Outrigger Design

Stetter Batching Plant Stability and space efficiency.


Schwing has patented a number of outrigger designs which neither compromise on stability nor space.


Wanting to both avoid the instability of multi-telescoping outriggers whilst at the same time keeping the outrigger internal storage from compromising the pumping technology, Schwing has patented a number of designs for different sized machines that solve both problems.



H OutriggersFront outriggers


H-outriggers - front


With the H-outriggers, the outriggers move left and right at a 90° angle to the machine. The two outrigger boxes which house the outrigger beams lie next to each other. Like all other SCHWING outriggers, the H-outriggers are only single-telescoped.

X-outriggers


Easyflex X-outriggers are used by SCHWING in the class S 24 X to S 36 X. Here, the two outrigger boxes with the beams lie one on the other in an X-shape. For smaller machines with single-telescopic support only a straight extension beam moves out of the box. For larger machines with larger spans, the X-support has to be telescoped 2 to 3 times in order to achieve the required outreach while optimally utilizing the limited space available. SCHWING uses only 1-fold telescopic supports for its truck-mounted concrete pumps, as they have less play and higher rigidity.

SX-outriggers


Easyflex

The SX outriggers developed and patented by SCHWING are curved and can thus occupy a significantly longer space in the machine than a classic X-outrigger. Even larger outrigger spreads can be realized with a single extension beam. Multiple telescoping outriggers necessarily have a certain amount of play between the individual outrigger segments in order to enable the extension movements in the first place. The single extension beam of the SCHWING SX-outriggers is significantly warp-resistant and more robust in comparison. This ensures steadiness when pumping and less boom “bounce”. Another advantage: the center of the frame is not blocked by outriggers and remains free. As a result, the efficient long-stroke pump kit P2525 can also be installed in smaller truck-mounted concrete pumps from SCHWING. The SX-outriggers allows intermediate positions (see also EASyflex).

SXF-outriggers


Easyflex With the SXF-outriggers developed and patented by SCHWING, the advantages of the curved SX outriggers can also be used for machines with significantly more than 60 meters reach. Instead of the usual multi-telescopic outriggers in this machine class, a one-piece push-out beam is used as with the SX outriggers, which is additionally combined with a hinged element. This results in comparison to multi-telescopic outriggers in a higher stability and more steadiness when pumping.

Rear outriggers


Vertical jacks


Easyflex For smaller truck-mounted concrete pumps and truck-mixer pumps from SCHIWNG-Stetter, it is sufficient if the rear outriggers are only lowered vertically, without the need to be extended horizontally. The outriggers remains at the rear within the vehicle width. This reduces the space requirement and the machine can be set-up in places that are not accessible to other concrete pumps.

H-outriggers - rear


Easyflex With the H-outriggers, the outrigger extends left and right at a 90° angle to the machine. The two outrigger boxes which house the outrigger beams lie next to each other. Like all other SCHWING outriggers, the H-outriggers telescope only once. Compared to a folding outrigger, the H-outrigger offers two major advantages: The lateral extension of the outriggers results in an extremely small footprint. This allows concrete pumps with H-outriggers to work in locations where other concrete pumps cannot be set-up. In addition, there is plenty of storage space for accessories and hoses on both sides thanks to the rear H configuration.

EasyflexSwing-out outriggers


Swing-out outriggers are used on truck-mounted concrete pumps where, due to their size, H-outriggers can no longer be structurally implemented. For reasons of weight, the articulation points of the folding elements are positioned as close as possible to the turret. The outrigger swing out using hydraulic cylinders.
