30K machines were developed with a specific focus on accuracy and maintaining required load pacing rate. The CM-30 compression machine’s load frame incorporates solid steel crossheads and four structural steel side members. Resulting in a fully welded together rigid one-piece load frame. The frame’s rigidity further enhances the unique method by mounting the hydraulic cylinder/piston assembly through the center of the top crosshead. By fully supporting the assembly, this eliminates any lateral movement of the piston under load extension. In addition, the design of the device provides for accurate and repeatable test results. Optional accessories are available, such as: test platen sets, spacers, and machine mounting stand with auxiliary load frame units.
