SIMCO 2400-SK-1 – An Evolution of Superior Drilling Rig Engineering

The SIMCO 2400-SK1 has been one of the most popular and versatile drilling rigs in the SIMCO line since early in their 50-year history. Introduced in 1971 shortly after the company opened for business, this tough auger rig was touted as a simple to operate, economical to own, compact and well-engineered piece of equipment. As the years progressed, the team at SIMCO continued to improve on the popular platform.

“It’s not often that the two sayings ‘You’ve come a long way, baby,’ and ‘If it ain’t broke, don’t fix it’ can be equally applied to the same product,” said Richard Clarke, Director of Marketing at SIMCO. “However, in the case of the 2400-SK1 model drill from SIMCO, both cases can apply.”

Although the rig’s power, performance and versatility have been greatly increased over the past 50 years, these same reliable traits are still true today.

“When you have a product that works as well as the 2400,” said Clarke, “Keeping it current with industry changes and customer demand is easier than engineering from scratch.”
