Rope-pull safety switch
Pizzato Elettrica
Pizzato Elettrica has designed and patented new accessories to install the rope of safety switches faster and to obtain an aesthetically more pleasant system.
The new accessories, in comparison with the traditional fixing system through carpentry material, have the following advantages:
* The installation is faster because only one screw is used for the fastening of every rope extremity, and the parts are prepared to ease the installation. Some practical tests have pointed out that the installation time is halved, reason for which it is named FAST.
* The system is aesthetically pleasant, because thread parts (which sometimes tear operators' dresses) and the rope extremities, usually fixed by heat-shrinkable sheath or adhesive tape, have been hidden.
* The red plastic covers of the fixing parts have been developed also for the function of controlling the rope clamping. If the rope fastening screw is not fixed tightly enough, the cover cannot pass.
* The rope is fixed without folds, thus reducing the rope stabilisation time and the possible re-calibrations of the rope tightening.
Furthermore two sturdy pulleys has been introduced in applications where the rope is very long in order to support the rope length or to bend its route. They are designed to avoid any deformation and to allow the rope to remain in its seat also when it is energetically activated.
