Where should plywood be placed with rescue-lift air bags?

Plywood should be placed between the rescue-lift air bag and the ground to create a stable and even surface. This is essential for distributing the load evenly across the surface of the air bag, which enhances its effectiveness and prevents it from easily sinking into softer ground or uneven surfaces. Using plywood minimizes the risk of the air bag rupturing or malfunctioning due to pressure points that could occur if it were placed directly on unstable or uneven terrain. This practice also helps in protecting the air bag from dirt, debris, and potential punctures on the ground surface, maximizing the safety and efficiency of the lift operation.
