Rammer Boom XL940R

With a long reach, 360° rotation and high breaking power, the Rammer Boom XL940R is ideal for demanding applications such as gyratory crushers in mining and quarry applications, and grizzlies in mining.

The Rammer XL940R Boom can be operated directly by the valve levers or by using a Rammer radio control. An upgrade is available to incorporate TRS BoomSafe® controls, enabling remote operation via the plant network and in-built collision prevention with programmable automated movements such as park and deploy.

Boom swing with slew ring enables wider coverage, easier service access and constant swing torque.
