Atlas Copco and Ingersoll Rand were two important drill companies in Europe and America respectively, each holding patents and dominating the industry.
From this mining and railway tunnelling expanded. The word "jackhammer" is used in North American English and Australia , while "pneumatic drill" is used colloquially elsewhere in the English speaking world , although strictly speaking a "pneumatic drill" refers to a pneumatically driven jackhammer.
In Britain , electromechanical versions are colloquially known as "Kangos". A full-sized portable jackhammer is impractical for use against walls and steep slopes, except by a very strong person, as the user would have to both support the weight of the tool, and push the tool back against the work after each blow.
A technique developed by experienced workers is a two-man team to overcome this obstacle of gravity: one operates the hammer and the second assists by holding the hammer either on his shoulders or cradled in his arms.
Both use their combined weight to push the bit into the workface. This method is commonly referred to as horizontal jackhammering.
Another method is overhead jackhammering, requiring strength conditioning and endurance to hold a smaller jackhammer, called a rivet buster, over one's head.
To make overhead work safer, a platform can be used. One such platform is a positioner—actuator—manipulator PAM.
This unit takes all the weight and vibration from the user. A pneumatic jackhammer, also known as a pneumatic drill or pneumatic hammer ,  is a jackhammer that uses compressed air as the power source.
The air supply usually comes from a portable air compressor driven by a diesel engine. Reciprocating compressors were formerly used.
The unit comprised a reciprocating compressor driven, through a centrifugal clutch , by a diesel engine.
The engine's governor provided only two speeds:. Modern versions use rotary compressors and have more sophisticated variable governors.
The unit is usually mounted on a trailer and sometimes includes an electrical generator to supply lights or electric power tools.
Additionally, some users of pneumatic jackhammers may use a pneumatic lubricator which is placed in series with the air hose powering the air hammer.
This increases the life and performance of the jackhammer. An electropneumatic hammer is often called a rotary hammer, because it has an electric motor, which rotates a crank.
The hammer has two pistons — a drive piston and a free flight piston. The crank moves the drive piston back and forth in the same cylinder as the flight piston.
The drive piston never touches the flight piston. Instead the drive piston compresses air in the cylinder, which then propels the flight piston against a striker, which contacts the drill bit.
They require an external power source, but do not require a compressor. Although in the past these tools did not have the power of an air or pneumatic hammer, this is changing with newer brushless-motor tools coming close to the power of a pneumatic tool and in some cases even matching it.
Electric powered tools are useful for locations where access to a compressor is limited or impractical, such as inside a building, in a crowded construction site, or in a remote location and it is not uncommon under earth moving equipment or tool.
The connection end size is also related to the breaking energy of the tool. See hammer drills for more on electropneumatic hammering.
A hydraulic jackhammer, generally much larger than portable ones, may be fitted to mechanical excavators or backhoes and is widely used for roadwork, quarrying and general demolition or construction groundwork.
Such tools can also be used against vertical walls or ceilings for that matter , since the vehicles involved are massive enough and powerful enough to exert the forces involved without needing the help of gravity in operating the tool.
Pneumatic or hydraulic tools are particularly likely to be used in mines where there is an explosion risk such as underground coal mines , since they lack any high-power electrical circuitry that might cause a triggering spark.
Hydraulic breakers usually use a hydraulic motor driving a sealed pneumatic hammer system, as a hydraulic hammer would develop a low strike speed and transfer unacceptable shock loads to the pump system.
Advances in technology have allowed for portable hydraulic breakers. The jackhammer is connected with hydraulic hoses to a portable hydraulic powerpack: either a petrol or diesel engine driving a hydraulic pump; or a mini-excavator or skid-steer via a power take-off driveshaft to the machine's hydraulic system.
Hydraulic power sources are more efficient than air compressors, making the kit smaller, cheaper or more powerful than a comparable pneumatic version.
Chisels may be resharpened in a shop or with an angle grinder with grinding disc. After resharpening, they must then be heat treated to restore the integrity of the steel before use.
Although some pneumatic jackhammers now have a silencer around the barrel of the tool, the primary noise source comes from the chisel striking the object being removed.
Use has been linked to Raynaud syndrome ; in particular, prolonged exposure to the pronounced vibration conducted by the tool can lead to a secondary form of the syndrome known as vibration white finger.
Applying athletic tape is not very effective in preventing white finger but seems to help alleviate some of its discomfort. Pneumatic drill usage can also lead to a predisposition for development of carpal tunnel syndrome.
Some manufacturers of electro-pneumatic tools now offer vibration reduction systems to reduce the vibration felt by the operator.
Other manufacturers such as Makita , DeWalt and Bosch also offer electric tools with vibration dampening. Using a jackhammer to break up concrete pavement may expose the operator to hazardous dust containing respirable crystalline silica.
