What is a “Sack Law”??
Posted at March 05, 2025
A customer from Northern Chile contacted CPS to discuss options for their load and return conveyor rollers on their sacrificial belt. Chilean regulations aim to improve ergonomics for maintenance personnel and the site was also looking to extend the life of the rollers.
Ley del Saco 20949 ‘Sack Law’
CPS’ lightweight alternatives to steel rollers are especially appropriate in Chile where, over the past decade, the Chilean government has been gradually improving health & safety legislation to make working conditions better for all who work in Chile. One of these laws, the “Ley del Saco 20949”, roughly translated as “Sack Law 20949”, reduced the recommended maximum lift weight for an individual from 50kg down to 25kg for men and 20kg for women and people under 18 years of age.
CPS Solution
CPS Engineers performed comprehensive calculations on loads, stresses, weight, speed and other relevant factors, providing a complete solution.
Steel load rollers were replaced with Yeloroll-HD premium composite rollers. Each of the composite rollers had a unit weight of 24 kg, complying with the “Sack Law”.
For the return rollers, the proposal involved the installation of Yeloroll-HD rollers. There were some concerns around the 1.6 meter shell length, but CPS calculations confirmed the correct resistance for safe use on a 108” wide belt in a V-return application.
