RBR500JG-1A
Komatsu’s SA6D125E-2 engineprovides 228 kW 310 HP @ 1950 rpm for maximum crushing power while keepingemissions, noise, and vibration to a minimum.
HydrauMind hydraulics and all-hydraulic drive. Fully hydraulic drive system gets you working right away. HydrauMind system provides the optimal amount of oil through load-sensing and pressure-compensated valves. Optional equipment can be connected through hydraulic outlets in the chassis.

With unsurpassed crushing power and aprocessing capacity of 85 to 460 U.S. ton/h, the BR500JG-1A is the optimum choice for your work site.
Outstanding mobility.Hydraulic steering and high travel speed make the crusher easy to relocate. The BR500JG-1A uses the same track undercarriage as the PC400 Hydraulic Excavator.
Vibratory Grizzly Feeder. By vibrating the materials at an acceleratedspeed, the material is separated and fed evenly into the jaw.

Emergency shut-off buttons are provided on the left and right sides of the chassis, the control panel, and radio remote control.
Hydraulic conveyor lifter at the high positionensures adequate ground clearance when driving. Thelower position allows for more rebar space.
Sprinkler nozzle and aconnector are standardfor a sprinkler pump.
High-speed large-capacity conveyor belt. A 900 mm 2'11" wide, 12 mm 0.5" thick belt moves at 95 m 312' per minute. Discharge height is 2800 mm 9'2".

Rotating lamp flashes to indicate travel mode,shutdown, and high pressure malfunction.
Fixed hopper for easy loading and transport.The overall height of the hopper (which can be loaded from three sides) is just 3790 mm 12'5".
The K-Series Jaw offers highperformance with a simple design thatfacilitates maintenance. Designed by Komatsu,an adjustment of the jaw discharge settingrequires less time than the competition.
Vibratory Grizzly Feeder
By vibrating the materials to be crushed on a two-stage
grizzly bar, the Vibratory Grizzly Feeder removes muck
before it can enter the crusher. This improves crushing
efficiency and extends the service life of the crusher
jaw plates.
● Feeder operating speed is controlled by a flow control
valve so the volume going into the crusher can be regu-
lated according to the type, size, and hardness of the
material.
● The Grizzly Bar is a removable cassette-type, so replace-
ment and build-up welding can be accomplished quickly.
Superb Maneuverability
Superior performance, in the form of 25 degree climbing
power and a maximum traveling speed of 3 km/h 1.9 mph,
is achieved through the powerful 228 kW 310 HP Komatsu
SA6D125E-2 engine. The primary belt conveyor, which is
raised/lowered by hydraulic cylinder, allows for a ground
clearance of 370 mm 1'3" during traveling. Superior
operating power is maintained on uneven ground.
A Crusher with Superior Starting Torque
The BR500JG-1A is equipped with a hydraulic drive system
that stands up to rain, dust, and vibration, providing reliability,
durability, and easy maintenance. Two powerful hydraulic
motors mounted on the left and right sides of the crusher
frame (an industry first) provide balance for high-efficiency
crushing and exceptional durability. In the event of an
emergency, the powerful drive torque allows for easy restart
with rock still inside the crusher. A manual reverse button is
also provided in the event that it should be necessary to
eliminate bridging or remove foreign objects.
Easy Operation
Anyone can easily start and stop the crusher, reverse
its direction, turn the grizzly feeder on and off, turn the belt
conveyor on and off, and in an emergency, stop all functions
with the push of a button.
Dial operation allows the feed speed of the grizzly feeder
to be changed to realize the optimal speed for the material
being fed in.
Malfunction Warning System (Caution Light)
The caution light goes on in the following cases to warn
of a malfunction:
● Overheating
● Belt conveyor malfunction—the crusher and feeder
stop at the same time
● The belt conveyor is not lifted when the machine
starts to move

MAINTENANCE
EASYMAINTENANCE
Operation● Emergency stop units are provided in a total of four places: on the left and right sides
of the machine, on the control panel, and on the radio control panel, offering quick and
easy access.
● A rotating lamp flashes when there is a malfunction on the monitor display (for example,
when overheating occurs) and the operator is also alerted by a buzzer in the event of
an abnormal shutdown of the conveyor belt or optional equipment.
● Handrails and guards are provided for all sections.
A Crusher with Superior Ease of Maintenance
● Jaw discharge setting can be
adjusted easily even by one person
using Komatsu’s proprietary easy-
adjust mechanism. Adjustment time
has been significantly reduced.
Since settings can be modified
easily, depending upon site con-
ditions or the intended use of
the crushed material, operation
efficiency is greatly enhanced.
● Two hydraulic motors are mounted
on the main body of the crusher, allowing V-belt tension to be adjusted easily (the
need for belt tension adjustment during disassembly and transport is avoided).
● The cheek plate is divided in two to facilitate replacement and to lower costs.
Low Noise, Low Vibration, and Safe Design
Employment of a low-noise engine, sound suppression materials, and a low-speed
high-torque hydraulic motor provides low-noise and vibration levels of less than 65 dB (VL).
A sprinkler is also provided to protect against dust.
*Depends on the hardness of materials
Designed by Komatsu, the K-Series Jaw is portableand practical. An adjustment of the jaw dischargesetting requires less time than the competition.
EasyMaintenance● Each part is lubricated by a
central lubrication system.
● A double air element and a precleaner are standardequipment.
● Employment of a flat floorallows engine room inspectionand grizzly bar cleaning to beeasily accomplished.
● The grizzly bar is a cassette-type, and can be easilyremoved, which makes its replacement and weld padding easy.
● A toolbox provided with a grease gun is standardequipment.
