2 BR480RG-1 Mobile Crusher WALK-AROUND Komatsu s newly designed BR480RG-1 enters the market as the most technologically advanced machine available. With excellent crushing power and a production capacity of up to 400 ton/h 441 U.S. ton/h, the Komatsu BR480RG-1 is the optimum choice for your work site. Hopper for easy loading and transport. The hopper is accessible from three sides for material loading High performance impact. The KR1313 maximum-capacity impactor provides high performance with a simple design that facilitates easy maintenance. Komatsu s unique design allows the gap setting to be changed with a simple adjustment in less time than the competition. Grizzly feeder with outstanding muck extraction characteristics. The vibratory grizzly feeder moves the material with an elliptical movement, so that the material is effectively separated and fed evenly into the impactor. HydrauMind hydraulics and all-hydraulic drive system. Fully hydraulic drive system gets you working right away. HydrauMind system supplies the optimal amount of oil through load-sensing and pressurecompensation valves. Outstanding mobility. Hydraulic steering and high travel speed make the crusher easy to relocate. The BR480RG-1 uses the same track undercarriage as Komatsu s hydraulic excavators. 2

FLYWHEEL HORSEPOWER 228 kw rpm OPERATING WEIGHT kg 84,440 lb PRODUCTION CAPACITY up to 400 ton/h up to 441 U.S. ton/h High-speed, large-capacity conveyor belt. A 1200 mm 48" wide belt. The discharge height is 3000 mm 9'10". Komatsu s SAA6D125E-2 engine provides 228 kw rpm for maximum crushing power while keeping exhaust gas, noise, and vibration to a minimum. Water Spray System, including water tank, pump and two sprinkler nozzles is standard. Emergency shut-off buttons are installed on both the left and right sides of the chassis, control panel, and radio remote control (optional). Komatsu s highly productive, innovative technology, environmentally friendly machines built for the 21st century. 3

4 PRODUCTIVITY FEATURES Designed with the operator in mind, the crusher offers the most up-to-date technological advancement to assist with your crushing needs. Equipped with a large capacity impact crusher Equipped with the KR1313 impact crusher, which is one of the largest crushers that can be transported without disassembling. It of course crushes concrete debris, but also fine crushes natural stone, and produces large volumes of high quality product in a single pass. The crusher is equipped with variable speed drive, enabling the production and gradation to be adjusted. Komatsu KR1313 Impact Crusher Gap Adjuster Equipped with an automatic gap adjustment mechanism. The latest automatic gap adjustment mechanism is used. The gap can be changed with one touch, simply by inputting the outlet gap size. Auto The gap can be adjusted automatically, simply by inputting the numerical value for the gap size. Semi-auto The gap can be adjusted to the desired size by operating the buttons. Hopper with outstanding loadability and visibility. The hopper boasts the minimum loading height of any product in its class, and it is designed to be sturdy enough to withstand the weight of large rocks when they are dropped in. Feeder delivers high crushing efficiency. Komatsu s semiauto feeder system is used. If the crusher becomes overloaded, the feeder will adjust the speed automatically so it delivers the highest crushing efficiency for the type and characteristics of each raw material. Grizzly feeder with outstanding muck extraction characteristics. The use of an upward slope feeder and 2-stage grizzly bar, that makes it difficult for the debris to clog up the machinery, delivers outstanding muck removal performance. In addition, the feed volume can be adjusted using the feeder speed dial. A muck chute, which can be switched between mixing and separation of muck is provided as standard equipment. If the optional side conveyor is used along with it, removal of muck from your product can be accomplished easily. Large capacity long belt conveyor. A 1200 mm 48" wide, high speed conveyor for discharge of large volumes quickly is provided. The discharge height is high at 3 m 9.'10". High mobility and transportability. The undercarriage of the Komatsu PC200LC hydraulic excavator is used. It delivers excellent mobility. Also, the use of a crusher case slide mechanism keeps the overall height to within 3.5 m 11'6" while it is being transported.

5 BR480RG-1 MOBILE CRUSHER Achieves both high production capacity and high quality. Through the use of a large model impact crusher and the latest control system, the BR480RG-1 can produce large volumes of cubical final product as a secondary crusher at the rock crushing site and as a primary concrete crusher at the demolition site. Maximum Processing Capacity up to 400 ton/h 441 U.S. ton/h (in the case of 40% muck content) * Production capacity is the sum of crushed volume and muck removal by the Vibratory Grizzly Feeder. It varies with the material to be crushed, their shapes and crushing conditions. Before Crushing (Concrete debris) After Crushing (Concrete debris) Optimum Feed Size 350 x 350 x 350 mm 14" x 14" x 14" (Concrete debris) 150 x 150 x 200 mm 6" x 6" x 8" (Natural stone) * Optimum feed size is the reference size of material which can be fed to the crusher continuously. Maximum Feed Size 750 x 500 x 350 mm 30" x 20" x 14" (Concrete debris) 350 x 350 x 350 mm 14" x 14" x 14" (Natural stone) * Maximum feed size is the maximum size of material which can be crushed if they are fed one-by-one. EASY MAINTENANCE AND SAFETY Outstanding performance and reliability. Highly reliable monitoring system and technology developed for construction equipment are used. In addition, a pre-cleaner and a double element type air cleaner, which are highly effective in preventing dust from getting in the engine, are standard equipment. A large inspection door is also provided on the side of the crusher, enabling a quicker response if trouble should occur, giving this unit outstanding maintenance characteristics. Pedestal Crane used for service and maintenance of the interior crusher wear parts. Easy removal of blow bars. User friendly and comfortable design that is easy on people and the environment. A clean engine that conforms to the North American EPA Tier 2 emission regulations is used. Water spray system with 2 nozzles for spraying water to prevent dust is mounted as standard equipment, and other features such as a full cover on the belt conveyor to keep dust from scattering are included to provide a design that gives consideration to the environment. Easy Operation. All the basic operations are conducted from the ground. The drive system is also operated from a control panel on the top. An optional radio control system that enables remote operation is also available. Safety Emergency shut-off buttons are located on the left and right sides of the chassis, on the control panel and the radio remote control (optional). 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 unusual shut-down on the conveyor belt or optional equipment. A switch is provided to change between crushing, travel and inspection mode. Handrails and safety guards are provided for all sections.
