Loaders and excavators

Please consider to add loaders and excavators. They could be used for removing small hills before road planning, loading the dirt, grabbing scrap and loading sand when the dump truck tipps over. Maybe changable shovels and grabbers?

Some ideas:

Wheeled excavators, like EO 3322 (for the start)

Tracked excavators

Attachment for Kirovets/Kronenwerk

Some big and small wheel loaders, modern and old

tracked loaders

Swing loader like HATRA SL 125

excavator on trucks
