MATERIAL HANDLING CONVEYING Rubber Disc Return Rollers Pneumatic Single Rivet Driver Flexco���s Pneumatic Single Rivet Driver, designed for use with Flexco SR fasten��� ers and installation bases, speeds installation by up to 33 percent. The driver fea��� tures a dual handle for bal��� ance and ergonomic gripping, a heavy���duty drive rod for high���quality splices, and pneumatic driving power for a robust installation. A single trigger���pull per rivet saves both time and reduces worker fatigue. Collated rivets with wash��� ers and a specially de��� signed steel guide block assure that each trigger pull contributes to a con��� sistent splice. ���The Pneumatic Single Rivet Driver really takes the guesswork out of rivet driv��� ing to give users a uniform, long���lasting splice every time,��� said Patrick Mukushina, product man��� ager at Flexco. ���The tool al��� lows for more compression of the fastener plates, which results in a smooth and consistent splice that is compatible with conveyor components.��� The air���powered, heavy��� duty tool is built to last in even the most abrasive con��� ditions and is protected by a portable carrying case that also makes it easy to transport. Flexco, Rubber Disc Return Rollers from Elite Roller Manufacturing feature four tapered roller bearings (two in each hub) for unrivaled smooth, true operation and a service life that is up to three times longer than traditional two���bearing roller designs, according to the company. In addition to significantly longer service life, this patented ���quad bearing��� de��� sign withstands more severe applications than traditional rollers. ���Customers from a wide variety of industries report that their Elite Rollers last up to three times longer than traditional rollers,��� said Elite President Bill Schiering. ���Whatever the material handling application, we can tailor a roller to suit the particular requirements. Made with universal shafts, and 5���, 6��� or 7��� in. diameters, these products fit any manu��� facturers��� brackets. They are ideal for abrasive and corrosive environments, in��� cluding use in mining, aggregate materials handling, power plants and others. In addition to longevity, the patented Elite design allows the re���use of the axle assem��� bly, yielding a significant savings over re��� placing entire idler assemblies. Because ROCKproducts ��� MARCH 2013 Elite Rollers are with standard shell thick��� ness of 3���16���in. and �����in. Standard rollers in��� clude �����in. bearings, while heavy duty rollers are equipped with 1��������in. bearings. They are available for belt widths of 18��� to 96���in. An inner support tubes ensures that hubs are independent of each other for smoother operation and longer life. Stain��� less steel shafts are also available for more corrosive applications. Elite Roller Manufacturing, Superior Swing Axle TeleStacker Modified for Faster Setup Superior Industries��� engineers cut major setup time required to transition a Swing Axle TeleStacker Conveyor from transport to radial positions. The new Swing Axle XTP TeleStacker Conveyor shifts from road to ra��� dial mode in just five to 10 minutes. That is compared to 45 to 60 minutes for the origi��� nal model, a design still common to competi��� tive swing axle telescopic conveyors. Three key design features characterize the next generation Swing Axle XTP. n To engage the stacker���s power travel, chains and sprockets are replaced with a pre���installed t���handle mechanism. While the chain and sprocket arrangement takes up to 30 minutes to install, requires maintenance and can be tricky to guard, the new power travel system takes just seconds to engage and needs no mainte��� nance or guarding. n 46 there is no welding on the idler assembly, any damaged parts can be replaced in just minutes. Rollers can be refurbished at a fraction of the price of new ones, with 90 percent of the materials re���used. n The addition of a pivoting walking beam allows for true wheel alignment during radial travel. Poor alignment results in tire scuffing and can even cause a con��� veyor���s feed point to shift out of position. First generation Swing Axle models can be retrofitted with the new Swing Axle XTP. The company also builds models for highly portable applications, extreme capacities, highly mobile terminals and applications that require tracked travel capabilities. Superior Industries, www.superior��� The new axle design requires fewer link arms during both transport and opera��� tional modes. This modification again helps to reduce setup time.
