A portable device designed to combine cement, aggregate (such as sand or gravel), and water to produce concrete. These mixers are characterized by their ability to be hitched to a vehicle for transportation, enabling concrete production at various job sites where pre-mixed concrete delivery might be impractical or costly. For example, a contractor working on a remote fencing project might employ this type of mixer to create concrete footings for fence posts directly on-site.
The utilization of a mobile concrete production unit offers several advantages. It allows for on-demand concrete creation, reducing waste and ensuring material freshness. This is particularly beneficial for small to medium-sized projects, repairs, and locations with limited access. Historically, manual mixing was the only option for small concrete needs; the advent of the portable mixer has significantly improved efficiency and reduced labor requirements in such scenarios.
