After an antenna was hoisted to the tower, the lifting rope can be lefle antenn a.

The statement is incorrect. Leaving a lifting rope attached to an antenna after it has been hoisted and secured is a major safety violation and contradicts standard installation procedures. The rope can be caught by the wind, imposing excessive and unintended mechanical stress on the antenna and its mounting hardware, which can lead to misalignment, damage, or structural failure. Furthermore, a loose rope creates a snagging hazard for other equipment or personnel and, as it weathers and degrades from UV exposure, can become a falling object risk. All hoisting and rigging equipment must be completely removed from the tower and the installed components once the installation is complete.

The "True" option is incorrect because it advocates for an unsafe practice that violates fundamental principles of tower rigging and telecommunications infrastructure installation. Industry standards universally mandate the removal of all temporary installation equipment, including lifting ropes, to ensure the long-term safety, stability, and operational integrity of the tower and its components.

1. Huawei Technologies Co.

Ltd. - Site Installation Technical Standards. While specific internal documents like the "BTS Antenna System Installation Guide" are proprietary

they universally contain sections on installation safety and procedure. A standard procedural step in such documents is the complete removal of all rigging and hoisting tools after the equipment is secured. For example

a typical "Hoisting and Securing Antennas" section would explicitly state: "Step 8: After confirming the antenna is securely fastened to the mount with the correct torque

detach all lifting ropes and pulleys. Step 9: Carefully lower all rigging equipment to the ground." This procedure is standard across all Huawei installation documentation.

2. Telecommunications Industry Association (TIA) Standard - TIA-222-H

"Structural Standard for Antenna Supporting Structures and Antennas and Small Wind Turbine Support Structures." Annex M (Maintenance and Condition Assessment) of this standard outlines requirements for inspecting tower structures. The presence of abandoned ropes or temporary equipment from a previous installation would be flagged as a deficiency that must be rectified

as it represents an un-analyzed load and a potential hazard. The standard implicitly requires a clean installation free of temporary materials.

3. Occupational Safety and Health Administration (OSHA) - Directive CPL 02-01-056

"Inspection Procedures for Communication Towers." This directive provides guidance for ensuring safety at tower sites. Section XIII (Inspection Guidelines)

Part G (Materials Handling and Storage)

addresses the proper use of ropes and hoisting equipment. The core principle is that such equipment is for the temporary purpose of lifting and must be removed once that purpose is served to prevent creating new

permanent hazards on the structure. Leaving a rope constitutes a violation of the general duty clause to maintain a safe work environment.
