Small projects may only need a mini plant capable of producing approximately 30 cubic meters an hour for as little as $15,000. Meanwhile, larger scale production plants that produce 1000 cubic meters an hour could cost as much as $1 Million each hour! At the core of any concrete batching plant cost is its own structure: its plant itself.

The 39M Concrete Pump will pour up to 180 cubic yards of concrete per hour. The concrete will be mixed all throughout its use, allowing for a smooth, efficient build. This is worth noting as the longer the reach of a pump, the longer the concrete will have to travel to reach its destination. Any stagnant time span will cause the concrete to harden.
