Description

5.1

Application

A wide selection of easily interchangeable tools is available for drilling holes from 
12 to 125 mm suitable for breaking, chiseling, digging, puddling, hammering, 
ramming and deburring. The machine is suited for processing natural as well as 
synthetic stone and asphalt and any type of masonry and concrete.

5.2

Functionality

Principle

The machine is a demolition hammer with a pneumatic percussion system as 
well as an additional drilling function.
It is driven by a maintenance-free three-phase AC motor.
A frequency converter converts the generated DC voltage to required three-
phase AC current.

"Chiseling" operating mode

The rotary movement of the three-phase AC motor is converted into a stroke 
movement via a transmission and a crank gear while in "Chiseling" operating 
mode.
The piston is moved forwards and backwards by the crank gear, this compresses 
the air (forward movement) or generates a partial vacuum (backward move-
ment). Due to change in pressure the percussion piston is moved forward and 
backwards (air cushion percussion system) and hits the tool.
While in "Chiseling" operating mode, the drill drive is uncoupled via the safety 
clutch and the tool holder bushing is fixed in place to prevent turning in the tool 
holder.

"Hammer drilling" operating mode

While in "Hammer drilling" operating mode, the rotational movement of the motor 
is transferred to the drive shaft of the drill drive via a clutch. The drive shaft uses 
gear wheels to turn the tool holder bushing in the tool holder.
