Supplier News TPC inventor Erlau marks 70 years Erlau’s tyre protection chains (TPCs) offer advanced all-round protection. A SMALL drawing registered by Erlau in 1943 marks a pivotal moment in the history of bulk materials handling. At that time, mining methods were changing as the lumbering steam shovels, rope operated excavators and horse-drawn rail tubs which had themselves superseded the pick and shovel, were being replaced by wheeled, hydraulic loading shovels and tipper-bodied trucks. Based on the technology recently developed for agricultural tractors, these new, highly-manoeuvrable, multi-tasking machines were already being used in operations such as sand and gravel extraction. Over the decades these loaders became larger, more sophisticated and standard equipment on many sites. Initially, because pneumatic tyres were easily damaged by abrasive or sharp materials, hard-rock miners found that, due to unacceptably high tyre replacement costs, they were denied the advantages of their soft-rock cousins. With new compounds and steel cords, tyre technology advanced to accommodate ever larger machines but the inherent flexibility of the tyres continued to make them vulnerable to harsh conditions. Already well-known for their round-link industrial chains, Erlau was inspired to adapt its snowchains to overcome the problem of premature tyre loss from heavy abrasion and sidewall damage and, thus were born the first, albeit crude, tyre protection chains (TPCs). Like all innovations, Erlau’s TPCs took time to perfect. As Erlau’s R&D worked closely with users of their TPCs to overcome the challenges of geology, environment and machine applications, more than 500 patents followed - registering refinements in link design, mesh geometry and advanced metallurgy. Once TPCs were established as a cost-effective solution for mining loaders, other applications quickly followed. Today, celebrating 70 years of tyre protection, Erlau TPC offers TPCs made from lightweight, energy-efficient, cost-effective alloys that are tough enough to absorb the most aggressive attrition and strong enough to repel sidewall piercing flints and slate. Nowadays, when Erlau TPCs can extend the working life of tyres by as much as 10 times and bring operators the added bonuses of assured plant availability and greatly reduced costs per loaded tonne, many owners are fitting Erlau chains to their wheeled loaders - from the smallest to the industrial giants. Erlau TPC chose bauma 2013 in Munich, Germany, to launch its 70 year celebrations. Erlau’s attention to quality and service has been rewarded with more than 65% of the world tyre protection market but this success has not made the company complacent. Ongoing investment in state-of-the-art production and assembly facilities, with 3 in Europe and 1 in South America, enables Erlau TPC to promptly fulfil large, whole-mine orders while the R&D department continues to create components that speed TPC installation and provide comprehensive protection for wheeled loaders, dozers, graders, scrapers, pipe-layers and haul trucks. As well as mining and quarrying, Erlau tyre protection and traction chains are found protecting tyres in tunnelling, pipe laying, scrap metal handling, demolition, steel-making, forestry and the military. Increasingly a standard fitment for haul trucks and soft-going offhighway, Terraplus is a lightweight traction chain with toothed links that give extra bite and safe travel over soft ground and ice-covered site roads. EASYLOCK, with its simple, patented, one-turn closure, re-invents the omega ring fastening to make TPC installation and removal fast, safe and economical. In a departure from their chain technology, Erlau’s SIDEFLEX adapts sophisticated memory polymers to bring the first cost-effective sidewall protection for haul-truck tyres. Embedded in the TPC sidewall, SMARTLINK’s RFID records and shares TPC service life. Downloaded to a PC, this information not only provides valuable management data but also emphasises Erlau TPC’s total confidence in its products. By making possible the widespread use of pneumatic-tyred loaders and trucks in mining and quarrying, this first link, which evolved into the ubiquitous accessory seen today, revolutionized materials handling across the entire spectrum of heavy-side industries. Without Erlau TPC’s invention ensuring tyre longevity, it is doubtful if the wheeled loading shovel would have become so successful and many handling operations would still be dependent upon the less versatile tracked machinery. 70 | ASIA Miner | May/June 2013
