Our Philosophy

Our Philosophy

Our philosophy at Junjin America LLC is always focused on providing our customers a simple, low cost drilling solution. With this in mind we introduced the JD1400E Rock Commander and then followed up with the JD800ENC Rock Commander. These two models fill the needs of the majority of rock drilling professionals.

When looking for a new drill there are generally three things that a drill customer needs to consider. These are reliability, price and parts availability. When considering reliability, it should be noted that the Rock Commander utilizes proven components including the Yamamoto Drifters, Cummins Engines, Bosh-Rexroth Pumps, and GHH-Rand Air-ends. When comparing price, it is easy to see that the Rock Commander line’s pricing falls well below the competition without sacrificing quality. Regarding parts availability, we pride ourselves in having an extensive parts inventory available in Louisville, KY. We understand that down-time waiting on parts is lost revenue, and we will do everything in our power to make sure you are up and running.

We believe the smartest thing in a rock drill should be the operator. There are no onboard computers or expensive PLC units to fail and cost you downtime. Simple systems equal simple maintenance and when there is a problem, trouble-shooting does not require a lap top and a technician. Your current mechanics can maintain the Rock Commander drills with ease.

With 35 years of experience in the rock drilling industry Larmee Equipment & Supply, Inc., the Parent company of Junjin America LLC, lends its knowledge and experience to continuously improve systems and applications related to the drilling industry. We value our customers’ needs and opinions and took those into careful consideration before introducing the Rock Commander line of drills.

To find what Rock Commander model is right for you. Please give us a call at 502-244-0004, or come visit us in Louisville, KY.
