GATPOR laser distance sensors have already been supplied in batches to leading domestic elevator manufacturers for home elevator positioning systems. In transparent-shaft home elevators, the media-free, wear-free, and hidden-installation advantages have been widely recognized by the market. Customer feedback shows that the laser solution makes elevator operation more stable, stopping more accurate, and maintenance lower, while allowing transparent shafts to achieve the intended open and elegant design that magnetic-tape installation previously limited.

Laser ranging technology applied to home elevator speed monitoring and overspeed braking replaces traditional mechanical governors with non-contact measurement, eliminating risks such as rope slip and failed governor counterweight action at the source. Electronic signal triggering provides shorter response time and immediately activates progressive safety gear for smooth braking during overspeed. Braking deceleration is controlled between 0.2g and 1.0g, ensuring safety while avoiding harsh impact. Annual maintenance cost is greatly reduced, keeping safety continuously online.

From stopping only after impact to stopping before impact, GATPOR’s non-contact laser distance judgment solution gives elevator car-bottom collision protection true active safety capability, protecting equipment, passengers, and maintenance cost.

GATPOR elevator U-shaped leveling door-zone photoelectric switches integrate laser technology and functional-safety thinking. Multi-channel redundancy provides reliable and stable door-zone leveling position detection.
