What is an optimal tie-down angle for securing cargo?

An optimal tie-down angle for securing cargo is approximately 30 to 45 degrees from horizontal because this angle provides a balance between effective force application and stability. When tie-downs are positioned within this range, they create sufficient tension to secure the load without risking slippage or shifting during transport.

At angles less than 15 degrees, the tie-downs may not apply enough pressure to keep the load secure, leading to potential movement. On the other hand, angles approaching or exceeding 60 degrees could result in excessive tension, which might damage the cargo or the tie-down equipment itself. A vertical tie-down, while seemingly secure, can also lead to less effective load stabilization because it does not utilize the mechanical advantage provided by the angles. Therefore, the range of 30 to 45 degrees is considered optimal for achieving the necessary balance of security and safety in load securement practices.
