How is this done ? Where do you block the machine up ? How wide is the trailer deck ? Is the machine blocked and then lifted with the trailer or is the machine lifted with it's boom and then blocked ?
I cant answer all the questions but hope this will help
We call it belly loading and is usual for over height and / or heavy wide loads that will do more harm than good to the outriggers.
That trailer is almost certainly on air which makes it very easy.
Drop the air out of the suspension, split the neck and pull clear.
Track / drive the load so it straddles the bed but is still on the ground.
Block the machine between the trailer deck and the underside of the machine. Positioning of the timber blocks will be governed by the load bearing members of the trailer and where you can block the machine.
Chain the machine securely.
Hook the neck back on and inflate the air. The load will lift off the ground.
Additional clearance of the tracks can be gained if it is parked on timbers before blocking the load. When lifted it will be belly loaded but higher by the height of the blocks you parked the machine on.
Once off the ground,
If the machine has worn/loose tracks the slack can be taken up by placing a steel pin ( or similar) in the top of the drive sprocket and reversing the track ever so gently, this pulls the the slack from the bottom. ( I spotted that on a pic posted a while ago
)
The other option is a beam trailer. The loading is basically the same but the deck is only a centre beam, much narrower than a standard trailer so heavy loads that do not have 9' clearance between the tracks can still be carried low. :drinkup
I cant guarantee it, but I suspect these are beam not a full width deck.
