PRIMARY CRUSHER BOOMS

Pedestal boom systems for primary crushers & grizzlies.

Heavy-duty grizzly arms engineered for jaw, gyratory, and impact primary crushers — designed to clear bridged, slabbed, and oversize feed continuously without taking the crusher offline. Reach and impact energy are matched to your crusher cell and breaker class.

Applications

Jaw crushers

Long-reach arms with high moment arm to clear slabs and bridged rock from the feed mouth — single-operator control from a safe distance.

Gyratory crushers

Articulating grizzly booms with anti-collision limits around the spider and mantle — sized for the spider-cap envelope and uptime-critical primary trains.

Impact & hammer crushers

Compact, fast-swing arms tuned to the high-mass feed of impact crushers, with breaker class matched to impact energy and recycle rates.

Grizzly & live deck

Suspended and cross-beam mounts above the grizzly for continuous scalping intervention — keeps the deck clear and the downstream crushers fed.
