Nutrunners with Swivel Arm

Figure Nutrunner with Swivel Arm Series 64

Smaller, Faster, Lighter

Cleco introduces: the new Series 64 nutrunners with swivel arm – for applications in the higher torque range where a small tool is required, as well as for consistent clamping force with different fastening conditions, or simply to reduce maintenance requirements for angle nutrunners. The new Series 64 delivers the best solution for today's demanding assembly environments.

Advantages of a Tool with Swivel Arm

Tools with a swivel arm have a reaction arm with a 360° range of motion. This allows the reaction arm to be brought into the required holding position without disassembly or repositioning of an additional wedge. Once attached, the reaction arm absorbs the reaction forces of the tool.

Both the rundown torque and the joint condition itself can impair the working accuracy of a clutch or an impulse tool. In softer joints, the threshold torque is reached earlier in the fastening cycle, leading to longer rundown times. This proves to be particularly difficult with impulse tools.

With long rundown times, a tool with a swivel arm can stabilize the speed and thus reduce the overall rundown time.

In a typical hard joint with rundown torque, a short-term torque peak occurs which can cause a clutch or an impulse tool to shut off prematurely. With tools featuring speed switching, the speed is also downshifted during such torque peaks and the rundown process is slowed down. Cleco Series 64 nutrunners with swivel arm are not affected by torque peaks.

Speed and Torque Tests for the New Cleco Series 64 Nutrunners with Swivel Arm

The goal of every fastening application is to maintain accuracy while simultaneously shortening the rundown time. The new Cleco nutrunners with swivel arm have a powerful motor that reduces speed fluctuations and ensures fast and accurate fastening, regardless of the joint condition.

Comparable high-speed products reduce the speed upon reaching the threshold torque, which leads to overall longer rundown times. This weakness is further amplified when a specific rundown torque is required.
