Heavy-Duty Structural Extension with Rotating Platform

The superstructure together with the turntable is a single power structure. The superstructure consists of two longitudinal trusses, front and rear frames. The front post is attached to the front frame by means of a spherical support. The head of the front post is connected to the superstructure trusses by two tubular struts. For increased reliability, each strut is compressed by two cables using inbuilt hydraulic devices.
