Large machinery refers to heavy equipment designed for various industrial, construction, and agricultural tasks. Examples include excavators, bulldozers, and cranes, which are used to move earth, lift heavy materials, and perform other demanding operations. These machines are typically powered by diesel engines or electricity and are essential for increasing efficiency and productivity in large-scale projects. The operation of large machinery often requires specialized training and safety precautions due to their size and power. Operators must understand how to control these machines effectively to prevent accidents and ensure smooth operation. Regular maintenance is also crucial to keep the machinery in good working condition and extend its lifespan.
