2 Day Program
Advanced Arboricultural Rigging
Designed for the experienced arborist, tree worker and groundworker, this 2-day program focuses on advanced rigging and force evaluation techniques and trees with elevated risk factors. Creating safe and efficient rigging plans that function in ‘real world’ scenarios and enhance worker safety make up the foundation of this program. Rigging practices covered in this program include lifts, balances, slide lines, guy lines, spar tree rigging, double blocking and load transfers. Building and calculating mechanical advantage will also be thoroughly covered to give workers the best possible chance at getting the job done safely and efficiently.
Topics Include:
• Worksite and tree hazard assessment
• Rigging equipment selection and inspection
• Safe Working load limits and factors of safety
• Creating or selecting appropriate anchor points
• Calculating and minimizing shock load
• Cutting selection, sequence and safe operator exit
• Friction management and lowering devices
• Forces, angles, and resultant vectors
• Using multiple anchor points for lifting, balancing, and lowering
• Tag lines and mechanical advantage
• Controlled slide lines and guying
• This program focuses on advanced rigging techniques. Some traditional rigging may not be extensively covered.
Recommended Prerequisites for this program include:
Introduction to Chainsaw Operation
