Humboldt’s HCM-3250 Series Concrete Compression Machines are built to be one of the strongest machines in its class, and are able to handle even the harshest testing regimen with ease. American-built, the HCM-3250 features a rigid, steel-welded load frame with four-inch thick upper and lower crossheads and a large, seven-inch diameter ram. The load frame is manufactured with structural steel, side members, and solid steel crossheads, which utilize a wrap-around box construction where each corner is fully-welded on both the inside and outside crosshead seams. This provides the rugged stability needed for accurate and repeatable test results year after year.
HCM-3250 compression machines come configured ready-to-test 6" x 12" concrete cylinders. In addition to the use of optional spacers and accessories, the machines can be configured to test 2" x 4", 3" x 6", and 4" x 8" cylinders, beams, 2-inch cement cubes, as well as splitting and tensile-strength tests.
Available with either a digital indicator or a manual hydraulic pump. Humboldt’s exceptional HCM-5090 digital indicator has a quiet, continuous-duty hydraulic pump equipped with a pressure-compensated loading control valve. Each component is manufactured to ISO 9001 international quality standards. Both the digital controller and hydraulic pump are positioned on the right side of the compression machine for easy access, increased productivity, and safer operation.
HCM-3250 machines are also available with automatic controller and pump configurations featuring Humboldt’s HCM-5080 Automatic Pump and Controller System, delivering one of the most versatile, accurate, and user-friendly concrete compression machine controllers available today.
