How far must the counterweight guard extend above the pit floor?

The requirement for the counterweight guard to extend above the pit floor pertains to safety measures in elevator design. By extending 12 inches above the pit floor, it ensures that there is a sufficient barrier to prevent any accidental contact with the counterweight during maintenance or operation. This height is particularly important as it helps minimize the risk of injury to personnel working in or near the pit area, and it provides a robust safeguard against any potential faults that could lead to the counterweight moving unexpectedly. The 12-inch extension is a standard that promotes safety within the elevator system, ensuring that operational hazards are effectively mitigated. This is why the 12-inch height is mandated in regulations regarding elevator safety equipment.
