Delivery Drone with 300 kg payload Debuted at CPSE

From October 28 to 31, the 20th China Public Security Expo (CPSE) opened grandly at the Shenzhen World Exhibition & Convention Center, gathering over 1,100 exhibitors from more than 150 countries and regions. On this cutting-edge stage focused on digital security and intelligent technology, ZHT AERO showcased multiple heavy lift drone models, becoming the highlight of the low-altitude economy zone and attracting significant attention from visitors.

Powerful yet compact. Intelligent yet modular.

With the strong research foundation of Tianjin University and extensive UAV development experience, ZHT AERO believes excellence is born from precision design. By combining cutting-edge engineering with advanced academic insights, we have made modularity a core principle of our drones, providing agile, reliable, and versatile UAV solutions.

Conventional heavy-lift drones are bulky and rigid, often needing vans or trucks for transport and complex on-site assembly—making operations slow and labor-intensive

The latest drone features a coaxial quadcopter design with eight propellers, capable of lifting up to 300 kg, while the packed fuselage occupies just 1 m3. Modular separation allows it to fit into any standard small box truck. This reduces the dependency on specialized transport vehicles, significantly lowering transport thresholds and costs, and greatly improving operational mobility.

Even fully loaded with 300 kg, the drone delivers 22–30 minutes of flight time. Safety is built into every aspect of its design, featuring redundant power systems, real-time voltage and current monitoring, soft-start technology, and emergency response protocols. More than just a powerful tool, it is a reliable partner you can trust in the field.

Capable of carrying a 300 kg payload, this all-electric cargo drone is poised to revolutionize the heavy-lift sector, enabling faster operations and easier transport. It is now in the final testing stage—watch for upcoming updates!

Designed for heavy-lift operations from 20 to 160 kg, KEEL Max continues the KEEL series’ legacy of quick-release structure and lightweight construction, offering outstanding agility and long flight endurance. KEEL Max is powered by 46xx large cylindrical battery cells (e.g., 4695 ）, delivering strong power output and long-lasting energy support. With a 100 kg payload, it can achieve up to 30 minutes of flight time.

The KEEL series integrates “Pandora Quick-Release” interface system, supporting plug-and-play operation for 30+ types of payloads—including pods / gimbal, terrain -following radar, sensors, and more—making KEEL Max a multi-functional drone for cargo delivery, firefighting and rescue, logistics, disaster relief, and maritime supply

KEEL Plus is a 30 kg-class modular heavy-lift drone with tool-free detachable arms, landing gear, and other components, allowing single-person deployment in 2 minutes. At just 12 kg for the frame & power module, it is lighter than peers while achieving a maximum payload of 30 kg. Reinforced carbon fiber and aerospace-grade aluminum provide an optimal balance of strength and weight.KEEL Plus uses the 46-series cylindrical battery system, ensuring abundant and lasting power.

It is ideal for emergency response, logistics, research testing, and offshore supply missions. The frame is adjustable to accommodate 36–43 inch propellers for versatile operations.

ZHT AERO emphasizes that true innovation lies not in accumulating technical specifications, but in applying technology to address real-world challenges, enhance industry efficiency, and reduce operational costs. We continue to deepen its presence in the UAV sector, offering comprehensive, one-stop solutions—from drone frame and power system packages to fully integrated UAV platforms—delivering reliable, efficient, and flexible aerial operation solutions to users across various industries.
