Self-Climbing Mast
Description
When building floors are finished with poured concrete,
the placing boom must rise to the next level.
This can be done by means of a crane. If no crane is
available, hydraulic climbing equipment must be used.
This allows the placing boom and the boom tower to be
lifted gradually or, in other words, “to climb” up to the
next concreting level.
Floor frames (Item 1 Figure 32) are installed in open-
ings of the finished floors (Item 2) to guide the boom
tower (Item 3).
The climbing floor frames transfer the occurring forces
to the structure and carry the hydraulic cylinders (Item
4 Figure 32) used for raising the boom tower and the
placing boom.
During the climbing procedure, three climbing floor
frames must be installed, with the lowermost frame car-
rying the climbing equipment.
The power pack of the placing boom supplies oil to the
hydraulic cylinders of the climbing equipment.
The hydraulic cylinders are controlled by an addition-
al control valve in the placing boom control block. The
valve is actuated via a cable remote control.
