Plant operators use heavy machinery to dig, lift and move materials on a building site. 

In charge of machines such as bulldozers and dumper trucks, mobile elevated work platforms, giant cranes, compactors and excavators (JCBs). 

Working outdoors and sometimes at height if using a tower crane or one of the larger excavators

With this type of role, you normally become an expert in one type of large machinery, and do everything from driving and operating the machinery to keeping it running properly
