Jack hammer india

Types of jack hammer india

A jack hammer is a large tool that uses a steel chisel to break concrete, pavement, and rocks. Also called a demolition hammer, this equipment is quite popular in India, especially in construction industries. There are three main types of jackhammers used widely in India. They include electric, pneumatic, and petrol jackhammers.

Electric jack hammers

Electric jack hammers operate using an electric motor. They are either corded or cordless. Corded models use electrical power while battery-powered jack hammers use rechargeable batteries.

Electric jack hammers possess several advantages. They are easy to operate and generate little noise. Also, they can be used in both outdoor and indoor settings. Indoors, they work perfectly since they create less debris and seem less bulky.

Pneumatic jack hammers

Pneumatic jack hammers work by forcing compressed air through valves. The high-pressure air produces rapid hammering motions, allowing the tool to break tough materials. These jackhammers are mainly used for heavy-duty projects like breaking up concrete, rocks, paving, and asphalt because they generate enormous power. Even with their high power, they weigh less than most electric hammer drills.

Pneumatic hammers have several advantages. They tend to be more powerful compared to electric jack hammers, especially for heavy-duty tasks. In addition, they are often lighter and more durable. The tools can be easily carried and used in different construction works, such as drilling blast holes in rocks for necessary blasting and in trench excavating for water lines or electrical wiring.

Petrol jack hammers

Petrol jack hammers are strong and very portable. They are powered by air, but mostly by automotive gasoline engines. Because of these features, they are used where electricity cannot be found.

These judgement hammers function best in mining and quarrying operations. They are usually used to drill holes in rocks, underground mines, and in both open-cut and underground quarrying. Petrol jack hammers are very convenient for blasting operations because they allow easy drilling of blast holes in tough and inaccessible rock formations.

Specifications and maintenance of jack hammers

The jack hammer parts play a very big role in the performance of the hammer. Some popular brands of jack hammers have decided to make specific parts universal, but most parts tend to differ depending on the hammer model. Therefore, buyers should ensure that they keep the following specifications in mind.

Hammer energy

This is usually measured in joules per blow. Higher joules means more power and more efficiency when tackling hard materials.

Blow rate

It states the blows per minute. Usually, higher BPM enables faster work since the tool will be hammering more times within a given minute.

Chisel or bit types

These are jack hammer parts that provide desired performance depending on the type of material to be broken. Jack hammer chisels come in various shapes, such as pointed for prying and flat for splitting heavy materials.

Housing material

This refers to the outer part of the hammer. It can either be composite or steel. It affects weight, noise levels, and durability of the device.

Handles

Jack hopper handles are either anti-vibration or non-anti. Anti-vibration handles tend to reduce the effect on the operator's hands.

The maintenance of jack hammers

• Regular service: Some manufacturers recommend servicing the hammer after a given number of operating hours. This service can be done by a professional, or if one is mechanically inclined, it can be done by oneself.
• Replace worn parts: A jack hammer used for hard jobs wears out, especially if it is overused. Any worn part should be changed. Worn parts affect performance and can damage the other parts.
• Lubricate: Users should always ensure that the hammer is well lubricated. Lack of lubrication hastens the rate at which the worn parts wear out. Most jack hammers use grease, while some use oil. Always follow the manufacturer's guidelines.
• Clean air filters: In pneumatic hammers, air filters and other pneumatic components accumulate dust and other particles from the air. This debris clogs air filters and pneumatic tubes. Clogged filters affect pneumatic jack hammers' performance and can even cause damage.

The average jack hammer price in India

Demolition hammers have different prices depending on their type, how powerful they are, the brand, and where they are purchased. The average jack hammer price in India is around 15,000 rupees. Electric jack hammers tend to be cheaper, while pneumatic and petrol hammers are more expensive because they are meant for heavy-duty work.

Scenarios where jack hammers can be used

Jack hammers break hard materials by repeatedly striking them with a chisel. Therefore, they are ideal for drilling, excavating, or ripping out concrete walls, floors, and pavements. The strong vibrations and high-pitched noises should be expected when using jack hammers for such projects. Other machinery, such as pneumatic compressors or gas-powered engines, might be present in these scenarios. This is because the compressors and engines power the Pneumatic and Petrol jackhammers respectively.

Mining and quarrying

Jack hammers are very useful in mining and quarrying industries. They are mainly used to break rocks, excavate trenches, and drill blast holes in the quest for minerals and other valuable resources. In these situations, pneumatic and petrol hammers are mostly preferred. They provide enough power required to tackle dense and tough rocks.

Road construction and maintenance

Jack hammers play a crucial role in road-building or refurbishing pavement and other roadworks like installing underground utilities such as water, electricity, or sewage lines. Electric jackhammers are mainly used during the refurbishment of old pavements. Jack hammers have also been effective in the repair of pipelines buried beneath roads and other infrastructure.

Demolition works

As the name suggests, jack hammers are widely used in demolition works. They break concrete walls, floors, and pavements. This makes them a common sight in the refurbishment of residential and commercial buildings. Since refurbishment requires breaking interior and exterior walls and pavements, interior paint sprayers are used for this work.

Tiling

Jackhammers come in handy when removing tiled surfaces from walls and pavements. They are able to break and efficiently and effectively remove old tiles, especially on large-scale pavements.

How to choose the appropriate jack hammer

• Power source: Buyers should be clear on where they will use the hammer. If the hammer is to be used where power outlets cannot be accessed, petrol jackhammers should be used because they do not require electricity. Pneumatic hammers also require pneumatic compressors, so they also do not have to be used indoors. Electric jackhammers can be used indoors, especially where power outlets are available, because they tend to produce the least noise and are the least portable.
• Jack hammer weight: Pneumatic and petrol jack hammers are largely powerful and tend to be heavy. They are not as portable as the lighter ones. The power tools are ideally used for large-scale construction projects that require breaking tough materials like rocks and thick concrete. More electric corded jack hammers are lighter and can easily be transported. They are suited for small projects.
• Impact rate: Most petrol and pneumatic jackhammers have a higher blows per minute. They are best used for large construction work that requires breaking large rocks and huge and thick concrete slabs. Corded jack hammers have a lower BPM, which is better for smaller jobs, making them more efficient.
• Chisel locking mechanisms: There are three main locking mechanisms for chisels. They are the cylindrical type, wedge-type, and tool-free locking mechanisms. Tool-free locks are the best because they do not require an extra tool to lock or unlock. Cylindrical and wedge types have their own locking tools, which can be misplaced, bringing inconveniences. The cylindrical and wedge types also tend to lock strongly, making them ideal for large projects that require going on for long hours.
• Vibration dampening mechanism: Jack hammers have one major disadvantage: they have strong vibrations that sometimes irritate the operator after a long time. This is why most modern hammers are equipped with anti-vibration systems, making them more comfortable to use for longer periods. Corded electric jack hammers are better because they possess advanced anti-vibration systems. It is vital to consider the number of working hours before purchasing the hammer. If it is going to be used for a long time, manufacturers with good anti-vibration systems should be selected.
