What is the purpose of outrigger pads and cribbing?

• A. To distribute load, prevent sinking into soft ground, and provide a solid contact surface for stability.
• B. To add decorative touch to the setup
• C. To cool the hydraulic fluid
• D. To increase reach

Answer: (A)

Outrigger pads and cribbing exist to keep the aerial setup stable by spreading and supporting the weight over a solid, level surface. When the outriggers extend, the vehicle’s weight is pressed onto a small contact area. Soft ground, mud, or uneven terrain can let the pad sink or the leg tilt, which jeopardizes stability. Pads increase the contact area to lower ground pressure and prevent sinking, while cribbing provides a rigid, level base on soft or irregular ground so the stabilizers sit evenly and resist shifting. This directly enhances tipping resistance and safety during operations. The decorative option, cooling hydraulic fluid, or increasing reach don’t address stability, so they aren’t relevant.
