Elevator QKS9D Door Lock Box Hall Door Lock LSF9 300P Elevator Door Lock Device

Door lock QKS9 is a commonly used door locking device in Schindler elevators. The following is an introduction to it

Functions and Roles

• Safety Assurance
  As a key component of the elevator door locking system, the QKS9 door lock is used to lock the hoistway door and car door of the elevator, preventing the doors from accidentally opening during elevator operation and ensuring passenger safety. It allows the doors to be unlocked only when the elevator arrives at the accurate position and stops level, ensuring passengers can enter and exit safely.
• Electrical Interlock
  The QKS9 door lock also has an electrical interlock function. By connecting with the elevator control system, it can feedback the door lock status signal to the control system. The elevator can only operate normally when all door locks are properly locked and the electrical interlocks are closed. If a door lock opens abnormally, the elevator control system will immediately trigger the safety brake device to stop the elevator and prevent accidents.

Structural Features

• Mechanical Structure
  It is typically made of sturdy and durable metal materials, equipped with reliable mechanical latch hooks and latch devices that can withstand significant external forces, ensuring the doors do not open due to shaking or other external forces during elevator operation. The design of the latch hook and latch is carefully optimized for good wear resistance and fatigue resistance, enabling long-term stable operation.
• Electrical Components
  It is equipped with electrical components such as bridge-type contacts to achieve the electrical interlock function. These electrical components have good conductivity and stability, accurately transmitting the door lock status signals to the elevator control system. Meanwhile, the electrical components also have certain protective properties, adapting to harsh environments in the elevator shaft, such as moisture and dust.

Application Scenarios

• Commercial Buildings
  Widely used in elevators of commercial places like office buildings, shopping malls, and hotels. These places have high passenger traffic and strict requirements for elevator safety and reliability, which the Schindler QKS9 door lock can meet, providing a safe riding environment for passengers.
• Residential Buildings
  Commonly used in elevators of high-rise residential buildings. Ensuring the safety of residents' daily elevator rides is a key task of residential elevators, and the stable performance and safety functions of the QKS9 door lock can provide reliable protection for residents' travel.
• Industrial Buildings
  Also used in freight elevators of some industrial plants, warehouses, and other places. Freight elevators need to transport goods frequently, requiring high durability and reliability of door locks, and the QKS9 door lock can adapt to such high-intensity usage environments.
