Claims11
A hydraulic shovel comprising a piping structure, wherein the piping structure comprises at least one flexible hose and a guide cylinder, wherein an intermediate portion of said at least one flexible hose is slidably insertable into said guide cylinder, and an urging means for urging said hose toward either a direction to move into said guide cylinder or a direction to move out from said guide cylinder so as to form slaking of said hose at a predetermined place.
A piping structure of a working machine comprising at least one flexible hose and a guide cylinder, wherein an intermediate portion of said at least one flexible hose is slidably insertable into said guide cylinder, and an urging means for urging said hose toward either a direction to move into said guide cylinder or a direction to move out from said guide cylinder so as to form slaking of said hose at a predetermined place, wherein a plate member is provided near the open end of said guide cylinder to define the direction of said hose that moves in or out.
A piping structure of a working machine comprising at least one flexible hose and a guide cylinder, wherein an intermediate portion of said at least one flexible hose is slidably insertable into said guide cylinder, and an urging means far urging said hose toward either a direction to move into said guide cylinder or a direction to move out from said guide cylinder so as to form slaking of said hose at a predetermined place, wherein said working machine includes an arm and a working device swingably coupled to an end of said arm, said guide cylinder being provided on said arm, and said hose is passed into said guide cylinder.
