When step chocks are unavailable, which stabilization is recommended?

• A. Box cribs of correct height
• B. One rescue lift airbag located on each side
• C. Cribbing in front and back of wheels
• D. Wedges

Answer: (A)

When stabilizing a vehicle or apparatus in the field, the goal is to create a solid, level base that resists movement in all directions. Box cribbing of the correct height provides a rigid, multi-piece support that fits snugly under the wheel or contact point. It distributes the load across a wide, stable surface and can be stacked to reach the exact height needed to level the equipment. This makes it a reliable substitute for step chocks, minimizing the chance of slipping, sinking, or shifting and giving you a dependable, non-yielding foundation. Airbags are designed for lifting and can shift under load, especially on uneven ground, and require constant monitoring. Wedges offer limited stability and can slip or roll, providing less control than a full box crib. Placing cribbing only in front and back of the wheels may help a bit but doesn’t give the same comprehensive stabilization as a proper box crib built to the correct height. So, when step chocks aren’t available, using box cribbing of the correct height creates the safest, most reliable stabilization.
