Utilized heavily in the construction industry, an excavating jack hammer is a handheld tool that is used to break up surfaces made up of hard materials, such as asphalt and concrete. This device operates through the use of a piston striking a specialized chisel which is then employed to chip away at the target material.
In the last decade of the 19th century, King Charles Brady breathed life into a revolutionary invention that has since become integral to excavation and construction – the jack hammer. Originally intended for mining usage, its use quickly spread into construction, with its air-powered model eventually supplanted by its electric counterpart.
The versatile excavating jack hammer is a godsend when it comes to demolishing concrete pathways, driveways, and walls. Its effectiveness doesn’t go unrecognized either – it’s also quite successful at removing asphalt from roads and parking lots.
When using an excavating jack hammer, precautionary steps must always be taken to keep everyone safe. Protective eyewear and ear gear are a must, along with a clear mindedness and alertness while operating the tool – eliminating any possibility of being fatigued or under the influence of drugs or alcohol.
All electric jackhammers should be plugged into a correctly grounded source of power; never a long cord. Previous to doing any maintenance or repair work on the device, be certain to eliminate the current from the energy source.
Get acquainted with the jack hammer by giving it gentle tappings to begin with; then, steadily apply pressure as you break through the material. In no case should one sway the jack hammer in a sledge-like motion.
When tackling hard material, a chisel attachment may be necessary to properly break it up. Make sure to pick the right-sized one for the job – don’t let a chisel that is too big overwhelm the material you are trying to handle!
When it comes to working on surfaces with rebar or any other kind of metallic reinforcement, be sure to employ a chisel with a carbide tip. These tools, specifically crafted for hard materials, guarantee an intact metal reinforcement and protect against any potential damage.
The jack hammer must be disconnected from its power source and unplugged once you’re done using it. It should be stowed away in an appropriate place where it won’t sustain any harm and won’t present a danger to anyone in the vicinity.
