ProSafe machine guarding
Machine protection with a system

The safety guards for machines are divided into different machine protection classes depending on their use.

• According to use into movable and fixed safety guards,
• By material into steel safety guards or aluminum safety guards,
• According to function into barrier grilles and safety light protection grilles.

At the same time, there are certain requirements for machine safety guards or safety guard systems. They must fit the machine in terms of their dimensions and, if necessary, ensure easy access to it with the aid of doors. As a machine guard, the stability must be able to withstand the forces that are likely to be generated by falling parts in the machine hall or the ejection of machine parts. Its design and the distance to the machine must prevent accidental penetration by the operator (DIN EN ISO 13857).

Compliance with the applicable standards and safety regulations for machine protection is monitored by recognized expert organizations such as TÜV. In German companies, a safety specialist must be appointed to monitor compliance with the standards. Safety fences in production plants are comprehensively planned. They must be able to withstand a wide range of accident scenarios.

For effective accident and personal protection, machine safety barriers or safety barrier systems are used wherever machines or vehicles move. For the most part, systems with protective grating can be found in warehouses and logistics centers. In addition, protective grilles are used where moving parts cause hazards, even if they themselves are permanently installed. The safety gate systems are often only one part of the overall safety concept, which also includes prohibition signs and, increasingly often, light barriers. The latter cause an emergency shutdown of the machine if an operator gets too close. However, this measure does not protect against accidents caused by parts falling into the machine or parts being ejected from the machine. For this reason, machine guards or safety fence systems remain indispensable.

Their use is necessary at these points, among others:

• Conveyor belts
• Room dividers for warehouses
• Turbine halls
• Operator cabins (e.g. for cranes)
• Enclosures for production lines
• Room dividers for industry
• Protective grilles on logistics vehicles
• etc.
  

Our systems with protective grilles are made of metal profiles, which enables their modular design. They also have doors with tamper-proof suspensions.

They can be installed as stationary or mobile units. Their variants can be assembled and dismantled by a single person. The mesh widths can vary. A common size is 20 x 100 mm with 3.0 mm wire thickness. The standard finish should be deep black, but other colors are often used.

Our standard color is RAL 9005 deep black, as recommended in the Machinery Directive. We also have frames and frameless elements in our range.

A practical example would be the protective grille around a turbine in a power station.
This rotates at 3,000 rpm during normal operation, resulting in very high forces. However, the danger is less during normal operation than during start-up after a general overhaul (or during initial commissioning), namely when running through the critical speeds (several ranges below 3,000 rpm).

It is true that the turbine has a fixed housing which nobody can reach into and which is also intended to prevent turbine blades from being ejected. However, if the turbine does not pass through a range of critical speeds quickly enough when starting up, an imbalance occurs which can lead to a turbine blade or wheel coming loose and the part being thrown out with a force that even the housing could not withstand.

In this case, the next barrier would be the mesh partition Smartsafe, a corresponding protective mesh system or a suitable crash test protective mesh. Ask your protective grille for machinery manufacturer!

Machine guards improve efficiency in your company. They ensure safe working conditions and prevent employees from unintentionally entering danger zones. A well-planned machine safety fence keeps production areas free from disruption and reduces the risk of accidents. As a result, machines run without interruption and productivity increases.

High-quality safety fences can be used to clearly separate work areas. This makes organization easier and ensures smooth processes. Employees know exactly where they can move around and machines work without unexpected downtime. An efficient system saves time and reduces maintenance costs.

As an experienced safety fence manufacturer, AnVa GmbH develops durable and flexible solutions. Our machine safety fences can be adapted to any environment and help to keep operations safe and efficient. This protects your machines, your employees and your entire production process.

Machine guards must meet strict specifications to ensure safety. Clear rules apply in the EU. The most important of these is the Machinery Directive 2006/42/EC. It ensures that machine guards reliably protect against hazards and at the same time enable simple operation.

The standards EN ISO 14120 and EN ISO 13857 are also relevant. They specify the requirements for height, stability and minimum clearances. Only tested industrial safety fence solutions meet these safety standards and prevent accidents caused by unintentional access to machinery.

AnVa relies on certified quality. Our machine guards comply with all applicable standards and offer maximum safety. They are robust, flexible to use and easy to install. They ensure safe and smooth operations in your company. With standard-compliant safety solutions, you avoid downtime and comply with all legal regulations.
