Although, writing that I've just thought that as the hydraulics would be under load from tbe box, you might not get the connectors apart. You can get some couplers that are designed to be connected under pressure - e.g. a Bobcat I hired with a sweeper collector had some "quick couplers" - they had a very slight thread on them which only needed to be done up hand tight but they had a double stage inside the couplers to relieve pressure. Weren't cheap though because I broke two , one was £60ish and the other was £30ish. Quote Link to comment Share on other sites More sharing options...

L19MUD Posted December 21, 2020 Author Share Posted December 21, 2020 No fancy couplings here! Legs all now made and the front ones test fitted. I couldn't get the box section sizes i needed so i welded some angle to the inner section to get a nice telescoping fit. Obligatory picture of a decent weld included (wish all my welds looked like that!) Quote Link to comment Share on other sites More sharing options...
L19MUD Posted December 25, 2020 Author Share Posted December 25, 2020 Well the legs are finished and that part works well. Just got to make the pegs to locate it on the trailer. Only just fits in the shed! 1 Quote Link to comment Share on other sites More sharing options...
landroversforever Posted December 25, 2020 Share Posted December 25, 2020 Nice one! What are you doing for mounting to the trailer? Quote Link to comment Share on other sites More sharing options...
Arjan Posted December 25, 2020 Share Posted December 25, 2020 Mini twist locks ? or just a box section through the floor and a locking pin ? Quote Link to comment Share on other sites More sharing options...

The holes where the posts go for the sides accept 50x30mm box section. I designed the leg sockets to go above those holes so i can weld some box underneath to drop in. I think i need to shape the box section into a point at the end to aide fitting. I will then have nuts welded into the box to bolt into 1 Quote Link to comment Share on other sites More sharing options...
L19MUD Posted December 31, 2020 Author Share Posted December 31, 2020 This shows my plan but i am worried that unless i get it perfectly right it will be a nightmare to get it located each time. The body is a little far forward and not quite centered in this picture as that box section socket should come to the edge of the trailer. Suggestions welcome Quote Link to comment Share on other sites More sharing options...
steve b Posted December 31, 2020 Share Posted December 31, 2020 stick a plate on the top of each peg that is just big enough to get a weld from above , drop all four in place position the box in the right place and weld . Remove box and complete the welds on the under side Steve Quote Link to comment Share on other sites More sharing options...
landroversforever Posted December 31, 2020 Share Posted December 31, 2020 Guessing you’re worried about lining it up each time? Could you have some kind of adjustable sliding/bolted joint? or some kind of turn buckle arrangement? Quote Link to comment Share on other sites More sharing options...

My first thoughts were making the box section slightly pointed in both directions to aide location. Have thought of both of the above but not sure how to do it!

Retroanaconda Posted December 31, 2020 Share Posted December 31, 2020 What about something similar to the pins that attach shipping containers to lorry trailers and rail cars? Though on a smaller scale obviously. I think they are a slightly tapered pin that turns to lock. Quote Link to comment Share on other sites More sharing options...
steve b Posted December 31, 2020 Share Posted December 31, 2020 This is what I had in mind , the pyramid would be easiest to fab. from flat plate . Securing it down to the bed can be ratchet strap/ turnbuckle/ steel strips that align with existing holes in the bed or even short chains attached to box and bolted to trailer As to lining it up I reckon with the trailer roughly in place unhitch it and just shimmy it in place as you go . Marks or blocks to run the wheels up to would also help. Steve 1 Quote Link to comment Share on other sites More sharing options...
elbekko Posted December 31, 2020 Share Posted December 31, 2020 Could slit the 4 corners of square tube and make a pyramid shape like that? Quote Link to comment Share on other sites More sharing options...

Would end up bigger than 10mm on the side though Quote Link to comment Share on other sites More sharing options...

steve b Posted December 31, 2020 Share Posted December 31, 2020 I wondered about a nut welded in to bolt it down with . My dimensions are just an indication - keep roughly that angle and make it shorter until you can get a nut in . As elbekko says slit the box will work just as well , just me accidentally dropping into quantity production mode 1 Quote Link to comment Share on other sites More sharing options...
L19MUD Posted December 31, 2020 Author Share Posted December 31, 2020 Sounds like I have a plan then! Do we think 4 m12 bolts is enough to hold it down?! Could add a couple of ratchet straps Quote Link to comment Share on other sites More sharing options...
steve b Posted December 31, 2020 Share Posted December 31, 2020 Strength wise , yes , my only concern is keeping them tight . Trailers do vibrate/bounce about somewhat so maybe some sort of cotter pin/R clip arrangement to stop them moving once tight would be the belt and braces solution ? 1 Quote Link to comment Share on other sites More sharing options...

Could add a couple of ratchet straps With how it's built it's probably overkill except maybe in a rollover. Just add a nyloc nut at the back, should fix the vibration issue.

JohnnoK Posted January 1, 2021 Share Posted January 1, 2021 What about fabbing up something similar to a Stacking Cone to loacte the body in a suitable hole in the trailer bed and then using Twist Locks to secure it? Both are on this page... https://speedspares.co.za/component-catalogue/other/ Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted January 1, 2021 Share Posted January 1, 2021 Depending on if you can access the outside of the square tube on the trailer, you could drill a hole though the tube and the square tube of the container body location peg and put a pin through the whole lot, like a lynch pin or something?
