Scaling is removal of loose material from the tunnel roof and walls to prevent accidents by falling rocks.

Rammer has always been at the forefront of hammer development, and the 999 scaler is just a part of the next phase in hammer development for special applications, such as scaling.

Scaling is an extremely tough job for the hammer, and only a specialized scaling hammer should be used.
