Poweramp RAIL RAMP SPECIALTY 1.1995 - Manual (Page 8)

Installation Railramp Track
Flush to outside building wall and plumb.
You have determined that your installation has existing curb steel. Prior to installing the
railramp, the railramp track must be installed. The following steps will explain this procedure.
1. Check transition plate and railramp track for damage (See Fig. 4) that may have
occurred during shipment. All dimensions should be checked against a certified
installation drawing. It is the contractor’s responsibility to properly install the transition
plate and railramp track.
2. Verify that existing imbeds have sufficient anchoring. Minimum 6" long anchors on 12"
centers are recommended. Remember the railramp operation is relying on sturdy
anchoring. If anchoring of existing imbeds falls short of recommendations, do not plug
weld railramp channel to imbedded steel. Instead, drill through imbeds and utilize all
the anchor holes.
3. Clean and remove all existing protrusions from the dock face. Railramp track must fit
flush with the outside building wall.
4. Center rail in doorway, mark end points allowing an additional 1/2" on each end.
5. Measure down on face of dock from edge of dock 10-3/4". Draw or snap a line parallel
to dock floor the length of the railramp track (See Fig. 5).
6. Measure in 3-1/2" from end chalk marks and down 9-1/2" from dock floor. This will
locate the extreme lower end anchor points.
7. Drill ten holes, per 10' section, for 5/8" x 6" anchors.
NOTE: If existing curb steel has a vertical face of 10" or greater and is securely anchored,
railramp track can be plug welded to curb steel through ten holes provided; thus eliminating
step 5 and anchors required.
8. Measure back 12" from the dock edge and chalk a line along the dock floor parallel to
the edge of dock the length of the rail (See Fig. 6).
9. Cut a groove 2" wide by 3/8" deep the length of the chalk line. The outside edge of the
groove should be on the chalk line with the groove opening towards the edge of the dock
(See Fig 6).
10. Position the railramp track on the dock face. The top edge of the railramp track should
extend above the dock floor by 1/4".
11. Position the transition plate in place and using it as a template, drill anchor holes.
12. Secure transition plate with 5/8" x 5" anchors.
13. Weld and/or burn off anchor heads. This procedure should be done one anchor at a
time to assure a secure mounting. Remove head, weld stud to plate, grind weld flat to
assure smooth surface (See Fig. 6).
14. Proceed with railramp installation page 10.
