Pulse nutrunner Atlas Copco Applications Industrielles

The ErgoPulse principle
The heart of a pulse tool is the hydraulic pulse unit, positioned between the air motor and the outgoing shaft. Since the pulses are very short, there is almost no reaction force in thehandle, only the much lower motor torque is transferred to the operator’s hand. The pulse unit increases the torque generated by the motor 50-100 times. As there is no metal-to-metal impact in a pulse tool, pulse tools provide a softer, more controlled pulse with considerably less vibrations and noise than an impact wrench. Together with good balance and low weight the result is a tool that
is extremely comfortable to operate. The reliability and accuracy of the ErgoPulse
tools make them ideal for many situations.

A complete range
The ErgoPulse range covers torque from 2-900 Nm and are available in both shut-off and non shut-off versions. The shut-off pulse tools – PT, PTS and PTX
types – will shut-off the air supply as soon as the pre-set torque has been reached.
With a shut-off tool the operator influence is minimized. The result is increased accuracy and faster tightening. The non shut-off tools – C and XS types – produce
pulses until the operator releases the trigger. They are preferred in applications
where it is an advantage for the operator to be able to control the process
by shutting off the tool manually. Atlas Copco pulse tools are available
in straight and pistol grip versions.

Probably the most powerful pulse tool in the world
The newest addition to our PTX is the EP 25 PTX , which builds up torques between 450-900 Nm extremely fast and only weighs about 10 kilogram.
