I've been looking at replacing my 2001 cat 302.5 with someone stronger and with a cab. I want something that can handle a decent hammer in case I run into some rock...which we have a ton of here in bend.
I've tested an HR16 by Terex, seemed like a nice machine.
It's a 7700lb machine with a bucket force of 8000lbs and a stick force of 3600lbs. One thing I noticed is that the cylinder for the main stick is on top instead of below. The sales person that it's to prevent damage.
I'm also interested in 2005 model or older Cat 304cr. From what I've heard they are nice machines. ~9500 lbs versus the new ones at about 10,500.
As far as a hammer goes, the local Terex dealer is putting a atlas copco PB 310 on their HR16. They say that the PB 310 is rated for a 11k to 19k machine, but th HR16 handles it just fine.
Cat says that they will only rent you a 500 ft lb breaker for the 304 or 305. It seems like if the HR16 can handle a PB 310 which is a 750 ft lb breaker, the 304 or 305 should be able to handle a PB 420 (1000 ft lb). The older 304s have about 19 gpm on the aux. and the PB 420 need 16-24. I'm guessing cat doesn't want the liability of letting you rent a hammer that's rated for a bigger machine.
Does anyone have any experience sizing a hammer to their mini?
Thanks,
Daniel
