Advanced Technologies for Mission-Critical Operations

Six-Axis Heavy-Lift Design

The six-motor configuration significantly enhances flight power and stability, enabling the drone to carry heavy firefighting payloads such as extinguishing bombs, dry powder tanks, and water hoses. This design provides the necessary thrust for reliable operation in challenging fireground conditions.

Innovative Barrel Folding Design

The WK-1800 features a vertical six-axis folding structure that compresses the aircraft into a compact barrel shape for transport. This design reduces storage footprint, simplifies packing and assembly, lowers transportation requirements, and enables rapid field deployment.

Smart Battery & Long Endurance

Equipped with a high-capacity 66000mAh LiHV battery, the WK-1800 delivers up to 50 minutes of flight time on a single charge. The built-in intelligent power management system includes low-voltage alerts via the mobile app, real-time battery status monitoring, and enhanced safety features.

LIDAR Obstacle Avoidance System

The high-precision LIDAR system provides intelligent obstacle detection with ranging capability up to 100 meters. It can identify obstacles 2–20 meters ahead (adjustable) and automatically initiate braking to prevent collisions. This dual protection of obstacle avoidance and ranging ensures safe flight operations in complex environments.

30X Optical Zoom Camera (Standard)

The WK-1800 comes standard with a 30x optical zoom camera (1200MP, 4K 30fps) for long-range monitoring. This enables detailed observation of fire scenes and disaster areas from a safe distance, providing critical intelligence for developing effective rescue strategies.

Night Vision Targeting System

Equipped with a high-power aiming mirror and a high-frame-rate night vision camera, the system displays a targeting crosshair on the ground control APP, enabling precise remote fire extinguishing operations even in complex, low-visibility fireground conditions.

IP43 Weather-Resistant Construction

The closed modular design with IP43-rated protection ensures reliable operation in harsh environments—wind, rain, dust, high temperatures, and severe cold. This industrial-grade waterproof, dustproof, and anti-corrosion capability adapts to demanding rescue operation conditions.
