The concrete properties must be, at minimum
3000psi. A smooth finish is required so the
Pivot & Catch posts sit flat, level, & plumb.
M30 INSTALL FOUNDATION
To make sure the stability of the StrongArm M30™ Crash Rated Fortified Barrier Arm,
the foundation must be constructed in accordance with the following guidelines:
• Excavate a hole for the foundation to house the rebar mats and anchor bolt assemblies.
Soil compression under and around the foundation shall be compacted to
a soil density of 95% of standard proctor (ASTM-698).
• Add gravel where necessary to ensure a solid soil base. Soil must be stable and
adequate to support the weight of the foundation.
IMPORTANT:
Softer soils require a larger footing. Employ the services of a structural or
civil engineer for site specific considerations. In Northern latitudes, consider the frost line.
Re-measure and adjust to
correct mis-alignment issues.
Ensure anchor cage location
is maintained while
pouring the concrete. See Tip.

Tip:
Tack weld base of anchor
cage to lower rebar (4x). Keeps the base of cage from floating when pouring the concrete.
Measure and lay conduit:
• Two separate 1-inch diameter conduits for the high voltage power and low voltage power controls.
• Conduit for vehicle loop wires. One separate conduit for each vehicle loop installed.
• Separate conduit for Earth ground.
• Appropriately-sized conduit between the operator Pivot Post and Catch Post for optional items such as:
thru beam photo eye, traffic light, Mag Lock, or heater.
Lay rebar mat pattern 7 by 7 at 10-inch on center (OC).
Use #5 (⅝ inch) rebar: 10 lengths of 20 ft. (6m)
Cut 28 pieces of rebar 5½ ft long (168cm).
For the vertical pieces, cut 8 pieces of rebar 19 inches long (48cm).
Install the anchor bolt assemblies as shown.
