Resources required
- Learning Outcomes
- 1. Demonstrate knowledge or installation equipment, cable, hardware, and support materials in an arboriculture situation.
2. Describe the process of installing a cable support system and its application in arboriculture.
3. Describe the use and placement of rod bracing and propping systems in arboriculture.
4. Describe inspection and maintenance cycles required for tree support systems. - Content
- • Hardware and support materials; threaded rod, cable pullers, wire rope grips, swages, drill bits, thimbles, washers, ground anchor, tree props
• Cable types; 6 x 19 IWRC wire rope, Cobra,, Tree Save
• Cable Anchors; Lag hooks, (J-Screws), eye nuts, eye bolts, anti-friction hose (Cobra), webbing sling (Tree Save)
• Tree types as good candidates for accepting support; tree species, growth rate, age, condition, importance, type, area of weakness, amount and location of sound wood
• Branch suitability; size, attachment points, angle of cable
• Pre-installation pruning; branch end reduction, thinning
• Cable placement determination; distances, number of cables, proximity
• Support system effects; loading of trunks and stems, formation of reaction wood, reduction of natural movement, tightness of cable.
• Rod bracing systems; through bracing, dead-end bracing, distance below/above the crotch, distance between rods, multi stemmed trees
• Inspection and maintenance cycles; synthetic, non-synthetic, dynamic, rigid, growth rates, location of system. - Teaching and Learning Strategy
