EDCO - Equipment Development Company has always created long-lasting equipment that solves many problems.
In 1959 EDCO began as a manufacturing arm of Rental Tools & Equipment outside Washington, DC. EDCO founders Leo Swan and Ed Harding were employees of RT&E, and discovered the biggest issue their rental customers commonly had – leveling concrete floors. At that time, the only ways to level and smooth concrete surfaces were limited to one’s hands or crudely modified buffing machines. To help their customers, Leo, Ed and RT&E owner John Doran, created the modern day concrete floor grinder. Eventually, with this grinder as their cornerstone, Leo and Ed founded EDCO; a manufacturer of “Rental-Tough” products.
As you see below, EDCO Grinders have evolved since 1959, but EDCO Magna-Trap® Grinders have always kept the same principals – long-lasting equipment that solves many problems.
The History of
Slide through the interactive pictures below to watch the evolution of EDCO grinders:
Past: The very first EDCO 2-Disc Floor Grinder model. This lone grinder was originally built just to satisfy the demand of Rental Tool & Equipment‘s local customers. The demand proved to be worldwide.
Present: Like the 1950s Grinder, the current 2-Disc Floor Grinder is long lasting and solves many surface preparation issues. This edition is more productive, easy-to-operate and is part of the EDCO Magna-Trap® family of grinders.
Past: A 1960’s photo shoot with an early edition EDCO grinder. Notice the lack of safety equipment wore.
Present: A present day photo used in several EDCO ads. Today’s surface preparation workforce uses eye, air and ear protection.
Past: Vintage EDCO Grinder shown on a concrete slab. Adding weight helps the machine grind. Customers used to pile sandbags onto the machine for extra weight.
Present: Current EDCO Magna-Trap® Grinder shown on a concrete slab. Current grinders have built-in weight trays for added weight, making the machine more productive.
Past: EDCO’s 1st logo appearing on the front of the grinder. Before everyone learned about silicosis and other lung diseases, surface prep machines did not come with dust suppression guards around grinding discs.
Present: EDCO’s current logo and the Magna-Trap® brand logo. All EDCO products come with dust suppression shrouds and vacuum ports. EDCO vacuum systems eliminate 99% of harmful airborne dust.
Past: Completed Grinder inside EDCO’s first manufacturing headquarters in Sliver Spring, MD. Founder Leo Swan jokingly compares manufacturing there as, “like working in a blacksmith’s shop.”
Present: Completed Magna-Trap® Grinder inside the testing area of EDCO’s current manufacturing headquarters in Frederick, MD. This high-tech facility is where all EDCO “Stayed In America” products are made.
Past: 1970’s EDCO Grinder smoothing concrete with grinding stones. Old grinding accessories were limited in applications and impacted the surface unevenly.
Present: 2016 EDCO Magna-Trap® Grinder removing waterproof membrane with PCD Tooling. Current EDCO grinding tools are versatile, solving lots of applications. The unique Magna-Trap® leveling system lets tooling evenly impact the surface for high production.
Past: EDCO gasoline grinder resurfacing a parking lot. Grinders produce high volumes of dust. Before dust prevention was invented, grinder operators were forced to clean up debris after resurfacing.
Present: EDCO Magna-Trap® gasoline grinder resurfacing a parking lot. Proper dust suppression systems, like the pictured EDCO Vac-200, captures most surface dust created by grinding, drastically reducing job site cleanup times.
For almost 60 years, EDCO Grinders have been ideal for all kinds of surface preparation tasks including smoothing, cleaning, coating removal and leveling concrete surfaces.
