1 Stationary Placing Boom:
1.1 General
The limits of concrete placement continuously expand with the application of a
Schwing concrete pump and placing boom combination. Now imagine where you
want the concrete to be placed...at what rate... and let the Schwing product
specialists plan a distribution system with the site manager.
The possibilities are endless with the various booms sizes available, the mounting
options and the number and sizes of booms that can be engineered into a project.
The net result is systematic concrete placement you can count on while increasing
placement rates by as much as 50-percent over other methods.
Labour requirements are minimal – one person operates the placing boom for
uniform concrete placement in wall, column and deck forms – less raking and
finishing time is required because of the precise placement. Continuous flow also
results in higher quality concrete.
Added time savings are realized by the tower crane being free to handle other
lifting operations.
Years ago already the trend to rationalization and short completion periods led to
the use of placing booms for the construction of large-scale buildings. Based on
the experience in the manufacture of concrete placing equipment, SCHWING was
able to offer their trendsetting equipment at a very early stage. As far back as in
1969 where the first SCHWING separate placing boom was put into operation by
Ph. Holzmann in the joint venture Asenwald Stuttgart.
The experience gained through all these years on a great number of construction
sites all over the world enabled SCHWING consulting engineers gain the
experience to offer the optimum concrete placing method for every site.
One way to place concrete quickly and economically is the use of separate
placing booms in conjunction with efficient concrete pumps. The placing booms
with the designation SPB and those of truck-mounted concrete pumps are of
equal design. That is why the placing booms SPB 30 through SPB 35 can be used
for stationary as well as on truck mounted pumps.

1.3 Technical data and options
Boom of stable box-type construction, 4-stage hydraulic folding in vertical plane
with attached pipeline, pivoted on a swivelling slewing column, operation of the
boom by means of hand levers or installed electric remote control cable, end hose
and connecting line for connection to the delivery pipeline. Trestle-pin connection
for quick separation when repositioning the placing boom. First boom section with
pin joint.
Powering of the hydraulic pump for hydraulic actuation of all boom movements is
made by an electric motor. The complete power unit including the hydraulic tank
and control box is installed near the pedestal.

3 Climbing procedure
During the climbing operations, the boom column must be
guided and supported by three climbing guide frames.
These frames transfer the occurring forces into the
concrete structure and maintain the stability (Fig 1).
The climbing equipment is always installed on the
lowermost climbing frame.
1. Attach the lifting arms 2 to both climbing cylinders 4 (Fig. 2) and secure the
pins 3.

2. Place the climbing cylinders on the supports of
the lowermost guide frame (Fig. 1), insert the
lifting pins 1 in position "A" and secure. In this
position, the climbing cylinders can be
extended and retracted without the boom
column being lifted (for bleeding).
3. Extend the climbing cylinders slowly to the
limit top. The boom column and the placing
boom are raised in the process.
4. When the climbing cylinders are fully extended, insert a supporting pin 1 (Fig.
2) on both sides above the guide frame.
5. The safety latches 2 (Fig. 2) of the supporting pins
must be inserted into the next higher bore of the
boom column − Relieve the climbing cylinders by
retracting them slowly a short distance. The load of
the boom column and the placing boom is now
borne by the supporting pins.
6. Retract the climbing cylinders completely (Fig. 3).
7. Withdraw the lifting pins and insert into the
next hole (Fig. 3).
8. The next lifting procedure can now be started.
9. Repeat these steps until the boom column has
reached the desired height.
