Practical Rigging and Lifting: A Guide to Load Calculations, Sling Selection, Safe Hoisting for Riggers Millwrights

Practical Rigging and Lifting brings together the calculations, equipment knowledge, and planning principles needed to understand industrial lifting operations. Written for riggers, millwrights, apprentices, and maintenance personnel, it explains how load behavior, rigging arrangements, equipment limitations, and site conditions affect lifting decisions.Clear explanations, illustrated equipment discussions, and step-by-step worked examples guide you from basic measurement to complete lifting scenarios.Inside the book: - Practical mathematics and measurement. Review unit conversions, geometry, trigonometry, and the distinction between mass and force.- Load weight and center of gravity. Calculate component weights, locate balance points, and determine support reactions.- Sling forces and load sharing. Examine sling angles, unequal loading, headroom, and the assumptions behind tension calculations.- Sling selection and protection. Study wire rope, alloy chain, web slings, and roundslings, including identification, configuration, contact hazards, and service limitations.- Hardware and lifting equipment. Explore shackles, hooks, lifting points, hoists, blocks, reeving systems, lifting beams, and spreaders.- Hitch selection and load stability. Compare lifting arrangements and assess load movement, restraint, and changes in support.- Machinery moves. Work through jacking, rolling, cribbing, bearing pressure, and staged load transfers.- Lift planning and inspection. Examine site assessment, crew responsibilities, communication, equipment disposition, and maintenance records.- Integrated worked scenarios. Follow the reasoning that connects calculations, equipment selection, inspection, and planning.Whether you are beginning an apprenticeship or strengthening your technical knowledge, Practical Rigging and Lifting provides a structured resource for understanding lifting systems and evaluating the decisions behind them.
