The term 'construction machine' refers to two pieces of heavy machinery used in the construction industry: a loader (6 letters) and a CRANE (5 letters). A loader is a type of tractor with a large, front-mounted square bucket that is used for digging and loading materials. A CRANE is a tall, mobile machine with a long arm and a hoist that is used to lift and move heavy objects. Both machines are essential for the construction of buildings, bridges, and other large structures.
