| Ground-level Positioners | Hydraulic or manual jacks | Lifting rolls for positioning at the deployment point. |
Step-by-Step Handling Procedure
The following procedure outlines the best practices for handling heavy geomembrane rolls on construction sites:
Pre-handling Inspection: Inspect the roll for any existing damage. Check the packaging and the core for integrity. Document the roll number and condition.
Site Access Assessment: Ensure the access route is clear of obstacles, is level, and has adequate load-bearing capacity for the handling equipment.
Equipment Selection: Select the appropriate lifting equipment based on the roll weight, site conditions, and the distance to the deployment area.
Lifting from the Core: For heavy rolls, always lift from the core using a lifting beam. This prevents damage to the geomembrane surface.
Transport to Deployment Area: Move the roll slowly and steadily. Avoid sudden stops or turns. Use spotters to guide the operation.
Positioning for Deployment: Lower the roll onto the ground-level positioner or directly into the deployment cradle. Ensure the roll is stable and oriented correctly.
Post-handling Inspection: Inspect the roll again for any handling-related damage. Document any issues.
