Publication number: 20240052584Abstract: Provided is a block compactor equipped with a brake mechanism capable of securely locking rollers with a simple structure and stably maintaining a locked state and an unlocked state even when exposed to vibration. A brake pad 12 is fixed to a lower end portion of a brake shaft 11 and is configured to be rotatable together with the brake shaft 11 between two rollers 5 adjacent in the front and rear. By rotating a brake lever 13, the brake pad 12 can be switched between an unlocked state in which the brake pad 12 does not contact with the outer circumferential surfaces of the rollers 5, and the rollers 5 are free to rotate, and a locked state in which the brake pad 12 contacts with the outer circumferential surfaces of the rollers 5, and the rollers 5 cannot rotate with the friction force.Type: ApplicationFiled: February 6, 2023Publication date: February 15, 2024Inventors: Kenichi NAGASAWA, Masaya SEKIGUCHI, Yuichi NAKAGOMI, Yuta SAKAI
