ZERO-COMPROMISE PROTECTION
Safety Is Not an Option. It Is Our Standard.
Every Otiva vertical mobility installation incorporates multiple redundant mechanical, electro-mechanical, and electronic safeguards protecting passengers through every stage of motion and rest.
ENGINEERING ANATOMY
Core Elevator Safety Systems
Engineered with fail-safe principles where any single component anomaly immediately halts cabin movement safely.
1. Door Safety Systems (Infrared Curtains)
Full-height multi-beam infrared light barriers projecting invisible beams across the cabin entrance. If an entering passenger, child, or object interrupts any beam, door closure is instantly halted and reversed without physical impact.
2. Electro-Mechanical Door Interlocks
Dual mechanical and electrical locks on every landing entrance. The elevator drive circuit cannot energize unless every single landing door is fully closed and mechanically latched, preventing any possibility of open-shaft hazards.
3. Emergency Alarm System
Audible emergency sirens mounted both on top of the cabin and within the building lobby. Backed by independent battery power, this alert operates continuously even during total utility power failure.
4. Emergency Cabin Lighting
Autonomous LED emergency light fixtures connected directly to trickle-charged standby batteries. Illuminates instantly within milliseconds of grid disconnection, keeping passengers calm and reassured.
5. Overload Protection Sensors
Precision load cells mounted beneath the car platform or rope hitch. When rated payload is exceeded, a buzzer sounds, the cabin display warns ‘OVERLOADED’, and doors remain open until safe weight is restored.
6. Overspeed Governor & Safety Gear
A purely mechanical centrifugal governor in the machine room monitoring car speed via an independent steel cable. If downward speed exceeds rated thresholds, it triggers hardened steel wedges that clamp the guide rails, halting the car mechanically.
7. Dual Independent Electro-Magnetic Brakes
Traction machines utilize dual independent spring-applied, electrically released brake arms. Either brake shoe possesses sufficient mechanical torque to decelerate and hold a fully loaded elevator independently.
8. Hoistway Limit & Terminal Safety Sensors
Multi-stage directional limit switches installed at top and bottom shaft terminals. If the elevator fails to decelerate at terminal landings, mechanical limit switches physically cut motor and brake circuits.
9. Emergency Communication (Intercom)
Hands-free two-way voice communication connecting trapped passengers to the building security control room and external emergency service hotlines with push-to-talk simplicity.
10. Automatic Rescue Device (ARD)
High-capacity battery inverter system that activates automatically during unexpected power outages. It intelligently determines the least loaded direction, crawls the cabin smoothly to the nearest landing, and parks with doors wide open.
Statutory Standards & Engineering Compliance
In strict compliance with company policy, Otiva Elevators designs elevator safety circuits in accordance with applicable Indian Standards (such as IS 14665 elevator specifications) and global engineering codes. Detailed factory component test sheets, brake drop certificates, and rope test mill certificates are provided with every installation.
Specific third-party certifications, municipal inspectorate licenses, and standards compliance documents:
