Rotary working machine
Ample spaces are secured on a rotating table frame, in front of and behind a control valve. A rotary working machine where a step is placed on a rotating table frame, at the front of the frame, and a control valve is placed below the step. The step has operation levers and pedals mounted on it. The control valve is connected to the operation levers and the pedals to perform drive control of a hydraulic actuator, and is placed at an incline so as to be high at the front and low at the rear.
1. A rotary working machine comprising:
a rotating table frame;
a step arranged at a front part of the rotating table frame;
a PTO operation pedal arranged near a middle front part of the step;
a swing pedal arranged near the middle front part of the step;
a pair of left and right travel operation levers arranged between the PTO operation pedal and the swing pedal so as to project upwardly;
a bracket arranged at the front part of the rotating table frame;
a control valve mounted to the bracket and operably connected to the travel operation levers, the PTO operation pedal and the swing pedal, and wherein the control valve is configured to perform drive control of a hydraulic actuator; and
a pedal base arranged on an upper end of the bracket,
wherein the control valve is arranged to be inclined with respect to the rotating table frame at a lower side of the step so that a first end of the control valve is higher than a second end of the control valve,
wherein the PTO operation pedal, the swing pedal and the travel operation levers are each supported in a freely front and back turning manner by a supporting point axis, and wherein the PTO operation pedal, the swing pedal and the travel operation levers are operably connected to the control valve by way of a link mechanism arranged on the pedal base.
2. The rotary working machine according to claim 1 , wherein a reservoir tank is arranged on the second side of the control valve.
