About


This pulley with electromechanical overload detection is a simple and robust device for many winch applications in all fields (construction, industry...).

• - Easy installation
• - Outdoor use – 10°C / +50°C.
• - Electromechanical operation. Acts as a simple switch. IP67 contact.
• - Setting range: 110 to 125 % of nominal load.
• - Factory calibration.
Use:
• - The pulley can detect an overload in the wire rope thanks to a contact sensor (6 mm stroke).
• - Bellow the nominal force, the pulley is held by one (or more) prestressed spring(s). Above this force, the pulley moves compressing the spring and contacting the sensor.
• - The initial setting of the spring and the triggering force are set at the factory.
• - The detection occurs between 110 and 125% of the nominal load.
• - The trigerring depends on the effort between the two falls (one of which being always in line with the spring).
• - If this angle is 90°, the triggering force is compared to the force in one fall.
• - If this angle is 180°, the triggering force is compared to the force in two falls.
• - Acceptable assembly for 90 ° = from 85° to 95°, for 180 ° = from 160° to 200 °. These wire ropes angles must be respected in order to have an accuracy greater than 95 %.
