport recommendations, Chapter 4 of the Traffic Signs Manual (TSM) 2, section 7.) SHOULD be signed with a safety margin of 3" or 0.1m, so a bridge marked at 16' 0" will safely pass a 16' 0" vehicle. the actual clearance under a bridge signed at 16' 0" SHOULD be 16' 3". A Bridge that is physically 16' 6" would therefore be signed at 16' 3", and this explains why Motorway bridges according to HSE are built to 16' 8 3/4" This being a guaranteed safe height of 16' 6" plus this 0.1m extra margin of safety, and why it is safe to run a 16' 6" box bodied vehicle under an unsigned bridge.

(Reg 7 Construction and use regulations 1986.) and see http://www.transportsfriend.org/road/dims.html Thanks. Just learnt something new. Normally only get involved with semi-trailers for distribution centre and warehouse yard design. Not many lowloaders there. Mike Quote Link to comment Share on other sites More sharing options...
0 N.O.S. Posted February 20, 2011 Share Posted February 20, 2011 And an interesting exclusion of 'step frame' low loaders from the 'low loader' 18m category - with the vast plethora of specialist trailer designs around these days it would be interesting to know at what point a trailer ceases to be a 'step frame' and becomes instead a 'low loader' :cool2: Quote Link to comment Share on other sites More sharing options...
0 R Cubed Posted February 20, 2011 Author Share Posted February 20, 2011 oh whats the difference between a low loader and a step frame :undecided: thought they were the same thing. Quote Link to comment Share on other sites More sharing options...
