Try a company called Simark in Rowley Regis, they do a lot of load restraint systems or may know of somone who has something more to your requirements. They do a lot of equipment for hauliers and the online supermarkets, hopefully they have a solution. https://www.simarkengineering.co.uk/ Or maybe @Robert Colliver knows of such a company?
I don’t think that’s it. That tube on the top of the jack slides over a bar which protrudes from the suspension assembly so that you can raise it. As far as I can tell, the jack doesn’t remain attached to the trailer but is removed and stored separately after it has done its job. Perhaps it’s equivalent to a “hedge bolt”?
I reckon it does fit where you have highlighted and perhaps keeps the trailer level when jacking it up e.g. if a bike is particularly rear end heavy is it possible for the ramp to dangerously tilt transversely wrt to the van? And as such it is an important part of the jack so what better than to chain them together.
I'll have a wander over to whether I've parked it but I don't think that will be what it is for as I don't think the chain is long enough and those two square sleeves cannot move independently of each other anyway as the chequer plate channel is fixed to the structures to which they are welded.
Z You've got me intrigued by these trailers, so I looked at the video linked by ymfb - http://www.easylifter.co.uk/hydra-trail.htm At 1.07 the guy putting it together reaches down, picks up something off the floor attached to the jack by a chain and fits it. Trouble is you can't see what it is or exactly where he puts it, but it gives you the right area. The image in post #39 in this thread also shows the chain going to where you suggested in #119
Yeah, same here ... it's a substantial piece of square bar so you'd think it must be load bearing rather than just for locking purposes. Perhaps it distributes the lifting force across a couple of points on the chequer plate rather than just one.
I reckon it's a different, previous or later generation, method of what this guy fits at 3.28 here: Yours doesn't have the fitting his does, but his doesn't have the two bits of box that yours does. To stop the trailer pivoting whilst you jack it up.
Yeah. I watched that video yesterday and noticed the same thing. He also refers to “retaining bolts” which he tightens up but mine doesn’t have those either. There are a few other differences - for example my wheels are in a different place and their retaining pins are on the side rather than the top
Good spot. You can also see him pull it out at round about the 3 minute mark. The only place it can go is through those two square bits of 1” box section.
I reckon yours is a later version as the manufacturing cost of your method to stop it tilting would be cheaper.
I think its function is to brace the chequer plate platform and stop it sagging while the bike is being raised, but once the wheels are on, there’s no need to brace it anymore.
Sort of. We may be saying the same thing, but without that brace in place, and no wheels to support it, when you jack the platform up the heavy end will stay down.
It’s incredible that they don’t supply instructions and so you just have to try and work it out using the video. They could find themselves dangling on a very large legal hook if someone was injured as a result of omitting that step and let’s face it, there’s a lot of scope for injury (or worse) when you’ve got hundreds of kilos of motorbike and metalwork waving around in mid air right next to your head.
Yep... we're defo all sortov saying the same thing. From the second photo Z posted it looks like the chequer plate is made up of two pieces with only the one on the rhs of the photo sitting on top of the bar that the jack actually lifts.
I remember once hiring out a rotavator and after excited assembly there was a T bar left over... hey ho must have being mistakenly added. So I fired him up and found it took immense strength to actually use as I couldn't stop it from just ploughing on through the fence and into next door... fuggin hell I've watched old boys of 70 use these & here I am getting dragged behind it like a wet towel.... So after much thought I realised the T bar fitted under the handles so when you press down the bar acts as a brake allowing the blades to dig in and when lifted up it allows forward motion... it was now so easy even a 5 year old could have done it... ho hum.
Managed to get two in today. Now looking for a solution for two more in the rear section. Movable front wheel chocking seems to be the challenge. Unless any of you know better
I use these in my van https://www.amazon.co.uk/Youyijia-Motorcycle-Motorbike-Adjustable-Transporting/dp/B0933DK6CD
