Abstract: 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).

Abstract: Positional relationship among the first link support shaft (85), the second link support shaft (86), the first arm support shaft (88) and the second arm support shaft (89) is set such that an upper portion of the first lift link (81) comes into substantial agreement with a rear end of the machine body (1), when the upper free end of the first lift link (81) is pivoted maximally rearward in the course of transition of the arm (77) from a lowermost state realized lifting down the arm (77) to an uppermost state realized by lifting up the arm (77).

Abstract: 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.

Abstract: A skid steer loader comprises: a main frame assembly (1); a boom assembly (2); a pair of right and left travel assemblies (3); a cabin (4) mounted so as to be capable of being tilted; an engine (5) located so as to be oriented in a longitudinal direction and at a location closer to a rear; a hydrostatic transmission (8) and an oil pump (9) connected to a front portion of the engine (5). A utility space is defined between the oil pump (9) and a bottom (1a) of the main frame assembly (1). A fuel tank (6) and a hydraulic tank (7) are located on the bottom of the main frame assembly (1) and to one lateral side and to the other lateral side respectively of the engine (5) and forwardly of the engine (5) in a vicinity of the oil pump (9). At least one of the fuel tank (6) and the hydraulic tank (7) has a laterally extending portion that projects into the utility space.

Abstract: An improvement of a loader work machine is disclosed. A machine body frame includes a frame body having a bottom wall and a pair or right/left side walls, and a pair of right/left support frame members connected to a rear end of the frame body. A cabin is mounted on the machine body frame. A transverse connecting member is disposed rearwardly of the cabin for connecting the pair of right/left support frame members to right/left sides thereof, respectively. A pair of right/left arms are disposed on right/left sides of the machine body frame, with base portions thereof being vertically pivotally supported to the pair of right/left support frame members, respectively. A pair of right/left arm cylinders are provided between the base portions of the arms and the rear portions of the machine body frame for lifting up/down the arms. A hood 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, for housing an engine.

Abstract: A loader work machine includes: a first lift link (81) and a second lift links (82) disposed forwardly of the first lift link (81) for vertically pivotally supporting a base portion of an arm (77) at a rear upper portion of a machine body frame (1); an arm cylinder (79) provided between the base portion of the arm (77) and a rear lower portion of the machine body frame for lifting up/down the arm (77); a first link support shaft (85) for pivotally supporting a lower base portion of the first lift link (81) to the machine body frame (1); a second link support shaft (86) for pivotally connecting a base portion of the second lift link (82) to the machine body frame (1), at a position forwardly of the first link support shaft; a first arm support shaft (88) for pivotally supporting a base portion of the arm (77) to an upper free end of the first lift link (81); a second arm support shaft (89) for pivotally connecting a base portion of the arm (77) to a free end of the second lift link (82), at a position forwardl
