Breaking loads and safe working loads
Breaking loads (BRL)
Our definition of a breaking load is that load which causes any part of a product to break when it is subjected to successively increasing loads during laboratory testing.
Safe working loads (SWL)
Our definition of safe working load is set at half the breaking load. We guarantee that products subjected to loads that are below or up to this limit will function satisfactorily.
Loads in the specification tables
The breaking load and safe working load values shown in the product tables are for the product itself (not for the line). The load exerted on the product depends on the load in the line and on the deflection angle of the lines around the sheave.
