The newly designed Komatsu BR380JG-1 mobile
crusher looks simple but is very powerful. The
upgraded Komatsu designed crusher offers
maximum production capacity.
The KCJ4222 large-capacity jaw crusher provides
maximum crushing capacity in this class along with
easy maintenance. In addition, Komatsu’s locking
cylinder mechanism allows you to change the discharge
clearance with a simple one-touch adjustment and also
facilitates the removal of clogged foreign material from
the discharge side.
Newly designed vibrating
grizzly feeder The vibrating grizzly
feeder moves the material elliptically,
so the material can be effectively
separated and fed evenly into the jaw.

Hydraulic steering and high-travel speed make the
machine easy to relocate. The BR380JG-1 uses the same
track undercarriage as Komatsu’s hydraulic excavators.
Hydraulic conveyor lifter in the up position ensures
adequate ground clearance even on rough ground. The mobile
crusher uses a new interlock system that controls the travel, to
prevent the conveyor from being dragged or colliding with the
ground, depending on the conveyor’s position.
