Why would the guides need adjustment during the jacking process?

The necessity of adjusting the guides during the jacking process primarily relates to ensuring free movement of the climbing frame over the tower sections. As the jacking process involves the vertical movement of components, the alignment and spacing of the guides allow for smooth operation without obstruction. This adjustment is critical because any misalignment could lead to increased friction, potential damage to the climbing frame, or hindered movement, which could ultimately disrupt the jacking operation.

While aesthetic alignment and safety factors are important considerations in rigging and lifting, they do not directly impact the technical execution of the jacking operation as the functionality of movement does. Similarly, while temperature changes can indeed affect materials and could necessitate adjustments in certain contexts, they are not the primary reason for guide adjustment during the jacking process. Thus, ensuring the climbing frame can move freely is the most relevant reason for making guide adjustments in this scenario.
