1. DESCRIPTION OF LOAD LIMITER HF 31/1/A2

1.1. Area of application

This load limiter is specially designed to manage one or two safety thresholds on small and medium
capacity overhead travelling cranes.

1.2. Operating principle

Deflection of the wire rope exerted by the load limiter produces a tangential force which is proportional
to the force exerted on the wire rope when pulled.
Deformation of the load limiter body causes the micro switches integrated in the load limiter to open.

1.3. Technical specifications

Installation : directly on idle strand.
Repeatability : 1 % EM.
Measurement
sensor : 2 integrated micro
switches.
Contact 1 : 1 NO, 1 NC.
Contact 2 : 1 NO, 1 NC.
Cut-out voltage : 230 VAC max.
Cut-out intensity : 4 amps max.
Connection : electrical cable,
7 conductors.
Factory calibration option: for each threshold, indicate wire rope diameter + force on strand.
