Concrete placers are large, motorized machines with conveyors used to transport and place uncured concrete. Hand-held concrete placers/levelers are small tools used for touch-ups. Mechanical placers are used for large projects like roads, while small drum mixers are used for smaller structures.
Concrete placers are heavy, large, motorized construction machines equipped with conveyors. They can be chutes that transport concrete from a concrete mixer to a narrow formed area or very wide dump trucks with an average width of about 60 m (18.6 ft) that transport uncured concrete from a concrete mixer and place it efficiently in a large area.
The hand tools that are advertised and sold as concrete placers are more properly concrete levelers which are blades, average about 19 inches (48.3 cm) wide and are usually constructed of aluminum or steel, with a long wooden handle. or fiberglass attached. The blade at the working end of these hand-handled concrete placers/levelers looks like an ice scraper or squeegee.
The large mechanical, conveyor-equipped concrete placers resemble very low road bridges. These machines are designed to place and level concrete mix across the width of a road using a combined conveyor and tip-up dump system powered by concrete mixer trucks or vehicles capable of transporting the mix without allowing it to cure. These tape type positioners are most commonly used for paving roads, highways, airport runways, culverts and large parking lots. Conveyor-type concrete placers are tracked or pneumatically mounted and are capable of maneuvering autonomously. After the concrete has been poured, spread and leveled by a mechanical placer, workers will use hand-held concrete placers/levelers or other concrete tools to make any minor touch-ups.
Concrete placers can also be small drum mixers that can be mounted between the blade arms of a front loader and maneuvered into areas too confined for a conveyor-type placer. The agitator is motor driven and the mixing drum can be tilted via the machine’s hydraulic system allowing the mix to be poured where desired and then distributed quickly and effectively with a spreader fitted below the agitator. These types of mechanical concrete positioners would be used to lay concrete driveways, patios or floors for small to medium sized structures.
The Hand Concrete Positioner or Leveler can be used in a number of applications such as placing, spreading, leveling and smoothing uncured or liquefied mix. These small concrete positioners/levelers are useful for everything from small touch-up jobs on large paving projects to working concrete in a localized area. Other types of concrete hand tools include trowels, rakes, grinders, trowels, and brushes.
