Synopsis
Nibav Lifts USA offers smart home elevators with built-in overload alerts that instantly notify users if weight limits are exceeded. This intelligent safety feature ensures smooth operation, prevents damage, and delivers peace of mind for families using modern residential elevators.
What It Is
- The smart overload alert is a safety feature that monitors the load on a home elevator continuously and automatically stops operation of the elevator if the total load exceeds an approved amount.
- Rather than allowing for an unsafe and possible strain on a mechanical system and/or passenger safety, the elevator identifies an overload condition and disables travel mode until the total weight is less than the approved amount.
- Nibav USA home elevators have the electronic load-sensing technology incorporated into the elevator control system. The precise sensors are located beneath the cabin floor as well as within the structural frame of the elevator.
- They are constantly measuring the total mass of a passenger or passengers and carried items. If the weight measured exceeds the elevator’s rated capacity, a visual and audible alarm is triggered, and the system will lock out any movement commands.
Thus, the elevator will always be operating within its design limits, providing protection for both the passengers in the elevator and the mechanical systems of the elevator.
Why It Matters
Operating an elevator beyond its rating is one of the most significant causes of mechanical wear, misalignment, and safety incidents. In a traditional elevator that does not have the ability to monitor the load, users may not know they are overloading the cabin, which can lead to:
- Increase in the stress on the drive systems
- Uneven or jerky movement
- Premature wear on the components
- Risk of stopping between floors
Nibav’s smart overload alert prevents these risks before they develop into unsafe operation. This type of elevator will never try to run when the conditions are unsafe, which is especially important in home-type environments where grocery carts, luggage, wheelchairs, or multiple people are being carried into the elevator, to ensure that your elevator remains safe for all passengers and remains functional and reliable over time.
By keeping the elevator always working in the optimal range specified by design and engineering, the costs of maintenance related to the performance and reliability of the elevator in the long term will be significantly reduced.
Who can benefit from this type of elevator?
Family homes and multi-family homes are great locations for smart overload alerts because of the possibility of passengers unintentionally exceeding the maximum load capacity of the elevator when travelling with multiple passengers.
Homes that contain seniors or disabled persons using wheelchairs should take special care to ensure the use of a smart overload alert because wheelchairs add additional weight to a cabin that must be safely maintained.
Also, luxury homes may want smart overload alerts because of the increased numbers of passengers who frequently visit their home.
A home with a consistent use of heavy items, such as grocery bags, luggage, or household products, can benefit from the use of a smart overload alert to ensure the weight of all items being transported in a cabin does not constantly exceed cabin load limits. The weight of all items being transported in a cabin is important in protecting the structure of the elevator system from significant wear. Thus, the use of a smart overload alert is a great investment for homeowners who wish to maintain the reliability of their elevator over time.
Technical specification of the smart overload alert
Nibav USA’s smart overload alert is built into the digital control system and sensor network of the elevator.
1. Load sensors
High-precision strain gauges and pressure sensors located beneath and within the supporting structure of the cabin measure:
- Weight of the passenger
- Load of items
- Weight of cabin
The load sensors continuously transmit the measurement data to the elevator’s central control processor.
2. Real-time monitoring
The elevator control system is continually monitoring and comparing the actual cabin load measurements with the safe load capacity of the elevator. The elevator control system uses this information to detect overloads immediately when they occur.
3. Emergency alarm and lockout
If the cabin load exceeds the maximum allowable load on the elevator:
- An audible alert sound
- A visual alert indicator located on the control panel will be illuminated.
- No command to operate the elevator will be allowed.
The system will not operate until the cabin weight is below the maximum safe load.
4. Integration with pneumatic drive
Because Nibav elevators use vacuum pneumatic systems, accurate and reliable information regarding cabin weight is required to sustain the appropriate pressures and smooth motion produced by the elevator. The smart overload alert maintains the cabin within the lift and pressure design specifications of Nibav engineers.
5. Automatic reset feature
Once the excess weight has been removed from the cabin, the system will automatically clear the overload alert and allow operation to resume.
Frequently Asked Questions
1. Will the elevator operate if overloaded?
No, the smart overload alert will prevent the elevator from operating until the cabin load is below the maximum allowable load.
2. How does the elevator calculate the amount of cabin weight being measured?
Nibav elevators contain load sensors that continuously monitor and calculate the total weight of the cabin at any time.
3. Is this type of elevator safe for wheelchair users?
Absolutely, the system was designed to be safe and to accommodate the use of mobility devices without exceeding maximum allowable cabin weight limits.
4. Is the performance of the elevator affected due to the use of smart overload alerts?
No, the use of smart overload alerts helps to ensure that the correct air pressure is maintained, thereby ensuring smooth operation and providing a reliable ride. It has no effect on the quality of the ride.
5. Is the smart overload monitoring feature standard on Nibav USA elevators?
Yes, smart overload monitoring is a component of the overall safety architecture of all Nibav elevators and is included in the agency design of the elevator.
