4. HANDRAILS
4.1. FRAMES
4.1.1. Two-line rails, picketed guards, and handrails are specific to the ramp length and
provided in pairs when ordered with the ramp. The procedure for frame attachment is
the same for the two-line rails and picketed guards. The procedure for installing handrails
is explained in a later step.
Two-line rails can also be field-converted to picketed guards if needed.
4.1.2. One frame is required on each ramp side (frames are interchangeable side-to-side).
4.1.3. In a multiple ramp run configuration, handrail connectors (included in the TRRC –
CONNECTOR RAMP TO RAMP) are used to join both frame top rails and handrails
together. Refer to FIGs. 4.1 and 4.2 for the following steps:
4.1.3.1. The vertical posts of the frames each have two holes which correspond with
the studs on the end of center saddle brackets (installed in previous steps).
4.1.3.2. Attach frame to these studs using two each 5/16″ flat washers and two each
5/16″-18 nuts per frame post. Tighten 5/16″ nuts just enough to hold the
frames in place.
If the studs do not align with the posts the frame, the end saddle
bracket is most likely installed into the wrong threaded insert in the
ramp side rail (see FIG. 3.2 for proper installation location).
4.1.3.3. Slide handrail connector into one end of the frame’s 1-1/2” diameter top rail.
If handrail connector does not fit in tube, use pliers to lightly compress
the handrail connector while sliding into the 1-1/2” diameter top rail.
4.1.3.4. Slide the next frame section over the handrail connector, ensuring the top
rails are pushed firmly towards each other. Compress the handrail connector
and/or use a rubber mallet as needed.
4.1.3.5. Rotate frame until the holes in frame post align with studs in saddle brackets.
4.1.3.5.1. Attach with 5/16″-18 nuts and 5/16″ flat washers, tightening
just enough to hold the handrail in place.
4.1.3.6. Repeat for the remaining frames in the run, then tighten all the fasteners
securely.
