7.0 Barrier arm support
Barrier arm length exceeding 14ft require a support of the boom arm in the lower end
position to cushion the arm when it travels in the down position. Magnetic Automation
Corp. offers two options of barrier arm supports:
7.1 Pendulum support
The pendulum support (Part# 1043.0138) is mounted to the barrier arm via two Allen
head bolts (see drawing below).
Note:
Depending on roadway conditions, the pendulum might have to be lengthened
or shortened. To change the length of the support loosen the three set screws
located on the center ring of the rod and turn the bottom cylinder clockwise to
lengthen or counter clockwise to shorten the support. When the gate arm is in
the down position, the distance between the rubber stop and the beginning of
the tube should be at about 14”. This results in a good damping effect and
prevents the rubber from freezing to the tube in cold climate. After the proper
length has been adjusted, tighten the three set screws again.
7.2 Support Post
The support post (Part# MAP5N-110) is mounted to the ground on the end of the gate
arm. The arm drops into the cradle when the barrier is in the down position (see
drawing)
