Masada Technology provides better service with the latest control system.
Make the operation run smoother and the failure rate lower!
Easy modification, low price, full transparency
Peace of mind maintenance – leave your maintenance to Masada and be at ease.
Use intelligent data to identify and perform big data analysis to achieve low-carbon and energy-saving performance.
Improve efficiency and green cycle benefits through energy feedback.

Energy savings

When the elevator is unoccupied after a period of time, the lighting and fans in the cabs will automatically stop. The displays inside and outside the cabs will be dimmed to save energy, and will be turned on again when the cabs is in use.

LED lighting

Replace traditional lighting with high-efficiency, energy-saving, environmentally friendly, low-temperature, low-carbon, safe, and durable green energy-based light sources.

Wrong button cancelling

When passengers accidentally press the wrong button, they can use the “continuous pressing” action (pressing the same button twice) to cancel out the button they pressed.

Canceling the elevator when the elevator is called but is traveling in the opposite direction

When the elevator changes directions, the system will cancel the floor requests that are in the opposite direction, and the elevator is going to save power and reduce useless stopping.

Prank signal light canceling

When there are no passengers in the cabs and multiple floor buttons have been pushed on the control panel as a prank, the system will automatically determine this as an error and cancel all existing elevator stopping requests.

Masada’s three mottos are “attention to detail, care, and attentiveness.” We make a before and after comparison when we exchange parts and conduct maintenance. After each maintenance we make a detailed maintenance report on the nine major elevator safety parts. Rest assured that Masada provide the best service quality!

Elevator functions

Earthquake Sensor

When an earthquake occurs, the system quickly detects the main vibration source, and works with the elevator control system to make the running elevator stop at the nearest floor so that passengers can leave the elevator.

Energy Feedback Device

The energy fed back by the elevator is fed back to the power grid through the AFE, and is no longer lost through resistance. The generated recycled power is fed back to the building’s power grid to supply the building’s electricity. Energy savings can reach up to 35%.

ARD for Power-off Protection

When the elevator stops suddenly, the system automatically switches to emergency mode for emergency signals and backup power supply. The elevator that enters the standby power supply mode will go to the nearest floor and open its door, allowing automatic rescue.

Outdated elevator decoration affects the overall image.





Modern decoration design and high-quality materials can be matched according to the style to enhance the overall texture.


Elevators are characterized by high power consumption and poor operating efficiency, which is manifested in early products. Reduced voltage start wastes a lot of power.





Comfortable and stable cabs operation greatly improves passenger safety and ride experience.


The elevator shakes when it starts and stops at a floor. The cabs floor is uneven and passengers can easily trip, resulting in an uncomfortable elevator ride.





Comfortable and stable cabs operation greatly improves passenger safety and ride experience.


Most parts of the elevator have been discontinued. Maintenance is difficult and malfunctions occur.





A long-term, sufficient, and timely supply of parts for elevators is available throughout their entire life cycle.


When the service life of an elevator exceeds 15 years, it has higher failure rate and poses a safety hazard to passengers.





Effectively reduce potential hazards such as having people trapped, a sudden rise of an elevator cabs, and cabs slipping, so that managers, residents, and visitors can feel at ease.
