Abstract
An upper cross beamfor supporting a rear side of a cabfrom below is formed as a separate member from a base frame. This upper cross beamis separably mounted on left and right column portionsE of the base frameby using bolts. Namely, when an engineis mounted to the base frame, the upper cross beamis separated in advance from the base frame. Consequently, at the time of the operation of carrying in the engine, it merely suffices to vertically hoist or lower the engineby use of a crane. It is thereby possible to carry in the enginebetween the column portionsE of the base framewithout being hampered by the upper cross beam
