The Trust We Place in Machines
You step into a small metal box and press a button. Then, you wait to be lifted hundreds of feet into the air. This act requires an immense amount of trust. You trust the cables not to snap and the brakes to hold. Therefore, safety is not just a feature; it is the entire point of the machine. In Bangladesh, where infrastructure can be unpredictable, your elevator must be a fortress. Fuji passenger lifts are designed with this specific reality in mind. They offer layers of protection to keep you safe.
The Automatic Rescue Device (ARD)
Power outages are a daily reality in our lives. Load shedding strikes without warning in summer. If the power dies while you are between floors, panic sets in naturally. However, the Automatic Rescue Device (ARD) prevents this nightmare. It is a battery-powered backup system. When the main power cuts, the ARD wakes up instantly. It moves the lift to the nearest floor and opens the doors. Because of this, you are never trapped in the dark. It is the most essential safety feature for Dhaka.
Infrared Light Curtains
Old elevators used mechanical “safety edges” that had to hit you to stop. That was painful and slow. Rather, modern Fuji lifts use infrared light curtains. These are invisible beams of light that cover the entire door height. If a child’s hand or a stray saree breaks even one beam, the door reopens immediately. It does not wait to touch you. Therefore, it prevents crushing injuries effectively. This “invisible wall” is a standard standard for passenger safety today.
The Overspeed Governor
Gravity is a constant force that wants to pull the cabin down. If the cables were to fail—which is incredibly rare—the lift would accelerate. However, the Overspeed Governor is watching for this exact moment. It is a mechanical speedometer that works independently of the electricity. If the lift drops too fast, the governor locks a steel cable. This action triggers massive clamps on the guide rails. These clamps bite into the steel rails and stop the car dead. It is the ultimate fail-safe.
Overload Sensors
People often try to squeeze “just one more person” into a crowded lift. This puts dangerous stress on the motor and brakes. Therefore, Fuji lifts come with intelligent overload sensors. These sensors weigh the cabin in real time. If the weight exceeds the limit, the lift refuses to close the doors. It sounds a loud buzzer to alert everyone. The lift will not move until someone steps out. This protects the machine from straining itself to death.
Emergency Intercom and Alarm
Imagine you are stuck and your phone has no signal. You feel isolated and scared. Therefore, every Fuji lift includes an emergency intercom system. A simple press of the “Bell” button connects you to the security desk or the machine room. This connection is a lifeline. It tells you that help is coming. In modern systems, this can even dial a programmed mobile number. You are never truly alone in the box.
Buffer Springs
The “pit” is the very bottom of the elevator shaft. If the control system fails completely and the lift goes past the bottom floor, it needs a soft landing. That is where the buffers come in. These are heavy-duty springs or hydraulic pistons sitting on the ground. They act like a giant shock absorber. They catch the cabin and absorb the impact energy. While you hope to never use them, they are there as a last resort.
Fireman Switch
Fire is a terrifying prospect in a high-rise building. You are taught never to use a lift during a fire. However, firefighters need them to move equipment up quickly. Therefore, Fuji lifts have a “Fireman Switch” in the lobby. When activated, the lift ignores all calls and goes straight to the ground floor. It opens the doors and stays there. This allows firefighters to take control manually. It prevents the lift from opening on a burning floor.
Door Lock Monitors
The elevator shaft is a deep, dark hole. Falling into it is fatal. Therefore, the doors on each floor have complex mechanical locks. The lift cannot move unless every single door is locked tight. An electrical circuit runs through all the locks. If a door is forced open by even an inch, the circuit breaks. The machine stops instantly. This prevents the terrifying scenario of a lift moving with open doors.
Emergency Stop Switch
Sometimes, you need to stop the lift immediately from inside. This might be due to a medical emergency or a strange noise. The control panel features a red “Stop” switch or button. Pressing it cuts the power to the motor and applies the brake. The lift halts right where it is. While it is rarely used, it gives passengers a sense of control. You can stop the machine if you feel unsafe.
Phase Failure Protection
Our electrical grid in Bangladesh sometimes loses a “phase.” This means one of the three power lines goes dead. If a motor runs on two phases, it burns out quickly. Therefore, Fuji control panels have phase monitoring relays. If the incoming power is bad, the lift shuts down safely. It protects the expensive electronics from bad electricity. It saves you from a costly repair bill.
Automatic Return to Base
Smart lifts know when they are not being used. You can program a Fuji lift to return to the ground floor (or “base”) after a period of idleness. It parks itself there with the doors closed. This is actually a safety feature too. It ensures the lift is ready at the main exit point in case of an emergency. It also reduces wear on the system by preventing unnecessary hunting.
Anti-Nuisance Feature
Children love to press every button in the elevator just for fun. This wastes time and energy. Therefore, modern Fuji controllers have “anti-nuisance” logic. If the weight in the cabin is light (one person) but five floor buttons are pressed, the system cancels the calls. It assumes a prank is happening. This keeps the lift available for serious users. It prevents the frustration of stopping at every empty floor.
Terminal Limit Switches
What happens if the lift forgets where the top floor is? It might try to crash into the roof. To prevent this, there are physical switches at the top and bottom of the shaft. These are called “Terminal Limits.” If the lift passes the top floor by a few inches, it hits this switch. The power is cut immediately. It is a brute-force method to stop the lift from going too far.
Conclusion
Safety is not an accident; it is engineered. A Fuji passenger lift is a collection of systems watching over each other. From the invisible light curtains to the heavy steel brakes, every part has a purpose. Therefore, when you buy a lift for your building in Bangladesh, do not ask just about the price. Ask about the safety features. A safe lift is the foundation of a happy building.
