Big Kate is a dragline that has been running for over 50 years and is one of the last remaining of its size.
It has an operating weight of 10 million lb and a bucket that can hold up to 100 cubic yards of material.
Big Kate was originally designed to operate for 25 years but has far exceeded that lifespan.
The dragline was recently saved from being scrapped and is now up and running again.
Big Kate is a true engineering marvel and a testament to the durability of heavy machinery.
