Elevating Safety with Advanced Elevator Protection Systems
OSG UNIT ASSY (Speed sensor cum over speed limiter)
An over speed governor device monitors the speed of the elevator. When the lift exceeds its rated speed, the over speed governor triggers the safety gear system, mechanically locking and halting the rope, stopping the lift to move.
SAFETY GEAR ASSY
The safety gear assembly in elevators plays a critical role in ensuring passenger safety by preventing the elevator from free-falling in case of emergency or mechanical failure, such as a breakage of the suspension ropes or loss of control in the elevator system.
DOOR SENSOR:
The primary function of a lift door sensor is to detect obstruction in the passage of the closing doors, preventing the doors from closing. It protects passengers from injury and reduces the risk of damage to the lift. Advance sensors use a series of infrared beams to create a light curtain, which can help streamline lift operation and reduce unnecessary stoppages.
DOOR CLOSURES:
Automatic door landing is operated by a motorized system that automatically opens and closes the doors when the elevator reaches a floor or is ready to move. They are controlled by motor, operator, sensor, interlocks and timers to ensure smooth, safe operation.
HOISTWAY DOOR LOCK:
The primary purpose is to prevent the hoistway (shaft) doors from opening if the elevator car is not aligned with the landing. This avoids exposing the open shaft, which could lead to severe accidents. The hoistway doors cannot open unless the elevator car is exactly at the designated floor. The lift cannot move unless the hoistway doors are fully closed and locked.
CARTOP BARRICADE:
The car top fall hazard barricade is designed to protect the perimeter of the lift car top. According to IS standards, the barricade height must be maintained to ensure optimal safety. This safety feature is especially crucial during maintenance procedures, as it minimizes the risk of accidents in the confined and elevated spaces of a lift shaft.
PIT BUFFERS:
The primary purpose of a lift pit buffer is to absorb shock and protect passengers in the event of an emergency descent. If a lift is over-travelled and impacts the buffer, it slows down, ensuring a controlled stop.
HOISTWAY SAFETY SWITCHES:
Limit switches are essential safety devices in lifts that prevent them from traveling beyond their designated floors. These switches should be installed at both the top and bottom floors.
CARTOP INSPECTION ASSY:
The cartop inspection assembly is mounted on top of the lift car and serves as a control panel for technicians to perform maintenance and inspections. It prevents the lift from moving accidentally during inspections
EMERGENCY RESCUE (Electrical Rescue Operation)
An emergency rescue operation is a procedure performed to safely evacuate passengers from a lift in the event of a malfunction or power failure. It allows trained personnel to manually operate the lift and bring the car to a safe level for passenger evacuation.
