Trailer Build

[Zebbedee]

Its nowt to do with a lack of grasping the design and in not saying he's wrong and that there will be anything lacking in the finished trailer. But a trailer for the back of a tractor and for the back of an articulated truck are two very different types of trailer and subject to very different point loadings so to assume because beams are used in truck trailers that most be the only way to make a trailer isn't true.

I get what your meaning as my thoughts on it are hgv trailers are designed to flex and need to be light whereas Ag trailers don’t want to flex and farmers seem to think the heavier the trailer is then the better it is !!!! Not much design needed on an Ag trailer just add more steel it seems to be and box section chassis are easy to fabricate and look the part too hence why lots of Ag trailers are box section

made the box for the spring drawbar pivot and fitted it this morning , completely welded together as no chance of distortion , will have 2 grease nipple in the back of drawbar , 50 mm Pin will be captive

Very nice work. Fortunate to have the space to do something like that look forward to seeing it to completion

Is this the trailer you were asking about a load sensing valve? How about on the sprung draw bar?

I would say to much movement on drawbar , i think i’m putting it between back and middle axle

I cant see the harm in a small bit of flexing. Only thing I have against RSJ in an ag environment is all the crap it can hold leading to corrosion. Looks very well designed so far.

Fifth-wheel support is very different from the single point loading of a pick-up hitch..

looking good … but the only thing I want to ask about is..
Will the axles,suspension cope ok with the severe scrubbing action of fully loaded trailer turning short on hard surface
30 or so years ago I used to work at small rural garage, twice in a couple of weeks a local contractor brought in his double axle silage trailer with broken stub axle to fix

Super clean steel. Lovely looking job, can't see this turning out anything but a first class trailer.

full commercial axles same as a lorry trailer rated at 11.5 ton each and i will observe the welding zone for hangers in the manufacture instructions

 

[Nearly]

instructions?

 

[Forever Fendt]

instructions?

there is only permitted zones on the axle where you should weld and how much weld do not to cause problems with axle tube

@Forever Fendt looking good and looking forward to seeing the completed trailer. What grade pin did you go for on the drawbar pivot and if not too nosey, how did you arrive at the diameter to use?

50 mm EN16 pin

Trailer build thread ? On TFF ? Page 2 ? And no one's turned up to waffle on about getting it plated ?

that’s so very last year

How/where do you get steel that clean?!

it’s had a flash blast , quick run through the blaster before it’s cut , will then get a light manual blast before painting as it will get a bit if atmospheric rust , would be better in summer really dry atmosphere

I notice you have a lifting beam down the centre of the roof. What sort of weight can you lift from that?
