Let me have a go at this…
…working with a 40’ trailer, or any length of loaded trailer that’s equipped with conventional rope hooks whether it be a double decked load, or single decked, ,… once the back and front sheets are in place and secured, take three long ropes, it doesn’t matter how long they are as the length of the rope is irrelevant. But first off, rope across the headboard, then the back end , in order to secure the sheets.
My next step would be to throw a loop over the In the middle, where the sheets meet, to prevent them from sliding. Then, after making a cross, front and back, it’s just a simple matter of throwing rope loops over and working inwards towards the middle from both ends simultaneously.
It isn’t quantum physics, and there isn’t a great deal of walking to be done actually, you just do three or four hitches on one side, then three or four on the other, with possibly an Aberdeen spider on the back end to use up the last bit of rope ( or show off a bit ) and you’re good to go.
The only time I’ve worked with cut ropes was on the Chep pallet job, when we cut the ropes into 40’ lengths in order to secure the 20 high stacks of pallets. ( A nylon strap was used front and back incidentally).
I’m not attempting to to teach my grandmother to ■■■■ eggs here by the way , it’s just that there may be the odd transient visitor looking in that may find my methods illuminating.
Moving on to the problem of roping to a horizontal bar. I only ever encountered this situation when reloading Lancashire flats for Irish Sea Ferries to go back to Garston dock.
The condition of these Paddy flats could probably best be described as being, well, careworn at best, but more frequently, abysmal…On the odd occasion, I’ve even been refused a backload, due to the fact that a fair percentage of the floor timbers on the abortions were either broken, or missing,…or both.
But getting back to these horizontal bars…Throw your loop over the load…pass the loop under the bar…bring the loop back up as far as you can reach, then place the loop over the vertical section of the rope…grab the vertical rope that is now lying under the aforementioned loop and pull it through.
Pull about a yard of rope through, then proceed to form a conventional hitch using the rope that you now hold in your right hand, ( I’m assuming that you’re right handed of course ).
You’ll then tension the rope with the loose end that’s already passing under the bar.
It all sounds complicated but it’s a piece of ■■■■ really when you’ve done it a couple of times, but I’ll have to leave it there, as there’s smoke coming under the door and a smell of burning pizza coming from the next room.
