1.Selection of power unit
Power unit and rock splitter are connected with a pair of high and low pressure hydraulic hoses. Flow distribution bars are available which permit the use of up to four splitters from one large power unit. Note that they can only operate simultaneously, not intermittently or individually.
Hydraulic pressure applied (Maximum 7100 PS) is used by all size splitters enabling the same hydraulic pump to be used for all models.
Power units are available in three types- air, Gas and electric to suit all job conditions. When selecting a power unit, the following point should be considered:
1)Air- Since most of the time air power is used to drill, power unit with air motor will always be useful. No exhaust gases, not affected by water.
2)Gas- When all available air must be used for drilling, or whne compressor is removed prior to splitting, or where power unit must be moved around frequently, a gas power unit is advantageous.
3)Electric- It is quiet, no exhaust gases, useful inside building, crusher installations. Less maintenance required.
All models can be converted from one power unit to another. Gas to air, electric to gas, air to electric.
2.drilling holes before using Piston rock splitter
Hole drilling is usually done with a conventional rock drill. to prevent dust, either a vacuum attachment or water flushing can be used. On work where all noise and dirt must be prevented such as in hospitals, computer centers, or control twoers, a diamond core drill is usually used to pre-drill the holes required for splitter.
It is very important that the holes should be of exact diameter, length and straight. Integral drill steel is readily available which combines accurate diameter with short effective length to permit comfortable drilling. Notice the importance of having a close-hole diameter.
if for some reason the drilled holes are short, it is possible to hold the toll out of the hole the same distance as the difference between the actual hole and 26"
Drill operator should keep drill steel firmly positioned in center of hole from beginning to end; otherwise,a crooked hole will result deformation will lead to fatigue and breakage of the entire plug and feather assembly or part thereof . if deeper holes are drilled using two lengths of drill steel, make sure the lower part of the hole has almost the same diameter as on top. A step in the hole could cause "hang up" and possible breakage of wedge. Drill steel is available which is just long enough to permit drilling entire hole in one operation.
If many holes are drilled by different operators,the hydraulic splitter operator should check each hole with a ruler or broomstick to make sure that hole is deep enough and free from hard obstructions. The plug will break if it is forced against solid rock.
