What is the capacity of a concrete truck?
"capacity of a concrete truckis,the large usual sixe is 9 yards,the smaller are about 3 yards"
Actually over the years the size of mixer drums has increased
You will notice the large the drum the more axles the truck has plus it depends on what make a mixer it is 1) London 2) Jaeger 3) Rex
The early 3 axle trucks with a rex mixer carried 5 cu yards
That increased to 7 cu yards
London and Jaeger drums carried 8 cu yards
On trucks with 3 axles and a tag (4th axle that trails the truck) carried 12 yards or 10m3
The newer 5 axle trucks usually hold 14-16 cu yards
Please understand that 1 m3 = 1.3 cu yards
1 cu yard/27 cu ft of 20 mpa concrete at a 3" slump weights - 3400 lbs
Hope this helps you
The volume of concrete that a concrete truck hold is variable depending on the model of the vehicle. Older ones usually have 6 cubic meters however newer trucks have 8 cubic meter capacity. The volume of concrete a concrete truck hold is proportional to the weight the truck is carrying. In some localities where infrastructure like bridges and roads are not design to carry heavy loads will have to use small volume trucks.
In the delivery from the plant where the concrete is first mixed, the concrete needs to be lightly mixed until it arrives at the recipient's site. If the bowl on the back of the truck were not revolving, the concrete would settle out due to vibrations as the truck travelled the highways. It would need to be re-mixed before use. And if the truck stops because of some accident, the concrete has to be removed…
Concrete pumping trucks can be hired through concrete suppliers as well as large truck rental establishments in most major cities. The strength of the pumping truck may vary from truck to truck, so it is important to verify with the rental supplier just how strong of a pumping truck one requires, to ensure that the job can be completed successfully.
