swingbar nutrunners smaller faster lighter cleco proudly introduces the new 64 series swingbar nutrunners for high torque applications where a small tool is necessary for consistency in clamp load across joint types or for simply eliminating the maintenance needs of an angle tool the new 64 series tools provide the best solution for today s heavy assembly environment both prevailing torque and type of joint can limit the accuracy of a clutch or pulse tool on softer joints torque threshold is reached early in the fastening cycle resulting in long rundowns especially difficult on pulse tools on a long rundown a swingbar tool that is able to maintain a steady speed minimizes the time required to run down a fastener on a typical hard joint with prevailing torque a torque spike will occur which can prematurely shut off a clutch or pulse tool in tools with speed shifts a torque spike will also cause the speed to shift down resulting in a slower rundown the cleco 64 series swingbar nutrunners are not affected by torque spikes speed and torque tests for the new cleco 64 series swingbar nutrunners the goal of any fastening application is to maintain a high degree of accuracy while minimizing the length of time required to perform the rundown the new cleco 64 series swingbar nutrunners utilize a single powerful motor that limits speed shifts and offers a fast and accurate rundown regardless of joint type competitive units with high rpm s quickly drop their speed at threshold resulting in an overall longer rundown period this gap is multiplied when prevailing torque is present to read the graphs below the orange line represents the tool speed while the blue line represents the torque generated throughout a rundown notice the correlation between speed and torque and its overall effect on rundown time the swingbar can instantly be positioned to absorb the torque reaction of the tool while maintaining a comfortable position with the trigger hand benefits of a swingbar tool a swingbar tool includes a reaction bar that freely swings 360° this allows the reaction bar to be moved to an appropriate bracing point without any disassembly or repositioning of a spline once positioned the reaction bar absorbs the reaction forces of the tool reversible a simple to use and convenient slide reverse lever improves productivity by allowing for the loosening of fasteners without changing tools random comparison on 120° joint cleco torque ­ newton meters competitive twin motor torque ­ newton meters 1.6 sec 310 nm 1.7 sec 310 nm speed ­ rpm improved ergonomics top and bottom air inlets help customize the 64 series reaction bar nutrunners to the operator s work area ergonomics infinite-position reaction bar can quickly be moved to an appropriate brace point eliminating reaction forces of the rundown time ­ seconds speed ­ rpm time ­ seconds although the free speed of the cleco tool is slower tightening speed is faster which in this application results in almost equal overall times random comparison on 720° joint cleco torque ­ newton meters competitive twin motor torque ­ newton meters 4.2 sec 306 nm 6.0 sec 312 nm speed ­ rpm improved ergonomics comfort molded handles and lighter weights reduce operator fatigue and improve productivity time ­ seconds speed ­ rpm time ­ seconds again the free speed of the cleco tool is slower however with its faster tightening speed the overall time is almost 2 seconds faster 40 41
