Which safety measure should be taken when installing counterweights?

Following the manufacturer's guidelines is essential when installing counterweights because these guidelines are based on comprehensive safety testing and engineering principles relevant to the specific equipment being used. Manufacturers provide detailed instructions on the correct installation procedures, weight specifications, and the necessary safety precautions to ensure that the counterweights will function effectively without compromising safety.

Adhering to these guidelines ensures that the counterweights are installed correctly, taking into account factors such as load distribution, balance, and the specific machinery's design limitations. It reduces the risk of accidents that could arise from improper installation, such as tipping or equipment malfunction. Implementing these guidelines promotes a safer work environment and helps in maintaining the integrity of the rigging system.

The other options, although they carry their own importance, do not replace the significance of adhering to the manufacturer's guidelines in terms of ensuring the correct procedures and safety standards are followed during counterweight installation.
