OUR EQUIPMENT

In order to be able to fulfill a wide variety of specific missions in a secure, effective and efficient manner, we at HLDUS have equipped ourselves with a range of tools to ensure that this objective is achieved. To this end, we have chosen to rely, whenever possible, on off-the-shelf solutions already available on the market.

However, the solutions offered by the main suppliers have not always met our requirements. It has been then when we have decided either to make adaptations to these devices (such as, for example, the addition of a combustion engine to hybridize an electric drone in order to increase its autonomy) or, if the situation has recommended it, to develop our own solutions from scratch (such as the design and development of advanced drone command centers with which to operate UAS from adapted vehicles on the move).

Below, we are going to make a brief presentation of some of our work tools, which allow us to fulfill highly demanding missions that require very high levels of safety and quality.

MOBILE DRONE COMMAND CENTER

In order to develop our drone operation to capture all types of data beyond the visual range from a moving vehicle, a cornerstone of our efficiency in the inspection of linear infrastructures that has allowed us to inspect and scan more than tens of thousands of kilometers of power lines in Spain and abroad, HLDUS has developed our Mobile Drone Command Centers.

For this purpose, we have all-wheel drive vehicles that allow our professionals to go into the most demanding environments, being them the desert or forest tracks. These vehicles also have ergonomic and adapted workstations inside so that both the pilot and the camera operator can work safely and efficiently while the vehicle is moving.

Thanks to this tool we can perform rapid deployments and optimize aircraft flight time, so it is especially useful for technical inspections of linear infrastructures and security and surveillance or search and rescue missions.

T-DRONES 1500 ENHANCED + CAMERA INTEGRATION

The 1500 is a heavylifter hexacopter from T-DRONES with great features that allows us to carry our CAMI integration mounted on a Gremsy gimbal and composed of RGB, IR and UV cameras for thorough inspections of electrical installations. By mounting a visual camera we can obtain high definition images and videos, an ultraviolet camera for partial discharge and corona detection and, together with a thermal camera for hot spot detection and thermal monitoring on a three-axis gyro stabilizer, carry out a complete inspection in a single flight.

Even so, in order to increase its working autonomy, HLDUS has decided to equip it with an internal combustion system: a two-stroke twin-cylinder gasoline engine that allows us to keep the system in flight for more than two hours.

In addition, in order to avoid engine overheating in extremely hot environments such as the Arabian desert, this engine is liquid cooled. This integration has been carried out by our specialists as an improvement on our first version, which operated in the Kuwaiti desert, successfully inspecting more than 30,000 kilometers of high-voltage power lines.

Thanks to this equipment, we can perform missions requiring high flight autonomy, such as surveillance operations, search and rescue or technical inspections.

Main technical specifications:
   Maximum take-off weight: 24.9Kg
   Hybrid system (electric and gasoline)
   Maximum range: 150 minutes
   Maximum flight altitude: 6500m
   IP 55
   Wind resistance: 13m/s
   Temperature: -15 to 50ºC

DJI MATRICE 350RTK

This equipment is well known for its versatility. It has a high flight time, robust transmission, omnidirectional obstacle detection, IP55, hot-swappable batteries, customized payloads for RGB and thermal inspection, LiDAR and audiovisual productions.

It presents a very good resistance to inclement weather and thanks to its interchangeable gimbal allows us to use it in technical inspections, photogrammetry, surveying, surveillance or search and rescue operations.

Main technical specifications:
   Maximum take-off weight: 9.2Kg
   Operating frequency: 2.4, 5.1 and 5.8GHz
   Maximum flight altitude: 7000m
   Wind resistance: 12m/s
   Maximum flight time: 55 minutes
   IP55
   GNSS: GPS, GLONASS, BeiDou, Galileo
   Temperature: -20 to 50ºC

DJI INSPIRE 3

DJI's Inspire series is a benchmark in the world of audiovisual drones. Thanks to its performance, the quality of its optimized optics for cinema, the possibility of dual control and its agility, it is the ideal tool for multimedia productions.

In addition, its maximum speed has been increased to 10m/s, it has centimeter positioning by RTK module, omnidirectional obstacle detection and hot swap battery replacement.

Main technical specifications:
   Maximum take-off weight: 4.31Kg
   Operating frequency: 2.4, 5.1 and 5.8GHz
   Maximum flight altitude: 7000m
   Wind resistance: 12m/s
   Maximum flight time: 25 minutes
   GNSS: GPS, BeiDou and Galileo
   Temperature: -20 to 40ºC

DJI MAVIC 3 ENTERPRISE

The Mavic 3 Enterprise series is the flagship in portability. This equipment is extremely portable but that does not mean that it is not capable of doing professional work. At HLDUS we have the inspection focused models of the Mavic 3, the 3T (Thermal) and the 3M (Multiespectral).

The difference between the 3T and the 3M is the gimbal that loads the aircraft. While the 3T is an ideal tool for last-mile technical inspections thanks to its RGB and thermal camera integration, the 3M, thanks to its multispectral camera, is tremendously useful for work related to precision agriculture or forestry monitoring.

Main technical specifications:
   Maximum take-off weight: 1.05Kg
   Operating frequency: 2.4, and 5.8GHz
   Maximum flight altitude: 6000m
   Wind resistance: 12m/s
   Maximum flight time: 38 minutes
   GNSS: GPS, GLONASS, Galileo
   Temperature: -10 to 40ºC

DJI MINI 4 PRO

Despite its small size, this tool allows great flexibility for working in urban environments. Thanks to its class C0 marking and weight of less than 250g, as well as its ability to get as close to buildings as necessary and safe as possible, it speeds up operations and coordination in urban environments. On the other hand, its ability to take photography and videos both horizontally and vertically provides additional flexibility when creating content for social networks.

Main technical specifications:
   Maximum take-off weight: 0.249Kg
   Operating frequency: 2.4, 5.1 and 5.8GHz
   Wind resistance: 10.7m/s
   Maximum flight time: 34 minutes
   GNSS: GPS, BeiDou, Galileo
   Temperature: -10 to 40ºC

AUTEL EVO MAX 4T / 4N + AUTEL EVO NEST

The future of drones inevitably involves drone nests or docks. From these infrastructures, which can be installed in remote terrain but are also relatively portable, the drone can be available when needed. Always ready for work, protected from inclement weather, it can be operated remotely.

Thanks to this tool we can perform recurring missions in the same space such as technical inspections or surveillance or patrol missions, but also allows us to perform linear inspections integrated in our mobile units.

With the portability of a foldable drone and thanks to its interchangeable gimbal, the Evo Max series allows to perform technical inspection, security and surveillance missions even in environments with GNSS denial of service. Among other relevant technical features, the Evo Max can be operated from an Autel Nest, which also allows us to integrate it into recurrent operations mentioned above.

Main technical specifications:
   Maximum take-off weight: 1.89Kg
   Operating frequency: 2.4, 5.1 and 5.8GHz
   Maximum flight altitude: 4000m
   Wind resistance: 12m/s
   Maximum flight time: 42 minutes
   IP43
   GNSS: GPS, GLONASS, BeiDou, Galileo
   Temperature: -20 to 50ºC

HANDHELD GIMBALS & ASSORTED CAMERAS

In HLDUS we are specialized in the handling of drones and other unmanned vehicles, although we also have tools for taking pictures and videos at ground level. For example, our Sony Alpha 7R integrated in a Ronin-M stabilizer, which allows us to record stabilized shots.

On the other hand, we also have other handheld gimbals for other more compact cameras such as the Sony RX0, RX 100 or even action cameras like GoPro for informal handheld recording, but guaranteeing image stabilization with mechanical 3-axis gimbals.

In conclusion, HLDUS is not just another drone service provider but we also have the inventiveness and experience to find the right solution for any mission. Do not hesitate to contact us to transform your company's results through custom-designed solutions.
