Lowbed: A lowbed, also known as a lowboy, is a trailer that is specifically designed to transport heavy equipment such as bulldozers, excavators, and cranes. Lowbed trailers have a low ground clearance and are typically used for hauling oversized or overweight loads that cannot be transported on a standard trailer.
Excavator: An excavator, also known as a digger, is a heavy construction machine used to dig or move large objects. It typically consists of a cab, boom, dipper, and bucket. Excavators are commonly used for digging trenches, foundations, and holes, as well as for demolition work.
