NORBAR Torque Tools Ltd has added a two-speed automatic gearbox and special nose extension to its Pneutorque pneumatic torque wrench.
The company claims it has achieved a major breakthrough n making the tool suitable for ise on high-volume production ines such as fork lift truck and ;ommercial vehicle assembly.
Norbar claims that tightening iuts accurately to a preletermined torque using the 'neutorque has always been a ;low process, especially on long breaded bolts, due to the low jeering necessary to produce he required torque load.
It has developed a new fully iutomatic gearbox that runs the lut down at up to 25 times iormal speed, senses a torque esistance, and automatically hanges into low gear to apply he final torque, so making the 'neutorque eminently suitable D r use on assembly lines.
The new nose extension fits in ilace of the standard reaction date and has overcome the roblem of tightening bolts in onfined spaces.
The unit comprises an outer the with forged reaction foot — -irough which passes a square rive mounted in bearings — nd is available in standard angths of 6ft, 9ft and 12ft irith either 3/4in or lin square rives.
The resulting extension is only mm at the drive end and pes easily with deeply cessed wheel nuts or bolts in ht corners.
