Applications demanding long reach and high breaking power such as gyratory crushers in mines and quarries and grizzlies in mines require a Rammer L940 boom.

These Rammer L940 booms, like Rammer S- and Rammer M-series, feature a triangular design.

The boom pedestal is designed round for even stress distribution into the foundation.

Rockbreakers suit up to the Rammer 4099, with on operating weight of over 3 tonnes, and are capable of efficiently breaking large boulders of several cubic meters.
