Patent number: 7686241Abstract: In a jaw crusher, cheek plates are mounted on side wall plates of a crusher frame by mounting bolts, and the mounting bolt adjacent to the outlet of the jaw crusher can be covered with the swing jaw by adjustment of an outlet gap-adjusting link mechanism. When the jaw crusher is in operation, the mounting bolt is covered by the swing jaw to avoid contact with raw materials, so that abrasion of and damages to the mounting bolt can be prevented. Thus, a longer lifetime of the jaw crusher can be promoted. Besides, since abrasion of and damages to the mounting bolt can be prevented, a mounting structure of the cheek plate can be stronger.Type: GrantFiled: August 24, 2006Date of Patent: March 30, 2010Assignee: Komatsu Ltd.Inventors: Tooru Nakayama, Ryoichi Togashi, Kouzo Suzuki
