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 , [18] 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.
