Attaching the Beams
Potential Hazards:
Injury from movements and
posture, hand injury from pinch points, strain to wrists
from tightening bolts and excessive noise from use of
impact driver.
Recommended Control Measures:
Observe correct
techniques when lifting rails (bend at the knees), wear
gloves, use a pinch bar to align holes, use an impact
wrench to tighten bolts and wear appropriate hearing
protection.
Position the
RiderPro
beams below and parallel to the
thrie
beam guardrail. Attach them to the mounting
brackets with two M16 x 35 mm guardrail bolt (Ref.
in Figure 4) using standard nuts and round washers,
but do not fully tighten them yet.
The beams must be overlapped with the flow of
traffic so that the leading edge of the splice is
shielded from the nearside approaching traffic.
Splice beams together using four M16 x 35 mm 8.8
guardrail bolts (Ref.
in Figure 4), standard nuts and
round washers.
It could be helpful to use a pinch bar to align the
holes at the splice, to make bolt installation easier.
Any elongation of the splice holes is strictly
FORBIDDEN.
Tighten the four bolts of the splice to snug fit (no
specific torque is required), avoiding for now to
tighten the two bolts that connect the beams to the
mounting brackets (see § 9.7).
