Sähkövasara

Sähkövasara, commonly known as an electric hammer or demolition hammer, is a power tool designed for heavy-duty demolition and breaking tasks. It utilizes an electric motor to generate percussive force, driving a chisel or bit into hard materials such as concrete, brick, and asphalt. Unlike a hammer drill, which combines rotation and impact, a sähkövasara focuses solely on powerful hammering action.

The mechanism typically involves a piston driven by the motor, which strikes a striker that then impacts the tool bit. This concentrated force allows for efficient breaking of dense materials where manual labor or lighter power tools would be insufficient. Sähkövasarat are often used in construction, renovation, and roadwork projects for tasks like removing old concrete floors, breaking up foundations, or excavating hard ground.

They come in various sizes and power ratings, from lighter models suitable for smaller demolition jobs to heavy-duty versions used for extensive structural work. Safety precautions are crucial when operating a sähkövasara due to its high power and vibration. This includes wearing appropriate personal protective equipment such as safety glasses, hearing protection, and sturdy gloves. Proper handling techniques are also important to maintain control and prevent injury. The tool's effectiveness lies in its ability to deliver repeated, high-energy blows.
