In environments prone to causing corrosion, chains made in part or entirely of stainless steel can be used.
To withstand even more demanding conditions, the chains can be made of acid resistant steel.
APPLICATIONS
Heating plant conveyors
If the loads on top of the chain are heavy and the chain is moved on a sliding sprocket, the chain can be equipped with thicker-than-normal side plates.
Another advantage of hardened side plates is that they have a higher-than-normal breaking load.
APPLICATIONS
A-type welded conveyor chain
Sawmill log tables
Various reception conveyors
It is often necessary to join different attachment structures to the chain. Instead of welding, the attachments can be attached with bolts directly to the side plates or the attachment fittings.
Maintenance can be easily performed on the attachments in place, and the same attachments can be reused on new chains.
APPLICATIONS
Heating plant conveyors
Our selection includes extremely heavy lifting chains for, e.g., lifting dam doors in hydropower plants and waterway canal systems.
Our completely self-sufficient manufacturing allows us to produce chains from a range of different raw materials. Our typical raw materials include various stainless and acid-resistant steels.
The pin distance in our chains is typically between 100 and 300 mm.
APPLICATIONS
Hydropower plant dam doors, canals, plate
bundle chains, pin chains
Toothed chains featuring toothed side plates are used in feed-ing the mill and in transporting the pre-cut timber.
The dimensions of the toothed chain models produced by Lapua Chains are based on the roller chains designed for power transmission applications. These chains' mechanical structures have been developed so that they are the best, most suitable choice for use on such conveyors.
Our range includes chains with each of the following pitches: 1” (16 B), 1.5” (24 B), and 2” (32 B).
APPLICATIONS
Sawmill conveyors
