Types and Uses of Jackhammers

A jackhammer is an electric or pneumatic tool that seamlessly combines a hammer and a chisel. It was created by William Mcreavy, who later sold Charles Brady King the patent. Although some hand-held jackhammers also use electric motors, compressed air is typically used to power them. Larger jackhammers, like those mounted on construction equipment rigs, are typically hydraulically powered. Typically, these tools are used to dislodge concrete, pavement, and rock.

A jackhammer works by pushing an internal hammer up and down. To start the cycle, the hammer is first lowered to strike the chisel, and then it is raised again to return to its starting position. The amount of force used on the jackhammer will determine how effective it is. It is not regarded as earth moving equipment, along with its accessories, because it is typically used in construction projects to break hard surfaces or rocks.

What is a Jackhammer?

A jackhammer, as the name implies, is a tool used to hammer apart hard materials like rock, concrete, asphalt, and the like. Although it can be applied to even harder materials like metal or softer materials like wood, doing so is neither advised nor nearly as effective. The hammer mechanism inside the tool is either powered by compressed air (pneumatic), electromechanical force, or hydraulics, depending on the design and size of the tool.

Although rock is very durable, it is also very rigid, which makes it an excellent material for a jackhammer to break up. They are occasionally referred to as demolishing hammers, a term primarily used in the UK. A smaller version of a jackhammer is a demolition hammer. By examining the handle, you can tell a jackhammer apart from a demolition hammer. The smaller demolition hammers have an L- or D-shaped handle, while jackhammers have a T-shaped handle.

How Do Jackhammers Operate?

The jackhammer’s operating principle is based on repeatedly applying a percussive force to the material that needs to be broken up. Although the method of applying the percussive force can vary depending on the jackhammer’s power source, the basic idea remains the same. Along with tools that need to be disassembled, we also have tools that require bonding. Here is more information on fastening tools.

The device’s end is fitted with a jackhammer bit, typically a sizable chisel, which is moved back and forth to produce a percussive impact. Stone and other rigid, strong materials can be broken up with a few quick impacts. The substance is divided into manageable pieces for later removal.

The strength of the person using the handheld jackhammer determines how powerful it can be. For instance, using a jackhammer along steep slopes or on vertical surfaces like walls is not practical due to the jackhammer’s weight, which makes it a challenge to lift and control at the same time. In this situation, rig-mounted jackhammers are useful.


Between 1857 and 1871, the tunnel connecting the cities of Modan, France, and Bardonecchia, Italy, was built using the first jackhammers (easel). Germaine Sommeye, an engineer, created these devices. Later, Georg Liner created the first portable perforator, which shared many characteristics with the modern jackhammer.

The first hammers entered our country in the 1930s of the 20th century. Most people are probably familiar with Alexey Stakhanov, a well-known Soviet miner who is famous for exceeding the coal mining plan by extracting 102 tonnes of coal instead of the planned 7 instead of doing so. After all, this event was greatly influenced by new machinery, particularly strong jackhammers. A monument honoring Stakhanov that features a miner carrying a jackhammer on his shoulder was erected in the Luhansk region after his passing.

A jackhammer is a tool used primarily for breaking up solid objects like frozen ground, asphalt, rocks, and concrete. Think of this device’s construction as being like that of a straightforward pneumatic hammer. This device uses compressed air to power its piston impact mechanism. A specialized air-distribution system transforms compressed air energy into mechanical energy, ensuring the drummer’s activity. Although there is no mechanism for the bit to rotate, the jackhammer’s general structure is very similar to that of the perforator. This tool’s primary purpose is to deliver a strong blow. The active component is a peak, which can take on various shapes.

What Are the Types of Jackhammers?

There are two types of jackhammers: handheld and rig mounted. Although they are still quite large and powerful, the smaller jackhammers are held in the hand as their name suggests. Larger and more powerful rig-mounted jackhammers are typically used in situations where a handheld jackhammer is impractical.

There are three different jackhammer types within the two categories. The performance of all three types is essentially the same. The way they are powered differs.

Pneumatic Jackhammer

The pneumatic jackhammer also referred to as a pneumatic hammer or drill, is powered by compressed air. An air compressor for this kind of jackhammer is powered by an engine, typically a diesel one. In earlier models, a centrifugal clutch was engaged by a reciprocating compressor. This indicated that the jackhammer was either inactive or operating at its highest speed when it was powered.

Modern pneumatic designs use a rotary compressor as their power source. They are typically rig-mounted and quite big. Modern designs frequently include an electrical generator as part of their power supply. The pneumatic lubricator that is connected to the air hose makes the more recent versions of reciprocating compressors more durable even though they function in essentially the same ways as the older models.

Electric Jackhammer

These are portable jackhammers, which are typically much smaller than pneumatic models. The jackhammer’s chisel component is moved by a crank, which is rotated by an electric motor, as the name suggests. There are two pistons, one for drive and the other for free flight.

The device is powered by a crank that reciprocates a piston inside a single cylinder. The free-flight piston is never actually touched by the piston itself. Instead, the flight piston is propelled to strike the striker, which then contracts with the bit by the compressed air that comes from the drive piston.

In most cases, electric jackhammers are plugged into an outlet. They can be as light as 12 pounds and are typically small. They are typically used for demolition work inside a structure because they are small enough to be handled easily. This kind of jackhammer is quite adaptable, but due to its small size, it takes longer than other kinds of jackhammers to break apart hard materials over a large area.

Hydraulic Jackhammer

This kind is typically mounted on a rig because it is so large. They frequently ride on backhoes or excavators. They are occasionally used for street maintenance but are more frequently seen in sizable mining, building, and demolition projects. A hydraulic system is smaller and more effective than a pneumatic system, despite being more substantial and heavier. Additionally, it is easier to construct and stronger as a result.
