A1. The speed of the elevator is set based on numerous factors. Generally, the vehicle speed between floors in a hospital ward is maintained at 0.25 to 0.5 meters per second. This allows for the smooth transportation of non-urgent patients, preventing discomfort caused by excessive speed. On the lines connecting the emergency room, operating rooms, and intensive care units, we have equipped the elevators with high-speed medical stretchers operating at speeds of 1.0 to 1.75 meters per second, ensuring that patients can reach their destinations quickly within the critical rescue timeframe.

A2. Safety protection is integrated throughout the entire design. Firstly, the doors are equipped with high-precision optical curtain protection, which boasts extremely high sensing accuracy. Even if a very thin medical tube blocks the light, the door will immediately stop closing and reopen to prevent strangulation. Secondly, the braking system employs redundant design and multiple braking safeguards. If the primary brake fails, the backup brake will immediately take effect, ensuring that the vehicle can come to a smooth stop in any emergency situation, with the braking distance strictly controlled within a narrow range. Additionally, the elevator features various intelligent protection mechanisms for overloading, shutdown, and slipping, continuously monitoring its operational state and providing comprehensive protection for patient safety.

A3. For this type of requirement, some cargo elevator cabins can be customized with removable cabin top sections and cabin wall panels. When transporting extremely tall equipment (such as large angiography machines), the corresponding cabin top panels can be removed to increase vertical space. For transporting exceptionally long equipment (such as long rehabilitation training tracks), some cabin wall panels can be removed to expand the horizontal passage space. Additionally, the elevator control system is pre-set to a “large equipment mode.” In this mode, the operating speed is appropriately reduced, and the opening time of the doors is extended, ensuring that specialized equipment can safely and completely enter and exit the elevator.

A4. The hospital bed elevator is equipped with an emergency power supply system. In the event of a power outage, the emergency power will immediately come online to ensure the proper functioning of the lighting and ventilation systems within the elevator car, thereby preventing patients from being left in a dark and stuffy environment. Additionally, the elevator will automatically and slowly descend to the nearest floor, come to a smooth stop, and open the doors. Throughout this entire process, the system is meticulously controlled to ensure the safe evacuation of both patients and medical personnel.

A5. We have invested considerable effort into the noise reduction design of our elevators. The vehicles are equipped with materials that provide excellent sound insulation, effectively blocking mechanical noise during operation. Additionally, the drive system employs advanced silent technology, optimizing the design of motors and transmission components to minimize noise levels to less than 50 decibels during elevator operation. This volume is akin to a whisper and essentially does not interfere with patients’ rest or the tranquil environment of the hospital.
