Why might blocking be placed under the ends of tracks?

Placing blocking under the ends of the tracks serves to increase the crane's stability, especially when operating over the front or back. This is particularly important in situations where the crane is extended to its limits, or when lifting heavy loads that could cause it to tip. By distributing the weight more evenly and enhancing the contact with the ground, the blocking helps reduce the risk of instability and tipping. It creates a larger footprint for the crane, which is crucial when operating on uneven terrain or when the load is positioned in such a way that it shifts the center of gravity.

This function is vital during operations that demand precision and safety, as any shift in weight or unevenness can lead to hazardous situations. Therefore, the use of blocking is a proactive measure to ensure that the crane remains secure and stable during various lifting operations, thus safeguarding both the equipment and the operators.
