Anyone who has ever mixed concrete using a wheel barrow and a garden hoe appreciates the convenience of a concrete mixer. If you will be doing more than one project, or the project is large, purchasing a used concrete mixer is the best way to go. Concrete mixers come in different sizes and types. Choosing the right one for the job will make it much easier.
Types of Concrete Mixers
Every construction site has its own unique set of challenges. There is a mixer for almost every type of situation that one will encounter. A truck concrete mixer is what most people are familiar with. This is a big unit that is mounted on a heavy duty truck. They keep the concrete in motion until they get to the site so that it does not start to harden. Self-loading concrete mixers allow the dry and wet material to be added directly to the truck, rather than being premixed. Rough terrain concrete mixers are mounted on a four wheel drive truck that can get to almost any location. They allow concrete to be discharged from every side of the vehicle, making them ideal for remote locations, such as villages. The volumetric concrete mixer is a truck where all components are stored in different compartments. A meter controls the mix. This type of truck delivers fresh concrete when needed.
Smaller Portable Units
If these mixers are too large for your needs, many smaller units are available that are more practical for the homeowner. Hand-fed site concrete mixers this type of unit is simply a rotating barrel. The worker feeds the materials in the correct proportions to the mixer, then tips it forward when the concrete is delivered. Portable concrete mixers come in side-dump and end-dump models. Portable mixers come in many different speeds and horsepower levels. They are often powered by petrol or diesel.
Purchasing a secondhand concrete mixer can be more cost effective than renting one, particularly if you will be using it on a regular basis. When purchasing a used concrete mixer, it is important to ask the seller how many hours of use the motor has on it. Concrete mixer motors take a lot of abuse and must often pull heave loads for long time periods. Getting one with low usage hours is the best bargain.
