The jackhammer is a versatile
drill that may be powered hydraulically, electrically, or pneumatically. It is
used for drilling rocks, breaking pavement, and other work that needs violent
hammering. It functions like a chisel and hammer by poking with the bit, and
not a rotary motion.
Jackhammers are drills that
are generally used for the demolishing of concrete pavement, roads, and rocks.
Jackhammers are also extensively used in the mining industry, excavation works,
and construction projects. There are several categories of jack hammers, all
designed to increase the blow and speed of work. The main types are pneumatic
that performs by the high pressure of air from an air compressor. Hydraulic
jackhammers operate by hydraulic energy from some fluid. The third kind is the
electric jackhammers that function by electric power. This machine is suitable
for minor maintenance and construction tasks. It does not need much energy to
operate and will be operative as soon as it is connected to an electrical
socket. The jackhammers are extremely useful for the preparation of building
foundations. The jackhammer is considered to be one of the most widespread
robust tools that are being utilized in construction engineering and other
disciplines of engineering. The jackhammer tools and jackhammer bits should be
carefully selected according to the type of work.
The jackhammers are fairly
tiring to control considering the heavy tasks being performed, for which
professional skills are essential. Generally, the jackhammer bits are extremely
hot during operation, for which special care should be taken. The remaining
parts are also warm, and the operator should be careful during the work. The
jackhammer is not practical for operation on steep slopes and walls, since it
is dependent on the inertia of the body mass, to force the bit into the
material. Also, for the tool to be efficient, gravity is necessary to bring the
machine back into contact, after every blow. The jackhammer is normally used by
bending over the tool to operate it. A method being practiced for horizontal
operation of the jackhammer is that one man operates the jackhammer, while
another supports the hammer on his arms, or the shoulders. The combined weight
of the two men is used to force the tool bit into the work.
The jackhammer is used for
drilling and the tool bit revolves at a high speed due to which excessive
vibrations are produced. Therefore, it is essential that the requisite safety
precautions must be observed during the operation of a jackhammer. The
