A breaker is a powerful percussion hammer fitted to an excavator for demolishing hard (rock or concrete) structures. Breakers are often referred to as “hammers”, “peckers”, “hoe rams” or “hoe rammers”. These terms are popular and commonly used amongst construction/demolition workers.

How does an electric concrete breaker work?
How Do Concrete Breakers Work? This is the same way in which pneumatic concrete breakers work now. Electric or petrol models use the same theory – however, they power a motor which moves the piston. This then creates a small amount of air pressure which will move the bit up and down.
What is a breaker used for in construction?
Breakers, also known as a hammers or hoe rams, are powerful percussion tools used for breaking up concrete or rock. They can be fitted to excavators and are powered by auxiliary hydraulic systems. They are similar in function and operation to hand-held pneumatic drills.
Can a hammer drill break up concrete?
Hammer drills do not have a chiseling function and can be used to drill into a variety of materials. Demolition hammers can break, chip and chisel concrete, but they can’t drill because there is no rotation of the bit.
Is jackhammer a drill?
Jackhammers are a type of percussive drill. They pound away at a surface to break it into smaller pieces.

What kind of oil do you use on concrete breakers?
Breaker & Hammer Air-Oil is a fully synthetic lubricant with excellent lubricating, rust-preventing and de-icing properties, especially developed for TEX pneumatic breakers and hammers, as well as DIP and DOP pumps, for a smooth continuous operation under extreme conditions.
Is a jackhammer hydraulic or pneumatic?
Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete.
Why does a breaker keep tripping?
If your circuit breaker keeps tripping, it’s usually a sign of something wrong with the circuit. There could be a short circuit in one of the appliances or somewhere in the wiring. There could be a ground fault causing the breaker to keep tripping. There could be a circuit overload.
What causes breaker to trip?
A circuit breaker will usually trip when there is an electrical fault that could cause damage to the circuit. This is usually an excess of current, a power surge or a faulty component.
How does a circuit breaker operate?
Internally, circuit breakers are basically made up of pairs of metallic contacts, both fixed and moving, in addition to an operating coil. As the moving contacts separate, the circuit inside the CB (circuit breaker) opens, interrupting the flow of current and protecting the system from further damage.
