The Upswung MB832 manual barrier gate arms range from 8 to 32 ft long, constructed in heavy extruded aluminum tube. This aluminum tube specification allow arm lengths up to 32 feet and the ability to withstand high wind loads in shorter lengths as detailed in the Engineered Wind Load Graphs link on this page.
The round profile of the MB832 arm boom eliminates flagging of the arm in high winds reducing possible aluminum metal fatigue. The MB832 base is constructed in thick wall structural steel tube welded to a heavy 4- bolt steel base. The swing arm pivot assembly uses composite bushings with a through bolt pivot assembly that requires no lubrication. The swing arm is constructed in structural steel with a strong clamping system to control long aluminum barrier gate arms. Stainless steel allen-socket bolts secure the barrier arm to the steel swing arm. The counter balance weights are adjustable for fine tuning the balance of the arm. Adjusting position of the counter balance weights control the speed and direction (up or down) of the barrier boom
