Dormir lo suficiente
Nunca trabaje una máquina bajo la influencia de drogas o alcohol
Inspección alrededor de la máquina
Revisar el manual de operación y mantenimiento, en la sección de mantenimiento diario o cada 10 horas
Al revisar la máquina utilice la regla de los tres puntos
but obviously from the same family

...looks familiar!

1967

1927 - first patent on a mechanical concrete pump

The days of black & white...

....but now in 3-D and colour

world’s first “Superboom”

1973 - KVM 45

1960 - World’s first truck pump with boom

Release the boom tie-down strap
1. Pull the lock in the direction of the small
white arrow until it is clear of the ratchet
gear.
2. Pull out and up on the handle in the direct-
tion of the curved arrow until it is position-
ed straight up. Now you can pull the strap
out of the ratchet assembly.
Before proceeding, understand how the boom
setup is to be done by reading the information
on boom setup beginning on page 4 of the
Safety Manual which is in the Operation Manual.

Pressure reducing valve(2023)(high flow twin circuit)

E-stop station

Dampener Valve

Dampener adjustment: (single circuit units only)
Turn clockwise to reduce the speed of the rock cylinder; turn counterclockwise to increase the speed of the rock cylinder.

Air Regulator

Hydraulic pumps

Directional control valves

Early production MPS valve

Base plate for MPS

Remote control receptacle

E-stop station

Control panel w/E-stop station

Q-max

Q-min adjustment screw

Main return filter

Concrete pump For / Rev selector valve

Manual stroke limiter (rexroth style)

Stroke Limiter

Manual stroke limiter

Stroke Limiter Adjustment:
Turn clockwise to reduce the strokes per minute; turn counterclockwise to increase the strokes per minute.

For single-circuit pumps, this valve will not work unless there is at least 50-60 bar of pressure built up in the concrete pump circuit. Twin-circuit pumps do not have this restriction.

S3 valve

S2 valve

S1 valve

Manual override

Electric stroke limiter(Hartman style)

Soft switch

Pressure reducing valve
(twin circuits units only)

Accumulator control manifold & S3 valve
(twin circuit units only)

Fast switch assembly (single circuit units only)

If your unit does not have a shutoff valve, order one using part #10004680 (valve) and #30303432 (tube). Contact the Schwing Service Department for installation instructions.

If you can’t wait for a shutoff valve, you will need to remove one of the hoses from the agitator motor, and plug the hose and the open fitting with approved hydraulic dead plugs.

Do not substitute other plugs, such as a steel bearing, inside a cap fitting.
