• It is used for the standard butting test of JIS soil and for the automatic butting of cbr specimens with mechanical accuracy.
• Compared to conventional manual rammer clashing, it saves a lot of effort and produces correct clumping effect.
• ・ Soil sharpening and cbr test sharpening can be easily switched by replacing the friction cam and rammer.
• ・ The rotation table is automatically rotated with each blow, and the center of the specimen is also automatically clamped and cemented, so that the specimen is evenly clamped on the whole surface and prepared for the creation of a specimen with uniform density.
• ・ Falling and pulling up of the weight are performed by the actuating cam, and the prescribed drop height and free fall are always maintained regardless of the lowering of the butting surface of the sample.
• Any set of drop rotation and stop can be freely selected.
