Before you can construct something new, you often must demolish the old. Rented breakers allow contractors to break up old concrete and asphalt for removal. They can break up concrete driveways, sidewalks, parking lots, footings, foundations, walls and other concrete or blacktopped surfaces.
When considering which breaker is best to rent for your application, keep these six factors in mind:
- Power source. You can rent demolition breakers that run on electricity, compressed air, gasoline or hydraulic power. For more information, see Power Sources of Rented Breakers Vary.
- Weight. A common way to classify breakers is by their weight class, which for handheld breakers can range from 20 to 70 pounds. Most breakers that you would rent for horizontal demolition weigh 25 pounds or less. A 35- to 40-pound breaker falls in the mid-duty range. The 60- to 70-pound breakers work well for breaking pavement and larger jobs.
- Blows per minute (BPM). Smaller breakers tend to offer more blows per minute than larger breakers do.
- Horizontal vs. vertical breakers. The design and weight of heavy, two-handled breakers in a T-configuration obligate you to hold them upright for vertical breaking of concrete floors or slabs. Lightweight, one-handled breakers allow you to hold them horizontally to break through walls or vertically for demolishing flat slabs of concrete or pavement. Horizontal breakers work well when you have a large area of concrete to break up, while vertical breakers typically deliver more blows per minute than horizontal breakers can deliver.
- Points, chisels and tools. Most breakers can accept a wide variety of tools — sometimes called either bits or tool steel — to suit different applications. Types of tools you can rent for a breaker include moil points for random breaking of concrete, chisels for exact concrete breaks or for scaling a clean edge, and spades for use on rocky dirt and hard clay.
- Safety features. For safety, look for features in a breaker that dampen vibration, reduce sound and suppress dust.
