4-Section Overhead Roll and Fold®

The innovative Overhead Roll and Fold® boom design works so well on bridges, commercial and industrial work. Hundreds of pumpers and concrete contractors have discovered the versatility of a boom with a main section that articulates 180-degrees. This feature allows the main section to be angled away from the pour so that the boom can be guided horizontally into enclosed areas, positioned vertically for elevated work and stretched out over the cab for flatwork.
And whether you are reaching deep into a structure for a controlled pour or operating flat out on a deck, the operator can maneuver the boom with confidence for efficient and precise placement utilizing an industry-leading 740-degrees of total boom articulation.

Super X Outriggers

Incorporates Schwing’s exclusive Super X Outriggers® that set-up fast and provide a compact and stable platform for pumping.

Exclusive Super X Outriggers® set-up fast and provide maximum stability with a smaller footprint for more effective pumping on tight job sites. These curved front single-stage outriggers telescope out and around obstacles allowing placement of the pump as close to the pour area as possible. This means maximum utilization of the boom reach and more yards of concrete poured from a single set-up. By retracting along the sides of the truck chassis, the Super X Outriggers® allow for the large diameter, long stroking material cylinders down the center of the pump that provide smooth operation and less wear than conventional concrete pumps.


Optional Rear Steer Axle

Schwing’s rear steer option utilizes Mack drive axles which allows the rear steer axle to be covered under the truck warranty.

Get in and out of job sites with confidence thanks to the optional rear steer axle. Often the concrete pump will be driven straight into the placement area and regular truck mixer traffic during the pour will cause a rutted exit. Rear steer acts as a front wheel drive in reverse powering the unit out of the ruts and backing in the desired direction. The system also reduces the turning radius to an industry leading 55-feet. Only available on Schwing S 58 SX and S 61 SX.

Generation 3 Pump Kit

Outperforms every other concrete pump on high visibility projects while also placing millions of yards on everyday pours.

Proper cooling of the hydraulic oil is critical to continuous operation under demanding conditions. In addition, filtration is the single most important method of keeping the hydraulic system operational. That’s why the Schwing G3 design continuously draws hydraulic oil from the tank and circulates it through the filter and high efficiency cooler. Even when the concrete pump is not engaged, this separate hydraulic circuit continues to operate for protection and performance.

Redesigned for 800 LPM of oil, the 3 High Flow Control Block is the brain for the all hydraulic system. The block incorporates the Soft Switch into the relief valve and the accumulator manifold into the S3 spool valve for a compact, simpler design. Multi Port Shifting is an important part of the twin circuit system, which uses accumulator pressure to switch the S3 valve. Faster switching of the S3 translates to smoother pumping. The S3 block and system accumulator are separated from the control block and located near the hopper for easy access.

The material cylinders contain rubber rams that are connected to the differential cylinder rods. One side will push the concrete through the Rock Valve™ while the opposite side will draw concrete from the hopper. Now available with up to 10 inch (250mm) diameter and 98-inch (2500mm) stroke length, G3 pumpkits deliver 30% more concrete with every stroke than competitive brands. Fewer strokes translate to smoother pumping, less wear and longer boom life.

The hydraulic pumps for the concrete pump circuit are bent axis, variable displacement, piston pumps. They are horsepower controlled, which means that as pressure rises towards maximum, the flow can decrease, so the power consumption remains constant. This pump assures that the truck engine will not bog down under difficult pumping conditions. The pump also accepts external signals from the hydraulic stroke limiter for control of the output.

Vector Controls

Valuable operational data at your fingertips to allow monitoring of the pumping process from the remote control box.

Operators are fully informed of the pump’s status even when they are hundreds of feet from the pump. No need to shutdown and return to the pump when an operator can view the following critical information at the remote box:

• Strokes per minute
• Hydraulic pressure
• PTO rpm
• Hydraulic oil temperature
• Hopper grate status
• Local/remote/ram change modes
• Switches out of neutral
• Emergency stop activation
• Low water tank

Significant features for fleet owners include one transmitter box for radio or cable operation, a small battery charger in the truck cab, 8-hour long work cycles with two-way communication, safe radio transmission with frequency hopping, easy change out of transmitters and one system for all types of booms.

A High level alarm notifies the operator of situations that may cause damage to the pump. The VECTOR will activate the Emergency Stop and the operator can evaluate the situation. In all cases the operator has the display on the remote box and the VECTOR graphic displays to assist in diagnosis.

Modular Design

VECTOR is proven durable and reliable, but in the event of physical damage, the modular design allows the entire control box to be unplugged and replaced in the field. All control systems will be fully operational with the replacement controller.

Big Rock Valve™

Big Rock ValveThe Big Rock Valve™ is standard on all boom pumps with booms 31-meters and longer and optional on other models. This feature extends the valve and housing to easily keep up with the requirements of high volume pours even with the harshest mixes. The patented design keeps the Rock Valve™ in adjustment automatically to maintain pressure on the concrete for long-term, trouble-free operation.

EASy Flex One-Sided Outrigger System

Reduce the footprint of selected pumps with one-sided outrigger system that allows full boom extension with safe operation through integration with boom controls.

EASy Flex Outrigging

EASy Flex is the one-sided outrigger system standard on Schwing booms from 38-meter and up. By reducing the footprint of these truck-mounted concrete pumps, contractors have the flexibility to set-up in areas without impeding traffic while allowing the full reach of their booms off one side of the chassis. Depending on the model, various one-sided configurations or partial outrigger set-ups are allowable. These short rigs are integrated into Schwing’s VECTOR Controls. Even during the critical set up phase, VECTOR monitors and ensures the safety of the pump and its operator. The working range limitations are guarded against operator “over-ride” with audible signal and reduced boom speed. When the limit is reached the boom automatically stops. If the operator tries to override the EASy Flex limit with the manual hand valve, the audible signal will sound repeatedly and the boom will stop. The System does not monitor soil pressures, but the system does confirm ground contact before allowing the boom to function.
