Industrial Heavy-Lift Multirotor Drone

Heavy-payload multirotor performance depends on more than the rated lifting capacity. The airframe, propulsion layout, power system and flight control all have to remain balanced when the aircraft is carrying a substantial load. The YIHANG factory's YH-70 Industrial Heavy-Lift Multirotor Drone uses a 2480mm wheelbase, six-rotor configuration and carbon fiber composite structure to support its 70kg-class payload capability.

The foldable airframe reduces the transport footprint for field deployment, while the integrated FOC power system, battery and BMS are configured as part of the aircraft platform. Selected payload mounts, flight parameters and battery configurations can also be customized according to project requirements.

Key Advantages

1. 70kg Payload with 17-Minute Full-Load Endurance

The YH-70 Industrial Heavy-Lift Multirotor Drone is rated for a maximum payload of 70kg, with a stated endurance of up to 17 minutes at full load. This configuration provides lifting capacity for selected equipment, supplies and industrial cargo in locations where conventional transport is difficult.

The six-rotor layout distributes lift across multiple propulsion units to support controlled flight during heavy-payload operations.

2. Up to 45 Minutes of No-Load Endurance

Without payload, the YH-70 provides up to 45 minutes of flight endurance under the stated conditions. The lighter configuration is suited to missions where longer airborne time is more important than maximum lifting capacity.

Actual endurance depends on battery configuration, payload, altitude, weather and flight conditions.

3. Foldable Structure for Field Deployment

With a 2480mm wheelbase and a foldable airframe, the YH-70 can be reduced to approximately 1370 × 1195 × 1350mm for transport. The reduced transport footprint can simplify deployment between operating sites.

4. FOC Power System for Heavy-Load Operation

The FOC high-efficiency power system is designed to provide precise motor control and power management during heavy-load flight. A plateau compensation function is specified for high-altitude operation, supporting power-system performance under changing operating conditions.

5. RTK Positioning

The YH-70 Industrial Heavy-Lift Multirotor Drone combines GPS, BeiDou, Galileo and GLONASS with an industrial RTK module. The listed static positioning accuracy is ±0.05m.

This positioning configuration supports accurate route planning, fixed-point operations and aerial data collection where positioning performance is important.

Payload & Configuration

The YH-70 Industrial Heavy-Lift Multirotor Drone can be configured with different payload mounting solutions according to the weight and dimensions of the equipment being carried.

YIHANG supports customization of payload brackets, mounting structures, flight parameters and battery configurations. Selected accessories and mission equipment can also be integrated after evaluating their weight, dimensions, power requirements, mounting method and aircraft balance.

This configuration approach allows the same airframe to be adapted to different cargo and industrial requirements without changing the core aircraft structure.

Applications

Mountain Logistics

The YH-70 can transport selected heavy equipment and supplies to remote mountain areas where road access is limited, reducing dependence on difficult ground routes.

Emergency Supply Delivery

The aircraft can support delivery of relief materials and equipment to disaster-affected areas when roads or other ground transportation routes are disrupted.

Firefighting Support

With compatible equipment, the YH-70 can support selected firefighting operations involving the transport or deployment of suitable fire-suppression payloads and auxiliary equipment.

Industrial Inspection

The aircraft can be configured with compatible inspection equipment for power-line, pipeline and other infrastructure monitoring where longer flight time is required.

Survey & Mapping

The RTK positioning system can support aerial data collection and mapping operations when paired with suitable survey equipment.

Environmental & Safety Systems

The YH-70 Industrial Heavy-Lift Multirotor Drone is specified with Level 7 wind resistance, a maximum operating altitude of 5000m, and an operating temperature range of -20°C to 60°C.

Built-in safety functions include loss-of-link return-to-home, low-battery return-to-home and landing, and mission resume. These functions are designed to support controlled operation during extended industrial missions.

Manufacturing & Support

YIHANG integrates key systems of the YH-70, including the airframe, power system, batteries and BMS, as part of the overall aircraft configuration.

For commercial projects, support includes payload bracket modification, flight-control tuning, battery configuration and OEM branding. Trial units are available, with bulk-order support, one-year warranty and technical assistance available according to project requirements.
