Why is it important to avoid overloading a lifting device?

Overloading a lifting device is critical to avoid because it compromises not only the integrity of the equipment but also the safety of those working nearby. When a lifting device is overloaded, it can exceed its designed capacity, which may lead to catastrophic failures. This could result in dropped loads, equipment malfunction, or even structural collapse, each of which poses significant risks to the safety of technicians and others in the vicinity. Such incidents can cause severe injuries or fatalities, underscoring the necessity of adhering to load limits to ensure safety in operations.

In contrast, the other options do not accurately reflect the real dangers associated with overloading. Slower operation speeds, the belief that modern devices can withstand overloading, or only minor malfunctions diminish the seriousness of the consequences and misrepresent the critical nature of equipment capacity and safety standards in the telecommunications industry.
