Pumping Up A Record-Setting Project

摘要

In early April 2008, a Putzmeister BSA 14000 SHP-D pump reached yet another world record on the Burj Dubai in the United Arab Emirates with an extraordinary concrete conveying height of 1,988 feet (606 meters). Unimix, the concrete supplier and pumping service for the project, first set its own record with its BSA 14000 SHP-D in May 2007 for reaching a conveying height of 1,483 feet (452 meters) for level 126 of the Burj Dubai, and then in November 2007 it broke a world record by conveying concrete to a height of 1,971 feet (601 meters) for Burj Dubai. The total number of floors at completion for Burj Dubai will not be revealed until the entire project is complete in 2008, but it is already the world's tallest building.
