ROCK products • NOVEMBER 2014 30 MATERIAL HANDLING & CONVEYING EQUIPMENT & TECHNOLOGY Legg Co. Offers 'Made in U.S.A.' Conveyor Belt Legg Co. announced a new program called FLEX‐LEGG to supply conveyor belting that is made in the U.S.A. that meets RMA2 standards for less demand‐ ing applications such as conveying sand and gravel. The FLEX‐LEGG belting is available in five dimensions with a safety factor of 10:1. "Legg Co. is committed to providing a high quality product to the belting in‐ dustry and has worked diligently to come up with a standard program for this type of application. We believe that our customers will like the new pro‐ gram as it is made in the U.S.A.," said Christoph Seeger, market director for ContiTech Conveyor Belt North America. The FLEX‐LEGG product will be shipped within two business days and can be cut to standard widths to make ordering much easier. "Our customers will have more flexibility and do not need to carry as much inventory for these types of products – we take care of that," added Seeger. Legg Co. is part of the Continental con‐ veyor belt group and has been serving the needs of a variety of industries by provid‐ ing not only conveyor products, but tech‐ nology‐based solutions, since 1939. Legg Co., Martin Secondary Belt Cleaner Designed for Easy Maintenance Martin Engineering's secondary con‐ veyor belt cleaner is engineered to im‐ prove performance and reduce maintenance time, even as average belt speeds and loads continue to increase. The Martin SQC2S Cleaner features in‐ dividually cushioned tungsten carbide blades for effective cleaning without risk to the belt or splices. The new design forms a single sealing edge that maintains steady, adjustable pressure. Patented rubber buffers main‐ tain the cleaning pressure throughout the blade's life, while deflecting suffi‐ ciently to allow splices to pass without harm and ensuring compatibility with re‐ versing belts or those that experience backup at shutdown. Moving parts are zinc plated to resist seizing or rusting. "The blades conform to the belt profile, adjusting individually to deliver continu‐ ous contact across the belt," explained Dave Mueller, senior product specialist at Martin Engineering. "In a perfect world, bulk materials would load uniformly, wearing the blade evenly, but that rarely happens. By having multiple segments attached to a single rigid assembly, the tension can be maintained and adjusted accurately, quickly and safely." The rugged construction is engineered to withstand punishing conditions, such as high belt speeds, high‐impact trans‐ fers and high tonnage loads. Designed for a maximum belt speed of 1000 fpm (5.08 m/sec), the cleaner is suited for belt widths from 18 to 96 in. To match the requirements of specific ap‐ plications, the unit features straight 5.91‐ in. individual blade sections or 3‐in. individual blade sections, attached to a sturdy square mainframe. Replaceable urethane blades are color‐coded according to their continuous temperature rating, ranging between ‐40 to 350 F (‐40 to 177 C). Tungsten carbide tips can be specified for normal, acidic or high‐impact condi‐ tions. The rubber wear strip is supplied in continuous lengths up to 100 ft. Blade removal and replacement is a sim‐ ple operation on the SQC2S by removing the lock pin from the main assembly and sliding out the cartridge. The lock pins are a key component to Martin Engineer‐ ing's "no‐reach design," which allows workers to conduct their lockout / tag‐ out procedure more safely. Martin Engineering, www.martin‐‐finder
