Jack hammers
To make a rough hole in walls, ceilings, foundations, remove asphalt, loosen soil and cut metal, special electric hand tools are often used – jackhammers. The main function of this tool is a powerful blow, due to which the destruction of hard rock occurs. With this tool, you can quickly and effectively demolish a wall or partition, make a hole or remove old stone tiles, asphalt or other high-strength coating.
Depending on the way the engine operates and the impact energy is obtained, a distinction is made between gasoline, electric and pneumatic breakers. Pneumatic and gasoline hammers are used in places where there is no access to electricity. Pneumatic hammers are also powerful. However, the operation of gasoline and pneumatic hammers is not always convenient, therefore, in conditions of large-scale construction, as a rule, electric jackhammers are used, connecting them, if necessary, to a portable generator.
