Needing a chain that would withstand use in the harsh environment of the asphalt industry, a mill in the Netherlands turned to Tsubakimoto for a solution


T


hanks to its high performance within harsh environments, the GT4 Winner


chain from Tsubaki is being used in applications which demand reliability, with one example being the asphalt industry. Here, the industry is under pressure to deliver fresh, hot asphalt to road paving companies, and lost production can have a significant impact on companies. In the Netherlands, for example, an asphalt mill had been experiencing problems with a 16B-1 drive chain that was being used on a conveyor for transporting raw materials. With the result being frequent periods of lost production and high maintenance costs, the company turned to Tsubaki for a solution. On investigation it was found that a lack


of lubrication reaching the bearing faces of the chain was causing chain elongation and failure. To overcome the problem, Tsubaki recommended the installation of its RS16B-1 GT4 Winner chain, and a trial period was carried out to test the results. The GT4 Winner is one of the most advanced chains that the company


produces, and it has features that are designed to reduce wear and chain elongation. Lube-grooved bushes hold oil at the point of contact which provides an internal reservoir for lubricant where the chain needs it most. The seamless and perfectly cylindrical bushes result in both better contact between the pin and bush and improved lubricant retention.


CHAINS UNDER TRIAL The trial included a KG-test comparison with two other premium brands of chain. According to the company, this test is one of the most effective ways of testing different chains in an equal environment as it ensures a fair comparison between different chain types. For this, a single length of chain is created using two or three different types. It is then left to run in-the-field and, once finished, is separated and re-measured to compare the degrees of elongation. As the chains are tested in real-life applications they are subjected to the rigours of the industry that they will perform in, with the results providing a


CONVEYING SOLUTIONS


The complex and highly automated mechanised systems in today’s food processing industry often pose handling challenges when transporting product from one operation to another, comments Wire Belt, the metal conveyor belt manufacturer. No universal standard exists for conveyor widths, belt types,


turning and positioning systems, or drive mechanisms; and the myriad of production component options often ignores specific product requirements such as weight, size, speed, degree of separation, and if it is fragile. To help, the company offers a number of options. Its Flex-Turn Conveyors, for example, are designed to assist manufacturers in turning their production line 90˚ to save footprint space; while the Ladder-Flex Conveyor can sort, converge or separate products while they are moving on a process conveyor belt. The Straight Conveyor, meanwhile, can be fitted with various options of conveyor belt, ensuring the versatility to satisfy most individual manufacturing requirements with both inclining and declining options available.

Installed at the asphalt mill, the RS16B-1 GT4 Winner chain is one of the most advanced chains that Tsubaki produces


competitor chains suffered from 2.2% elongation and the other from 1.51%, the company claims. The GT4 Winner chain, however, had only seen a 1.29% increase in length. This demonstrated that the GT4 Winner chain had 15% less elongation than the first premium brand and 35% less than the second. As Tsubaki advises replacement of a chain once elongation reaches 1.5%, both competitor brands had reached the end of their useful service life within 1000 hours. By installing the GT4 Winner chain, the customer has improved the service life of the drive chains, reduced the replacement costs and increased reliability and productivity. “It is important to consider the total life costs when specifying components such as roller chain which will be subjected to very real wear,” concluded Derek Mack, Tsubaki UK sales director. “A product that is a little cheaper to purchase may require twice the levels of in-service maintenance and still last half the time. GT4 Winner chain has been proven to last longer than any other chain on the market and requires minimal servicing once installed.”

CARRYING SYSTEM FOR RTG CRANES INTRODUCED


Designed for Rubber Tyre Gantry (RTG) cranes, the e-rover carrying system from igus is said to provide a safe and secure means of switching the RTG from diesel to electric power. This, the company explains, helps reduce fuel costs at ports and harbours. By using igus e-chains, this can carry up to three different types of media, including power and data, fibre optic cables and fluids. Features


include automatic coupling and uncoupling of the e-rover to the energy chains; and an internal mechanism allows it to compensate for horizontal and vertical offsets, ensuring it provides the RTG with an uninterrupted connection.
