Cemco’s Model 340 Portable Concrete Paving Package (http://cemcoinc.com/wp-content/uploads/2010/09/Cemco_340_Portable_PavingPackage.pdf) aims to save concrete producers money in 2 big ways.
First, and most obvious, Cemco’s solution saves money every single time you need to do a setup or take down. The plant, auxiliary silo, and central mixer are all self-erecting with the pull of a handle. The whole setup with feeder conveyors and everything can be setup in ½ day with two men and some basic tools. Everything is pre-wired and pre-plumbed, and all electrical and hydraulic connections are of the quick connect type and are clearly labeled.
Second, and more discrete, Cemco’s equipment saves money on the big maintenance. Our Central Mix drum is essentially the shaft in a large ball bearing; therefore, there is not a track and rollers like every other mixer. This means that the load is distributed around our drum instead of focused on the two drive points like other drums. With a more even load distribution, we do not run into drum cracking problems. We do not have severe maintenance requirements on our drum rotation system. The user simply needs to grease the bearing periodically and change the oil on our motor gear boxes.
