Analysis and optimization of safety tools in load lifting for risk prevention and improvement of work efficiency, for contractor companies in mining.

Abstract

This research aimed to analyze the risks and safety protocols for lifting operations, especially in subcontracting chains. This article examines and proposes the optimization of an integrated and articulated package with formal lifting planning and Critical Controls management. A descriptive methodology with a deductive, non-experimental approach was used: review of standards and evidence 2015–2025; diagnostics in contractors through incident analysis, structured observations, and verification of competencies; and multicriteria prioritization of controls with assessment of risk-task couplings, followed by a pilot with independent verification. The results obtained were the product of the analysis of documents provided by the company and the results integrate technical criteria (ASME, EN, ISO, OSHA) and leading metrics to demonstrate barrier functioning in the field, as well as its link to efficiency (cycle times, retries, and rework). Collectively, a operating framework is proposed that reduces exposure to high-potential events and stabilizes performance, offering decision tables and a metrics dashboard for the mandating-governing contractors. It is concluded that effectiveness depends on the quality of planning (P30.1), verifiable competence (ISO 23814), disciplined use of tools (tag lines, safety hooks, load cells), and the calibration of technologies in controlled pilots, learning from quasi-losses, and data integration for continuous improvement. This contribution provides a roadmap for mining contractors seeking to prevent risks and improve their efficiency, aligning standards, competencies, and technology with verification at the point of work.
