IEC TO REBUILD AERIAL TRAMWAY SYSTEM FOR MECHEL BLUESTONE, INC. Interstate Equipment Corp. (IEC) of Pittsburgh, PA has renegotiated a contract with Mechel Bluestone, Inc., new owners of the former Bluestone Coal Group, to rebuild an existing aerial tramway system for the company's premium quality hard coking coal operations. Located in Keystone, West Virginia, near Bluefield, thel project is designed to completely refurbish an existing tramway that was engineered and built by IEC for previous owner, Eastern Gas and Fuel Associates, in 1957. The new contract includes a rebuilt loading terminal, including new rails,tail sheave and spillage hopper system, as well as new pivot tower, breakover tower and discharge terminal. Although situated in some of the most rugged terrain in rural West Virginia, the existing Keystone tramway system is proof of the design ingenuity, construction quality and low maintenance and operating cost of IEC tramway systems. For instance, after 50 years of service, many of the track cables installed in the 1957-built system are still in solid working condition today. This exceptional cable life is due to the fact that the original towers featured pivot approach rails for smoother breakover, less wear and longer cable life. In addition, many of the original steel structural components have proven as sound as the the day they were installed and, with minor refurbishing, will provide many more years of continued service. The Mechel Bluestone, Inc. project represents the latest in a 105-year legacy of revolutionary tramway designs that have helped earn IEC recognition as an industry leader. The company also offers a diverse line of innovative barge and material handling products, specialized engineered products, and design, engineering and installation services for customers in the power generation, petrochemical and metal/mining industries who routinely transport bulk materials by barge over inland waterways. Backed by over a century of continuous operating experience, IEC strives to benefit its customers by providing a wide range of proven alternatives to increase productivity and handling capacity, reduce energy consumption and minimize operating costs.

Designed and manufactured by Interstate Equipment Corporation (IEC), Pittsburgh, PA, these unique new vessels allow AmerenUE to effectively offload coal barge deliveries in record time…saving as much as 50% of the time previously required to perform the same operation. At the Rush Island Power Station, a typical 1500-ton coal barge, that previously required 1-hour and 20-minutes to unload, can now be offloaded in as little as 40 minutes…50% less time than the previous method. Similar savings have also been realized at AmerenUE’s Sioux Plant, where the IEC shuttle barge has helped reduce offloading time by as much as 1-hour and 10-minutes per barge…40% less than the previous time required. In fact, these results have been so impressive that one AmerenUE senior spokesman was prompted to state “the IEC shuttle barge has been the single most important improvement we’ve made at both plants as far as improving unloading efficiency.” The custom-designed shuttle barge and access system supplied by Interstate allows operating personnel to accommodate two coal barges at a time connected to the shuttle. As the first barge is fully offloaded, the unloader can immediately begin offloading the second, and the empty barge can be switched out for another loaded barge from the fleet, while unloading continues. Switch-out delays and downtime are minimized, and the unloader production cycle is rarely interrupted. The system also reduces manual labor normally required to connect and disconnect cargo barges, and safety conditions for operating personnel are greatly improved, especially during hazardous conditions such as high water or ice storms. AmerenUE is a subsidiary of St. Louis-based Ameren Corporation. The Ameren companies serve 2.4 million electric customers and almost one million natural gas customers in a 64,000- square mile area of Missouri and Illinois. Interstate offers a diverse line of barge and material handling products, specialized engineered products, and advanced design/engineering services for customers in the power generation, petrochemical, and metal and mining industries who routinely transport bulk materials by barge over inland waterways. The company’s innovative products and technology benefit customers by providing a wide range of proven alternatives to increase productivity and handling capacity, reduce energy consumption and minimize operating costs. · IEC  Contracted to Replace Haul Cable at Johnstown Inclined Plane The Cambria County Transit Authority (CamTran) has contracted IEC to replace the 2" haul cable on the Johnstown Inclined Plane November 2004.

Controls Volume. Saves Money.  IEC's new engineered Mass Flow Control System is designed around  the proven Pebco Mass Flow Feeder, a simple, compact unit designed to reduce maintenance costs and production interruptions by minimizing dust and spillage during material transition from the surge hopper to conveying equipment. This versatile feeder provides improved volumetric feed rate control by positioning the hydraulically-powered clamshell style gates to the desired opening. It also insures that flowing material is always fed directly onto the centerline of the conveyor belt, regardless of feed rate. Because of its efficient design and smooth operation, the Pebco Mass Flow Feeder featured in the IEC System requires less power consumption than many conventional units, yet still generates ample power to operate multiple feeder units simultaneously. And with fewer components and no vibrating parts, this compact unit operates quite effectively at a relatively low noise level. Built of heavy-duty carbon steel channel, angle and plate, contact surfaces of the Mass Flow Feeder are lined with type 304 stainless steel to reduce friction and maximize material feed and consistency. Featuring a feeder opening size of 36" x 48", the hydraulically operated feeder gate controls the flow of bulk materials up to 2,000 STPH. By combining a substantial range of construction features with many proven operating and performance benefits, the new IEC Flow Control System offers many substantial maintenance-saving and cost-reducing benefits. So if you have experienced material dust and spillage problems, along with a series of untimely production interruptions, maybe its time to consider a new IEC designed Mass Flow Control System with a Mass Flow Feeder. In fact, we can help evaluate your operation, and provide a detailed proposal, including a complete design and supply package that is taillored to your specific production operation. Mass Flow Feeder “NEWSMAKERS” The Mechel Bluestone, Inc. facility is a continuous 20-car aerial tramway system designed to convey coal refuse at a rate of 350 tons per hour.
