2 M OBILE C RUSHER WALK-AROUND The newly designed Komatsu mobile crusher looks simple but is very powerful. The upgraded Komatsu designed crusher offers unsurpassed crushing capacity of ton/h ( US ton/h. High-performance jaw. The KCJ4222 large-capacity jaw crusher guarantees maximum 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 onetouch adjustment and also facilitates the removal of clogged foreign material from the discharge side. Radio remote control provided as standard equipment Function: Travel Left/Right/ Forward/Reverse Crusher On/Off Feeder On/Off Emergency Shut off Horn 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. 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 pressure-compensated valves. Optional equipment can be connected at the hydraulic outlets on the chassis. Large-capacity hopper. The 2500 mm 8'2" x 3700 mm 12'2" hopper is accessible from three sides for material loading. Hydraulic conveyor lifter in the up position ensures adequate ground clearance, and safe driving even on rough ground. 2

The discharge height is 2800 mm 9'2". PRODUCTION CAPACITY ton/h U.S. ton/h Rotating lamps. Red lamp lights to indicate travel mode, excessive load on crusher or unusual conditions. Amber lamp lights when unit is in radio remote control mode. Sprinkler nozzles and a connector are standard at the jaw entry and the main conveyor discharge. Komatsu s SAA6D102E-2 engine provides 134 kw rpm for superior crushing power while keeping exhaust gas, noise, and vibration to a minimum. Outstanding mobility. Hydraulic steering and high-travel speed makes the machine easy to relocate. The uses the same track undercarriage as Komatsu s hydraulic excavators. Photos may include optional equipment. Emergency shut-off buttons are installed on both the left and right sides of the chassis, on the control panel, and on the remote control. Komatsu s highly productive, innovative technology, environmentally friendly machines built for the 21st century. 3

4 M OBILE C RUSHER PRODUCTIVITY FEATURES Equipped with the largest jaw crusher in this class, the offers next generation performance. Lock cylinder Toggle plate Fixed link New Komatsu Jaw Crusher, largest in its class. The large-capacity jaw crusher, KCJ4222, is another successful example of Komatsu s development efforts. Crushing efficiency is improved dramatically with the installation of a load-presetting semiautomatic feeder system and the increase of the crusher rotation speed. Fully automatic discharge setting adjustment system. The jaw crusher is equipped with an automatic discharge setting adjustment system that makes it easy to change the preset aperture of the discharge port. Even as both of the jaw plates or either one wear, you can adjust the discharge clearance with a simple one-touch operation (adjustable within several minutes) with this automatic system. On the monitor panel, you can choose one of the three adjustment modes (Patent pending). The first hydraulic crusher protection mechanism in the world. Jaw crushers typically protect themselves by bending toggle plates when they are clogged or jammed with metal debris. The KCJ4222 protects itself by allowing the locking cylinders to fully open the discharge port, which makes it easy to remove clogged foreign material from the crusher (Patent pending). Large production capacity. Komatsu s large-capacity jaw crusher and the most advanced control systems have considerably increased its output capacity, making it easy to manage large workloads. KCJ4222 Jaw Feed opening: 1065 mm x 550 mm 42" x 22" Mode A: Input a desired value for the discharge setting. Mode B: Increase or decrease the current discharge setting. Mode C: Push down the manual switch to increase or decrease the present discharge setting. Fully Automatic Discharge Setting Adjustment System Production Capacity Maximum production capacity (with a muck content of 30%). Unit: ton/h U.S. ton/h Material Natural stone Concrete debris Crusher Discharge Setting (open side) 50 mm 80 mm 120 mm 150 mm 2.0" 3.1" 4.7" 5.9" Note: Hydraulic Crusher Protection Mechanism The production capacity is the sum of the quantity of the material crushed by the crusher and the quantity of the material that passed through the grizzly bar. It depends on the type and properties of the material and the working condition. 4

5 M OBILE C RUSHER EASY MAINTENANCE AND SAFETY High-speed, large-capacity conveyor belt. The high discharge height of 2800 mm 9'2" makes it easy to configure a system with stockpile conveyors and screens. With its width of 1050 mm 42" and a belt speed of 120 m 394 ft/min., the belt conveyor has a high volume capacity. In addition, the conveyor reverse mode is provided to facilitate the removal of jammed foreign matter. High mobility. The conveyor elevation system secures a high minimum ground clearance, which realizes the crusher s outstanding maneuverability at any crushing site. In addition, improved location of the guide handle makes it much easier to operate the conveyor lifter. Minimum ground clearance When traveling: 300 mm 12" When crushing: 100/200 mm 3.9"/7.9" Maximum Reliability and Minimal Maintenance. In addition to the spacious clearance of 530 mm 21" between the jaw crusher and the conveyor belt, the crusher s bottom area is concealed with covers. This construction prevents re-bar from being caught by the crusher s member structure. Wide openings on the side frames also ensure easy access to the space below the crusher to remove clogged foreign material. Comfortable Design. The engine is Tier 2, EPA, EU and Japan emissions certified with a horse power of 134 kw 180 HP. The mobile crusher generates less noise and its engine is environmentally friendly. To prevent dust generation, sprinkler nozzles are provided as a standard attachment at the top of the jaw crusher and at the head of the main conveyor. Easy Operation. All the switches necessary for operation are located on the main control panel, making it easier for the operator standing on the ground to reach and safely control the operation. As the control system is equipped with the onetouch start feature, all you have to do is push the start switch. This simple operation will sequentially start the operation of the magnetic separator, belt conveyor, jaw crusher and feeder. The multi-function monitor displays the status of all the components in real time. With this monitor, you can easily identify the origin of a problem. Safety. Emergency shut-off buttons are located on the left and right sides of the chassis, on the control panel, and in the radio remote control (optional). A rotating lamp flashes when there is a malfunction on the monitor display (for example, when overheating has occurred) and the operator is also alerted by a buzzer in the event of an abnormal shut-down on the conveyor belt or optional equipment. A switch is provided to change between crushing and travel modes. Handrails and safety guards are provided for all sections.
