摘要： An articulated aerial device comprises a base and lower, middle and upper beams pivotally connected to one another, the lower beam being pivotally connected to the base. An upper linkage mechanism pivotally interconnects the upper and middle beams and a hydraulic cylinder is connected to the upper linkage for swinging the upper and middle beams with respect to one another. A Z-shaped linkage pivotally interconnects the base, the lower beam and the middle beam. A lower hydraulic cylinder is connected at one of its ends to the base and at the other of its ends to the Z-shaped linkage. Extension of the lower hydraulic cylinder causes the lower beam to swing with respect to the base and simultaneously causes the middle beam to swing with respect to the lower beam.
