A drilling company needed to update the design of their man-portable drill rig. This company drills holes into bedrock for pilings used in residential foundations. Due to the nature of the job, high vibrations and a very dirty environment were problematic. PBC Linear was asked to help implement their new drilling equipment light enough for two men to handle, yet robust enough to withstand drilling into rock. The goal was to improve precision by 10-percent and the life cycle by 50-percent.
