2 The New World Standard SCX15002 Take A Close Look. The SCX15002 Sets New Standards of Higher Crane Productivity And Profitability More Than Ever. As the second unit, Hitachi and Suitoo have created the New World Standard Crane of 150t class achine. Developed along the concept thees of "siple, refined and reliable", the SCX15002 offers new levels of safety, operability, durability and ease of aintenance. Advanced clutchless ultiple wetdisk brake is well designed, and ensures continuous heavyduty operation. Multiple wetdisk brake Dru Reduction gear unit Hydraulic otor The winch uses a ultiple wetdisk brake, and a forcedoil cooling syste is designed to sustain brake perforance even in continuous heavyduty operations, such as haer grabing. This brake syste is designed to provide reliability while requiring no aintenance. Also, a newly developed echanis is used on this brake design to reduce drag resistance and it realizes a sooth frictionoff between discs while a highviscosity hydraulic oil is used as standard, contributing to longer lift of hydraulic pups and otors. Powerful winch dru with bigger line pull. The SCX15002 is really a versatile achine, and certainly perfors not only liftcrane/luffing towercrane works but also duty cycle works under clashell, haer grab and dragline applications with bigger line pull of 196kN < 20t > as axiu with 26 dia. cable. In addition, by eploying a speciallytailored power increase control, the engine always axiizes its output under any load condition in whole range of engine rp. Optional third dru. A third dru is optionally available under the sae specifications as that of two ain operating drus, and it accordingly enables to efficiently perfor heavy duty works under an 196kN < 20t > line pull. New negative brake syste uch reduces operator fatigue and enhances safety. With a new negative brake of springapplied/power hydraulicallyreleased type Pressure applying dynaic hydraulic pressure reduction valve for its release control, an effective braking can be done under an extree light foot pedaling, and it accordingly results in greatly reducing operator fatigue, especially during winch freefall operation under duty cycle applications. Further, the use of negative brake syste aintains a high level of brake safety even if a hydraulic pressure drop in the circuit happens. Brake pedal An aluinuake oil cooler. For not only corrosion resistance but also high cooling efficiency, an aluinuake oil cooler is provided in front of engine radiator. 2

4 A high operation ease with speciallytailored EPC syste. Thanks to unique EPC syste, an easypreciseinute control of engine rp and pup discharge fro in. thru ax. is really possible at the sae tie by siply padaling the foot throttle which links "EPC" controller electrically. Linkage echanis Cab large sliding door with a swinglink design. For easy entry and exit to and fro the cab, and sooth door opening and closing, a swinglink type large sliding door is well designed. And, a swinglink door design certainly eliinates a troublesoe occurrence like a gathering the ud into rail groove, railrust and so on unlike railslide door. Slidable control station and operator seat. To set ost of suitable operator position, both right and lefthand control stations are designed to siultaneously slide 60 back and forth together with operator seat, and operator seat is able to slide 80 independently too. Optional airconditioner of outsideairintake type. For good airconditioning wih fresh air, an outsideairintake type airconditioner is optionally available. A good swing & boo hoisting/lowering speed control design. Boo hoist dru rotation speed can be freely controlled thru knob dialing independently for ore precise cobined operation of hook and boo otions. In addition, ax. swing speed can be freely controlled thru knob dialing too, and, as an exaple, it realizes a precise cobined operation under higher hook hoisting and lower swing speed in high lift work. Further, ore soother swing can be realized in any kinds operations and works too because, as a ain reason, a variable displaceent axial piston pup is designed in swing circuit. Universal joystick control station. An universal joystick control station is provided for a good, easy and cofortable operation for two ain operating drus, boo hoist dru and swing. For travel otion, two archair control levers are provided behind righthand universal joystick control lever for operator cofort. Siplified and easytoread panel. A large LCD graphic dispaly panel of Load Moent Indicator is provided with a reflectionless design on display panel. And, the switches, eters/gauges and controllers are functionally grouped for operator control convenience. 4

5 The New World Standard SCX15002 JobProven Controllability and Operator Cofort A newly designed operator's cab. In consideration of operator cofort, a new operator s cab uch iproves the visibility thru front and both side windows of the cab with siplified layout of control station with two universal joystick control levers. In addition, a reinforced light greentinted safety glass is adopted in front window to protect operator fro ultraviolet rays and airborne debris. 5

6 The New World Standard SCX15002 Pays a keen attention to safety, transport and environent too. Safety Autoatic dru pawl locking device. On boo hoist dru, it is designed to autoatically lock and release dru pawl when control lever just returns to neutral position, and just actuates. Newlydesigned Load Moent Indicator. An easytoread LCD graphic display panel is well designed and a reflectionless display panel is provided on a new Load Moent Indicator (LMI) with setting ease of viewing angle. In addition, no zeropoint adjustent, and data input thru interface counterindication/essage on display panel are available for easier and certain setting of operating conditions and LMI functions. Of course, "present lifting load", "rated load", "load ratio", "working radius", "boo angle", "engine rp" and so on are indicated on the LMI dispaly panel. Further, displayed picture and enu selection can be easily set up by panel switch in accordance with operation situation and condition. LMI autoatically sets frontend att. erection ode with letter essage. In the range out of crane working area, the LMI display panel autoatically indicates "Now, out of crane working range" with a rigging instruction, and it is available to lift frontend att. off ground without the influence of M/L safety functions, and, after frontend att. is lifted over the range of crane working area, LMI safety function gets back autoatically for safe erection work. Boo speed slowdown function. This function is available just before autoatic stopping at both upper and lower side liits of boo angle to prevent a shock even though control lever is still at hoisting/lowering position. This function is also available when overloading. Optional lifting height indication function. For ore safe lifting work, especially in blind condition, it is optionally available to indicate the lifting height above ground or depth below ground on display panel of LMI. 6

7 Fool proof shutoff syste. To insure safety when the operator leaves the cab, a ain hydraulic shutoff switch is located in the cab exit to deactivate and lock the hydraulic syste. Swing/travel alars. These alars alert work crew around the acine when swinging and/or traveling to keep clear for safety. Mobility Transportability Counterweight with horizontallyspit design. It is able to load boo extension(s) onto counterweight when transport. And, the reversible stack is possible to reduce the tie for disassebling/assebling works. An assebling ease of crawler side fraes. Thanks to "hookon design" with hydraulic reoval jointpins, crawler side fraes can be easily assebled and disassebled on and fro carbody frae, and it accordingly result in a tie saving task. Environent The engine eets current EU Eission Regulations for OffRoad Diesel EngineStage 3, and Japanese Eission Standard for Diesel Construction EquipentStage 3, and the SCX15002 clears low noise levels as defined by Ministry of Land, Infrastructure and Transport of Japan under the new noise easuring ethods regulated by ISO. 7
