Columbus Equipment Company offers an extensive inventory of late-model used equipment from a large variety of manufacturers including Komatsu. Check out our current offering of used equipment. If you have any questions or need any additional information on a specific piece of equipment, please contact Jon St. Julian at (614) 332-3528.

Komatsu ReMarketing allows you to invest in high quality used equipment without spending a fortune. Unlike used equipment brokers and dealers who sell their equipment "as is" most Komatsu used equipment is distributor certified. That means Columbus Equipment Company performs testing, diagnostics, and minor repairs before we give it our stamp of approval. We even offer financing options and maintenance programs to make buying this high-quality used equipment that much easier.

You can't get any closer to the customer!

From the beginning, customer proximity has been at the top of our priority list. To this day, we are keen to be very close to our customers and their daily problems. With increasing order volume, we have therefore built up a dense network of our own branches around our headquarters in Münster-Hiltrup over the years. From our now four locations in Münster-Hiltrup, Leer, Nordhorn and Osnabrück, the managing director Peter Weeke looks after our customers with over 70 long-standing and competent employees and offer you a full service for everything related to construction. Our own modern fleet of vehicles from the Sprinter to the 32-tonner, a flexible field service with permanent contacts, competent office staff and a telephone exchange that answers questions and concerns directly, ensure that we are always there when you need us. In-house fitters, workshops and a mobile maintenance and repair service are just as much a matter of course for us as the express delivery, if it should go even faster. Because we know that speed and flexibility are the most important building blocks. The construction industry is our passion and we are happy to be able to support you in your construction project!
