Descripción
Power trowel is a construction machine used to impart a smooth surface finish on freshly poured concrete slabs. This machine consists of one rotor which rotate parallel with the slab surface. Discs or multi-bladed attachments are spun against the still soft concrete surface by the rotors, thereby effectively smoothing out any blemishes or high spots.
When concrete slabs have been thrown, the surface of the concrete is uneven and rough. Most construction specifications require an even slab surface which requires the concrete to be smoothed before it sets and cures. A screed is used to smooth the surface on small slabs, sidewalks, and walkways. A screed is a flat wooden, steel, or aluminum beam that is drawn across the concrete surface to smooth out any high and rough spots. On larger slabs, this method is impractical, and the power trowel comes into its own as the preferred method of surface finishing.

How a Power Trowel Works
Basic Mechanism
A power trowel works by rotating its blades at high speed over the concrete surface. This action smooths and compacts the concrete, creating a dense and level finish.
Different Functions of Blades
Different blades are used for different stages of the finishing process. Float blades are used initially to level the surface, while finish blades give the concrete its final, smooth appearance.
Types of Power Trowels
Walk-Behind Power Trowels
Walk-behind power trowels are ideal for smaller projects or areas where maneuverability is crucial. They require the operator to walk behind the machine, guiding it over the surface.
Ride-On Power Trowels
For larger projects, ride-on power trowels are the go-to option. These machines allow the operator to sit or stand on the trowel, covering more ground efficiently and with less physical exertion.
Key Components of a Power Trowel
Blades
The blades are the heart of the power trowel, responsible for smoothing and finishing the concrete. They come in different types for different stages of the finishing process.
Motor
The engine powers the trowel, and its efficiency directly impacts the performance of the machine. Common engines are either gasoline or electric.
Mango
The handle allows the operator to control the trowel. In walk-behind models, it’s crucial for maneuvering, while in ride-on models, it houses the controls.
Choosing the Right Power Trowel
Factores a tener en cuenta
When selecting a power trowel, consider the size of your project, the type of concrete finish desired, and your budget. Other factors include the power source (gasoline vs. electric) and the ease of maintenance.
Popular Brands
Brands like Wacker Neuson, PME, Allen Engineering, and Multiquip are renowned for their reliable and high-performance power trowels. Choosing a reputable brand ensures better support and spare parts availability.
Using a Power Trowel
Preparation Before Use
Before using a power trowel, ensure that the concrete is at the right stage of curing. It should be firm enough to support the machine but still pliable for finishing.
Operating Techniques
Operate the power trowel by guiding it smoothly over the concrete surface. Start with float blades to level the surface, then switch to finish blades for the final pass. Maintain a steady pace to avoid uneven finishes.
Power Trowels vs. Hand Tools
Comparative Analysis
While hand tools are suitable for small, intricate jobs, power trowels are unbeatable for large surfaces. They provide a superior finish and save a significant amount of time and effort.
When to Use Each
Use hand tools for touch-ups and small areas where precision is key. For large slabs and floors, a power trowel is the best choice for a smooth and even finish.
The concrete should be firm enough to support the machine but still pliable for finishing.
Regular maintenance should be performed after every use, with more thorough checks monthly or as recommended by the manufacturer.
Yes, walk-behind power trowels are ideal for smaller projects and areas requiring more maneuverability.
Common issues include engine troubles, blade wear, and handle malfunctions.
While they can be a significant investment, the efficiency and quality of finish they provide often justify the cost.
