Which of the following is a wood box-cribbing configuration?

• A. Crosstie platform
• B. Hydraulic jack spreader
• C. Dash lift technique
• D. Debriefing

Answer: (A)

Wood cribbing used for stabilization aims to create a solid, load-distributing platform. A box-cribbing configuration specifically means building a rectangular, box-like support by stacking cribbing blocks and interlocking cross-ties to form a stable framework. The Crosstie platform uses wood cribbing laid in crosswise (crosstie) fashion to construct a compact, four-sided structure with a flat top surface that spreads the vehicle’s weight across multiple supports. This distribution reduces crush risk at any single point and provides a reliable working surface for stabilization.

Other options involve tools or procedures rather than forming a wooden box-like support. A hydraulic jack spreader is a metal tool used to create space, not a wood cribbing box. A dash lift technique describes a lifting method, not cribbing. Debriefing is a post-incident discussion, not a stabilization configuration.
