Additional information

Assembly

– Execution <strong>A</strong>: black-oxide steel boss, plain or tapped blind hole. Black-oxide steel retaining screw, AISI 302 stainless steel return spring.<BR>- Execution <strong>B</strong>: brass boss, tapped blind hole. Brass retaining screw, AISI 302 stainless steel return spring.

Clamping element

Glass-fibre reinforced technopolymer, black colour, with knurling on the protruding part to make initial tightening easier.

Colour

Black, orange, grey, matte finish.<BR>For sufficient quantities RAL 6011 green.

Features and applications

Particularly suitable when the lever turning angle is limited owing to lack of space.<BR>MR. adjustable handles can be quickly screwed during assembly by means of electric or pneumatic screwdrivers with controlled tightening torque system.

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 toothing.<BR>If the lever cannot make a 360° rotation, the clamping element can be easily screwed by means of the hexagon socket front head screw (after having disengaged the lever).

Lever body

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

Stress resistance

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. MR.80 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.
