Schwing Adds New Boom Pump

Schwing Adds New Boom Pump

October 6, 2014 – St. Paul, Minn.


Schwing has expanded their boom pump lineup with a new model, bringing the Schwing truck-mounted concrete pump with placing boom line to a total of 16 different models. The S 20 offers a unique boom design in a compact package, affording pumpers, concrete contractors and specialty contractors a versatile tool to expand concrete pumping possibilities while also performing conventional work.


The four-section Double Z boom offers a total of 820 degrees of articulation with 270 degrees at both the third and fourth sections, allowing many possible configurations in confined spaces. Combined with a 12-foot 7-inch unfolding height, the S20 can be used indoors, under overhead structures and in tunnels. The standard truck is a Kenworth T370 with 330 hp and automatic transmission. Overall reach of the boom is 63 feet 8 inches vertically and 51 feet 10 inches horizontally. The boom can rotate 370 degrees in either direction, enhancing versatility on tight projects. The boom is equipped with full five-inch pipe.

The S 20’s utilization benefits from its convenient ability to perform as a line pump with a standard back-end 180-degree rotating outlet. The unit also features excellent storage for clamps and additional system with fold down sideboard access on the driver’s side to a 13-foot loading deck.

The standard pump kit is the 2023-3 110/75 SC with 124 cubic yards per hour output, operating through nine-inch diameter pumping cylinders. The twin-cylinder all-hydraulic unit sequences the pumping cylinders through the proven M Rock Valve, providing maximum sealing efficiency in a totally rebuildable valve with a minimum of moving parts. Contractors can pump with confidence in all situations with the S20, handling mixes with up 2.5-inch aggregate and applying up to 1095 psi on the concrete.

Manually extending outriggers lower hydraulically, applying only 38 psi soil pressure with dunnage on the front and 15 psi on the rear. Spacing is 12 feet 8 inches in the front and 7 feet 3 inches in the rear, for easy setup on crowded job sites.
