Which is a general requirement for automated gates under ASTM F2200?

• A. Gates must be painted red
• B. Gates must be balanced so they do not open or close on their own when disconnected
• C. Gates must be solar-powered
• D. Gates must have a manual locking mechanism only

Answer: (B)

When automating gates, keeping the gate balanced is crucial for safety. The standard requires that a gate be balanced so it does not open or close on its own when power or the control system is disconnected. This ensures predictable manual operation and prevents the gate from drifting or moving unexpectedly during power outages or maintenance, reducing the risk of injury. In practice, this balance is achieved with counterweights, springs, or proper counterbalance geometry so the gate stays in a stable position when unpowered. The other options—paint color, solar power, or a manual locking mechanism only—aren’t universal safety requirements of this standard, which focuses on preventing uncontrolled movement and ensuring safe, controllable operation.
