Crane transversely adjustable supports - has two further supports attached to arms fixed to central mobile crane body

摘要

The support base for the crane is formed solely from the two adjustable transverse supports in conjunction with the non-transversely adjustable supports on the crane's carriage. The adjustable supports form the ends of a diagonal of the supports. The diagonal forms an angle of up to 90 deg. with the vertical longitudinal central plane. This angle is greater than the acute angle between this plane and the rother diagonal of the support base. The central body of the crane carriage is connected with the frame sections at the two ends of the carriage by two paris of struts. The turntable for the crane superstructure is seated on the central body.
