Hydraulic Breaker Hammer
Hydraulic hammers/breakers are essential pieces of equipment in the
construction equipment industry. They are used in both building and
demolition for the construction industry. For construction, they
can be used to dig holes, breaking up rock, or breaking the dirt to
dig a hole more easily.
When performing demolition, the hammer/breaker can quickly break up
concrete, walls, and foundations to bring down various structures.
Since hammers/breakers can break through hard material easily,
these types of tools are great for the mining industry.
Hammers/breakers are often mounted to skid steers, mini-excavator,
loader backhoes, and large-sized excavators. These tools are great
for building and demolition. The most interesting thing about these
hammers/breakers though is how they work.
