- The mechanism of a gasoline-powered rock drill is a testament to human ingenuity. It typically consists of a robust gasoline engine that drives a hydraulic or pneumatic system, which in turn operates the drilling mechanism. The high torque generated by the gasoline engine enables the drill to penetrate even the hardest rock formations with ease, making it indispensable in deep mining operations and large-scale construction projects.

Gratings & Covers






molded frp gratings are manufactured in a one piece construction which results in a bi-directionally strong product. This allows openings for piping or cables in the grating of up to 10” without any additional support required (may vary depending on grating depth and location of opening). During the molded manufacturing process, the continuous fiberglass rovings are completely covered in a high percentage of resin, 65% by volume. With this high resin content, molded gratings are the most chemically resistant gratings offered and are often used in caustic chemical environments without hesitation.
