I am sure Charlie would agree that moving heavy things takes a lot of  
forethought and a finely tuned attention to safety. I would prefer to crib the  
load up, as Charlie has previously described, with plenty of margin for 
safety  all around so that the load cannot slide to one side or fall more than 
an inch  or two at the very most. Perhaps a professional rigger might be 
worth the  expense, if only for advise? 
 
It's that inclined ramp, it's ability to support the load =as it moves=  
(meaning a dynamic load) -  and the load's =tendency= to move on such a  ramp 
that would cause me concern. I helped my father move a Chandler and Price  
printing press down a hill one time...long story that almost ended in  
disaster...almost, but not quite. 
 
My two cents and worth what you paid for it! 
 
Might we ask what the "heavy object" might be...a printing press, perhaps?
