Yokota e-M Electric EC System 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. [...]

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. [...]
