Hmmmm yes the rams are extremely light, which leaves me to wonder what they are made from... The big rams have a stroke of 140mm, was planning to use these on a 3:1 lever ratio to help with grabbing speeds.
Will look into sourcing a single, fat ram. 32mm would be ideal. I'll see if anything crops up on ebay that will fit the bill.

Is there a standard in how to prevent the pump from overworking when the ram is at its full extent? The rams i'm using at the moment are sensored, but I can't imagine many second hand rams on Ebay having such features.

EDIT:
Something like this seems to fit the bill.
