Universal Power Wrench

ROBEL's Kupplungs-System (RKS - ROBEL clutch system) features an electrically operated and electronically monitored multi-disc clutch.

At identical outer dimensions, the discs provide nine times as much active clutch surface as in a cone clutch system, for example. Positive effects are noticeable in the torques transmitted and in the accuracy of engaging the clutch:

• exact torque transmission
• enhanced wrenching accuracy
• reduced wear
• improved stability
• low servicing needs

The central panel comprises

• an electronic torque indicator and
• torques preselected by a rotary potentiometer knob.

1. Use the rotary knob to preselect the torque – you don't even need to take off your work gloves,
2. place the flexible screw head on the fixing material to be tightened and
3. start wrenching by pressing the thumb push-button on the right handle.

At a spindle speed of 200 rpm, adjustable torques range from 150 to 350 Nm and up to 999 Nm at 70 rpm.

As soon as the preset torque value is reached, the display lights up and the wrenching process is automatically stopped.

• The torque reliably equals the selected value which is obtained almost without operator involvement.
• Moreover, the time the clutch is engaged is automatically minimised,
• which has a positive effect on the run and wear of the machine.

The digital LED display

• can be read well at any time
• is extremely sturdy
• is waterproof and installed in a way that inhibits vibrations

The equipment also features an electronic operating hour counter; enter the correct code to see

• the operating hours worked so far,
• the number of motor starts,
• the loosening and tightening cycles.
