Frequently Asked Questions
What safety features are included with your drop arm barriers?
Our barriers typically include safety features such as obstruction sensors, emergency stop buttons, warning lights, audible alarms, and optional integration with crash detection or access control systems.
Can drop arm barriers be used in high-cycle environments?
Yes, certain models are specifically engineered for high-cycle use, making them ideal for locations like ports, military bases, and transportation hubs that require frequent raising and lowering throughout the day.
What are the power requirements for operating a drop arm barrier?
Most drop arm barriers operate on 208V or 480V three-phase power, but models are available with alternative voltage options, including single-phase power, to accommodate different site needs.
How wide of an opening can a drop arm barrier cover?
Standard drop arm barriers typically cover clear openings between 12 to 24 feet, but custom configurations are available for wider access points if needed.
Are your drop arm barriers crash-rated?
Yes, we offer drop arm barriers that are crash-certified to ASTM and DOS standards, capable of stopping vehicles at speeds up to 50 mph depending on the model selected.
What type of crash-rated vehicle barrier system do you need?
AVB = Active Vehicle Barrier
1. Utilized for active vehicle entrances, sally ports, unmanned entrances
2. Wedges, bollards, sliding, rising or pivoting horizontal beams, integrated into gates etc.
3. Hydraulically, electrically, pneumatically, or manually operated
4. May be surface-mounted, shallow-mounted, or standard depth installation
SVB = Static Vehicle Barrier
1. Utilized for fence lines, permanently closed gate openings, temporarily closed gate openings
2. Cable-type barriers, bollards, berms, trenches, walls, street furniture, vegetation, concrete barriers, guardrails etc.

Operating times range from five to fifteen seconds, depending on the length and manufacturer of the barrier arm.
How quickly can a drop arm barrier be closed in Emergency Fast Operation?
Closing times range from four to seven seconds, depending on the length and manufacturer of the barrier arm.
What are the different types of drop arm barriers?
Drop arm barriers come in a variety of hydraulic and electric options with the ability to customize to certain specifications based on the unique needs of any given facility. They’re available in multiple opening sizes and have multiple crash-rating options.
What are drop arm barriers’ primary use?
Drop arm barriers provide crash-rated protection from vehicle-borne threats with a surface-set design, bypassing the need for excavation. This makes them ideal for safeguarding critical infrastructure, oil and gas, chemical sites, government sites - anywhere that foundation excavation is impractical.
