To prevent forward movement when securing metal coils with eyes lengthwise, what should be utilized?

To effectively prevent forward movement when securing metal coils with eyes lengthwise, the use of both blocking and friction mats is essential. Blocking provides a physical barrier that helps to stabilize the coils by preventing them from shifting forward under the influence of acceleration or deceleration. This is crucial since metal coils can be heavy and their weight can cause significant movement if not secured properly.

Friction mats complement the blocking by increasing the friction between the coil and the surface they are resting on. This additional friction helps to hold the coils in place, further reducing the chances of them moving. The combination of both blocking and friction mats creates a more secure environment, mitigating the risk of cargo shifting during transit.

Using only one method, such as solely blocking or only friction mats, may not provide enough security. Blocking alone may not effectively prevent lateral movement, while friction mats on their own may not be sufficient to withstand the weight and force exerted by the coils without additional support. Therefore, employing both strategies together offers the best protection against any forward movement, ensuring a safer and more stable transport process.
