Abstract
A swivel type working vehicle includes a running device (), a swivel base () mounted on the running device to be swivelable about a vertical swivel axis (), a swing bracket () supported to be swingable about a vertical axis by a flange unit () disposed at a front end of the swivel base, a boom () having a proximal end (B) thereof attached to the swing bracket to be swingable about a horizontal axis (), a boom cylinder () having one end thereof connected to the swing bracket and the other end to the boom for swinging the boom, a hydraulic pressure takeoff device () disposed in a distal end region (C) of the boom, and hydraulic pressure takeoff pipes (A,B) for supplying hydraulic pressure to the hydraulic pressure takeoff device (). The boom () is a hollow box having a front wall (), a left wall (A), a right wall (B) and a rear wall () extending longitudinally of the boom. The boom cylinder () is disposed outside the boom to extend along the rear wall of the boom. The hydraulic pressure takeoff pipes (A,B) extend from the swivel base through a proximal opening () formed adjacent the proximal end (B) into the boom to reach the hydraulic pressure takeoff device.
