TURNING TYPE EXCAVATING WORK VEHICLE

PURPOSE:To dispense with piping between a traveling motor and a drain block by arranging a drain aggregate joint directly on a swivel joint as well as to enable rational piping of a drain from respective hydraulic apparatuses by arranging the drain aggregate joint in a center position of the swivel joint. CONSTITUTION:In a small turning type excavating work vehicle which can turn an almost circular turning frame 12 within a width of a crawler type traveling device, a drain aggregate joint 1 is arranged in a center positional upper part of a swivel joint S arranged in a rotary center position of the turning frame 12. A joint is protrusively arranged in a radial shape of the drain aggregate joint 1. A rotary pivotal part of an opening and closing hood is supported so as to be adjustable vertically, laterally and longitudinally. A canopy column also serving as a balance weight is erected in a position opposed to an engine E and an operating oil tank R, and a battery housing part is arranged in a part of the canopy column.
