Features

Controller for managing the number of fastenings (quantity management)

“Management of number of fastenings” using air pressure sensor, “Automatic stop of wrench”, and “Display and alarm output” in case of abnormal fastening

The sensor detects the fluctuation of intake air pressure when the tool is in use, and judges the tightening based on the tightening time and number of strikes. It judges the tightening condition as OK/NG and counts the number of tightenings.

Connectable tools:
・Special wrench with pressure detection tube
・General-purpose impulse wrench ^*1

Features

For tightening bolts and nuts in tight spaces

Ratchet wrenches are small and lightweight, making it easy to work in tight spaces. When a certain torque is reached, the wrench stops rotating, preventing over-tightening or damage to the screw. You can also tighten the wrench by hand to obtain a higher torque (RW-120 only).

It is highly effective in streamlining and reducing the labor required for screw tightening in automobiles, aircraft, and other tight spaces, or in places where over-tightening is not permitted.

A fastening tool with low noise, low vibration and low reaction force

Basic model of impulse wrench

What is an impulse wrench (oil pulse wrench)?

Compared to impact wrenches, which utilize the striking force of metal, a hydraulic chamber (liner case) is placed between the motor and shaft, and the oil inside is suddenly compressed, and the pressure is transmitted to the shaft to generate rotational torque, significantly reducing the noise and vibration generated by the tool.

Fastening torque (generated torque) adjustment Hydraulic pressure adjustment function

The generated torque can be adjusted by opening and closing the relief valve (adjustment bolt) inside the liner case.

Lighter, quieter and smarter tightening than Yokota’s New Battery Series .

The ultimate tightening sensation. Smooth, gentle and careful tightening.

Shut-off mechanism

New mechanism
The motor’s load condition detects the magnitude of the fastening force and automatically stops it electrically.
Over- and under-tightening can be prevented.

Quality Level Up

High-precision fastening is possible by adjusting the target value, number of strokes, motor speed, and impulse unit.

Fastening result confirmation function

Simple setting function. By connecting PC-1, you can check the last 5 fastening data. It is easy to check the past fastening state and input the setting value.

Lightweight and compact

The short overall length of the tool makes it easy to set on the workpiece even in tight spaces. The
lighter weight reduces the burden on the worker of holding the tool, and the
more compact design improves flexibility and workability.
