Zdl307 Underground Mining Bucket Capacity 3m³ Underground Loader¹

Product DescriptionThe ZDL307 Diesel Underground Loader mainly used in conjunction with mining trucks in underground excavation and mining operations. Shovel loading of ore and various materials can greatly improve operational efficiency and is an important equipment for achieving trackless mining.1. Technical Characteristics:Power System: Equipped with a Deutz air-cooled engine.Transmission: Utilizes a gearbox and torque converter. Braking System:             Driving Brake: Wet multi-disc spring brake with hydraulic release.             Parking Brake: Spring brake on the drive axle.Frame: Centrally hinged structure for improved adhesion performance.Steering:Hydraulic power steering with a single steering cylinder.2. Performance Highlights:Diesel Engine: Powered by a reliable diesel engine.Four-Wheel Drive: Ensures traction and maneuverability.Lateral Driving:Allows flexibility in tight spaces.Central Articulated Hydraulic Steering: Large steering angle for precise control.Small Turning Radius: Ideal for medium section tunnel operations.3. Safety Measures:Safety Gear: Operators must wear safety helmets, carry self-rescue devices, and use mining lamps when entering the well.Regular Maintenance: Regular inspections and prompt addressing of hidden dangers.No Maintenance During Operation: Strictly prohibited to conduct maintenance while the machine is running.Safety During Welding/Cutting:Confirm absence of flammable or explosive materials before maintenance.Exhaust Pipe Precautions: Avoid physical contact with the hot exhaust pipe.Hydraulic System Maintenance: Pressure must be relieved before starting any repairs.Usage Conditions for the ZDL307 Diesel Underground Loader1. Tunnel Specifications:Suitable for tunnels with a cross-sectional size of 4 meters (height) x4 meters (width) and above.Requires a firm top plate.Minimum turning radius of≥9 meters on the outside.Road slope should be≤ 14°.Adequate ventilation and drainage in the workplace.2. Environmental Factors:Ambient temperature within the tunnel:-5°C to 40℃. Maximum relative humidity (at 25°C): Not more than 85%.Altitude of usage location: Not exceeding 1000 meters.In high-altitude areas (above1000 meters), power reduction is required for operation.3. Fuel Requirements:The sulfur content of the fuel used in this machine must not exceed 0.2%.4.Safety Precautions:Strictly prohibited in places with flammable and explosive gases (such as gas and coal dust).ZDL307 Diesel Underground Loader:Technical specificationsTechnical parametersRated load capacity:7 t (Full load)Bucket capacity (stacking):3 m3Maximum driving speed    Levell:5.8 km/h    Level ll:9.7 km/h    Level lll: 15.1 km/h    LevelIV:20.5 km/hWorking hours:16 sMaximum climbing ability (heavy load): 25%Maximum traction force:160 kN Turning radius: Inner side 2800 mm0utside6000 mmMaximum machine height during unloading:1950mmMaximum unloading angle:40°Steering angle:±40°Ground clearance:280mmOverall dimensions:9250mmx2600 mmx2250mmOperating weight of the entire machine:19.5tEngineEngine: DEUTZ BF6M1013EC water-cooled low pollution engineRated power/rated speed:165kW/2200r/minStarting method: Electric startingExhaust gas purification method: catalytic purification methodThrottle control: Williams electronic throttle controllerTransmission systemTransmission model: DANA R32000 series automatic shift transmission;Torque converter model: DANA C270Drive axle model:DANA 16DFinal drive ratio: 6Wheel edge speed ratio:4.46Total speed ratio:26.77Tire: 17.5-25R smooth inflated steel wire tireBraking systemBrake pump:HPT1-16Displacement:16ml/rMaximum pressure of braking system: 19 MPaService brake: Wet multi disc spring brake brake valve model:MICOParking brake: spring brake on the drive axle, spring brake, hydraulic release brakeParking brake valve model: RA3/3/2/G-3Steering systemType: Central hinge,hydraulic steeringSteering work pump:DANFOSS ERL100 (shared by work) displacement:100ml/rMaximum pressure of steering system:14 MPaSteering cylinder diameter/rod diameter x Number of cylinders:φ100/φ55mm x twoSteering multi way valve:PVG100Working SystemWorking pump: DANFOSS ERL100Working directional valve:PVG100Lift cylinder diameter/rod diameter x Number of cylinders:φ 140/φ80mm x 2Bucket cylinder diameter/rod diameter x Number of cylinders:φ200/ φ110 mm x 1Maximum pressure of working system:25MPaElectrical SystemSystem voltage:24VDCStarting motor voltage/power:24V/6kWThe wiring harness is made of high-temperature resistant wires, and high-quality corrugated pipes are used around the wiring harnessLighting:2 front headlights,2 x 75W,24V2 rear headlights, 2x75W,24V2 cab ceiling lights, 24VTank volumeHydraulic oil tank:300LFuel tank: 200LTransmission:36LDrive axle main transmission part:17L x2Drive axle wheel reduction part: 3.5Lx4Engine lubricating oil:28LTECHNICAL DRAWING AND DIMENSIONSCompany ProfileQINGDAO ZONGDA MACHINERY CO., LTD is a professional manufacture focusing on research and development, production, sale and service of underground mining machinery, a solution supplier and a mining project contractor in China with strong comprehensive strength and rich experience in mining industry.We have more than 30 professional and experienced mining experts and engineers and 200 staff for R&D, Production, QC, After Sales Technical Support and etc.We have fulfilled our commitment to turn knowledge into value by delivering a comprehensive range of integrated equipment and services that cost-effectively transform ore bodies into high grade mineral products for customers.Packaging & ShippingFAQ1.
