Grey-black, matte finish.
|Features and applications||
Particularly suitable when the lever turning angle is limited owing to lack of space and to avoid any accidental shocks which may affect the clamping action.
|Instructions of use||
For clamping push the lever to engage the clamping device toothing and turn it. By releasing the lever, the return spring automatically disengages the toothing and lever return to its rest position. <BR>In case of accidental shocks, the lever turns freely without affecting the clamping action enabling the operator to manoeuvre in safety.
Glass-fibre reinforced polyamide based (PA) technopolymer, with "PUSH" tampoprinted in red colour (avoid contact with solvents, alcohol or detergents containing alcohol).
Glass-fibre reinforced technopolymer clamping element, black colour, with knurling on the protruding part to make initial tightening easier. Black-oxide steel retaining screw, AISI 302 stainless steel return spring.<BR>Black-oxide steel threaded stud, chamfered flat end UNI 947 : ISO 4753 (see Technical Data).
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. ERS.p adjustable handle can withstand without yielding. <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.
