With worldwide experience and up-to-date technology, Schwing has designed highly efficient and low-maintenance pumps ideal for long-term use under the most severe conditions. The innovative concrete boom pumps came into being in order to make the tedious process of carrying concrete for heights easy, says VG Sakthikumar, Wholetime Director Operations, Schwing Stetter India. Excerpts of the interview.

Brief us about the advantages of using boom pumps.
The boom pumps are a different breed of concrete pumps; unlike other stationary and line pumps where the pipelines need to be laid well before pumping, the boom pump does not require this exercise. It has an assembly of pipelines with R, Z or R-Z folds which enable its 360o rotating capacity. Schwing Stetter India manufactures two types of boom pumps; truck-mounted and separate placing boom pumps. Each of these has their own applications. The separate placing booms are usually opted for high-rise building projects whereas the boom pumps can be used for all applications and also has a reputation for providing faster completion.

What should a client look forward while opting for a boom pump?
The most economical construction machine is the one that can be used continuously. Therefore, it should be rugged, reliable and above all, suitable for universal applications. Schwing Stetter has designed its boom placers which are superior to all comparable placing booms in all working ranges. Separate placing booms, which are used in combination with stationary concrete pumps, have established themselves as the ideal concrete distribution system in high-rise construction and other largescale structures.

What are the benefits a customer get by using Schwing boom pumps?
The benefits of Schwing separate placing booms are many, from increased concrete placement speed to having a tower crane free to handle other necessary lifting and reduced labour requirements. Schwing Stetter India manufactures separate placing booms ranging the radius from 25 m to 35 m. These separate placing booms are equipped with a floor-climbing mechanism to meet the increasing demand in high-rise construction.

What are the benefits of truck-mounted pumps?
At construction sites around the world, truck-mounted concrete pumps are widely used. On account of their high utilisation, these machines are an integral part of the vehicle fleets of uncounted pump services. These pumps also set a new standard in occupational safety.

How user-friendly is the Schwing range of concrete pumps?
All the pumps manufactured by Schwing Stetter are remote controlled and are extremely user-friendly. These pumps have very low operative maintenance cost and are easy to operate. There are multiple greasing points in every pump to allow smooth operation of the pump. The hydraulic circuit offered by Schwing Stetter is an open circuit as compared to the closed circuit offered by others. The open circuit curbs the hydraulic oil temperature from rising and suitable for dusty environments, hence cuts the costly maintenance.

Schwing Stetter pumps are backed by an adept service team and ample service centres across the country to attend to any problems in the pump. Patented German rock valve technology and excellent after-sales support has helped Schwing Stetter be leaders in India.
