D9T Sample is Here

We received the D9T hand samples from our manufacturer in Korea this week, and we have to say that the quality and attention-to-detail are excellent.


Features of this D9T include:  a positionable single-shank ripper, U blade with spill guard, individually-linked, free-rolling tracks, working track tensioners, fully-functioning bogeys, opening engine doors, a detailed operators cab with functional doors, lights, grab handles, and hydraulic lines.

During our review process, one issue that we noticed was that the edges of the gusset have a sharp, 90-degree angle.  The gussets on the real machine, however, have rounded edges.  As minor as this inconsistency may seem, it is an error that we are concerned with as we always aim for perfection, and it will be corrected before the production model is released.

Remember to keep an eye on this blog for more information regarding the D9T and other new products from Classic Construction Models.

10/26 – 10/28 – Measuring the 5230

Our introduction to Minnesota was a round of applause for the American Airlines pilot who finessed our plane onto the Minneapolis runway in 30 mph cross winds.  Four and a half hours later, after battling those same crosswinds, snow, sleet and rain, we went to bed early for our trip to the Arcelor Mittal mine on Wednesday morning.

After a quick breakfast we met our contacts from the mine and Caterpillar and made the short trip to the mine site.  Another 8 miles of driving within the mine took us to where the 5230 was located.  Our arrival time was set up to fall within the weekly, 8-hour down-time maintenance shift.    It took us about two hours to get all of the dimensions we needed to start developing our computer model, after which we tracked down the one 992C still working at this mine for a few more reference photos and dimensions.

A look around the mine was followed by a tour of the processing plant where the raw rock is transformed into iron pellets that are shipped by train and boat to another Arcelor Mittal factory to become steel.


Our hosts from the mine and Ziegler Caterpillar were both extraordinary in their assistance in getting us to the machines.  We’re all very excited about making the 5230 model and looking forward to the  possibility of a larger shovel down the road when CAT rolls out their new product lines!
