Marcus Mumbach, of German website Bauforum24, "Das Portal fur Bau und Baumaschinen," ("Bau" means construction β€” you can probably figure out the rest), has helped complete the site's first Heavy Equipment Calendar for 2010. It's pure machine porn.

The calendar replaces traditional pin-up girls with 284-ton Terex O&K RH 120-E Mining Exvacators equipped with sets of honkin' 18-liter Cat engines, an even bigger 525-ton O&K RH 200 Excavator and a hot little 8.5-ton Kaiser SX Walking Excavator dressed in a skimpy blue number. All the shots are gorgeous. Take a gander through the months of the calendar at the link below. [ via core77 via carchat, Gizmodo]
