Abstract

PURPOSE: To increase the stability on the occasion of back-tilted drive by a method wherein a base beam and a horizontal beam provided with a rear jack are connected through the intermediary of a pin and further cylinder device is provided between both beams.
CONSTITUTION: The horizontal beam 15B is swiveled by extending the rod 16b of an oil-hydraulic cylinder device 16, the rod 16b is fixed when the center of axis of the horizontal beam 15B accords with that of the base beam 15A and the rear jack 6 of the horizontal beam 15B is extended and made to touch the ground. When the back-tilted drive is performed, the rod 16d is contracted, thereby the horizontal beam 15B is depressed at about 45° in the direction of the rear of an upper slewing body 1A, and then the rod 16b is fixed.
