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.

SCHWING GMBH – Separate Placing Booms SPB 02/2014

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.

SCHWING GMBH – Separate Placing Booms SPB 02/2014

To be fixed 2-3 floors slabs (depending on the floor height) to ensure the

requested stability. The boom can be mounted on a 20 m column inside the

building with a max. free standing height of 15 m above the last floor frame .

1x Hydraulic climbing device (75 Kg each

cylinder)

and placing boom, consisting of:

1 set climbing cylinders actuated by

means of a hand lever at the control

block or via remote control - push button

and approx. 15 m cable, suspensions

with socket pins.

3xLadder section, 4 m long (43 kg)

with back protection

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.

SCHWING GMBH – Separate Placing Booms SPB 02/2014

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.
