Multiple Choice

Which stabilization method uses posts and struts wedged between the ground and the vehicle to prevent movement?

The main idea here is creating a strong, wedge-like restraint that locks the vehicle in place by bracing it against the ground. In a tensioned buttress system, posts are driven into the ground on opposite sides of the vehicle, and struts are placed between those posts and the vehicle. When the struts are tensioned, they push the posts firmly into the earth and press against the vehicle, forming a buttress that resists movement in any direction. This multi-point, tensioned brace distributes load across several contact points and maintains a tight, secure hold as lifting or other operations are performed. It’s especially useful on uneven ground or when you need reliable resistance to shifting, which makes it more robust than methods that rely solely on cribbing or edge contact without the same wedged, tensioned restraint.
