Higher, further, faster … World record holder that proves its capabilities all over again every single day No matter what you have in mind, our stationary concrete pumps are more than equal to the task. After all, back in 1977 during the construction of the Frankfurt telecoms tower, it was a Putzmeister concrete pump that surmounted a height difference of 310 metres the first of its world records! As early as the following year, we outperformed ourselves during the construction of the Gotthard road tunnel, when we pumped concrete up a height difference of 340 metres over the impressive...

Good for more than pumping high and pumping far – these pumps are good for almost anything The construction of a high-rise building in Dubai presents different requirements than work on the Yeywa hydro-electric power station in Myanmar (Burma). Construction of a rail link in Tibet at an altitude of 5000 metres is a significantly different proposition to work on the Sutong Bridge in China where Putzmeister pumps had to contend with an extremely inhomogeneous and coarse-grained material. How much concrete needs to be transported, how far in terms of height, distance or both in such cases?...

Expertise gives you a leading edge – not all concrete is equally good Consistent planning for extensive projects For large projects in which heavy concrete needs to be moved very high or very far, you need more than the required delivery performance, you also need an appropriate total solution. Machines, concrete spreaders, accessories and service should all be carefully matched to achieve a good ratio of productivity to cost-effectiveness. Strelasund Bridge, Germany The advantages of rheological investigation: ■■ C alculation of the expected conveying pressure depending on the delivery...

Every country has its own specific concrete Wherever concrete flows, the material that comes into contact with it becomes worn. Abrasion and other damage to components such as concrete hoppers with transfer tube, agitators, pumps and delivery lines are unavoidable. The extent of the wear depends on the composition of the concrete. Concrete differs significantly from country to country and even within a country. The ingenious geometry of Putzmeister concrete pumps was designed for all standard concretes. Delivery and drive cylinders operate in perfect harmony with one another to ensure the...

Above-ground civil engineering – where stationary can also be very flexible Working under high pressure A concrete pump and its accessories are subjected to a very particular kind of stress loading when required to pump concrete upwards. For example, if required to pump concrete up to extreme heights the delivery pressure needs to be correspondingly high. This is needed in part to overcome the height differences and in part because the return flow of concrete develops a counteracting level of energy. This of course necessitates a correspondingly high level of motor or engine power....

Burj Khalifa: world record for this gigantic skyscraper Reliable advances in the construction of the Burj Dubai (Dubai Tower), which (at over 828 m) will, on completion, be the tallest building in the world, were secured by several powerful BSA 14000 SHP D super-high-pressure pumps used in conjunction with MX 28-4 and MX 32-4 stationary placing booms. 165,000 m3 of high-strength concrete was successfully pumped to heights in excess of 606 m (world record) and then poured. Another storey can be concreted every three days – no problem for the potent BSA 14000 stationary pump and its power­...

Underground civil engineering – far-reaching challenge, maximum delivery performance levels Adaptability for tunnel construction One of the difficulties of tunnel construction is the task of incorporating concrete in the cladding or ‘shuttering’ in tunnel walls. This is where Stationary Concrete Pumps from Putzmeister come into their own used in conjunction with rail-guided, hydraulic shuttering placement equipment. This presupposes that these units can be integrated seamlessly within the tunnel diameter, and also calls for flexible tube shears that can cut concreting sections into lengths...

Lainz Tunnel – an elevated form of long-distance delivery The Lainz Tunnel is a 12.8 km rail tunnel in Vienna. This tunnel helps to increase capacity levels for East-West transit. To produce the internal shell in the innercity area, the concrete had to be pumped along a fixed-installation delivery line measuring between 300 and 1400 metres which linked the cement mixer unit on the construction site and the concrete pouring point. The concrete mixture was designed precisely to meet specific structural and pumping requirements and was subject to continuous monitoring from a concrete...

Specialist underground civil engineering – intelligent technology for specific tasks Tunnel walls and slopes secured using the wet-spraying concreting process The wet spraying concreting process is a very cost-effective technology for securing inclined slopes. Small scale construction machinery can also justify its presence on the largest of construction sites. Even where ground conditions are difficult, they are mobile, easily repositioned up and running in a short space of time. For example when building dams, loose rock on the relatively steep mountain slopes to either side has to be...

Mobility associated with pile filling When filling bored piles, it is often the case that many piles have to be installed over a large area. Stationary concrete pumps on a crawler track are ideally suited for this. Additional special equipment such as the lateral pipe guide, a remote control and the integrated 700 litre water tank make the pump the prefect partner when used in conjunction with drilling machines. Putzmeister has 3 of these self-propelled stationary pumps in its product range. With foundation-laying work in the ‘RheinGalerie’ (Rhine Gallery) in Ludwigshafen, a BSA 1412 D RF...
