Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for tower crane installation, and in particular to an auxiliary tool for installing a tower crane attachment frame. Background Technology

[0002] When tower cranes are used for anchoring operations, their working height is at least 18 meters, which is considered high-altitude work. During the on-site anchoring operation and installation of the anchoring frame, the left half of the anchoring frame is usually initially fixed to the standard section with wire. At this time, the installation level of this half of the anchoring frame cannot be guaranteed. When the right half of the anchoring frame is hoisted to this position, the length of the suspension wire of the left half of the anchoring frame needs to be continuously adjusted to achieve the installation matching of the two anchoring frames.

[0003] Because the work site is located at a high altitude and there may not be an operating platform available for the attachment installation, adjusting the level of the attachment frame is time-consuming and laborious for the installers and dismantlers. Sometimes, to improve efficiency, workers may resort to methods that violate operating procedures. Furthermore, to facilitate adjustments, the left half of the attachment frame is typically suspended by a single strand of wire during on-site construction, which poses a certain safety hazard.
