What is the maximum closing speed for power-operated arms?

• A. Closing Speed
• B. Force Resistance
• C. Obstruction Devices
• D. Capacity Plate

Answer: (A)

Closing speed is the rate at which a power-operated arm can move from open to closed. This safety parameter limits how quickly a pinch point can close, helping to keep energy behind a potential contact low and reducing the chance of injury if someone is nearby. Knowing the maximum closing speed allows designers and technicians to ensure the arm’s movement is slow enough to be safe in the event of incidental contact. The other terms refer to different safety concepts: force resistance describes how much force the mechanism can exert or withstand, obstruction devices are sensors that stop motion when something blocks the path, and capacity plate lists the equipment’s rated capacity.
