Look at
www.bearcatmfg.com and
www.crafco.com Both of them make their own version of a crack seal machine. They both suck for service and they are both here local and it is like pulling teeth to get service even on new units, imagine trying to get parts where you are.
Bearct has a better heat system as opposed to Crafco, but they both use the same material pump that just so happens to be made by one of the sons of the founder of Bearcat. They aren`t bad pumps, but they lack the ability to heat the rear pump section unless you get the latest and greatest pump they make.We made our own heat set up and increased life about 6 or 8 month over the orignal set up.
Then there are routers, Crafco has one and there is
www.cimline.com Here again, they both suck. They cost about $10,000 each and we had Crafco`s blow up engine and cutter drums in a month. Guess what warranty was ? Nothing. Crafco blames everybody but their own design. Along with the routers you need the cutter bit. From Crafco they are about $300.00 EACH. You need 6 per machine plus pins.
Almost forgot about the crack seal hoses. Anyone not paying attention can plug up a hose in a matter of minutes at between $150.00 buying them by the 6 pack all the way up to $600.00 per hose for the best ones.
I guess there is $$$ to be made doing it, but you really ned to keep a tight reign on what goes on or the money will dissapear real fast. Good luck. PM me if you want any other info. I don`t have even half the answers, just what I had to contend with for 3 years keeping a half dozen of them running.
The cutter head won`t work for crackseal as that is what the router is for, you only want to widen the crack at the top to give the material a sudface to bond to, not remove the pavement surface.
