Machine safety components from Elesa – hinges, handles and handwheels
In other situations the Elesa EBR-CH bridge pull handle with integral lock offers a simple way of latching sliding doors with key lock without the need for installation of separate lock and grab handle – another simple, reliable and elegant solution as we have come to expect from this premium manufacturer.
A long recognized area of safety concern is that of shaft mounted revolving handwheels for machines. In this case the Elesa solid handwheel VD.FP+I+ST provides the assurance of a free spinning de-clutched mechanism until the operator pulls the handwheel to engage drive. Safety handwheels are designed in accordance with accident prevention rules: in case of push or accidental pressure when the machine is operating, the handwheel is disengaged and is in the rest position. Only by "Pulling" the handwheel parallel to the axis can the shaft operate: the two toothed elements inside the bushing fit into each other in order to couple the handwheel to the shaft. The handwheel returns automatically to its rest position when it is released after the operation.
These handwheels can be supplied with "Push-coupling". By inserting the bushing the other way round, the handwheel operates opposite to the standard way.
