 Standardisation – ISO
Our chains are manufactured in accordance with the International Organisation for Standardisation (ISO) This guarantees full replaceability or the combining of conveyor chains from different manufacturers. The Swedish standard SMS 2083, the German DIN 8167, the French NF E26-106 and the Finnish SFS 2380 all now conform to ISO/R 1977.
 Production method
A good conveyor chain must be designed in such a way that it can cope with heavy wear and large shock loads. These properties are achieved as a result of both pins and sleeves being surface hardened and secured as firmly as possible to the link plates. Thanks to our modern and partially automated production technology, we can supply durable chains of even quality. Two methods are used for the assembly of pins and sleeves:
- Roller riveting
- Automatic welding
 Roller riveting is a cold riveting method where considerable force is used to hammer the pins against the side plates. This method provides an extremely strong joint that can withstand considerable lateral forces.
When welding, CNC controlled automatic welding machines are used, guaranteeing welds of a very even quality.
Quality supervision
We invest a great deal in ensuring that our products maintain a high level of quality and operational reliability. Quality supervision at the factory starts with an acceptance inspection of the raw material and finishes with a final  inspection prior to delivery to the end customer.
In addition to our own measurements and tests, we also rely on tests carried out by the VTT Technical Research Centre of Finland and other laboratories in the sector. The chains are checked fully in accordance with the standard SFS 2380.
Product development
Product development has had a central position in the company’s operations right from t he outset. Developments have taken place in collaboration with the chain’s users, suppliers or raw materials and various research institutes. By investigating various raw materials and trying out various alternatives, we are constantly striving to achieve more operationally reliable products. As regards manufacturing methods and the level of automation, the factory has developed into one of the most modern in Europe in our sector. Targeted investment activities guarantee that the achieved level is maintained and further developed.

s In modern materials handling, stringent demands are placed on those machine elements included in transport devices. We produce conveyor chains of various types for the mechanical engineering industry, the forestry and pulp industry, the chemicals sector, the food industry, etc. The chains satisfy the very high demands our customers stipulate regarding e.g. breaking strength, impact resistance, press fitting and weldability. The chains are produced with a high level of precision according to Swedish and international standards, and can be adapted to the needs of the individual customer.
Developed in collaboration with conveyor designers, maintenance and operating personnel from timber handling within wood processing industry. The profile chain is special developed for timber conveyors, where the most important requirements have been extremely strong mountings comprising pins and sleeves in the side plates and between pins and sleeves, as well as good breaking strength of the chain. The profile chain’s pins and sleeves are therefore welded into the side plates, which in practice has proven to be the best mounting method. The chain is produced from weldable material, which means that the driver and angle brackets can be welded to the side plates without pre-heating.
