Synopsis on pneumatic hammer



pneumatic hammer

A pneumatic hammer is more commonly referred to as a jackhammer or power hammer. They are of the same family and do roughly the same thing on differing scales. If you are driving through a big city then you have most likely seen them used by city workers as they break up a road for some reason unknown to you. A pneumatic hammer is typically connected to an air compressor that feeds into the device. Once you apply pressure to the triggers the blade begins to move at a very rapid RPM up and down through the shaft. This generates enough thrust to break apart most materials. The pneumatic hammer can be found in many sizes and speeds and some can have their maximum speed adjusted to your needs. The article that follows will go over several things that a pneumatic hammer is used for.

Road Construction

A pneumatic hammer is one of the main tools of workmen that are contracted the job of road repair. They often use the pneumatic hammer to chisel away the road to create an even surface in which to lay asphalt. They are also used to break through the road to the sewers below in order to create new manholes or access points. What many people do not realize is that roads are made from layers upon layers of asphalt, stone, concrete and other materials. This makes a road very difficult to break through without using a pneumatic hammer.

Rock Removal

When you are digging trenches for use as ponds, swimming pools or house foundations you may come into contact with a large boulder. Most rocks you come across are easily removed but some cannot even be removed by using a backhoe. These large boulders hinder projects often. A pneumatic hammer may be called in and used to chip away at the boulder. The pneumatic hammer will break off large chunks of the boulder that will manageable.

Concrete Walls

Concrete wall removal is difficult and made more so when enforced with steel. If you could knock it over it still will be impossible to move. The solution to this problem is to use the pneumatic hammer to break it into chunks that can be removed with a bulldozer or other such heavy machinery. A pneumatic hammer was used to break away the Berlin Wall. Using a pneumatic hammer for this particular problem requires one that is portable. You will also need to be able to be elevated in order to reach what has to be removed. Smaller pneumatic hammers are used to install concrete hardware without having the user exert any strength.

Building Construction and Demolition

Tools that are traditionally used to rip down a home or aspects of it include sledgehammers, axes, pry bar and other pieces of equipment. Large pneumatic hammers can be used to break apart the foundation of the building. This is also the case for walls. A small pneumatic hammer can be used to install large nails, bolt and the like through metal beams, duct and conduit.

Pneumatic Hammer Working

A pneumatic hammer, also known as air hammer or power hammer uses compressed air to carve or chip away at stone, metal and other materials. It is a tool generally used to shape or smooth a surface area, to dig holes or cut through a surface. An air hammer, which is a replacement for the traditional hammer and chisel, is a handy tool that is very valuable for its speed which at times may lack a bit of precision in the final result. Pneumatic hammers are generally attached by a tube or hose to a large tank that pumps up air and thus making the pistons move.


Material Required:

  • Pneumatic cylinder
  • solenoid valve
  • air compressor
  • hammer
  • shafts
  • metallic based
  • clamps


Automatic hammer can be used in industries where metal sheets are being prepared. It will save the time and the cost of the man power and consumer less human energy. It is widely used in industries for producing the plain metal sheets mechanism.

Money saving

Time Saving

Efficiency increasing

More output in less time


After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working is working with very ease and efficient way.The hammer is working in a right manner by hitting the objects accurately with pressure.

Box Shifting Machinde


Box shifting is our major project.
This device is operated by Motor. We are controlling this machine with ac motor . we know in these days time & Money is very important. In production centers there are more need of above works. So if we take all machine for all work then a large investment is required to purchased them and obviously space also required. So to keep this in mind we made this project. We can do all works in one machine. Hence we can save space and money as well as time also.

We rotate a motor with 220 Volt. This rotation is transmitted to the machining head by a shaft and the required operation is carried out. First of all we rotate pinion. This pinion is mechanically attached with crown and a round plate. Crown is directly connected with a drill bit holder and round Plate changes the rotation energy into horizontal movement with required mechanism. With this shaft one side a hex-saw is attached and other side a shaper is attached. At end of shaft we can connect more tools.

  4. More output in less time


Base on the application of the device, I would say that it is very useful for small industrials, Carpenters,

regenrative braking system

In this project we will generate electricity from brake applied in vehicle.

project will generate electricity and  will protect from slipage of vehicle also.

Tyre will be used for opposite forces.

in this project there will be a cucle tyre will be fixed on rod. tyre will move using a motor. when brakes applied then brake tyre will touch with cycle tyre. electricty of motor during this duration will be stopped .

when opposite brake tyre touch with cycle tyre then brake tyre will rotate shaft of dynamo

so electricity will generate
