Patent number: 8821104Abstract: A loader work machine is disclosed in which a base portion of each of right/left arms (77) is received by an arm support portion (164) of a first lift link (81) and pivotally supported by a first arm shaft (88), and a hydraulic pipe arrangement (167) connected to a hydraulic actuator (98) extend through an support frame (11) from inside to outside of its inner wall (12), and toward an arm (77). The base portion of the arm (77) is supported to the arm support portion (164) at a position adjacent a link outer wall (157) in a transverse direction so that a hose accommodation space (165) is formed between a link inner wall (156) and an internal side face of the base portion of the arm (77). The hydraulic pipe arrangement (167) runs frontward of the first arm shaft (88) and a first link shaft (85), and is disposed in the hose accommodation space (165).Type: GrantFiled: March 26, 2009Date of Patent: September 2, 2014Assignee: Kubota CorporationInventors: Toyoaki Yasuda, Masanori Fujino, Toshihiko Takemura, Yasuo Nakata, Yoshitaka Matsubara, Yoshihiro Ueda, Yuuki Takano, Yusuke Kawai, Ryohei Sumiyoshi, Hiroyuki Anami, Naoya Muramoto, Kenji Mitsui, Youhei Kawano, Takeshi Ikumura

Patent number: 8342789Abstract: A hood for a loader work machine is provided at the rear end of the frame body and downwardly of the transverse connecting member between the pair of right/left support frame members. The transverse connecting member includes a front wall plate and an upper wall plate projecting rearward from an upper end of the front wall plate. The upper wall plate of the transverse connecting member is disposed more downwardly than the vertical center of the cabin. A rear portion of the upper wall plate is inclined downwardly rearward. A hood upper wall is provided for covering a rear upper side between the pair of right/left support frame members. A front end portion of the hood upper wall is connected to the rear portion of the upper wall plate of the transverse connecting member. The hood upper wall is inclined downwardly rearward in correspondence with the rear portion of the upper wall plate.Type: GrantFiled: March 25, 2009Date of Patent: January 1, 2013Assignee: Kubota CorporationInventors: Toyoaki Yasuda, Masanori Fujino, Toshihiko Takemura, Yasuo Nakata, Yoshitaka Matsubara, Yoshihiro Ueda, Yuuki Takano, Yusuke Kawai, Ryohei Sumiyoshi, Hiroyuki Anami, Naoya Muramoto, Kenji Mitsui, Youhei Kawano, Takeshi Ikumura
