To move concrete of a give n slump through a pipeline of a particular length and di-ameter at a given rate of flow, a specific line pre s s u r e will be re q u i r ed. In general, the larger the inside diameter of a pipeline, the less pressure required to move a given quantity of concrete through the line at a given ra t e .
t h r ee things—the head diameter, fre q u e n c y, and ampli-tude or “kick.” The larger heads engage more concrete during vibra-tion, and are more effective with large size aggre g a t e s , with low slump, and where a large radius of action is de-s i re d . The frequency and amplitude together establish the

A new method is proposed to estimate pumping pressure based on concrete composition without experimental measurements. Previous studies show that the pumping pressure depends on the interface friction between concrete and the wall of the pumping pipes. This friction is determined by the thickness and the rheology of the boundary layer formed at the interface.Concrete Calculator

Apr 27, 2018· When pouring concrete it is necessary to know how much concrete you need in order to purchase the appropriate amount. Concrete is sold by cubic yards, and one cubic yard of concrete will usually fill a slab measuring 36 inches in length, width and height. You can calculate the amount of concrete you need by employing a mathematical formula.

mounted jib crane. Essentially a jib crane is a boom with a moveable trolley hoist. The trolley hoist moves along the length of the boom and the boom swivels allowing the lifted load to be maneuvered about in a relatively small semi-circular area. The hoists and trolleys of jib cranes are usually slow moving and either manually or radio operated.
Mar 27, 2020· In fact, nozzle spacing and sprayer boom height are two aspects you mustn’t ignore when choosing the size of the spray tip that you need. For starters, nozzle placement—both width between nozzles on the boom and the height of the nozzles above the ground—determines how well your spray coverage theoretically performs based upon the fan ...
Nov 29, 2018· Here’s how you would calculate the load weight of a block of aluminum that is 6 feet long, 3 feet wide, and 4 feet tall: Volume = Length x Width x Height. Volume = 6 feet x 3 feet x 4 feet. Volume = 72 cubic feet. Aluminum weighs 165 pounds per cubic foot (based on the numbers from the table above).
Discharge static head is the height of water above the pump discharge. Total static head is the difference between these two, this is the head that the pump will have to produce to at least get the water up to the high point. Figure 7 Suction, discharge and total static head. The total static head is what we determined in the first part.

Set the boom at the proper height above the ground and spray slowly so the spray wets the ground. If you see streaks as it dries, raise or lower the boom. When the application is even, that boom height is the proper distance to set the boom above your target plants, or ground. If you change nozzles or pressure, check the height again.
To calculate RCC Column size it is required to know the parameters such as factored load on the column, the grade of steel, and the grade of concrete. Put the known value of parameters in the factored load formula .
Using the same calculation method as given before, for Figure 2 we calculate that Load 1 will increase to 5,833 Lbs and Load 2 will drop to 4,167 Lbs. Thus, we can see that the load on crane 1 increases by 1915 lbs or 48.9% going from level to a 60 degree inclination. The increase in load must be accounted for in the lift plan.

Counterweights are mounted on the back of the crane behind the boom to offset the weight of the load. Counterweights are removable for transport, and can be stacked to increase the cranes capacity. Some Cranes even have mobile counterweight like the MAXX-ER which are towed behind the crane like a trailer and connected to the boom via steel cables.
