The assistance system that detects hazards before they ariseLinde Safety Guard
Safety When it Matters Most
What if people, industrial trucks, and the infrastructure could communicate with each other?
Material handling operations like loading and unloading trucks can encounter potentially hazardous situations. Industrial trucks and personnel 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: The Linde Safety Guard
Linde Safety Guard is an innovative assistance system which increases safety for both truck operators and pedestrians in the vicinity of the truck. Active alarms triggered in the event of a hazard mean that everyone involved can react immediately. Depending on the application and the equipment, the Safety Guard system warns of imminent danger via acoustic warnings, 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.
Always in the Safe Zone
Be it excessive speeds, personnel crossing a truck’s path or low visibility: There are a multitude of reasons why accidents can occur while working with industrial trucks. The Linde Safety Guard’s system can be configured to monitor specific risks.
Wearable Safety: The Pedestrian Warning Band from Linde
The Pedestrian Warning Band is the latest innovation in the Linde Safety Guard System. It uses vibration, sound and light signals to warn its wearer of an approaching truck, ensuring safety during operations. With an accuracy of 10 cm and its ergonomic design, the Pedestrian Warning Band combines high safety with high wearing comfort. The Pedestrian Warning Band fits comfortably over certified high-visibility vests and is equipped with an intuitively replaceable battery. This allows it to be used in all environments, including multi-shift operations.
The Linde Safety Guard system increases the safety of all personnel involved in internal traffic. It can see around corners and through walls, reduces speed automatically, and can be programmed to suit any hazardous scenario.
The Linde Safety Guard uses warning zones to prevent accidents. Transmitters are positioned on industrial trucks, walls, racking, and even carried by the personnel themselves. This ensures rapid detection, early warning, and avoidance of hazardous situations.
If a pedestrian and a truck look likely to collide, then both the industrial truck and the pedestrian are warned simultaneously. A receiver in the truck indicates how many pedestrian personnel are approaching the danger zone and from which direction. The pedestrian is warned by the receiver. This also works through walls and racking.
Speed restriction zones can also be pre-defined and programmed, so that the system automatically reduces the truck’s speed in these zones and also warns the truck operator. This minimizes accidents between trucks and personnel in areas like production, order picking areas, and busy intersections.
All this is only possible because the Linde Safety Guard system is able to precisely determine the position of marked objects or personnel with an accuracy of 10 centimeters accuracy and the warning zones are individually adjustable. This level of precision also helps to prevent false alarms. Moreover, a broadband radio signal in the 4 GHz range (UWB) helps to ensure reliability by eliminating interference from WiFi, Bluetooth, or RFID.
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.

Truck Unit small
The Truck Unit small is attached to the forklift and communicates with stationary modules such as the Static Unit or the Zone Marker.
The Static Unit marks hazardous zones in critical areas such as access doors or low visibility intersections. This module warns others in the area via acoustic signals and LED lights.
The Zone Marker defines speed restriction areas.
The charger charges the Portable Unit inductively. The fully automatic activation provides optimum convenience for the operator.
Pedestrian Warning Band
In the event of danger, the Warning Band warns the pedestrians and the forklift drivers. Light and sound signals alert the band carrier about approaching trucks. The ergonomic design guarantees high wearing comfort.
And Action: Linde Safety Guard in Use
Smurfit Kappa LithoPac in Nybro, Sweden, specializes in offset printed corrugated packaging. They are one of the leading manufacturers of paper-based packaging in the world. At their plant in Nybro, forklifts and people work together closely at a rapid pace. Safety is a high priority. In 2021, Smurfit Kappa LithoPac implemented the Linde Safety Guard. The system was fully adapted to the individual needs of the business and will be expanded even further in the future.
