May 02, 2013 · Section 1926.702(e)(1) (Concrete pumping systems) requires that "Concrete pumping systems using discharge pipes shall be provided with pipe supports designed for 100 percent overload." Many other OSHA standards impose additional requirements for safely using concrete boom pump trucks to place concrete in construction, including the following
Dec 01, 2011 · The pumping unit is bolted to the chassis of the truck and, through its connection to the truck's engine, works like an alternating pump, consisting of two actuators and four pressure chambers. The alternative motion of the pistons forces the concrete to flow into a pipe connected to the boom; this is clearly visible in Fig. 2 .
Jan 01, 2011 · The calculation of the damping parameters (, and the concentrated terms) was done minimizing the difference between estimated damping and model damping in different configurations. This numerical model can simulate the typical operating condition of concrete pump booms. 4.THE CONCRETE PUMPING UNIT ( y O x ) .
Jan 01, 2017 · 3. Truck Mounted Concrete Pump Boom Modeling by Virtual Prototyping Technology The established 3D model of a truck mounted concrete pump boom is shown in Figure 3. The system is built up by 4 booms, several links, hydraulic actuators, joints, and other components.
2.THE TRUCK MOUNTED PUMP Concrete boom pumps are complex dynamic systems with a variable number of segments linked together by kinematic joints and moved by hydraulic actuators. In this way the end-activator, i.e. the boom tip h ousing the device for placing the concrete, may be very far from the pump or in very high place (Figure 1).
Compact design – 56m pump mounted on 4-axle truck. Active boom vibration control technology (ABC): All-position active vibration reduction technology of boom, reducing vibration by 50%. More stable boom, more safety. Boom intelligent damping technology: The soft control of booms in starting, slewing and stopping reduces the impacting vibration of booms and therefore makes the vehicle operate more …
Apr 01, 2017 · The control device forms the central component of the Ergonic 2.0® system by Putzmeister, which is responsible for the monitoring and control of the truck-mounted concrete pump. Ergonic 2.0® system. Ergonic 2.0® is the latest microprocessor-supported system for the control of concrete pumps and booms by Putzmeister.

In order to raise operator comfort levels on truck-mounted concrete pumps with large booms, the company has launched an innovative vibration damping system. Schwing, in partnership with Baumer Electric AG, has developed a new strain sensor with an IP69K protection rating and an exceptionally broad measuring range to provide precise signaling of deflections as they occur in the boom.
damping. These characteristics, coupled with the dynamic i.e. the boom tip housing the device for placing the concrete, may be very far from the pump or The Truck Mounted Concrete Boom Pump
HZS series concrete batching plant is a plant which is forced and high efficiency, it is an ideal equipment to produce the commercial concrete which is used to produce plastic concrete, dry concrete and so on. Because of its high efficiency, it is being widely used in big and medium scale construction project, road and bridge, and the factories which produces the pre-fabricated concrete component.
Oct 10, 1990 · Concrete-pumping device comprising a frame, a number of pump cylinders mounted on the frame which comprise a pump opening close to one end, sealed pump pistons which are guided slidably in the pump cylinders toward and away from the pumping device and which are each coupled to reciprocal driving to the plunger of a coaxially arranged hydraulic jack, hydraulic switching means for …
5.1 Truck engine does not start _____29 5.2 Pump unit does not start (without hydraulic pressure) _____29 The concrete pump works as follows: The tilting cylinders are in pos. S13. During the pumping the Safety devices may not be altered resp. removed and are to be used in a correct manner.
