<p><P>PROBLEM TO BE SOLVED: To provide a rudder mounting structure for construction equipment sufficiently durable even when fitted with a heavy rudder. <P>SOLUTION: A reinforcement means 29 divided into upper and lower members 29a, 29b is fixed to a side frame 10c of a vehicle body frame 10 which forms a turning body 2 installed on a traveling body 1 enabling self-traveling so as to be freely turnable, and a mounting member 24 is fixed to outer peripheral faces of the upper and lower members 29a, 29b so as to integrate the upper and lower members 29a, 29b with each other. The rudder 27 is mounted to the mounting member 24 via a passage bracket 20c supporting a floor board 20b of a passage 20. Since a load applied to the side frame 10c as a rotation moment is transmitted from the passage bracket 20c to the reinforcement means 29 via the mounting member 24, then, dispersed to a wide region by the upper and lower members 29a, 29b of the reinforcement means 29 and transmitted to the side frame 10c, the rudder mounting structure can sufficiently endure the load to which the deadweight of the heavy rudder 27 and passage 20 and weight of an operator and worker etc. are added. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
