Product Description Specifications and Technical DataGB-74-1800 Underground Mining Mobile Rock BreakerGB-125-2800 is a medium-sized underground crusher suitable for 3×3 meter mine tunnels. This underground crusher is used for secondary crushing during underground mining to prevent ore blocks from being too large to load and transport. GB-125-2800 has been improved and upgraded based on the original underground crusher, with further improved safety level and smoother operation and maintenance.High crushing performance:Better overall stability and larger crushing hammers can improve ore crushing capacity and work efficiency. The new improved working mechanism is easier to adjust positioning and stable control. With the unique working mechanism, GB-125-2800 can take operations to a new level.Rugged Design:The heavy-duty frame is designed to cope with harsh underground environments. It is made of the best Q460C steel plate, robot-automatic welding, and integrated processing technology to ensure reliability and durability.Comfortable operation:GB-125-2800 is equipped with two working positions. Sitting upright is convenient for operators to position the working mechanism and crush the ore. Sitting sideways can better drive the equipment in the underground tunnel. The telescopic outrigger structure is adopted on both sides of the machine body, which works stably and reliably. The 4 outrigger cylinders can be controlled separately and adjusted smoothly.Intelligent control system:The electromechanical and hydraulic integrated control system monitors all equipment parameters in real time to ensure human and machine safety. The cab can quickly view various information and provide fault diagnosis.Main parametersHammer impact energy2800JHammer strike frequency3 5 0~ 65 0 bpmHammer working oil pressure1 47 ~ 1 66 barDrill rod diameter1 25 mmForward and reverse speed (with Cumins F4.5 CS4168 )1st gear4.4 km/h2nd gear7 km/h3rd gear1 1 km/hWorking mechanism and cab dataWorking arm left and right swing angle± 30°Maximum working height of hammer4 265 mmThe longest working distance of hammer4051 mmMaximum ground clearance when drill rod is vertical2 300 mmCab typeClosedMachine dataOperating Weight1 70 00 kgDimensions8 207 mm × 1 740 mm × 2 320 mmTurning Radius5 127 mm/ 3022 mmMinimum ground clearance2 50 mmGradeability14° (25%)* Operating weight depends on options selectedWorking conditions and restrictionsOperating ambient temperature-15 ° C ~ +50°CStandard operating altitude rangeAdopt Cumins F4.5 engine, from -1500m to +2000m, no power loss at 25oCStandards according to which the equipment is designedJB/T5503-2004 Vertical Grab Backhoe LoaderJB 8518 Safety requirements for underground loadersGB25518 Safety requirements for underground loadersQ/XY 008 Stone Crusher Enterprise StandardPowertraindiesel engineCumins F4.5CS4168Rated Power125 kW @ 2 2 00 rpmRated torque6 70 Nm @ 1 3 00 rpmNumber of cylindersInline 4 cylinderExhaust volume4. 5 LCooling systemWater-cooled engine, radiator uses engine-driven cooling fanCombustion Principle4-stroke direct injection engineIntake air filterDry air filtration, pre-filtration + two-stage filtrationElectrical System24 VEmission standardsNational FourExhaust systemDOC + DPFAverage fuel consumption(at 50% load )1 4.3 L/hFuel tank capacity180LTorque ConverterManufacturing PlantDANAmodelC270Transmission GearboxManufacturing PlantDANAmodelR32000typeElectronically controlled gearbox, three gears forward and reverseAxlesFront axleSpring brake hydraulic releaseRigid axleWJ 2 (normally closed)Limited slip differentialRear axleSpring brake hydraulic releaseRear axle swing, swing angle ±8°WJ 2 (normally closed)Standard differentialTireTire sizeSolid tire 12.00-24Tire brandDomestic famous tiresHydraulic systemHydraulic oil radiatorTransmission oil radiatorMaximum heat dissipation can meet the ambient temperature of ≤50oCConnector StandardJIC StandardHose StandardGB3683Hydraulic oil tank capacity180LLiquid level sight glass1 pcHydraulic filterLiming HydraulicsFiltration accuracy20μmFiltration systemTwo-stage filtrationHydraulic linesA large number of bending machines form seamless galvanized steel in one step to replace traditional hydraulic hoses.

The seat is in a double working position, which is convenient for the operator to work and drive. It is equipped with a three-point safety belt and the seat can be adjusted forward and backward.The GB-125-2800 cab roof adopts a reinforced design to protect the operator. The cab is strong enough to prevent falling rocks and rollover to protect the operator's safety; the cab is equipped witha high-strength protective grille to prevent flying rocks from injuring workers; and is equipped with operating lights to provide a clearer view for operators during stone crushing operations; and the operator's fatigue is reduced by increasing legroom and improving the pedal position.CabEnclosed cabHigh strength protective grilleDry powder fire extinguisherFully hydraulic pilot proportional control handleWashable cab floor to reduce dustThree-point entry system for the cabAll power circuit breakers of the whole machine are disconnected from the power switchShock-absorbing seatsCab dashboardThe icon-based panel makes it easier for operators to identify alarm switch information, allowing them to spend more time focusing on the road and working operations.Industrial Standard Control SystemWarning and alarm systems Sound and light alarm promptDashboard Icon-based dashboard 7-inch color display Fully functional knob and button switch control FrameThe heavy-duty design of the rear frame can better stabilize the equipment when the working arm moves and the ore is crushed. The heavy-duty design of the rear frame and tail frame minimizes the damage from the impact of the tunnel wall.High-strength alloy steel plates are used to optimize material thickness, reduce deadweight, improve overall transport capacity, and prolong the life of the structure. The working mechanism boom adopts a box-type structure, which provides a strong ability to resist impact loads and is optimized to reduce stress and extend the service life of the boom.of GB-125-2800 are equipped with lubrication points, which are well designed, time-saving and labor-saving, easy to maintain and durable.Central hingeBearing connectionWorking armBox structureLubrication systemCentralized lubricationElectrical SystemMain Configurationdynamo28 V, 70 ABattery2 x 12 V, 1 00 Ahstarter6 kW, 24 VLighting and work lightsLED Light6 PCS in the cab2 PCS in rear rack1PCS cab reading lightSpeaker ConfigurationstandardReversing buzzerstandardRotating warning lightstandardIncluded safety featuresFire safetyPortable fire extinguisher4 kgCentralized fire extinguishing systemOptionalHot side-cold side designstandardExhaust pipe insulation cotton protectionOptionalEnergy IsolationMain power switch can be lockedstandard Manual pressure relief device for accumulatorstandardFront and rear rack locking devicestandardVehicle protection functionEngine belt break protection systemstandardNeutral brake parking protection systemstandardElectrical short circuit and overload protection systemstandard
