🌰 Orchard Hazelnuts: Ergonomics & Harvest Techniques
Safe operating procedures for orchard gathering, ground recovery, tool handling, and back strain mitigation.
1. Primary Physical Risk Factors
- Repetitive Stooping & Ground Gathering: Manual sweep recovery requires rapid, repeated waist bending.
- Vibration Stress: Handheld mechanical limb-shakers or backpack sweepers cause Hand-Arm Vibration Syndrome (HAVS).
- Neck Hyperextension: Looking up into tree canopies during mechanical shaking or manual pruning.
2. Biomechanical & Ergonomic Standards
Always utilize long-handled orchard rakes and rolling nut gatherers to keep the spine neutral. Mandate ISO-certified anti-vibration gloves when operating backpack sweepers or motorized equipment.
3. Step-by-Step Harvest Protocol
- Canopy Sweep & Clear: Clear drop zones around trunk bases using long rakes while maintaining an upright spine.
- Center-Out Gathering: Rake nuts into central windrows along tree rows rather than scattered piles.
- Two-Person Bin Lift: Bend knees to 90 degrees, keep totes flush against the body, and lift on joint count.
