What is the limit of speed for lifts?

• A. Chair Specifications
• B. Maximum Speed
• C. Friction Machines
• D. Inspection and Testing

Answer: (B)

The limit of speed for lifts is the maximum travel speed that an elevator is allowed to operate at. This ceiling is set by the manufacturer and relevant safety codes to ensure safe performance. When a lift stays within this maximum speed, it can accelerate and brake reliably, maintain safe stopping distances, and coordinate with door timing so passengers can board and alight safely. Pushing beyond this limit would increase dynamic forces, risk longer stopping distances, and accelerate wear on equipment.

The other options don’t apply to speed limits: chair specifications aren’t part of elevator performance, friction machines are unrelated to elevator speed control, and inspection and testing concerns verifying performance rather than defining the allowable speed.
