The outriggers consist of hydraulically-actuated, box-type
beams and vertical jack cylinders, one at each corner of
the crane. The outriggers provide a rigid, four-point
platform capable of supporting the crane and its
maximum load capacity.
Air/transmission, electrical and hydraulic swivels route
the air, transmission, electrical and hydraulic circuits
from the superstructure to the carrier frame. These
swivels are mounted as a single assembly above the
turntable bearing and drive.
