Linde Safety Guard

What if people, their handling equipment and the infrastructure could communicate with each other?

Material handling operations like loading and unloading trucks can encounter potentially hazardous situations. Industrial trucks and staff working together in close proximity can be challenging and difficult to control. In the worst-case scenario, this can lead to injury or property damage.

Every aspect of any material handling application demands constant vigilance by all personnel involved: blind corners, low visibility areas and distracting noises are all ever-present safety risks in intralogistics and manufacturing working environments.

A Timely Warning: Linde Safety Guard

The Linde Safety Guard is an innovative monitoring system that increases safety for truck operators and pedestrians in the vicinity of the truck. Active advance warning in the event of potential hazards means that everyone involved can react immediately. Depending on the application and the equipment, the Safety Guard system warns of imminent danger via acoustic signals, flashing LED lights or vibrations. Hazards can then be dealt with before any physical injury or collateral damage occurs.

This unique safety system was developed by the start-up Comnovo, which was acquired by Linde Material Handling in July 2017. The system has been incorporated into Linde Material Handling's industrial trucks since early 2016. Since then, the system has proven itself across a wide variety of industries.

Wherever industrial trucks are in use, there exists a complex interplay between man and machine. This application is a perfect example of where Linde Safety Guard plays a critical role in keeping your team safe.

Always in the Safe Zone

Tailored Safety

The Linde Safety Guard system increases the safety of all staff involved in internal traffic. It can see around corners and through walls, reduces speeds automatically and can be programmed to suit any hazardous scenario.

All this is possible due to the Linde Safety Guard system being able to precisely determine the position of marked objects or staff with an accuracy of ten centimetres, and the fact that warning zones can be individually adjustable, helping to prevent false alarms.

Furthermore, a broadband radio signal in the 4 GHz range (UWB) helps to ensure reliability by eliminating interference from WiFi, Bluetooth or RFID.

  • Warning zones are established to prevent accidents:
    • Transmitters are positioned on industrial trucks, walls, racking and even carried by the staff themselves
    • This ensures rapid detection, early warning and avoidance of hazardous situations
  • If a pedestrian and a truck look likely to collide
    • Both the industrial truck and the pedestrian are warned simultaneously
    • A receiver in the truck indicates how many pedestrian staff are approaching the danger zone and from which direction
    • Pedestrians are warned by the transmitter they have on them
  • Speed restriction zones can be pre-defined and programmed:
    • This empowers the system to automatically reduce the truck's speed in these zones and also warns the truck operator
    • This minimises accidents between trucks and staff in areas like production, order picking areas and busy intersections

The system can be adapted to meet any safety requirements. It consists of individual modules, and can be tailored to the respective hazardous situation on individual sites.
