Additional information

Colour

Grey-black, matte finish.

Features and applications

Particularly suitable when the lever turning angle is limited owing to lack of space. <BR>Compared to other types of adjustable handles with metal retaining screw this solution offers:<BR>- absolute electric insulation for the operator's hand<BR>- more comfortable lever release.

Instructions of use

For clamping, lift the lever to disengage the clamping device toothing and bring it back to start position. By releasing the lever, the return spring automatically engages the teeth.

Lever body

Glass-fibre reinforced polyamide based (PA) technopolymer. Resistant to solvents, oils, greases and other chemical agents.

Other executions on request

Lever body in orange (C2) with black push button (C1).<BR>Example: code 235071-C2-C1 description ERX.30-SST-C2-M5-C1.

Push button

Technopolymer in Ergostyle colours, glossy finish.

Standard execution

Glass-fibre reinforced technopolymer clamping element with retaining pin, black colour, with knurling on the protruding part to make initial tightening easier. AISI 302 stainless steel return spring.<BR>AISI 303 stainless steel boss, threaded blind hole.

Stress resistance

<P>Adjustable handles are generally used for repetitive clamping operations sometimes with very high-frequency. <BR>Therefore, the stress resistance (i.e. the resistance to repeated tightening cycles) of the handle unit is particularly important and, especially, the strength of the toothed element which transmits the tightening force from the handle to the threaded element (boss or stud). <BR>In fact, the results of several laboratory tests, perfomed with a special instrument that simulates the most severe use conditions, have shown that e.g. ERX.78 SST adjustable handle can withstand without yielding more than 100,000 tightening cycles, under the action of a force of 490 N (see graphic). <BR>The special glass-fibre reinforced technopolymer enables the ELESA adjustable handles to guarantee stress resistance values which are much higher than the ones generated under normal working conditions.</P>
