Ryson Spiral Conveyor Automatic Chain Tensioner reduces maintenance down-time and prolongs the life of the spiral. All Ryson Spirals are supplied with an automatic chain tensioner. It is part of our effort to help our customers reduce their total cost of ownership.
All Ryson Spirals are equipped with an automatic chain tensioner that ensures the chain is in proper tension at all times. The chain will stretch over time – especially during the break-in period of the first 200 – 400 hours of operation. – The chain tensioner takes up the slack, eliminating the need for frequent chain shortening, but the chain must be shortened when the chain stretches beyond the tensioner’s capacity to compensate. This may be required several times during the first year of operation, depending on the length of chain, load weight and chain speed.
The chain needs to be shortened when the tension bar is at or below 0 degrees (horizontal). A sensor will detect when the chain has stretched to the point where the chain needs to be shortened.
It is important to keep the chain in tension at all times. In fact a poorly tensioned chain, along with less than ideal integration are the leading causes of premature spiral wear.
Chain shortening of a Ryson Spiral is a simple process that can be done in a few minutes, reducing your production down-time. Shortening of the chain can only take place at the in or outfeed sprockets and can be done most conveniently at the low level. There are several master links in the chain-slats and are clearly marked.
