Yokota YZ-NP Battery Impulse Wrench

Yokota system e-wrenches have a built-in torque transducer and angle-encoder on the main shaft and is wireless connected to a controller. The Yokota battery system e-wrench is the perfect solution for applications where cables or hoses are disruptive, but you still need to have all data checked, controlled and documented. Wireless communication with the control unit WU-1 for up to 10 meters. Each controller can be paired with up to 4 independently operating battery system e-wrenches. For data-collection, the controller is equipped with a RJ-45 connector for LAN Ethernet TCP/IP. Optional Display DC-2 shows tightening result (OK / NG and torque level reached) and either the free running angle, the tightening angle or the number of bolts and number of impulses. Connection to the WU-1 controller by means of cable with 5 meter length (included in delivery). [...]

The Yokota YZ-T cordless impulse wrench is detecting the amplitude of the tightening force from motor loaded condition. Based on the programmed values, the YZ-T wrench makes self-shut-off intelligently. As a result, the YZ-T achieves highest torque accuracy and safety against misconnections. An integrated status LED is visible virtually all around. The YZ-T series provides a rugged impact-resistant housing. Its pulse cell works without a mechanical shut-off mechanism and is easy to maintain. The optimized design allows extended maintenance intervals. The grip fits well in the hand and the tool is perfectly balanced. Intelligent Shut-Off. The combination of the adjustment of the pressure relief valve and the speed setting of the motor allows an optimal adaptation to the respective bolt joint to be connected. Thus the electronically controlled shut-off effects precisely and stable according to the entered parameters for smallest torque tolerances. [...]

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. [...
