There is also the consideration of what is being cut growing away from the machine - the weight itself might be ok but that weight might actually have a centre of gravity at a greater radius than the cut point. Depending on the head it may not fall to vertical, but instead massively increase leverage (and subsequent tippy-over-forces)…

I’m also surprised that we haven’t seen a big hiab grapplesaw through a house roof yet - once these units get old and second hand and more affordable I foresee carnage! 

Exactly that. The reason I bought the GMT was that I would have the ability to pick stuff apart and not swamp the guys on the ground. There's nothing worse IMO when massive bits (particularly when doing crane work) land on the ground and it takes ages to get them cleared. I'm all for slow and steady. 

 

I avoided the westtech because I believed that with the reduced manipulation at some point you'd be forced to take a larger section.....and then the inevitable happens

 

also why I generally avoid working for other contractors as they might have underpriced or not really understood the process so get urged to hurry up etc
