Features and applications

Solid handwheels GN 923.7 with safety fold-away handle are distinguished by modern design. <BR>These handwheels are suitable for applications where the handle must not remain in the operation position.<BR>In order to bring the handle into this position it has to be turned first through 90° to a stop against a torsion spring and then it is pushed against spring pressure into its hold position. By maintaining the forward thrust on the handle the handwheel can easily be rotated.<BR>When releasing the handle the springs returns it back to the retracted position.

Fold-away handle

Type GN 798.7 in polyamide based (PA) technopolymer, black colour, matte finish. Resistant to solvents, oils, greases and other chemical agents. The two-volume special design of the handle provides the operator's hand with a safe and ergonomic grip when turning the handwheel.
