Technical SpecificationsDrive SystemThe whole machine is driven mechanically-hydraulically. Flywheel end of engine is connected with transfer case. The front of engine is connected with split flow pumps to supply power to the components as follows:1. crawler traveling devices2. conveyor and screw feeder 3. tamper4. hopper folded in & out, screed up & down and other cylinders action Traveling DeviceIt consists of gear box, transfer case, traveling clutch and chain transmission.The driven chain wheel activates the crawler.Weight Bearing ModeThere are two crawlers. Crawler patches are configured with rubber. Each crawler ground touch area is 3050*300mm.SteeringThe traveling clutch is operated by hydraulic cylinder. The brake can make the machine turn at original place. HopperThe capacity is 12 tons and operated by hydraulic cylinder for entire discharge. Push RollerThe roller can swing to push the truck rear wheels.ConveyorLeft and right conveyor is independently driven. Clutch is controlled by hydraulic cylinder.Feeder System The system uses screw feeder which blades are of high wearable material and are easily replaced. Electrical SystemThe system is equipped with two batteries. The voltage is 24V.CanopyHydraulic folding plastic canopy.Automatic Leveling SensorsIt has two longitudinal and one transverse leveling units, used for automatic adjustment of slope and grade.Working DevicesDouble hydraulic extension screed1.Screed basic width 3000mm Hydraulic extension to 5500mm Mechanical extension to 7500mm2.Vibration frequency 0~50Hz LTU70 Paving material applicationAsphalt RCCPaving projectExpress way and High grade roadUrban roadsRunway of airportPlaza and park Main Performance1. Solid and durable crawler's device, which offers powerful tractionThrust wheel can be adjusted by floating unit and machine's height to ensure driving smoothly, especially when paving on rough roadbed. Crawler traveling device is consisted of permanent lubricated thrust wheel and track shoes, which is durable, good adhesive and no easy slipping.2. Independent left & right conveyor and screw feederIndependent operation for L/R conveyor and screw feeder, easy operation. Screw feeder is extended mechanically. Screw feeder blade is made of wearable material, convenient replacement to ensure screw life.3. Centralized Lubrication System The system charges lubricating grease to all high temperature bearings automatically, which improves much the convey and feed reliability and reduces the failure rate maximally.4. Auto Leveling Units to offer Reliability for Road Smoothness The machine is equipped with two longitudinal and one transverse automatic leveling probes, which reaches the demand of high-grade road smoothness. It controls in time, convenient and intuitionistic. It can prevent the asphalt from valid filling to reduce construction cost.5. Extended ScreedScreed can be extended to meet different paving status, save the time of adjusting width of screed.6. Wide Eyeshot and Removable Operation PlatformAll the control elements centralize on operation platform for easy operation. Operation platform can be moved right and left that can reduce job of operator and improve efficiency to guarantee pavement qualityKey Parts Items | System | Components | Manufacturer |
