An elevator in a 10-story residential area in Kuala Lumpur, Malaysia, had been in use for over 8 years. It frequently suffered from landing door jams, incomplete car door closure, and repeated door opening/closing delays—issues that not only reduced residents’ travel efficiency but also posed safety risks. When the customer inquired about a solution via a cross-border platform, hoping to quickly replace the entire landing door and car door system, we responded within 24 hours to confirm that Sdyss Elevator would provide a full set of compatible accessories (including core components like door operators, door locks, and guide wheels) tailored to the elevator’s model.
To ensure precise accessory matching, we coordinated with a local cooperative technician who arrived at the customer’s site within 3 days. Using tools such as laser rangefinders and vernier calipers, the technician measured key parameters one by one—including landing door opening dimensions, car door track spacing, and door operator mounting hole positions—and synchronized the data to Sdyss’ production team. Sdyss launched an expedited production process, completing accessory customization and quality inspection within 48 hours. The accessories were shipped via international dedicated logistics and delivered to the customer’s designated location in just 4 days.
After the customer received the accessories, our engineers provided full video guidance to the installation team. During the process, a slight dimensional deviation was found between the original door operator bracket and the new accessories. We immediately offered remote guidance to adjust the bracket hole positions, and finally completed the installation and debugging of the entire landing door and car door system in only 6 hours. From the customer’s initial inquiry to the elevator’s return to normal operation, the total cycle was just 11 days—far shorter than the customer’s expected 15 days. The customer highly recognized the compatibility of Sdyss accessories and our efficient services.
