Securing a rock drill

We like seeing iron in action. Getting down and dirty gettin' the job done, heck yeah.

 

If it were me, I would change a couple things, but I'm old and fussy.
In the first pic you ran the chain over that square tube part of the frame at the rear.
I would put a choke on that tube, which is simply passing the chain over the tube, then under and around the chain once or twice on the other side and back to its pocket for tie down.
This way, if the machine moves, the chain will choke the tube and keep it from sliding to the side, forward or back.
There's also holes in the frame at the back for securement or lifting that you could have used instead.
Get the pliers out, pull the cotter pins out of the hooks and pass the chains through the holes, 30 seconds per side, stow the hooks until you're done with the load.
Second pic looks like you passed one chain over a bunch of hoses or electrical cables, that's a no no.
I would have used a couple chokers around that heavy piece near the pivot.

 

Or carry a selection of shackles, just make sure they are stamped with the WLL. Also know how the WLL is affected by loading.

 

Here's a couple of different drill pics. Took me awhile to find them lol.
