View Patent ↗A concrete boom hose is provided with a first end that is connected to the outermost end of a series of concrete pipes and a second end through which the flowing concrete exits. The second end is provided with an inner diameter that is smaller than the inner diameter of the first end that is connected to the concrete pipe.
1. A boom hose for use in a concrete pumping system of the type utilizing a concrete pump to provide a flow of concrete through a series of pipe sections to a hose for distribution of the concrete into a form or other area, said boom hose comprising:
a length of flexible tubing having a first end coupled to the outer end of a delivery pipe, said first end having a first inner diameter and
a second end from which the concrete flows, said second end having a second inner diameter with said second inner diameter being smaller than said first inner diameter,
said flexible tubing having a uniform and continuous taper along its entire length from said first inner diameter to said second inner diameter.
2. The boom hose defined in claim 1 wherein said second inner diameter is substantially eighty percent (80%) of said first inner diameter.
3. The boom hose defined in claim 1 wherein said boom hose has a length in excess of ten feet (10′).
4. The boom hose defined in claim 1 wherein said first inner diameter is substantially five inches and said second inner diameter is substantially four inches.
5. A boom hose for use in a concrete pumping system of the type utilizing a concrete pump to provide a flow of concrete through a series of concrete pipe sections to a hose for distribution of the concrete into a form or other area, said boom hose comprising:
a length of flexible tubing having a first end coupled to the outer end of a concrete pipe, said first end having a first inner diameter and
a second end from which the concrete flows, said second end having a second inner diameter with said second inner diameter being substantially eighty percent (80%) of said first inner diameter,
said flexible tubing having a uniform and continuous taper along its entire length from said first inner diameter to said second inner diameter.
