Yokota YLTX Pneumatic Shut-Off Impulse Wrench

Hi-Tech Impulse Tool with Double Chamber Air Motor. The lightweight Yokota YLa series impulse wrenches with double chamber air motor achieve the required torque very quickly. The tools have a high number of impulses per second, and therefore very accurate torques can be realised, resulting in increased production speed. Design innovation and the application of new materials significantly reduce the weight and increase the service intervals. Yokota impulse wrenches are widely used for tightening jobs in the assembly industry, where accurate torque tolerances are necessary. Impulse tools are light, powerful, small and very importantly, have no kick-back. Evaluation of tightening processes in car assembly shows that tightening joints uses 10% of the total assembly time. Working with faster tools therefore can speed up assembly lines substantially. [...]

Electric Impulse Tool with Torque Control and Angle Monitoring. The YOKOTA electric system wrenches with integrated torque transducer and angle sensor offer a large reduction of energy consumption, a high degree of accuracy and fantastic work efficiency. Faulty tightening detection with maximum accuracy due to the use of an integrated torque transducer and also an integrated angle sensor. Torque transducer and angle sensor located directly at the front of the main shaft, giving the best accuracy of measurement. The angle sensor is an extremely compact (PAT) rotary encoder that detects both angle as well as direction by 1 degree, signal transmission contactless. Due to the newly developed outer rotor servo motor and the composite body, the Yokota system e-wrench has the lightest weight in its class. For cooling of the motor it is equipped with a fan that reduces motor size (and weight at the same time). For cooling of the impulse unit it is equipped with a separate fan. [...

YZ-NP impulse wrench is light weight, well balanced, and has a brushless DC motor. It allows 4 rpm settings (2000/3000/4000/4800) to be set according to application/joint conditions. No planet gear between motor and impulse unit resulting in extremely low vibration and low noise. Available Li-ion battery 18 V / 2.0 Ah provides LED capacity indicator and no memory-effect. LED indication appears on overheat error, motor/driver error, and low battery capacity. Pulse-Check Function: By teaching the tool the impulse cycle as a reference point, the YZ-NP is able to give a warning message for upcoming maintenance needs. Applying reaction-free Yokota impulse wrenches at the assembly line reduces the RSI risk significantly. [...]

Hybrid Technology – Smart Assembly Solutions The YOKOTA electric system wrenches with integrated torque transducer and angle sensor offer a large reduction of energy consumption, a high degree of accuracy and fantastic work efficiency. Torque transducer and angle sensor located directly at the front of the main shaft, giving the best accuracy of measurement. Faulty tightening detection with maximum accuracy due to the use of an integrated torque transducer and also an integrated angle sensor. During the tightening process, four different variables are measured and monitored: Torque - Angle - Time - Nº. of Impulses. Torque transducer measures directly and transmits the signals contactless. Detects cross threads, double hits, contamination, etc. Special feature to prevent cross threaded tightening: reversely rotating a bolt to a preset angle at the start of tightening. Combinations of buzzers and LED (Green / Red) for operator feedback on OK / NOK tightenings. [...]
