Tensioned Buttress System is a stabilization system consisting of which of the following?

• A. A stabilization system consisting of posts and braces placed around the vehicle
• B. A stabilization method using inflatable cushions
• C. A stabilization method using cables and guy wires
• D. Posts and struts wedged between the ground and the vehicle to prevent movement

Answer: (D)

The main idea is to create a rigid, non-movable anchor between the vehicle and the ground so the vehicle cannot shift during stabilization. A tensioned buttress system achieves this by driving posts into the ground and placing struts against the vehicle, then tightening or wedging them so they press firmly and distribute the load into the earth. This creates a stable, reciprocally braced structure that resists movement in multiple directions, which is essential during cutting or lifting operations.

This approach is distinct from inflatable cushions, which use air to support and can shift under load, and from cables or guy wires, which apply tension but don’t form the tight wedged interface between ground and vehicle that a buttress provides. It’s specifically about posts and struts wedged between the ground and the vehicle to prevent movement.
