Product Specifications

Functions and Roles

Safety Assurance

As a key component of the elevator door locking system, the QKS9 door lock securely locks both hoistway and car doors during elevator operation. This prevents accidental door openings and ensures passenger safety by only allowing door unlocking when the elevator reaches the correct position and stops level.

Electrical Interlock

The QKS9 door lock features electrical interlock functionality that communicates door lock status to the elevator control system. The elevator operates normally only when all door locks are properly secured. If any door lock opens abnormally, the safety brake system immediately activates to prevent accidents.

Structural Features

Mechanical Structure

Constructed from durable metal materials with reliable mechanical latch hooks and latch devices designed to withstand significant external forces. The optimized latch design ensures excellent wear and fatigue resistance for long-term stable operation.

Electrical Components

Equipped with bridge-type contacts and electrical components that provide reliable conductivity and stability. These components accurately transmit door lock status signals while offering protection against harsh elevator shaft environments including moisture and dust.

Application Scenarios

• Commercial Buildings: Widely used in office buildings, shopping malls, and hotels where high passenger traffic demands superior elevator safety and reliability.
• Residential Buildings: Commonly installed in high-rise residential elevators to ensure safe daily transportation for residents.
• Industrial Buildings: Suitable for freight elevators in industrial plants and warehouses, providing the durability and reliability needed for high-intensity usage environments.
