Heavy industry

In the realm of heavy machinery, the use of components made from technical plastics is becoming increasingly commonplace. These plastics are reliable and durable materials with a low coefficient of friction.

Technical plastics are used in machine parts such as ball bearings, rolls, slide rails, gearwheels, and chain guides. These materials offer excellent absorption of vibration and resistance to chemicals while still remaining considerably lighter than metals.

In heavy industry, all components of a production system must function reliably and meet high quality standards. All parts that require maintenance must function flawlessly between the scheduled maintenance operations.

Plastics have been used in heavy industrial applications for decades now, allowing us to accumulate a wealth of information and extensive hands-on experience of their suitability in this sector. Plastics require only minimal lubrication, if any. This in itself creates savings. In addition, there are numerous other beneficial properties that are unique to plastics.

Testing

The European Union’s Machinery Directive pertains to work machines. Under the directive, a machine equipped with a cabin must be designed so as to protect the driver from falling and flying objects and to prevent any injuries caused by the vehicle overturning.

Before a machine may be placed on the market, its cabin must undergo thorough testing.

  • The term ‘ROPS’ is used with reference to the rollover protection system and its testing.
  • ‘FOPS’ refers to the falling-object protection system and its testing.
  • ‘OPS’ is used in reference to testing of the operator-protection structures.

Standards pertaining to cabin safety tests
ISO 3471, ISO 3449, ISO 8082, ISO 8083, ISO 8084, SAE J1040, and SAR J 1084
