Concrete line pumps are a portable, towable, small concrete pump used for many concrete pumping applications.
The concrete pumping process starts with the discharge of concrete from a ready mix truck into a hopper on the trailer pump.
The larger diameter hoses 3, 4, and 5 inch are typically used for pumping concrete.
The towable concrete pump does all the work of getting the concrete where you need it, you just have to level it.
The volume of concrete pumped through a line pump varies depending on the size of the line pump and the diameter of the concrete pump pipe, most can pump 30 cubic yards per hour but some outputs can be as high as 150 cubic yards per hour.
A cubic yard is an Imperial / U.S. customary (non-SI non-metric) unit of volume, used in the United States, Canada, and the UK. It is defined as the volume of a cube with sides of 1 yard (3 feet, 36 inches, 0.9144 metres) in length.
1 cubic yard.

Tokyo Electric Power is struggling to block a crack in a pit that is leaking highly radioactive water into the ocean at its Fukushima Daiichi nuclear plant.
Staff discovered the 20cm-wide crack in a shaft storing supply cables close to reactor No 2. Tepco is injecting an absorbent polymer, sawdust and newspapers into the pit in its latest effort to block the leaking water, after Saturday’s attempts to plug the leak using concrete failed.
If Tepco is successful this time, concrete will be poured over the polymer to make it permanent, a government official said.
