Chain manufacturer iwis ‘raises the standard’ in Britain’s capital

The Woolwich ferry provides one of the few available crossings of the River Thames in east of London, linking the north and south circular roads across the river. The ferry service bridges at Woolwich Crossing were recently overhauled and chain specialist iwis drive systems Ltd. from Tipton, UK, provided new roller chains for the North and South side bridge lifting systems. The River Thames, which passes through Britain’s capital, has seen a free ferry service based at Woolwich Crossing near Greenwich since the mid 18th century by act of Parliament. The ferry terminals are based on the north and south banks and allow passengers travelling by foot or by vehicle to cross the river. Each year the ferries carry over 1 million vehicles and 2.5 million foot passengers with a service operating every 10 minutes, running 12 hours per day, 363 days every year. The passengers embark at each side on one of two bridges or “link spans” which raise and lower according to tide and time, allowing a safe passage onto and off the ferry. The current operator, Briggs Marine Contractors, is contracted by Transport For London (TFL) to manage a major overhaul of the complete ferry system to increase the reliability and resilience of the service and maintain the ferry service for many years to come. Briggs contracted Amco to undertake the major works associated with the link span refurbishment which has included the replacement of the complete hoisting mechanism.

Elite baler chains

Elite baler chains

With its agrisystems agricultural machinery centre, chain manufacturer iwis presented drive chains for harvesters at the recent Agritechnica 2015 in Hanover, Germany. The new additions to the Elite range have been developed specially for use in round balers and, like all Elite agricultural machinery chains, are exceptionally wear-resistant. To meet OEM manufacturers’ differing requirements, the chains are available in various configurations.   Since agricultural machines operate outdoors, the chains used in them are exposed to harsh conditions such as dust, dirt, cold and damp. Moreover, after long idle periods in the winter their reliability is repeatedly put to the test. Developed especially for round balers of harvesters and available in a range of configurations, iwis’ Elite-branded chains are highly versatile, with the ideal design available for almost any make or model. The increased plate width improves the chains’ durability compared to other types. The pins receive a special heat treatment for improved wear resistance and the material combination of pin and bush has been optimised. The chains are factory-lubricated with a high-performance German lubricant.   With agrisystems, chain specialist iwis operates an agricultural machinery centre that is dedicated to meeting the special requirements of the agriculture industry. During the harvest season flexible production and dedicated stock levels ensure that spares are readily available for fast delivery. Together with OEMs, iwis agrisystems develops and implements tailored drive solutions. “The agricultural machinery sector does not consist solely of large, corporate mutlinationals. Numerous medium-sized specialists – often family-owned companies – are also working their share of the market”, explains Thomas Cohrs, Key Account Manager at iwis agrisystems in Sontra. “Our technical consulting...

Constant development keeps chain at forefront of technology

Chain is one of the unsung heroes of the engineering world. Although a long established technology, it continues to develop and improve, so remains one of the most efficient methods of power transmission available today. Greg Sharp, Engineering Manager at Tsubaki Chain in Nottingham, looks at some of the recent developments and shows how they appeal to new markets. The only time most people come into contact with chain is when they are carrying out maintenance on their bike. However, as engineers know, chain is used in almost every industrial process and is, in fact, a critical component in high performance machines and systems the world over. Like many engineering products, chain comes in a range of qualities and prices; for demanding applications better quality chain is usually a sound investment. A popular choice of high performance chain is ‘lube-free’, such as Tsubaki’s ‘Lambda’ range. This uses special oil impregnated bushings which ensure the bearing surfaces are continuously lubricated to minimise wear. The advantages of lube-free chains can be summed up as: reduced maintenance; no costs associated with manual lubrication; longer life, leading to less frequent replacement and the associated costs; no purchasing of lubricants or lubrication systems; no unforeseen downtime due to chain breakages and therefore higher long-term productivity; reduced risk of contaminating products, machines, floors; and generally increased environmental acceptability. An example of how Lambda chain improved the performance and profitability of a production machine was on a large paper log accumulator at a world class hygiene paper company. This is used to marshal paper logs before they are presented to a saw so that they can...
