Which components of a tower crane are connected with high/tensile bolt connections?

The connection of various components in a tower crane using high/tensile bolt connections is crucial for ensuring the structural integrity and safety of the crane. High/tensile bolts are designed to withstand significant loads and stresses, making them ideal for critical joints where structural stability is paramount.

Foundation anchors are bolted to secure the crane to the ground, ensuring that the crane remains stable during operation. The tower sections are often joined together with high/tensile bolts to maintain the overall strength and rigidity of the tower structure as it reaches vertical heights. The slewing ring support, which allows the crane to rotate, requires robust connections to prevent any movement that could lead to a failure during operation. The strength provided by these bolt connections is vital as it ensures that the entire crane can function effectively under various load conditions and operating circumstances.

In contrast, the other options consist of components that do not typically utilize high/tensile bolt connections in the same way. For instance, the hoist drum and load block are more associated with dynamic load management and may involve different fastening methods, such as welding. Likewise, the electrical system and safety devices primarily involve wiring and circuitry rather than mechanically bolted connections, while components like outriggers, though important for stability, do not typically
