mobilize in soft conditions. The HM400s replaced older Volvo models. Sidwell Materials runs about 12 rigid frame trucks and twice as many articulated trucks all Komatsus or Volvos. Our articulated trucks will do 100 to 120 passes a day. They are bought to do a job and we work them hard. Our operators have always liked the Komatsus including the excavators rigid frame trucks and artics. They like the comfort the ride and the power the machines offer Sidwell observed. Since operators have to sit in a machine for eight to ten hours a day you want to keep them happy so they can do a good job all day long. While Sidwell Materials is proud of its modern up-to-date fleet the company is a little leery of being a first adopter of Tier 4 technology. When possible such as when the company purchased its excavators it chose Tier 3 models. However Sidwell said buying from Columbus Equipment Company gave him confidence when he had to purchase Tier 4 models including his articulated trucks. Tier 4 is a huge step. There are lots of new things on the trucks that werent there two years ago. Its new to everyone all the manufacturers and it is inevitable there will be problems along the way as all the manu- facturers try to get the bugs out he said. I know that Dan Minnis and Columbus Equipment Company is the best at trouble shooting and fixing any problems that arise and getting our machines back into production quickly helping us to stay productive and keep our machines running. In fact a major reason behind all the purchases is the dependable service Columbus Equipment Company provides throughout Ohio. At some of the locations where we work it is hard to get dealers to respond to our maintenance needs and Columbus Equipment is very good at that Sidwell noted. While Sidwell Materials does in-house service for most of its rolling stock it contracts with Columbus Equipment to provide PM services for some of its Komatsu equipment. They help us keep track of PM services and they show up at 430 or 5 p.m. on Friday waiting for us to be done for the day. When we come in on Monday the maintenance is done and we know it has been done correctly Sidwell said. Sidwell finds another benefit to working with Komatsu machinery and Columbus Equipment Company is KOMTRAX Komatsus telematics system which enables technicians to diagnose a problem before seeing the machine. I am a big fan of 6 I know that Dan Minnis and Columbus Equipment Company is the best at trouble shooting and fixing any problems that arise and getting our machines back into production quickly.
