Figure 6.176 Placement of the lifting
device on the load distribution panels
The pipeline was lifted using a suspension draw system. At the half clamping rings, a
flexible base was fitted between the pipeline covering and the plate of clamping ring. The
suspension draw system consisted of a half clamping ring made from hot-formed P
16.300 plate and ф 48 vertical bars. The bearing binder was made from two HE 300 B
girders and was laid on supporting columns. The draw bar system was installed and the
formed bases welded where the 200 kN hydraulic presses were located. After emplacing
the presses and the 2×U200 movable binders, the system to lift the pipeline was ready
(Figure 6.177).
