RAM INSTALLATION – APE AND DRAPE
1. Do not lift the ram assembly by the plunger. A sling should be secured under the
ram flange. The shipping wire on the end of the ram that was installed at the factory
should be kept intact until it is time to operate the ram. This will prevent the plunger
from turning and falling inside the casing.
NOTE: The ram plunger surface must not be scratched during installation!
2. If the footing is not pre-set, suspend the ram in the hole at the proper height and
block it into a plumb position. For single ram installation, be careful to properly
orient the non-rotator pipe, when used. For dual ram installation, use the spreader
channels to properly position the rams for cable equalization, when used.
3. Plumb in all planes by using a spirit level horizontally across the top edge of the
plunger. Re-check with a level at right angles across the plunger.
4. Connect the elbow and riser pipes to the ram. For dual ram installation, connect the
piping between the rams. Temporarily cap the top end. Use suitable pipe joint
compound on all male threads. Make sure the riser comes to at least 12” above the
finished elevation of the pit floor.
5. When the ram is reasonably level and centered, pour sufficient concrete to make the
footing come up several inches above the bottom of the cylinder. Do not encase
the entire cylinder length in concrete, or the ram casing removal will be
impossible. Allow the concrete to set for 24 hours.
6. Begin backfilling with clean sand. Do not use cinders or other corrosive backfill
anywhere near the cylinder or the piping. Fill the hollow ram-plunger with clean
sand. This ballast is absolutely necessary for the rams to come down unloaded for
proper lift performance and service convenience. Do not put any foreign material
into air-over-hydraulic plungers; this will ruin the ram.
NOTE: Prevent sand or dirt from getting around the seal-ring recess.
7. Tamp the backfill well and continue to recheck for proper centering, non-rotator
position, and always recheck that the cylinder is plumb. Off-center positioning of
1/8” is acceptable, but 1/16” off level across the 10 _” diameter plunger will indicate
that the cylinder is more than _” off plumb in its 90-inch length (for 60” travel).
