G,day Lowboy. I'm not nit picking cause I think you did a good job....but how do you think that arrangement would go if someone was to calculate the required fore and aft restraint on your rules. It looks like you got lateral well covered.
No nit picking detected here, Squizz. If you analyze the photos closely, you'll see there are a set of 1/2" chains diagonally across front and rear of tracks to a D-ring. In addition, there are ALSO a set of 3/8" chains in the same configuration. I added THREE 3/8" chains to secure the cutting head and stick, which would
exceed the chain rating maximum requirement of 30,000 lbs. for the 3 chains being used.
Fore & aft movement is virtually eliminated by the degree of angle in which the chains are pulling away in both directions from the trackframe and/or pads themselves.Thus, shooting holes in the fore & aft movement issue.
Where we have to be careful here in the states, is in WHERE we secure the end of the chain or binder, meaning the hook, to. I've been informed that by going from the beam of the trailer with a hook, whether it's a chain or binder, will reduce the working load capacity by 50%...Poppycock in my opinion, but my opinion carries NO weight (no pun intended,) with the authorities I have found in the past.
That big 'ol gal had four 1/2" mankiller chains diagonally binding it down, plus four 3/8" chains diagonally binding it down, PLUS three 3/8" chains holding the stick and cutting head. If it were to want to come off that float mate, believe me when I tell you, it was taking me with 'er...:drinkup
