Pumping concrete through a separate placing boom has replaced crane-and-bucket methods on many high-rise construction jobs. Mounted on a pedestal, the boom supports placing line and discharge hose, eliminating the time-consuming work of moving line and hose during each pour. This setup isn't always the most efficient way to use a separate placing boom, however. One way to get maximum use is with booms that can be mounted on either a truck or a separate pedestal. A quick-disconnect assembly allows them to be quickly detached and either flown from one location to another on the same job or back to the truck for use on a different job.
