The assistance system that detects hazards before they arise
Linde Safety Guard
Safety when it matters most
What if people, their handling equipment and the infrastructure could communicate with each other?
Wherever industrial trucks are in use, a complex interplay between man and machine exists. The Linde Safety Guard is an innovative monitoring system which provides an early warning of potential hazards.
Wherever industrial trucks are in use, a complex interplay between man and machine exists. The Linde Safety Guard is an innovative monitoring system which provides an early warning of potential hazards.
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: 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 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.
always in the safe zone
Be it excessive speeds, staff members 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.
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.
The Linde Safety Guard uses warning zones 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, then 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. 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 minimises accidents between trucks and staff 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 staff with an accuracy of ten centimetres 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
The Truck Unit warns the industrial truck operator via LED lights and acoustic signals.
Portable Unit
The Portable Unit warns staff of approaching industrial trucks using acoustic signals, LED lights and vibration.
Sensors
Detect the modules carried by pedestrians and industrial trucks in the defined hazardous zones.
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.
Static Unit
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.
Zone Marker
The Zone Marker defines speed restriction areas.
Charger
The charger charges the Portable Unit inductively. The fully automatic activation provides optimum convenience for the operator.
And action: Linde Safety Guard in use
Smurfit Kappa LithoPac in Nybro, Sweden, specialises 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, the Linde Safety Guard was implemented. The system was fully adapted to the individual needs of the business and will be expanded even further in the future.
