A tower crane plumb tool
By designing a tower crane verticality measuring tool that includes a main scale, a measuring sleeve, and an angle measuring disc, the problems of multiple-person operation and complex processes in existing technologies have been solved. This tool enables a single person to quickly read the tower crane tilt angle data, improving inspection efficiency and reducing safety risks.

AI Technical Summary
Existing methods for measuring the verticality of tower cranes require multiple operators, involve complex processes, cannot flexibly adapt to standard sections of different sizes, and cannot directly read tilt angle data, resulting in low detection efficiency and high safety risks.
A tower crane verticality measuring tool was designed, comprising a main scale, a sleeve scale, and an angle measuring dial. The sleeve scale is nested inside the main scale, and it is equipped with a level bubble and an electronic/mechanical angle measuring dial, which are fixed by snap rings. This allows a single person to quickly read the tilt angle data, simplifying the measurement process.
It enables a single person to quickly and intuitively obtain the verticality deviation of the tower crane, reducing the risk of high-altitude operations, improving detection efficiency, and simplifying the operation process.
