The drop forged chains supplied by Bechtel are made of heat treated high grade alloy steel. These links can be equipped with plastic or steel scrapers. The following table shows various types of drop forged chains, together with the respective breaking loads and core/surface hardness.

The double drag link chains supplied by VAV Aandrijvingen B.V. consists of a combination of inner and outer links. The bush/pin connection between the links is available in a circlips version. The plastic scrapers are attached in the middle of the outer links. Besides, welded steel scrapers may be used for heavy-duty purposes. The following table shows the standard V.A.V. double drag link chains, stock.

The double drag link chains according to DIN are available in a circlip, a splitpin, or a revited version. The steel scrapers can be L-shape bent, welded and / or bolted with plastic profiles.

The sprocket of the drop forged chain consists of a body with interchangeable teeth segments. The following sprockets are available ex stock for chains with a pitch:

Double drag link chain Sprockets are with or without teeth (return sprockets) and wear-resistant due to the hardening on the teeth. These sprockets have a symmetrical hub and are divisible, making them easy to (dis) assemble. The following versions are available ex stock. Different dimensions are possible on request.

Our plastic flights are made of wear-resistant nylon and are flexible. As the chain is carried by the plastic flights, it eliminates the steel-on-steel contact, this will lead to saving energy and a considerable noise reduction. There are various kinds of flights available: Nylon, Nylon with Glassfiber reinforcement, Zytel and FDA-quality.

Plastic profiles are made out of different materials, such as: Nylon, PU, and UHMPE. These may be used as flights or as scrapers. The profiles are available in various different versions. This page shows the most common used models.

A variety of different scrapers are available for drop forged chains as well as for double drag link chains. Special-purpose types are available for horizontal, inclined, or vertical conveyors. In this context, the capacities are taken into consideration as well. Below please find some examples of steel scrapers.
