Any suggestions on hammerin concrete floors, foundations, support colums, train tracks in cement, any other structures in old steel mill? Thanks Bob aka ZZ
1. the bigger the better. 2. don't forget ear plugs
Set up some shielding on the machine to protect the cylinders from flying chips.
Let the hammer do the breaking,avoid dry firing, and NO PRYING!
Start at the edges of hte floors, and tops of the pillars. Break into sizes you can handle with your removing machine(skid loader, loader, etc) Grease that hammer often. Try to keep the hammer perpendicular to what you are hammering on. Don't hammer non stop for long periods. One other thing i learned when i first ran a hammer(the hard way i might add). Was try to keep it so your stick cylinder(the one mounted on the top of the boom) is extended the least amount to avoid bounce on that cylinder. Took the seals out of the end of the cylinder and was leaking like crazy. Trbo
Don't hammer with any of the cylinders extended or retracted the whole way. It will beat the piston against the barrel.
Depends on equipment and what your doing with the concrete. We don't hammer anything unless its so thick we can't break it out with a bit of effort. Push over the columns. Pull up the floor you may have to hammer where the foundation is underneath. Dig around the foundation and pull it out. You don't want to pulverize everything while its on or in the ground or its going to make a mess to clean up. You don't need to apply much if any down pressure to the hammer and you don't nee yo punch a hole clear through the floor normally 2-4 hits of the hammer is enough.
allways hammer perpendicular to the floor or the chissel tipped slightly away. The chips that come off the first couple of hits will hurt if you get hit. Allmost lost a tooth once.
You are going to find as much or more rebar as concrete. That will be the nightmare to deal with.
