Q. What is a jack hammer used for?

Answer

A jack hammer is mostly used to fragment materials that resemble rocks. They were initially employed in mining operations to split apart rocks. They were then employed to aid in the construction of tunnels since they could easily break up rocks that conventional digging implements would find challenging to remove. They are primarily employed today to dislodge concrete and asphalt off roads.The impact of the hammering movement produces percussion, which causes the stiff rock to vibrate and break into smaller pieces. Except for a strong person, it is impracticable to use a full-sized mobile jackhammer against buildings and steep slopes since the user would be required to maintain the weight of instrument while also pushing the tool firmly against the job after each blow. A two-man team is a method that seasoned workers have devised to get around the problem of gravity. One guy works the hammer while the other helps by supporting him by carrying the hammer on either his shoulders or in his arms. The bit is pushed into the workface by both people using their combined weight.
