What is a spider bob used for?

  1. Aligning the elevator car

  2. Inspecting safety systems

  3. Plumbing the hole

  4. Setting the control mechanisms

The correct answer is: Plumbing the hole

A spider bob is primarily used for plumbing the hole, which means ensuring that a vertical opening or shaft is correctly aligned. This tool provides a weighted line or plumb bob that is dropped into the hole, allowing workers to confirm that it is vertical. This is crucial in construction and maintenance work as it ensures that components such as elevators, pipes, or other structures are positioned accurately, preventing issues that could arise from misalignment. While certain tools might serve similar purposes in other contexts, the spider bob's specific design makes it particularly effective for this job. It essentially helps maintain precise vertical alignment, which is foundational in many mechanical and construction applications.
