Just like airbags in cars, elevator buffers are the last line of defense in passenger safety.
When ropes break, braking force is insufficient, or the control system fails, buffers absorb the impact to prevent the elevator car or counterweight from hitting the shaft bottom or top — protecting both passengers and equipment.
📍 Where They’re Installed
Typically mounted in the pit of the shaft, directly under the car and counterweight.
⚙️ Types of Buffers:
🔹 Energy-Consumption Buffers – e.g., Hydraulic Buffers, suitable for higher-speed elevators
🔹 Energy-Accumulation Buffers – e.g., Polyurethane Buffers (v ≤ 1.0 m/s), compact and efficient
📐 Key Selection Parameters
Hydraulic Buffers
✔ Nameplate information
✔ P+Q value (Car weight + Rated load)
✔ Rated speed
✔ Self-height & Stroke
Polyurethane Buffers
✔ Diameter
✔ Height
✔ Mounting hole distance
✅ Safe, reliable, and engineered for precision — elevator buffers are the invisible guardians of vertical transportation.
