Which of the following is a common type of equipment used in construction?

Excavators are indeed a common type of equipment used in construction. Their primary function is to dig, move, and transport material, making them invaluable for tasks such as excavating foundations, trenches, and large earthmoving projects. Excavators come equipped with a variety of attachments that enhance their versatility, allowing them to perform various functions, including digging, lifting, and demolition.

While generators, paint sprayers, and gardening tractors are useful in their contexts, they do not serve as the primary heavy equipment typically associated with major construction projects. Generators provide power, often for temporary setups; paint sprayers are specialized for finishing and coating surfaces; and gardening tractors are typically intended for agricultural or landscaping tasks, rather than large-scale construction activities. Hence, excavators stand out as a quintessential piece of machinery within the construction industry, fulfilling essential roles in both residential and commercial building projects.
