Zorluk: OrtaCargo Securement: Blocking and Bracing

When securing freight with a high center of gravity inside an enclosed trailer, installing wooden blocking directly against the base of the cargo on the deck floor is sufficient by itself to prevent the load from tipping over during transit.

Cevap: Cevap

Cevap

False. Base blocking on the floor prevents sliding along the deck, but bracing or tiedowns are required to prevent top-heavy freight from tipping over.
Floor-level blocking is mechanically designed to resist horizontal movement (sliding along the trailer deck). It does not provide leverage or structural support against the overturning moments experienced by tall, top-heavy cargo during sharp turns or heavy braking. To prevent tipping, drivers must use bracing anchored to the upper portions of the freight or appropriate tiedowns.

Adım Adım Çözüm

1
Identify the primary mechanical function of cargo blocking.
Blocking is placed on the vehicle floor directly against the cargo base to prevent horizontal sliding (front-to-back and side-to-side).
CDL regulations and physics define blocking as floor-level securement against sliding forces.
2
Evaluate the directional forces acting on cargo with a high center of gravity during transit.
Centrifugal and braking forces act on the upper mass of tall cargo, creating a rotational overturning moment around the base pivot point.
Floor blocking acts only at the deck level and provides no counteracting leverage against tipping forces acting on the upper center of mass.
3
Determine the required securement method to prevent tipping.
Bracing extending from the upper part of the freight to structural vehicle members (or direct angled tiedowns) is required to stop tipping.
Blocking alone cannot stabilize top-heavy freight against rotational failure.
