Hydraulic Versus High Frequency-Wall and Wire Saw Technology in the Concrete Sawing and Drilling Industry

摘要

When cutting large concrete areas, a wall or wire saw can be the ideal piece of equipment for the job. Wall and wire saws have typically been powered by hydraulics, but now contractors have a choice between hydraulic or high frequency machines. High frequency technology has been around for over 30 years, though it took some time for this technology to become fully developed. Products were limited and not readily available in the marketplace, therefore it took a while to break into the hydraulic-dominated construction industry. It was not until the 2000s, when high frequency equipment was more refined, that acceptance of this technology grew. Since then, various high frequency products have emerged into the concrete cutting and drilling market, including high frequency wall and wire saws. It is important to look at the differences in hydraulic and high frequency wall and wire saws to understand how each operates, their maintenance needs and modern techniques. This will enable cutting contractors to best determine which is better for a particular project or for their fleet.
