POKA YOKE+ SYSTEM INTRODUCTION

Description

Poka Yoke+: functioning principle
The system is controlled by measuring the air pressure at the inlet side of the air motor. This air pressure varies from free running to impulsing. By this measured air pressure the controller detects contact of the bolt head (point 2).

Upon contact, the adjustable timer gives the shut-off signal (point 3). Adjustability of the timer takes care of adoption to either hard or soft joints. Similar, the controller detects double hits and trigger release before shut-off.

Poka Yoke+ System

IMPULSE WRENCHES
  • Complete freedom of movement by use of batteries
  • Very low weight / torque ratio
  • High speed fastening
  • Acoustic and LED signals for tightening status indication
  • No Kickback
  • Electric (brushless) servo drive, freely RPM adjustable
  • Hybrid technology
  • 100% check on tightening abnormalities like cross thread, double hit, etc.

Sizing Options

Superior clampforces
In conventional shut-off tools point 2 is the shut-off point. Due to the above mentioned principle of the Poka Yoke+ controller, the relaxation is minimized and the correct torque and clampforce are achieved. This system is more accurate than shut-off or standard impuls wrenches. The torque is adjusted at the impulse mechanism. In combination with the parameters in the controller YTC-3, a reliable shut-off is achieved.

 

The whole system is more accurate than shut-off or standard impulse wrenches.
